Сигнал Hippo-YAP/TAZ в гематологических злоумышленниках: Молекулярные механизмы, тротуар и терапевтический потенциал.

Introduction

Hematological malignancies, including leukemia, lymphoma, and multiple myeloma (MM), comprise a heterogeneous group of clonal disorders arising from hematopoietic cells and remain a major cause of cancer-related morbidity and mortality worldwide. 1 , 2 Despite substantial progress in targeted therapy, immunotherapy, and supportive care, many patients still experience disease relapse, therapeutic resistance, and poor long-term outcomes, particularly in biologically aggressive or refractory subtypes. 3 , 4 Context-dependent functional heterogeneity of YAP/TAZ in hematological malignancies—where these effectors can act as either oncogenes or tumor suppressors depending on the specific lineage and microenvironment—has emerged as a critical consideration for therapeutic development. 5 These persistent clinical challenges underscore the urgent need to identify novel molecular mechanisms that drive malignant progression and treatment failure. 6 , 7

The Hippo pathway has garnered increasing attention due to its central role in regulating cell proliferation, apoptosis, stemness, and tissue homeostasis. 8 , 9 Dysregulation of this pathway, especially aberrant activation of its downstream transcriptional coactivators YAP and TAZ, has been increasingly implicated in hematological malignancy pathogenesis. 10 , 11 Growing evidence suggests that Hippo pathway dysfunction promotes malignant cell survival and proliferation. 12 , 13 Additionally, it contributes to chemoresistance, microenvironmental adaptation, and disease progression. 14 , 15 Therefore, a comprehensive understanding of Hippo signaling may provide important mechanistic insights and reveal new opportunities for precision-targeted therapeutic intervention in hematological cancers. 16 , 17 Although numerous reviews have comprehensively summarized the role of Hippo signaling in solid tumors and general cancer biology, a focused synthesis of its involvement in hematological malignancies remains limited. In particular, recent discoveries regarding the context-dependent functions of YAP/TAZ, extensive signaling crosstalk, and emerging Hippo-targeted therapeutic strategies have not been systematically integrated within the framework of hematologic cancers.

In this review, we specifically focus on the molecular mechanisms and biological functions of Hippo signaling in hematological malignancies. We summarize current evidence regarding pathway dysregulation in leukemia, lymphoma, and multiple myeloma, discuss interactions with major oncogenic signaling networks, evaluate emerging therapeutic strategies and clinical advances, and highlight future opportunities for precision medicine in hematologic cancers.

Molecular Mechanisms of the Hippo Signaling Pathway

Core Components

The Hippo signaling pathway exerts its biological functions via an evolutionarily conserved serine/threonine kinase cascade and downstream transcriptional regulatory modules, which collectively regulate cell proliferation, apoptosis, differentiation, and tissue homeostasis in hematopoietic lineages. Its core kinase module consists of Mammalian sterile 20-like kinases 1 and 2 (MST1/2) and Large tumor suppressor kinases 1 and 2 (LATS1/2): as upstream initiators, MST1/2 phosphorylate and activate LATS1/2 upon recruitment of scaffold proteins; activated LATS1/2 then induce inhibitory phosphorylation of YAP/TAZ—the key downstream effectors of the pathway. 18 Scaffold proteins are essential for the assembly and activation of the Hippo core kinase complex in hematopoietic cells. Salvador family WW domain-containing protein 1 (SAV1), a classic scaffold protein, bridges MST1/2 and LATS1/2 to enhance their physical interaction and kinase activation. 19 In contrast, CORO7—a newly identified scaffold protein—binds to LATS1 and MST2 to promote formation of functional core kinase complexes. 18 This enhances the efficiency and specificity of Hippo signaling in hematopoietic homeostasis. Loss of these scaffold proteins impairs Hippo kinase complex assembly in hematopoietic cells. Consequently, YAP/TAZ phosphorylation is reduced, leading to their aberrant nuclear accumulation. This promotes oncogenic transcriptional programs and drives malignant transformation of hematopoietic progenitors.

In the inactive state of the Hippo pathway, unphosphorylated YAP/TAZ translocate to the nucleus and bind to TEAD1-4 transcription factors, thereby driving the expression of oncogenic target genes associated with hematopoietic cell proliferation (eg., CCND1, MYC) and anti-apoptosis (eg., BCL2). 20 Beyond canonical cell growth regulation, the Hippo pathway plays a unique role in hematopoietic innate immunity and inflammatory responses: innate immune and proinflammatory signals in the hematopoietic microenvironment activate the Hippo pathway via the Tak1-STRIPAK-Tao axis, which modulates cell fate decisions in hematopoietic lineages and maintains hematopoietic tissue homeostasis under inflammatory stress. 13 Collectively, the core Hippo components (MST1/2, LATS1/2, YAP/TAZ) and scaffold proteins (SAV1, CORO7) form a complex regulatory network that integrates multiple extracellular signals in the hematopoietic microenvironment to govern physiological and pathological processes of hematopoietic cells.

Regulation of YAP/TAZ

YAP/TAZ are the key downstream effectors of the Hippo pathway in hematological malignancies, and their subcellular localization and transcriptional activity are tightly regulated by phosphorylation, degradation, and hematopoietic microenvironment-specific mechanical/metabolic signals. The canonical regulatory mechanism is mediated by the MST1/2-LATS1/2 kinase cascade: LATS1/2 directly phosphorylate YAP at Ser127 and TAZ at Ser89 in hematopoietic cells, which promotes 14-3-3 protein binding to YAP/TAZ, sequestering them in the cytoplasm and abrogating their nuclear translocation. 21 Additionally, LATS1/2-induced phosphorylation of YAP at Ser381 triggers subsequent CK1-mediated phosphorylation, leading to ubiquitination and proteasomal degradation of YAP in malignant hematopoietic cells. 22

Independent of the MST1/2-LATS1/2 cascade, YAP/TAZ activity in hematological malignancies is modulated by mechanical and metabolic signals unique to the hematopoietic microenvironment. Mechanical cues from bone marrow stromal matrix stiffness and altered cytoskeletal architecture modulate YAP/TAZ nuclear translocation. This occurs via Rho GTPases and actin cytoskeleton remodeling. Specifically, increased bone marrow ECM stiffness drives F-actin polymerization, which inhibits LATS1/2 activity. Consequently, YAP/TAZ undergo aberrant activation in leukemia and multiple myeloma cells. 23 Metabolic signals, a hallmark of malignant hematopoietic cell reprogramming, also play a critical role in YAP/TAZ regulation: AMP-activated protein kinase (AMPK), a cellular energy sensor, directly phosphorylates YAP/TAZ to inhibit their transcriptional activity in glycolysis-dependent hematological malignant cells. 24 Hexokinase 2 (HK2), a key glycolytic enzyme overexpressed in multiple myeloma and acute myeloid leukemia (AML) cells, links aerobic glycolysis to YAP/TAZ activation in malignant hematopoietic cells, highlighting the metabolic-Hippo crosstalk that sustains the survival of hematological tumor cells.

YAP/TAZ predominantly exert oncogenic functions in many hematological malignancies. Although this is generally the case, notable exceptions exist. TAZ exhibits context-dependent functional dichotomy in hematological malignancies, acting as a tumor suppressor in multiple myeloma by downregulating MYC expression, in contrast to its oncogenic role in leukemia and most lymphomas. 25 , 26 These alterations are closely associated with tumorigenesis, disease progression, and chemoresistance. 18 Notably, YAP/TAZ display hematopoietic context-dependent functional heterogeneity: their biological roles are strictly influenced by hematopoietic cell lineage, bone marrow/lymph node tumor microenvironment, and co-expression of other oncogenic factors. TAZ exemplifies this functional dichotomy: it acts as a tumor suppressor in multiple myeloma by downregulating MYC expression—a stark contrast to its oncogenic role in leukemia and most lymphomas. 26 Elucidating the precise lineage- and microenvironment-specific regulatory mechanisms of YAP/TAZ in hematological malignancies is therefore critical for the development of subtype-specific targeted therapeutic strategies ( Figure 1 ). Figure 1 Nuclear translocation of YAP/TAZ and downstream transcriptional activation following Hippo pathway suppression.Under physiological conditions, the Hippo core kinase cascade (MST1/2–SAV1–LATS1/2–MOB1A/B) remains active and induces inhibitory phosphorylation of YAP and TAZ, leading to their cytoplasmic retention through 14-3-3 binding. Phosphorylated YAP is further subjected to CK1-mediated phosphorylation and ubiquitin-dependent proteasomal degradation. Upon Hippo pathway inactivation, triggered by mechanical stress, growth factor stimulation, or GPCR signaling, unphosphorylated YAP/TAZ translocate into the nucleus and interact with TEAD1–4 transcription factors. This process promotes the transcription of genes involved in cell-cycle progression, proliferation, and anti-apoptotic signaling, including CCND1, MYC, and BCL2, thereby driving malignant hematopoietic cell survival. Diagram of Hippo-Kinase cascade states, YAP/TAZ regulation, phosphorylation and gene expression. The image shows a diagram of the Hippo-Kinase cascade in two states: OFF and ON. On the left, the OFF state involves mechanical stress, integrins and GPCR activating pathways through Crumbs, KIBRA, PI3K and ERK. Mst1/2 and SAV1 interact with Lats1/2 and Mob1A/B, leading to YAP/TAZ activation. YAP/TAZ translocate to the nucleus, promoting gene expression with TEAD1-4. On the right, the ON state shows GPCR and RASSF1A activating Mst1/2 and SAV1, leading to Lats1/2 and Mob1A/B phosphorylation of YAP/TAZ. Phosphorylated YAP is retained in the cytoplasm by 14-3-3, preventing gene expression. Ubiquitination leads to YAP degradation. The diagram includes interactions with β-catenin, AMOTs and PTPN14, affecting tight junctions and adherens junctions through E-cadherin and α-catenins. The pathways illustrate the regulation of gene expression and cellular localization of YAP/TAZ in response to mechanical and signaling inputs.

Hippo Pathway Cross-Talk with Other Signaling Pathways

The Hippo pathway does not act as an independent regulatory network but engages in extensive crosstalk with other key oncogenic signaling cascades, forming a complex regulatory network that regulates cell fate decisions and tumorigenesis. The crosstalk between the Hippo pathway and TGF-β, Wnt/β-catenin, PI3K/Akt, and Notch pathways has been well characterized, and these interactions play critical roles in hematological malignancies.

TGF-β/Mothers Against Decapentaplegic Homolog (Smad) Signaling

YAP/TAZ can bind to Smad proteins and enhance their transcriptional activity, thereby amplifying TGF-β/Smad signalin g . 13 TGF-β can also upregulate TAZ expression, forming a positive feedback loop that promotes fibrosis and epithelial-mesenchymal transition (EMT). 13 In hematological malignancies, this crosstalk may contribute to the malignant transformation of hematopoietic cells and the remodeling of the tumor microenvironment.

Wnt/β-Catenin Signaling

TAZ acts as a transcriptional coactivator of β-catenin, enhancing the expression of Wnt target gene s . 27 The hierarchical crosstalk between the Hippo, TGF-β, and Wnt pathways regulates the switch between proliferative and invasive cellular phenotypes in tumor s . 27 Dysregulation of any of these pathways can affect the function of the others, accelerating tumor progression.

PI3K/Akt Signaling

This is the most well-characterized crosstalk partner of the Hippo pathway in cancer biology. PI3K/Akt signaling can directly inhibit LATS1/2 activity, leading to YAP/TAZ activatio n . 28 Vascular endothelial growth factor receptor (VEGFR) can regulate the Hippo pathway via PI3K/Mitogen-activated protein kinase (MAPK) activation, further linking angiogenesis to Hippo signalin g . 28 This crosstalk is particularly important in hematological malignancies, as PI3K/Akt activation is a common oncogenic event that contributes to YAP/TAZ-mediated chemoresistance.

Notch Signaling

Notch1 signaling can upregulate YAP/TAZ expression in endothelial cells, and knockdown of Notch1 leads to reduced YAP/TAZ level s . 13 In hematological malignancies, the Notch pathway is frequently dysregulated in T-cell leukemia and lymphoma, and its crosstalk with the Hippo pathway may play a critical role in malignant cell survival and proliferation.

In addition, metabolic signals and non-coding RNAs act as key mediators of the crosstalk between the Hippo pathway and other signaling cascades. 13 This complex crosstalk network underscores the importance of understanding Hippo pathway regulation in hematological malignancies, as single-target therapies may be limited by compensatory activation of other oncogenic pathways ( Figure 2 and Table 1 ). Importantly, such multilayered crosstalk creates a highly adaptive signaling network that may underlie therapeutic resistance and limit the efficacy of single-pathway-targeted strategies. Table 1 Crosstalk Between Hippo Pathway and Major Oncogenic Signaling Pathways Pathway Interaction Mechanism Effect on YAP/TAZ Functional Outcome PI3K/AKT Inhibits LATS1/2 Activates YAP/TAZ Proliferation, resistance Wnt/β-catenin TAZ coactivates β-catenin Enhances transcription Tumor progression TGF-β/Smad YAP binds Smad Amplifies signaling EMT, microenvironment remodeling Notch Upregulates YAP/TAZ Promotes activation Cell survival Metabolic (AMPK/HK2) Phosphorylation / glycolysis coupling Context-dependent Energy adaptation Abbreviations : AMPK, adenosine 5′-monophosphate-activated protein kinase; EMT, epithelial-mesenchymal transition; HK2, hexokinase 2.Ref: 13 , 27–29 . Figure 2 Crosstalk between Hippo signaling and major oncogenic pathways in hematological malignancies Dysregulated YAP/TAZ signaling extensively interacts with multiple oncogenic pathways. YAP/TAZ enhance TGF-β/Smad signaling through direct association with Smad proteins, strengthen Wnt/β-catenin signaling by functioning as transcriptional coactivators, and are positively regulated by PI3K/AKT signaling through LATS1/2 inhibition. In addition, Notch signaling can increase YAP/TAZ expression and amplify their oncogenic activity. Metabolic reprogramming, particularly glycolysis-related pathways, further contributes to aberrant Hippo signaling activation. These interconnected signaling networks collectively promote malignant proliferation, invasive phenotypic transition, microenvironmental adaptation, and disease progression in hematological cancers.

Hippo Pathway in Hematological Malignancies

Leukemias

The Hippo pathway plays a pivotal role in the regulation of normal hematopoiesis, and its dysregulation is closely associated with the initiation and progression of various leukemias. Genetic and epigenetic alterations in core Hippo pathway components are commonly detected in leukemic cells. Specifically, MST1/2 and LATS1/2 are frequently deleted or transcriptionally downregulated. In acute myeloid leukemia, RHOBTB2 enhances cell proliferation by stabilizing KLHL13, which inhibits Hippo pathway activity and activates YAP/TAZ transcriptional coactivators, thereby revealing a previously unrecognized RHOBTB2-KLHL13-Hippo axis in AML pathogenesis. 30 This leads to aberrant nuclear accumulation of YAP/TAZ and subsequent activation of oncogenic target genes. 18 This dysregulation drives the malignant transformation of hematopoietic stem/progenitor cells by promoting cell proliferation, inhibiting apoptosis, and impairing cellular differentiation.

The crosstalk between the Hippo pathway and other oncogenic signaling cascades further exacerbates leukemogenesis. For example, the PI3K/Akt pathway, which is commonly activated in acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL), can inhibit LATS1/2 activity and enhance YAP/TAZ activation. 28 Innate immune and proinflammatory signals in the leukemic microenvironment can also modulate Hippo pathway activity via the Tak1-STRIPAK-Tao axis, influencing cell fate decisions in hematopoietic lineages and promoting leukemic cell survival. 13 , 31 Functional studies have confirmed the oncogenic role of YAP in leukemia: knockdown of YAP in Jurkat cells (a human T-cell leukemia cell line) significantly inhibits cell proliferation and induces apoptosis, and YAP inhibition enhances the therapeutic responsiveness of leukemic cells to conventional chemotherapeutic agents. 31 , 32

Notably, the Hippo pathway is also involved in the development of therapeutic resistance in leukemia: YAP1 activity confers survival benefits to leukemic cells under chemotherapy stress, and targeting YAP may be a promising strategy to overcome refractoriness to standard treatments. 32 In chronic myeloid leukemia, Hippo-YAP signaling is involved in imatinib resistance in Chronic myeloid leukemia (CML), and ectopic overexpression of STK4 enhances imatinib-induced apoptosis of CML cells. 33 , 34 Furthermore, LATS2 expression is decreased in highly drug-resistant leukemic cells and is associated with unfavorable prognosis. 25 Preclinical studies have shown that small-molecule agents targeting the Hippo pathway (eg., YAP/TAZ inhibitors) can effectively induce apoptosis in leukemic cells and inhibit tumor growth in xenograft models. 18 These findings confirm the Hippo pathway as a potential therapeutic target in leukemia, especially for refractory subtypes. Collectively, these findings support the Hippo pathway as a critical driver of leukemogenesis and a promising therapeutic target, particularly in treatment-resistant disease.

Lymphomas

Lymphomas are a heterogeneous group of B-cell or T-cell malignancies, and the Hippo pathway has emerged as a key regulator of lymphoma progression and therapeutic resistance. “Dysregulation of the Hippo pathway, characterized by YAP/TAZ overexpression or nuclear accumulation, has been documented in major lymphoma subtypes, including Diffuse large B-cell lymphoma (DLBCL) and natural killer/T-cell lymphoma (NK/TCL), and correlates with tumor aggressiveness and poor clinical outcomes. 35

In DLBCL—the most common non-Hodgkin lymphoma subtype—Hippo pathway dysregulation underlies rituximab resistance. Rituximab is a key component of standard first-line immunochemotherapy regimens for DLBCL. Notably, Semaphorin-3F, a secreted protein, can downregulate YAP/TAZ expression and restore rituximab sensitivity in DLBCL cells. This suggests that modulating the Hippo pathway may enhance the efficacy of anti-CD20 antibody therapy. 35 Genetic alterations in Hippo pathway components (eg., LATS) are also common in B-cell lymphomas, and concurrent alterations of TP53 and Hippo pathway components lead to markedly poorer prognosis, suggesting that concurrent inactivation of the Hippo pathway and p53 signaling accelerates lymphoma progression. 36 In NK/TCL, a highly aggressive lymphoma subtype, activation of MST1/2 significantly inhibits cell proliferation and induces apoptosis by suppressing YAP activity, confirming the therapeutic potential of Hippo pathway activation in aggressive lymphomas. 37

Metabolic and oxidative stress signals also modulate Hippo pathway activity in lymphomas: increased reactive oxygen species (ROS) levels can activate MST1, strengthen Hippo signaling, and drive cell death in lymphoma cells. 37 ROS function as both signaling molecules and cell death inducers. This dual role reveals the intricate link between cellular metabolism and the Hippo pathway in lymphoma biology. In addition, non-coding RNAs have emerged as important regulators of Hippo signaling in lymphoma. For example, hsa_circ_0000877 promotes DLBCL progression through the miR-370-3p/MAP4K4/Hippo signaling axis, highlighting the potential of non-coding RNA (ncRNA)-mediated Hippo regulation as a therapeutic target in lymphoma. 38 Collectively, these findings confirm the critical role of the Hippo pathway in lymphoma pathogenesis and highlight its potential as both a prognostic biomarker and a therapeutic target. These observations highlight the Hippo pathway as both a prognostic biomarker and a potential therapeutic vulnerability in lymphoma.

Myelomas

Multiple myeloma (MM) is a plasma cell malignancy characterized by clonal expansion of abnormal plasma cells in the bone marrow. Hippo pathway dysregulation represents a pivotal mechanism underlying MM development, progression, and chemoresistance. Excessive YAP expression is a common event in MM cells and is associated with enhanced cell proliferation, survival, and resistance to conventional chemotherapeutic agents. 26 Transcriptomic analysis of ~1000 MM patients from the CoMMpass study demonstrated that TAZ expression significantly decreases during disease progression from stage 1 to stage 3, showing an inverse correlation with disease severity. High TAZ expression is strongly associated with better prognosis in MM patients, further supporting its tumor-suppressive function in this malignancy. 25 The functional role of YAP/TAZ in MM is complex and context-dependent: YAP functions as an oncogene by promoting MM cell proliferation and survival, whereas TAZ exhibits tumor-suppressive activity by downregulating MYC expression, revealing the functional heterogeneity of Hippo effectors in MM. 26

The crosstalk between the Hippo pathway and metabolic pathways is a key regulatory mechanism in MM. PLA2G16, a lipid metabolism-related gene, modulates Hippo/YAP signaling in MM cells: inhibition of PLA2G16 leads to cell cycle arrest and apoptosis, and impairs glucose metabolism reprogramming in MM cells. 39 This finding reveals the intricate link between lipid metabolism and the Hippo pathway, providing a basis for dual-target therapy targeting metabolic pathways and the Hippo pathway in MM. Non-coding RNAs also critically regulate the Hippo pathway in MM. For instance, long non-coding RNA (lncRNA) MALAT1 functions as a competing endogenous RNA (ceRNA) that sponges miR-181a-5p, thereby modulating Hippo-YAP signaling and promoting multiple myeloma cell proliferation and adhesion. 40 This lncRNA-microRNA (miRNA)-Hippo axis forms a complex regulatory network that modulates MM cell behavior, and targeting this axis has shown promising preclinical efficacy.

YAP/TAZ are also involved in the regulation of oxidative stress responses in MM: TAZ can upregulate miR-224 to inhibit oxidative stress responses, thereby promoting MM cell survival. 41 This finding further expands the functional scope of the Hippo pathway in MM and suggests that targeting the Hippo-oxidative stress axis may be a novel therapeutic strategy. Preclinical studies have confirmed that reactivation of the Hippo pathway can effectively inhibit MM cell growth and induce apoptosis, and combining Hippo pathway modulators with conventional chemotherapeutic agents or proteasome inhibitors may overcome chemoresistance in MM 26 ( Table 2 ). Overall, Hippo pathway dysregulation represents a key mechanism underlying MM progression and drug resistance, supporting its relevance as a therapeutic target.

Context-Dependent Functions of YAP and TAZ

Accumulating evidence suggests that the biological functions of YAP and TAZ in hematological malignancies are highly context-dependent and cannot be simply categorized as uniformly oncogenic. 42 , 43 While YAP/TAZ activation generally promotes proliferation, survival, and therapeutic resistance in many hematologic cancers, emerging studies indicate that these transcriptional coactivators may exert tumor-suppressive functions in specific cellular contexts. 29 , 42 , 43

In leukemia and lymphoma, YAP/TAZ are predominantly considered oncogenic drivers. 44–46 Elevated YAP expression has been associated with enhanced proliferation, inhibition of apoptosis, and poor clinical outcomes in acute myeloid leukemia (AML), diffuse large B-cell lymphoma (DLBCL), and T-cell acute lymphoblastic leukemia (T-ALL). 45 , 47 Mechanistically, YAP/TAZ cooperate with TEAD transcription factors to induce the expression of genes involved in cell-cycle progression, metabolic adaptation, and survival signaling, thereby facilitating malignant transformation and disease progression. 29 , 44 , 48

In contrast, studies in multiple myeloma (MM) have revealed a more complex regulatory landscape. 26 , 46 Grieve et al demonstrated that TAZ functions as a tumor suppressor in MM by repressing MYC expression and limiting malignant plasma-cell growth. Loss of TAZ expression was associated with enhanced tumor progression, highlighting a biological role distinct from that observed in many other malignancies. 26 Similarly, previous investigations have suggested that activation of specific Hippo pathway components may promote apoptosis rather than tumor growth in selected hematologic contexts. 26 , 44 , 49

These observations emphasize that the functional consequences of Hippo pathway dysregulation depend on cellular lineage, genetic background, and microenvironmental factors. 44 , 46 , 50 Therefore, therapeutic strategies targeting YAP/TAZ should be carefully tailored according to disease subtype. 29 , 43 While YAP/TAZ inhibition may represent a promising approach for leukemia and lymphoma, indiscriminate suppression of Hippo signaling could be detrimental in malignancies where TAZ exerts tumor-suppressive functions. 26 , 46 , 49 A more comprehensive understanding of the context-specific biology of YAP/TAZ will be essential for the development of precision Hippo-targeted therapies. 44 , 50

Molecular Evidence

Accumulating molecular and clinical evidence has confirmed the critical role of the Hippo pathway in the pathogenesis of hematological malignancies, and YAP/TAZ have emerged as key molecular biomarkers and therapeutic targets. Systematic molecular profiling studies have revealed that genetic alterations in Hippo pathway-related genes (eg., MST1/2, LATS1/2, YAP/TAZ) are common across various hematological malignancies, and these alterations are closely associated with disease stage and prognosis. 18 , 45 For example, abnormal YAP expression is a key driver of DLBCL progression, and YAP expression level can serve as a prognostic biomarker for DLBCL patients. 45

Functional studies have confirmed the causal relationship between Hippo pathway dysregulation and hematological malignancies: Wang et al found that Hippo pathway alterations are associated with the malignant transformation of hematopoietic cells, and YAP/TAZ overexpression is sufficient to promote the formation of hematological tumors in animal models. 18 Zhou et al elucidated the specific mechanism by which IGF-1R regulates DLBCL tumorigenesis via the Hippo-YAP pathway, confirming the Hippo pathway as a downstream effector of oncogenic receptors in lymphoma. 45 In myeloproliferative neoplasms (MPNs), the expression of Hippo pathway-related genes is significantly deregulated, and these alterations are associated with the abnormal proliferation of hematopoietic cells. 51

Targeted inhibition of YAP/TAZ has shown promising preclinical efficacy in hematological malignancies. Verteporfin, a small-molecule agent that disrupts the YAP-TEAD interaction, can effectively inhibit the transcriptional activity of YAP in various cancer cell lines, including hematological malignant cells. 45 Non-coding RNAs also provide potential therapeutic targets: miR-103a-3p can regulate the Hippo/YAP axis to inhibit tumor glycolysis in solid tumors, and this mechanism may be conserved in hematological malignancies. 52 These molecular findings not only confirm the Hippo pathway as a key oncogenic driver in hematological malignancies but also provide a wealth of potential molecular targets for the development of novel targeted therapies ( Figure 3 ). Figure 3 Hippo pathway dysregulation and context-dependent YAP/TAZ functions across major hematological malignancies Genetic and epigenetic alterations, together with oncogenic signaling crosstalk and microenvironmental cues, contribute to Hippo pathway dysregulation in leukemia, lymphoma, and multiple myeloma. In leukemia and lymphoma, loss of upstream Hippo kinase activity promotes YAP/TAZ nuclear accumulation and TEAD-dependent transcription, resulting in enhanced proliferation, survival, drug resistance, and disease progression. In multiple myeloma, Hippo signaling exhibits context-dependent regulation, with YAP frequently acting as an oncogenic factor whereas TAZ may exert tumor-suppressive functions through repression of MYC-associated programs.Symbols: ↓, inhibition, loss, or downregulation; →, activation, signaling transmission, or downstream biological effect; ⊣, inhibitory regulation; P, phosphorylation; dashed lines/arrows indicate indirect regulation or multistep signaling events; dashed blunt-ended lines indicate indirect inhibitory regulation rather than direct molecular interactions. Infographic: Hippo pathway dysregulation in blood cancers, showing genetic changes and effects. The infographic illustrates Hippo pathway dysregulation across leukemia, lymphoma and multiple myeloma. In leukemia, genetic/epigenetic alterations such as MST1/2, LATS1/2, SAV1, or scaffold proteins lead to Hippo pathway dysregulation. Oncogenic signaling crosstalk involves PI3K/AKT, TGF-beta, Wnt, Notch and inflammatory cues. This results in YAP/TAZ activation, target gene transcription (CCND1, MYC, BCL2, Survivin) and oncogenic outcomes like proliferation, survival, self-renewal, chemoresistance and disease progression. In lymphoma, similar genetic alterations and microenvironmental cues lead to aggressive behavior, immune evasion and poor prognosis. In multiple myeloma, complex genetic alterations and bone marrow microenvironment influence context-dependent regulation. YAP activation leads to oncogenic outcomes, while TAZ suppression results in tumor-suppressive outcomes, including inhibition of MYC and reduced progression. Target genes include CCND1, BCL2, CTGF and CYR61.

Therapeutic Implications

Targeting the Hippo Pathway in Cancer Therapy

Targeting the Hippo pathway has emerged as a promising therapeutic strategy for cancer, and preclinical studies have demonstrated its therapeutic potential in hematological malignancies. The therapeutic strategies for targeting the Hippo pathway can be divided into two main categories: direct targeting of YAP/TAZ and indirect targeting via upstream regulators or pathway crosstalk.

Direct targeting of YAP/TAZ focuses on inhibiting their transcriptional activity or nuclear translocation. Verteporfin is the most well-characterized YAP inhibitor. Originally developed as a photosensitizer for age-related macular degeneration, it disrupts the YAP-TEAD interaction and inhibits YAP-mediated transcriptional activity. 5 Insights into the dual role of YAP/TAZ in hematological malignancies suggest that therapeutic strategies may require disease-specific tailoring. YAP activation rather than inhibition may prove beneficial in certain hematologic cancers where YAP functions as a tumor suppressor. 5 Although verteporfin has shown promising preclinical efficacy in hematological malignant cell lines, its clinical application is limited by phototoxicity and poor stability, highlighting the need for the development of more specific and potent YAP/TAZ inhibitors. 53 First-generation TEAD inhibitors have been developed. These agents target the YAP-TEAD binding interface or the TEAD palmitoylation site. They have shown efficacy in preclinical models of tumors with high YAP/TAZ activity. Their efficacy in hematological malignancies is currently under investigation. 17 , 54

Indirect targeting of the Hippo pathway via upstream regulators provides an alternative strategy. Scaffold proteins (eg., SAV1, CORO7) and kinases (eg., MST1/2, LATS1/2) are potential upstream targets: restoring the expression or activity of these components can reactivate the Hippo tumor-suppressive kinase cascade. 18 Phosphatases also play important roles in Hippo pathway regulation. Recent studies identified PTPN12 as a novel negative regulator of YAP/TAZ, and restoration of PTPN12 activity suppresses YAP/TAZ-mediated proliferation and migration in cancer cells, highlighting its potential therapeutic relevance. 55 Non-coding RNAs also provide indirect targeting opportunities: targeting lncRNA MALAT1 or restoring miR-181a-5p expression can inhibit YAP activity in MM cells, and this strategy can be extended to other hematological malignancies with dysregulated non-coding RNA-Hippo axes. 56

Combination therapy targeting the Hippo pathway and its crosstalk partners is a promising direction to overcome therapeutic resistance. The Hippo pathway interacts extensively with the PI3K/Akt, MAPK, and Notch pathways in hematological malignancies, and simultaneous inhibition of the Hippo pathway and these cascades can produce a synergistic anti-tumor effect. 13 For example, combining YAP inhibitors with PI3K/Akt inhibitors can effectively inhibit the growth of AML cells with concurrent activation of PI3K/Akt and YAP. 28 In addition, combining Hippo pathway modulators with conventional chemotherapeutic agents or immunotherapies (eg., rituximab, CAR-T therapy) may enhance their efficacy and overcome chemoresistance/immunoresistance in hematological malignancies. 35

Clinical Trials and Drug Development

The rapid evolution of Hippo-targeted therapeutics has significantly accelerated the translational potential of this pathway in oncology. Although hematological malignancy-specific clinical trials remain limited, recent advances in solid tumors provide important proof-of-concept evidence supporting future extension into hematologic cancers. A Phase 1b/2a trial evaluated bemcentinib (BGB324), a first-in-class AXL receptor tyrosine kinase inhibitor downstream of YAP/TAZ, in combination with low-dose cytarabine in acute myeloid leukemia patients unfit for intensive chemotherapy, demonstrating the feasibility of targeting YAP/TAZ downstream effectors in hematologic malignancies. 57 In particular, TEAD palmitoylation inhibitors have emerged as the most clinically advanced class of Hippo-targeted agents, directly suppressing YAP/TAZ-driven transcriptional programs. 58

Among these, VT3989 is currently the leading first-in-class oral TEAD inhibitor. In the first-in-human phase 1/2 trial involving refractory solid tumors, especially mesothelioma, VT3989 demonstrated manageable toxicity, durable disease control, and clear early clinical proof-of-concept for pharmacologic blockade of the Hippo–YAP–TEAD axis. 58 Importantly, the objective response rate reached 32% at clinically optimized dosing, with a disease control rate of 86%, highlighting the feasibility of TEAD inhibition in advanced malignancies. 59 These findings strongly support the rationale for extending TEAD inhibitors into relapsed or refractory hematological malignancies characterized by YAP/TAZ hyperactivation. 58 Notably, most current clinical evidence is derived from solid tumors, highlighting a critical gap in hematological malignancy-specific clinical validation and underscoring the need for dedicated clinical studies in this field.

Another promising agent, IK-930, has completed first-in-human Phase I evaluation in advanced solid tumors and further validates TEAD as a druggable transcriptional dependency node. 60 Although these agents are currently evaluated mainly in solid tumors, their mechanistic relevance is highly translatable to hematological malignancies, particularly diffuse large B-cell lymphoma, acute leukemia, and multiple myeloma, where aberrant YAP/TAZ signaling contributes to survival advantage and therapeutic resistance. 5

Beyond direct TEAD inhibition, future drug development is increasingly shifting toward rational combination strategies, including co-targeting PI3K/AKT, mTOR, MAPK, and immune checkpoint pathways. 59 Given the extensive signaling crosstalk described in hematologic cancers, combination regimens integrating Hippo pathway inhibitors with rituximab, proteasome inhibitors, BCL-2 inhibitors, or CAR-T–based immunotherapy may provide superior efficacy and overcome adaptive resistance. 59 These combination paradigms are particularly attractive for biomarker-enriched patient subsets with elevated nuclear YAP/TAZ activity. Recent clinical advances therefore indicate that Hippo pathway modulation is transitioning from a conceptual target into a clinically actionable therapeutic strategy 61 ( Figure 4 ; Table 3 ). However, hematological malignancy-specific trials remain urgently needed.

An infographic on targeting Hippo signaling shows upstream regulators like phosphatases and miRNAs restoring Hippo activity. Active Hippo involves MST/LATS phosphorylating YAP/TAZ for cytoplasmic retention, while dysregulated Hippo sees nuclear YAP/TAZ binding TEAD, promoting tumor growth. Verteporfin blocks YAP-TEAD interaction. Intervention strategies include small-molecule YAP-TEAD inhibitors and YAP/TAZ inhibition. Phosphatases like PTPN12 and MYPT1 restore Hippo activity and combining Hippo inhibitors with MAPK inhibitors can overcome resistance. Outcomes include reduced tumor progression and improved HRQOL.

Challenges and Opportunities

Although targeting the Hippo pathway holds great promise for the treatment of hematological malignancies, there are several critical challenges that need to be addressed for successful clinical translation, along with promising opportunities to overcome these barriers.

Key Challenges

Context-Dependent Functional Heterogeneity of YAP/TAZ

YAP/TAZ can act as both oncogenes and tumor suppressors in hematological malignancies depending on the cell type and tumor microenvironment. 13 For example, TAZ is a tumor suppressor in MM but an oncogene in most lymphomas and leukemias. This functional heterogeneity makes it difficult to develop universal Hippo-targeted therapies and requires subtype-specific treatment strategies.

Clinical Translation Barriers of TEAD and YAP/TAZ Inhibitors

Recent early-phase clinical advances of TEAD inhibitors such as VT3989 and IK-930 have provided proof-of-concept for targetability; however, hematological malignancy-specific efficacy, long-term safety, and resistance mechanisms remain largely undefined. YAP/TAZ are intrinsically disordered proteins with no well-characterized binding pockets, making it challenging to develop small-molecule inhibitors with high specificity and potency. 53 Current inhibitors (eg., verteporfin) have limitations such as off-target effects and poor pharmacokinetic properties, and novel drug development strategies (eg., PROTACs, peptide inhibitors) are needed. 53

Compensatory Activation of Other Signaling Pathways

The extensive crosstalk between the Hippo pathway and other oncogenic cascades (eg., PI3K/Akt, Wnt/β-catenin) leads to compensatory activation of these pathways upon Hippo pathway inhibition, resulting in therapeutic resistance. Single-target therapies are thus likely to be ineffective, and combination therapies are required.

Lack of Validated Clinical Biomarkers

Potential biomarkers may include nuclear YAP/TAZ localization, TEAD target gene signatures, pathway mutation profiles, and dynamic liquid biopsy–based monitoring approaches.Although YAP/TAZ expression is associated with prognosis in hematological malignancies, there are no validated clinical biomarkers to select patients who are most likely to benefit from Hippo-targeted therapies. 13 The development of reliable biomarkers is critical for the clinical translation of Hippo-targeted therapies.

Promising Opportunities

Advances in Molecular Characterization and Precision Medicine

High-throughput sequencing and multi-omics analysis have enabled the comprehensive characterization of Hippo pathway alterations in individual patients, providing a basis for subtype-specific and personalized Hippo-targeted therapies. 13 Machine learning and bioinformatics can integrate multi-omics data to predict patient response to Hippo-targeted therapies and identify potential combination targets. 13

Novel Drug Development Strategies

Novel drug development approaches such as PROTACs, antibody-drug conjugates (ADCs), and gene therapy are being applied to target the Hippo pathway. For example, PROTACs targeting YAP/TAZ can achieve selective degradation of these proteins, and gene therapy to restore LATS1/2 expression is being explored in preclinical models. 53

Combination Therapy with Existing Standard Treatments

Future rational combinations may include TEAD inhibitors with rituximab in DLBCL, BCL-2 inhibition in leukemia, or proteasome inhibitors in multiple myeloma.Combining Hippo-targeted therapies with conventional chemotherapeutic agents, immunotherapies, or other targeted agents can produce a synergistic anti-tumor effect and overcome therapeutic resistance. 35 For example, combining YAP inhibitors with rituximab can restore sensitivity in refractory DLBCL. 35

Exploitation of the Tumor Microenvironment

The Hippo pathway regulates the interaction between tumor cells and the tumor microenvironment (eg., stromal cells, immune cells). 14 Targeting the Hippo pathway in the tumor microenvironment can modulate immune cell infiltration and activation, enhancing the efficacy of immunotherapies. 14 This provides a new direction for the development of Hippo-targeted therapies in combination with immunotherapy.

Future Directions

Emerging Research Areas Focused on Hematological Malignancies

Functional Heterogeneity of YAP/TAZ in Distinct Hematopoietic Cell Lineages

Further studies are needed to elucidate the cell type-specific regulatory mechanisms of YAP/TAZ in normal and malignant hematopoietic cells, and to determine the functional consequences of YAP/TAZ activation/inhibition in different subtypes of hematological malignancies. Single-cell transcriptomic studies have begun to resolve the expression patterns of Hippo pathway components in distinct hematopoietic lineages, revealing that YAP/TAZ activity is tightly regulated in a cell-context dependent manner. 5 This will provide a basis for the development of subtype-specific Hippo-targeted therapies. 18

Crosstalk Between the Hippo Pathway and the Tumor Microenvironment in Hematology

The bone marrow and lymph node microenvironments play a critical role in the progression and therapeutic resistance of hematological malignancies. Future studies should focus on the role of the Hippo pathway in regulating the interaction between malignant hematopoietic cells and stromal cells, immune cells, and endothelial cells in the tumor microenvironment, and explore the potential of targeting the Hippo pathway to remodel the tumor microenvironment. 14

Non-Coding RNA-Hippo Regulatory Networks

Non-coding RNAs (lncRNAs, miRNAs, circRNAs) are key regulators of the Hippo pathway in hematological malignancies. 62 Future research should identify novel non-coding RNA-Hippo axes in different hematological malignancies and explore their potential as diagnostic biomarkers and therapeutic targets. 62

Metabolic-Hippo Crosstalk in Hematological Malignancies

Hematological malignant cells rely on metabolic reprogramming for survival and proliferation, and the Hippo pathway is closely linked to metabolic pathways. 63 Future studies should elucidate the specific metabolic-Hippo regulatory mechanisms in hematological malignancies and develop dual-target therapies targeting metabolic pathways and the Hippo pathway. 39

Hippo Signaling and Transplantation-Associated Endothelial Injury

Recent studies suggest that Hippo signaling may play a role in endothelial dysfunction after allogeneic hematopoietic stem cell transplantation (allo-HSCT). 64 , 65 Because endothelial injury is a central feature of transplant-associated thrombotic microangiopathy (TA-TMA) and sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD), YAP/TAZ-mediated regulation of vascular homeostasis may represent a novel area of investigation. 65–67 Understanding this pathway could provide new biomarkers and therapeutic targets for transplant-related complications. 64 , 68 , 69

Technological Advances Driving Hippo Pathway Research in Hematology

Advanced molecular and computational technologies are providing new tools to study the Hippo pathway in hematological malignancies, deepening our understanding of its regulatory mechanisms and facilitating the development of novel therapeutic strategies.

CRISPR/Cas9 Gene Editing and in vivo Screening

CRISPR/Cas9 technology enables precise knockout/activation of Hippo pathway genes in hematopoietic cells and animal models, providing a powerful tool to study the functional role of the Hippo pathway in leukemogenesis and lymphomagenesis. 70 CRISPR-based screening in hematologic malignancies has identified novel Hippo-related vulnerabilities, such as the RHOBTB2-KLHL13 axis in AML, which could be exploited for therapeutic intervention. 30 In vivo CRISPR screening can identify novel Hippo-related vulnerabilities and synergistic drug targets in hematological malignancies, accelerating the development of combination therapies. 70

Single-Cell RNA Sequencing (scRNA-Seq)

scRNA-seq can resolve the transcriptomic heterogeneity of hematological malignancies at the single-cell level, revealing the expression pattern and activity of the Hippo pathway in distinct tumor cell subpopulations and immune cells. 71 This technology can identify rare malignant cell subpopulations with dysregulated Hippo pathway and provide a basis for precision targeting. 71

High-Resolution/Live-Cell Imaging

Live-cell and super-resolution microscopy can track the real-time subcellular localization of YAP/TAZ in hematological malignant cells and their dynamic changes in response to extracellular signals (eg., mechanical stress, cytokines). 72 This technology can elucidate the spatiotemporal regulation of the Hippo pathway in hematopoietic cells and identify the optimal timing for Hippo-targeted therapy. 72

Multi-Omics Integration and Bioinformatics Modeling

Integrating genomics, transcriptomics, proteomics, and metabolomics data can map the complex regulatory network of the Hippo pathway and its crosstalk with other signaling cascades in hematological malignancies. 73 Machine learning and computational modeling can predict the response to Hippo-targeted therapies and identify potential combination targets, facilitating the design of personalized treatment strategies 73 (Table 3).

Precision Medicine: The Core Direction of Hippo-Targeted Therapy in Hematology

The combination of the Hippo pathway and precision medicine is the key direction for the clinical translation of Hippo-targeted therapies in hematological malignancies. The development of precision medicine for Hippo-targeted therapy relies on three core pillars: validated clinical biomarkers, subtype-specific treatment strategies, and personalized combination therapies.

First, identifying and validating clinical biomarkers for Hippo pathway activity is critical for patient stratification. Potential biomarkers include: (i) expression levels of YAP/TAZ; (ii) genetic alterations in Hippo pathway components; and (iii) activity of Hippo pathway target genes. 14 These biomarkers should be validated in large clinical cohorts to determine their prognostic and predictive value. Liquid biopsy technologies (eg., circulating tumor DNA, exosomes) can be used to detect Hippo pathway alterations in real time, enabling dynamic monitoring of treatment response and early detection of resistance. 74

Second, subtype-specific treatment strategies are needed to address the functional heterogeneity of the Hippo pathway in different hematological malignancies. For example, YAP inhibition is a promising strategy for leukemia and DLBCL, while TAZ activation may be beneficial for MM. 18 Subtype-specific therapies should be developed based on the functional role of the Hippo pathway in each subtype, and multi-omics analysis can be used to guide the selection of appropriate therapeutic targets. 75

Third, personalized combination therapies should be designed based on the individual genetic and molecular profile of patients. For patients with concurrent activation of the Hippo and PI3K/Akt pathways, combination therapy with YAP and PI3K inhibitors is recommended. 28 For patients with dysregulated non-coding RNA-Hippo axes, non-coding RNA-based interventions combined with small-molecule inhibitors may be more effective. 62 Machine learning and bioinformatics can integrate multi-omics data to predict the optimal combination therapy for individual patients, maximizing the therapeutic effect and minimizing off-target effects. 73

In addition, the integration of artificial intelligence (AI) and big data into Hippo pathway research and clinical translation will further promote the development of precision medicine. AI can be used to analyze large-scale clinical and molecular data to identify novel Hippo-related biomarkers and therapeutic targets, and to design personalized treatment strategies. 76 Big data platforms can facilitate the sharing of clinical and molecular data from hematological malignancy patients, accelerating the validation of Hippo-targeted therapies and their clinical translation. 71

Conclusion

In conclusion, the Hippo signaling pathway has emerged as a critical regulatory network in both normal hematopoiesis and hematological malignancies. 18 Aberrant activation of its downstream effectors—YAP and TAZ—drives malignant proliferation, survival advantage, therapeutic resistance, and unfavorable clinical outcomes. 14 The context-dependent functional heterogeneity of YAP/TAZ in hematological malignancies—where they can act as either oncogenes or tumor suppressors depending on the specific lineage and microenvironment—underscores the necessity of precision medicine approaches in Hippo-targeted therapy. 5 , 25 , 77 Beyond its direct oncogenic effects, the extensive crosstalk between Hippo signaling and other pathways, including PI3K/AKT, TGF-β, Wnt/β-catenin, metabolic signaling, and non-coding RNA networks, further highlights its central role in hematologic tumor biology. 13

Recent advances in preclinical studies have demonstrated the therapeutic promise of targeting the Hippo pathway through YAP/TAZ inhibition, modulation of upstream regulators, and rational combination strategies with existing chemotherapeutic agents, targeted therapies, or immunotherapies. 5 Nevertheless, several challenges remain, including the context-dependent functional heterogeneity of YAP/TAZ, limited availability of highly specific inhibitors, compensatory activation of parallel oncogenic pathways, and the lack of clinically validated biomarkers for patient stratification. 13 , 14 , 59 , 78

With the rapid development of single-cell sequencing, CRISPR-based functional screening, multi-omics integration, and artificial intelligence-assisted biomarker discovery, a more comprehensive understanding of Hippo pathway dysregulation in hematological malignancies is becoming increasingly achievable. 70 Future efforts should focus on subtype-specific mechanisms, biomarker-guided patient selection, and personalized combination therapies to accelerate the clinical translation of Hippo-targeted strategies. 18 Overall, the Hippo pathway represents a highly promising avenue for precision medicine and may provide new therapeutic opportunities for patients with refractory hematological malignancies. 18

Despite substantial progress in understanding Hippo signaling biology, robust clinical evidence supporting Hippo-targeted therapies in hematological malignancies remains scarce. 46 , 79 , 80 Most available data are derived from preclinical studies, and only a limited number of Hippo-associated therapeutic strategies have entered early-phase clinical evaluation. 59 , 80 , 81 Future studies should prioritize validation of disease-specific mechanisms, development of predictive biomarkers, and well-designed clinical trials to establish the safety and efficacy of Hippo-targeted interventions in hematologic cancers. 29
