NF-κB in biology and targeted therapy: new insights and translational implications.

NF-κB signaling has been discovered for nearly 40 years. Initially, NF-κB signaling was identified as a pivotal pathway in mediating inflammatory responses. However, with extensive and in-depth investigations, researchers have discovered that its role can be expanded to a variety of signaling mechanisms, biological processes, human diseases, and treatment options. In this review, we first scrutinize the research process of NF-κB signaling, and summarize the composition, activation, and regulatory mechanism of NF-κB signaling. We investigate the interaction of NF-κB signaling with other importa

Immune evasion in cancer: mechanisms and cutting-edge therapeutic approaches.

Immune evasion represents a significant challenge in oncology. It allows tumors to evade immune surveillance and destruction, thereby complicating therapeutic interventions and contributing to suboptimal patient outcomes. This review addresses the critical need to understand how cancers evade immune surveillance. It aims to provide a comprehensive overview of strategies of tumors to escape immune detection by examining tumor-induced immune suppression, immune checkpoint regulation, and genetic and epigenetic influences. Moreover, it explores the dynamic role of the tumor microenvironment (TME)

By organizing these compounds into chemical families, we provide a structured overview of their po

Cancer stem cells in esophageal squamous cell cancer.

Cancer stem cells (CSCs) are hypothesized to govern the origin, progression, drug resistance, recurrence and metastasis of human cancer. CSCs have been identified in nearly all types of human cancer, including esophageal squamous cell cancer (ESCC). Four major methods are typically used to isolate or enrich CSCs, including: i) fluorescence-activated cell sorting or magnetic-activated cell sorting using cell-specific surface markers; ii) stem cell markers, including aldehyde dehydrogenase 1 family member A1; iii) side population cell phenotype markers; and iv) microsphere culture methods. ESCC

The Clinical Impact of Death Domain-Associated Protein and Holliday Junction Recognition Protein Expression in Cancer: Unmasking the Driving Forces of Neoplasia.

Death domain-associated protein (DAXX) and Holliday junction recognition protein (HJURP) act as chaperones of H3 histone variants H3.3 and centromere protein A (CENPA), respectively, and are implicated in many physiological processes, including aging and epigenetic regulation, by controlling various genes' transcription and subsequently protein expression. Research has highlighted both these biomolecules as participants in key procedures of tumorigenesis, including cell proliferation, chromosome instability, and oncogene expression. As cancer continues to exert a heavy impact on patients' well

Peroxisome Proliferator-Activated Receptors (PPAR)γ Agonists as Master Modulators of Tumor Tissue.

In most clinical trials, thiazolidinediones do not show any relevant anti-cancer activity when used as mono-therapy. Clinical inefficacy contrasts ambiguous pre-clinical data either favoring anti-tumor activity or tumor promotion. However, if thiazolidinediones are combined with additional regulatory active drugs, so-called 'master modulators' of tumors, i.e., transcriptional modulators, metronomic low-dose chemotherapy, epigenetically modifying agents, protein binding pro-anakoinotic drugs, such as COX-2 inhibitors, IMiDs, etc., the results indicate clinically relevant communicative reprogram

Noncanonical SQSTM1/p62-Nrf2 pathway activation mediates proteasome inhibitor resistance in multiple myeloma cells via redox, metabolic and translational reprogramming.

Multiple Myeloma (MM) is a B-cell malignancy characterized by the accumulation of clonal plasma cells in the bone marrow, with drug resistance being a major cause of therapeutic failure. We established a carfilzomib-resistant derivative of the LP-1 MM cell line (LP-1/Cfz) and found that the transcription factor NF-E2 p45-related factor 2 (Nrf2; gene symbol NFE2L2) contributes to carfilzomib resistance. The mechanism of Nrf2 activation involved enhanced translation of Nrf2 as well as its positive regulator, the autophagy receptor sequestosome 1 (SQSTM1)/p62. The eukaryotic translation initiatio

Epigallocatechin-3-Gallate Therapeutic Potential in Cancer: Mechanism of Action and Clinical Implications.

Cellular signaling pathways involved in the maintenance of the equilibrium between cell proliferation and apoptosis have emerged as rational targets that can be exploited in the prevention and treatment of cancer. Epigallocatechin-3-gallate (EGCG) is the most abundant phenolic compound found in green tea. It has been shown to regulate multiple crucial cellular signaling pathways, including those mediated by EGFR, JAK-STAT, MAPKs, NF-κB, PI3K-AKT-mTOR, and others. Deregulation of the abovementioned pathways is involved in the pathophysiology of cancer. It has been demonstrated that EGCG may exe

Decoding the epitranscriptome: a new frontier for cancer therapy and drug resistance.

As the role of RNA modification in gene expression regulation and human diseases, the "epitranscriptome" has been shown to be an important player in regulating many physiological and pathological processes. Meanwhile, the phenomenon of cancer drug resistance is becoming more and more frequent, especially in the case of cancer chemotherapy resistance. In recent years, research on relationship between post-transcriptional modification and cancer including drug resistance has become a hot topic, especially the methylation of the sixth nitrogen site of RNA adenosine-m6A (N6-methyladenosine). m6A m

Oleocanthal as a Multifunctional Anti-Cancer Agent: Mechanistic Insights, Advanced Delivery Strategies, and Synergies for Precision Oncology.

Oleocanthal (OC), a secoiridoid phenolic compound exclusive to extra virgin olive oil (EVOO), has emerged as a promising nutraceutical with multifaceted anti-cancer properties. Despite its well-characterized anti-inflammatory and antioxidant effects, the mechanistic breadth and translational potential of OC in oncology remain underexplored and fragmented across the literature. This comprehensive review synthesizes and critically analyzes recent advances in the molecular, pharmacological, and translational landscape of OC's anti-cancer activities, providing an integrative framework to bridge pr

Novel therapeutic strategies targeting resistance mechanisms in hematologic malignancies: from BCL2 inhibition to immunomodulatory approaches.

BACKGROUND: Hematologic malignancies, including chronic lymphocytic leukemia (CLL), acute myeloid leukemia (AML), non-Hodgkin lymphoma (NHL), and multiple myeloma (MM), are characterized by high relapse rates due to intrinsic and acquired drug resistance. Resistance mechanisms often involve dysregulation of apoptosis pathways, such as B-cell lymphoma 2 (BCL2) family overexpression, and immune evasion through microenvironment modulation. PURPOSE: This review synthesizes recent advances (2020-2025) in therapeutic strategies targeting these mechanisms, focusing on BCL2 inhibition and immunomodul

Chemotherapy-Mediated Complications of Wound Healing: An Understudied Side Effect.

Significance: Chemotherapy is a primary method to treat cancer. While chemotherapeutic drugs are designed to target rapidly dividing cancer cells, they can also affect other cell types. In the case of dermal cells and macrophages involved in wound healing, cytotoxicity often leads to the development of chronic wounds. The situation becomes even more severe when chemotherapy is combined with surgical tumor excision. Recent Advances: Despite its significant impact on patients' recovery from surgery, the issue of delayed wound healing in individuals undergoing chemotherapy remains inadequately ex

High-dose vitamin C: A promising anti-tumor agent, insight from mechanisms, clinical research, and challenges.

Vitamin C, also known as ascorbic acid, has sparked controversy since it first emerged as a potential anti-cancer agent. However, an increasing number of preclinical studies have demonstrated that high-dose vitamin C exhibits selective anti-tumor effects, including "pro-oxidative cytotoxicity", "anti-cancer epigenetic regulation", and "immune modulation". Consequently, vitamin C has reemerged as a promising anti-cancer therapy in the form of high-dose administration. Advancements in pharmacokinetic research have facilitated the development of clinical trials. Early clinical studies across vari

CAR T-cell therapy in autoimmune diseases: a promising frontier on the horizon.

Although current treatments for autoimmune diseases can effectively control symptoms, they rarely lead to cures and often require lifelong use, accompanied by considerable adverse effects. This emphasizes the urgent need for more targeted therapies that offer long-term efficacy and curative potential. Chimeric antigen receptor (CAR) T-cell therapy presents a promising option by specifically targeting and eliminating autoreactive B cells, with the potential to reset the patient's immune system and promote long-term immune balance. Originally developed for treating hematologic malignancies, wher

From Bench to Bedside and Beyond: Therapeutic Scenario in Acute Myeloid Leukemia.

Acute myeloid leukemia (AML) is a heterogeneous group of clonal disorders characterized by abnormal proliferation of undifferentiated myeloid progenitors, impaired hematopoiesis, and variable response to therapy. To date, only about 30% of adult patients with AML become long-term survivors and relapse and/or disease refractoriness are the major cause of treatment failure. Thus, this is an urgent unmet clinical need and new drugs are envisaged in order to ameliorate disease survival outcomes. Here, we review the latest therapeutic approaches (investigational and approved agents) for AML treatme

Cell-based immunotherapy of glioblastoma multiforme.

Glioblastoma multiforme (GBM) is the most aggressive and lethal primary glial brain tumor. It has an unfavorable prognosis and relatively ineffective treatment protocols, with the median survival of patients being ~15 months. Tumor resistance to treatment is associated with its cancer stem cells (CSCs). At present, there is no medication or technologies that have the ability to completely eradicate CSCs, and immunotherapy (IT) is only able to prolong the patient's life. The present review aimed to investigate systemic solutions for issues associated with immunosuppression, such as ineffective
