Cancer Resistance to Immunotherapy: Comprehensive Insights with Future Perspectives.

Cancer immunotherapy is a type of treatment that harnesses the power of the immune systems of patients to target cancer cells with better precision compared to traditional chemotherapy. Several lines of treatment have been approved by the US Food and Drug Administration (FDA) and have led to remarkable success in the treatment of solid tumors, such as melanoma and small-cell lung cancer. These immunotherapies include checkpoint inhibitors, cytokines, and vaccines, while the chimeric antigen receptor (CAR) T-cell treatment has shown better responses in hematological malignancies. Despite these

Combination Immunotherapy as a Promising Strategy to Overcome Immunotherapy Resistance: From Emergence to Next-Generation Approaches.

Advances in immunotherapy, particularly with immune checkpoint inhibitors, have improved clinical outcomes in various cancer subtypes; however, resistance often occurs because these treatments rely on single agents and show limited translational success when combined. Therefore, it is necessary to develop immune checkpoint inhibitor-based combination strategies by integrating next-generation immunotherapies and innovative biomarkers. This review highlights the emerging combinatorial approaches that can be tailored to the distinct tumor microenvironment types to overcome resistance to immune ch

miR-708-5p: a microRNA with emerging roles in cancer.

MicroRNAs (miRNAs) are small non-coding RNAs that negatively regulate gene expression post-transcriptionally. They are crucial for normal development and maintaining homeostasis. Researchers have discovered that dysregulated miRNA expression contributes to many pathological conditions, including cancer. miRNAs can augment or suppress tumorigenesis based on their expression and transcribed targetome in various cell types. In recent years, researchers have begun to identify miRNAs commonly dysregulated in cancer. One recently identified miRNA, miR-708-5p, has been shown to have profound roles in

Genus Sophora: a comprehensive review on secondary chemical metabolites and their biological aspects from past achievements to future perspectives.

Sophora is deemed as one of the most remarkable genera of Fabaceae, and the third largest family of flowering plants. The genus Sophora comprises approximately 52 species, 19 varieties, and 7 forms that are widely distributed in Asia and mildly in Africa. Sophora species are recognized to be substantial sources of broad spectrum biopertinent secondary metabolites namely flavonoids, isoflavonoids, chalcones, chromones, pterocarpans, coumarins, benzofuran derivatives, sterols, saponins (mainly triterpene glycosides), oligostilbenes, and mainly alkaloids. Meanwhile, extracts and isolated compoun

Tales from the Jazz ASH: highlights from the 2013 American Society of Haematology meeting.

The 55th annual ASH meeting was held in pleasant New Orleans and was the largest in its history, with 22,495 participants coming from 113 nations. A 'bench-to-bedside and back' attitude characterises haematology probably more than any other discipline in medicine and, as usual, this was reflected in the extremely wide breadth of the topics covered, including the last results from clinical trials and cutting-edge advancements in basic science. This year, the balance was arguably skewed: few truly clinical practice-changing results were presented. On the other hand, a great number of basic and t

Структура-ориентированное исследование ДНК-аптамера, целевого PTK7, выявляет сложную 3D-составляющую, направляющую оптимизацию функции.

DNA аптамеры вышли в качестве новых молекулярных инструментов в терапевтической и диагностической медицине благодаря своей высокой аффинности и специфичности к белковым целям, что определяется их способностью сворачиваться в отличительные трехмерные (3D) структуры. Однако при проектировании и моделировании аптамеров часто игнорируются тонкие атомные взаимодействия, формирующие 3D структуры, что приводит к неэффективной оптимизации функциональных свойств. Проблемы сохраняются при определении высокоразрешающих структур комплексов аптамер-белок. Кроме того, экспериментально определенные 3D структ

The role of B2M in cancer immunotherapy resistance: function, resistance mechanism, and reversal strategies.

Immunotherapy has emerged as a preeminent force in the domain of cancer therapeutics and achieved remarkable breakthroughs. Nevertheless, the high resistance has become the most substantial impediment restricting its clinical efficacy. Beta-2 microglobulin (B2M), the light chain of major histocompatibility complex (MHC) class I, plays an indispensable part by presenting tumor antigens to cytotoxic T lymphocytes (CTLs) for exerting anti-tumor effects. Accumulating evidence indicates that B2M mutation/defect is one of the key mechanisms underlying tumor immunotherapy resistance. Therefore, eluci

Targeting the p53 signaling pathway in cancers: Molecular mechanisms and clinical studies.

Tumor suppressor p53 can transcriptionally activate downstream genes in response to stress, and then regulate the cell cycle, DNA repair, metabolism, angiogenesis, apoptosis, and other biological responses. p53 has seven functional domains and 12 splice isoforms, and different domains and subtypes play different roles. The activation and inactivation of p53 are finely regulated and are associated with phosphorylation/acetylation modification and ubiquitination modification, respectively. Abnormal activation of p53 is closely related to the occurrence and development of cancer. While targeted t

CXCR4: A Promising Novel Strategy for Lung Cancer Treatment.

Lung cancer remains a major public health challenge due to high incidence and mortality. The chemokine receptor CXCR4 and its ligand CXCL12 (SDF-1) constitute a critical axis in tumor biology, influencing tumor cell proliferation, invasion, angiogenesis, and immune evasion. Aberrant CXCR4 expression is frequently observed in lung cancer and is closely associated with adverse prognosis, enhanced metastatic potential, and therapeutic resistance. Mechanistically, CXCR4 activates signaling pathways including PI3K/AKT, MAPK/ERK, JAK/STAT, and FAK/Src, promoting epithelial-mesenchymal transition, st

Current State of Knowledge on Primary Sjögren's Syndrome, an Autoimmune Exocrinopathy.

Primary Sjögren's syndrome (pSS) is a chronic systemic autoimmune rheumatic disease characterized by lymphoplasmacytic infiltration of the salivary and lacrimal glands, whereby sicca syndrome and/or systemic manifestations are the clinical hallmarks, associated with a particular autoantibody profile. pSS is the most frequent connective tissue disease after rheumatoid arthritis, affecting 0.3-3% of the population. Women are more prone to develop pSS than men, with a sex ratio of 9:1. Considered in the past as innocent collateral passive victims of autoimmunity, the epithelial cells of the saliv

SAE1 May Play a Pro-Carcinogenic Role in Pancreatic Adenocarcinoma: A Comprehensive Study Integrating Multiple Pieces of Evidence.

SAE1, a key factor in tumour development, has not been thoroughly examined in pancreatic adenocarcinoma (PAAD), a cancer with high incidence and poor prognosis. We conducted a comprehensive study, integrating mRNA data, immunohistochemistry, CRISPR-modified cell line analysis and single-cell RNA sequencing to assess SAE1's role in PAAD. We also used ChIP-Seq to explore SAE1's transcriptional regulation and analysed clinical data, drug sensitivity and molecular docking models. SAE1 mRNA was significantly overexpressed in PAAD, with a substantial impact on cell proliferation and migration. Funct

Decoding the molecular mechanisms of pyroptosis and its therapeutic development prospects.

Pyroptosis is an emerging form of inflammatory programmed cell death primarily mediated by the gasdermin protein family, characterized by cell swelling, membrane pore formation, and the release of pro-inflammatory cytokines such as IL-1β and IL-18. This mode of cell death has garnered significant attention due to its critical involvement in a variety of diseases, including cancer, cardiovascular disorders, autoimmune diseases, and metabolic syndromes, positioning it as a promising therapeutic target. Despite advances, the complexity of pyroptosis regulation and its dual roles in disease pathog

SFRP5 inhibits melanin synthesis of melanocytes in vitiligo by suppressing the Wnt/β-catenin signaling.

Secreted frizzled-related protein 5 (SFRP5) plays a pivotal role in regulating the development of many tissues and organs, however, as an inhibitor of Wnt signaling, the role of SFRP5 in vitiligo remains unknown. Hence, we speculated that SFRP5 might be associated with melanogenesis in melanocytes by regulating Wnt signaling in vitiligo. In this study, we found that SFRP5 was overexpressed in the skin lesions of patients with vitiligo. Compared with that in normal epidermal melanocytes (PIG1), the expression of SFRP5 was increased in vitiligo melanocytes (PIG3V). To investigate the effect of S

The crosstalk network of non-coding RNAs: Emerging opportunities for the clinical application of osteoporosis.

Current methods for testing bone density lack the capability to detect patients with early bone loss, and existing osteoporosis therapies have limitations in their efficacy and safety. Therefore, the development of more precise and convenient diagnostic technologies and novel treatments is of paramount importance. Extracellular vesicle (EV)-mediated non-coding RNA (ncRNA) interaction networks enable both the detection of early bone loss and targeted therapy for enhanced treatment outcomes. In this review, we highlight the utility of EVs for carrying various ncRNAs (e.g., miRNAs, lncRNAs, and c

Gene expression-based prediction of myeloma cell sensitivity to histone deacetylase inhibitors.

BACKGROUND: Multiple myeloma (MM) is still a fatal plasma cell cancer. Novel compounds are currently clinically tested as a single agent in relapsing patients, but in best cases with partial response of a fraction of patients, emphasising the need to design tools predicting drug efficacy. Histone deacetylase inhibitors (HDACi) are anticancer agents targeting epigenetic regulation of gene expression and are in clinical development in MM. METHODS: To create a score predicting HDACi efficacy, five MM cell lines were treated with trichostatin A (TSA) and gene expression profiles were determined.

Liquid biopsies in myeloid malignancies.

Hematologic malignancies are the most common type of cancer affecting children and young adults, and encompass diseases, such as leukemia, lymphoma, and myeloma, all of which impact blood associated tissues such as the bone marrow, lymphatic system, and blood cells. Clinical diagnostics of these malignancies relies heavily on the use of bone marrow samples, which is painful, debilitating, and not free from risks for leukemia patients. Liquid biopsies are based on minimally invasive assessment of markers in the blood (and other fluids) and have the potential to improve the efficacy of diagnosti

IKZF3 is a novel prognostic biomarker for head and neck squamous cell carcinoma: A study based on bioinformatics analysis.

In the past few years, immunotherapy of tumors has become an extensive research hotspot, and the value of IKZF family genes in the tumor microenvironment has also been increasingly recognized. However, the expression of the IKAROS family zinc finger 3 (IKZF3) gene in human head and neck squamous cell carcinoma (HNSCC) and its prognostic value were not reported for the main subset until now. In the present study, we analyzed the relationship between IKZF3 gene expression and the survival of HNSCC patients. To evaluate the potential of IKZF3 as a prognostic biomarker for HNSCC comprehensively, m

Targeting translation initiation in breast cancer.

Over the past 20 years, a better understanding of cancer biology, screening for early detection, improved adjuvant treatment, and targeted therapies have decreased the rate of breast cancer deaths. However, resistance to treatment is common, and new approaches are needed. Deregulation of translation initiation is associated with the commencement and progression of cancer. Often, translation initiation factors are overexpressed and the related signaling pathways activated in human tumors. Recently, a significant number of inhibitors that target translation factors and pathways have become avail
