Abstract Metabolic reprogramming involving branched-chain amino acids (BCAAs)—leucine, isoleucine, and valine—is increasingly recognized as pivotal in cancer progression, metastasis, and immune modulation. This review comprehensively explores how cancer cells rewire BCAA metabolism to enhance proliferation, survival, and therapy resistance. Tumors manipulate BCAA uptake and catabolism via high expression of transporters like L-type amino acid transporter 1 (LAT1) and enzymes including branched chain amino acid transaminase 1(BCAT1), branched chain amino acid transaminase 2 (BCAT2), branched-chain alpha-keto acid dehydrogenase (BCKDH), and branched chain alpha-keto acid dehydrogenase kinase (BCKDK). These alterations sustain energy production, biosynthesis, redox homeostasis, and oncogenic… More >

Abstract Male breast cancer (MBC) is rare, representing 0.5%–1% of all breast cancers, but its incidence is increasing due to improved diagnostics and awareness. MBC typically presents in older men, is human epidermal growth factor receptor 2 (HER2)-negative and estrogen receptor (ER)-positive, and lacks routine screening, leading to delayed diagnosis and advanced disease. Major risk factors include hormonal imbalance, radiation exposure, obesity, alcohol use, and Breast Cancer Gene 1 and 2 (BRCA1/2) mutations. Clinically, it may resemble gynecomastia but usually appears as a unilateral, painless mass or nipple discharge. Advances in imaging and liquid biopsy have More >

Abstract Cholangiocarcinoma (CCA) is an aggressive cancer originating from bile duct epithelium. Surgical resection remains the primary curative treatment for CCA. However, most CCA patients are diagnosed at an advanced stage, which limits the applicability of surgical resection. Gemcitabine is widely used as a first-line chemotherapeutic agent for unresectable CCA. Its efficacy is often compromised by the development of drug resistance, which leads to poor clinical outcomes and low survival rates of CCA patients. At present, the mechanisms underlying gemcitabine resistance in CCA remain unclear. This review aimed to comprehensively summarize the current knowledge on the More >

Abstract Diabetic foot ulcers (DFUs) are a serious complication of diabetes mellitus and are associated with high morbidity, risk of amputation, and increased mortality. Although DFUs typically remain a chronic, non-healing wound, a small portion of DFUs may undergo malignant transformation. The subsequent malignancies are skin cancers such as squamous cell carcinoma (SCC), basal cell carcinoma, or melanoma. Understanding the pathophysiology of DFUs and the molecular and clinical determinants that contribute to their potential malignant transformation if crucial for clinical management. Chronic inflammation, dysregulation of cytokine signaling, faulty immune surveillance, and impaired wound healing all play… More >

Abstract The ability of plants to tolerate cold is a complex process. When temperatures drop or freeze, plant tissues can develop ice, which dehydrates the cells. However, plants can protect themselves by preventing ice formation. This intricate response to cold stress is regulated by hormones, photoperiod, light, and various factors, in addition to genetic influences. In autumn, plants undergo morphological, physiological, biochemical, and molecular changes to prepare for the low temperatures of winter. Understanding cellular stress responses is crucial for genetic manipulation aimed at enhancing cold resistance. Early autumn frosts or late spring chills can cause… More >

Abstract Congenital heart disease (CHD) is the most common birth defect, with 34% of cases attributed to genetic variants. NOTCH1, a multi-domain transmembrane protein, regulates heart development by controlling the differentiation and migration of myocardial mesoderm cells, and different variants are present in different types of CHD. In this review, we aim to provide a detailed description of NOTCH1 structural domains and their functions, highlighting NOTCH1 variants in CHD and the molecular mechanisms through which they contribute to CHD occurrence. NOTCH1 has two main domains, the NOTCH extracellular domain (NECD) and the NOTCH intracellular domain… More >

Abstract Nitrogen (N) assimilation is crucial for the growth and development of C₃ plants, as it converts inorganic N into organic forms, important for protein synthesis, nucleic acids and other vital biomolecules. However, abiotic stressors such as drought, salinity, extreme temperatures and others significantly impact N uptake and utilization, thereby hindering plant growth and development. Recent advances in molecular biology have illuminated the complex networks that govern N assimilation under these stressful conditions, emphasizing the role of transcription factors, regulatory genes, and stress-responsive pathways. This review provides an integrated perspective on the latest research in nitrogen metabolism… More >

Abstract Nucleosomes play a vital role in chromatin organization and gene regulation, acting as key hubs that interact with various chromatin-associated factors through diverse binding mechanisms. Recent research has highlighted the prevalence of mutations in linker histones across different types of cancer, emphasizing their critical involvement in cancer progression. These cancer-associated mutations in linker histones have been shown to disrupt nucleosome stacking and the formation of higher-order chromatin structures, which in turn significantly affect epigenetic regulatory processes. In this review, we provide a comprehensive analysis of how cancer-associated linker histone mutations alter their physicochemical properties, influencing More >

Abstract Circular RNAs (circRNAs) are formed by splicing of precursor RNAs and covalently linked at the 5′ and 3′ ends. Dysregulated circRNAs are closely related to the epithelial-mesenchymal transition (EMT) of gastrointestinal malignancies. CircRNAs, including circRNA_0008717, circGOT1, circ-DOCK5, circVPS33B, circPVT1, circMET, circ-OXCT1, circ_67835, circRTN4, circ_0087502, circFNDC38, circ_PTEN1, circPGPEP1, and circ-E-Cad are involved in the EMT process of gastrointestinal malignancies through a variety of mechanisms, such as regulating EMT-inducing transcription factors, signaling pathways, and tumor microenvironments. Gastrointestinal (GI) malignancies are common malignant tumors worldwide, and the heterogeneity and easy metastasis of gastrointestinal malignancies limit the effectiveness of More > Graphic Abstract

Abstract Hepatitis B-associated hepatocellular carcinoma (HBV-HCC) remains an intractable high-mortality solid tumor cancer that accounted for 42% of global HCC cases in 2019. Despite some developments in systemic therapy, only a small subset of late-stage HCC patients responds positively to recently developed therapeutic innovations. MicroRNAs (miRNAs) act as an ancillary epigenetic system that can regulate genome expression in all cancer pathways including HCC. The molecular mechanisms of miRNA regulation in cancer pathogenesis offered researchers a new approach that was widely hoped would translate into miRNA-based drugs and diagnostics. Thirty years on, miRNA-based diagnostic and therapeutic agents… More >
