This phenomenon is orchestrated through a confluence of processes, which we propose as the major hallmarks of chemoresistance in cancer. Dysregulation of drug transporters, activation of pro-survival pathways, cancer stem cell driven proliferation, DNA damage and repair mechanisms, evasion of apoptosis, autophagy induction, secretion of extracellular vesicles, and metabolic reprogramming represents the major mechanisms of chemoresistance in cancer. Breast cancer is one of the most common and aggressive types of cancer, with significant challenges in treatment due to its heterogeneity. Despite progress in various treatment regimens, chemoresistance continues to be a significant challenge in the effective management of breast cancer. In this context, high-throughput proteomic methodologies, which quantitatively assess proteome-wide alterations and explore post-translational modifications, can provide an unbiased framework for unraveling the molecular intricacies of chemotherapy resistance. This article comprehensively reviews the application of advanced proteomic techniques in elucidating the pathophysiological mechanisms of chemoresistance in breast carcer. Additionally, it highlights promising protein signatures uncovered via proteomic tools, as well as therapeutic strategies targeting chemoresistant hallmarks to overcome drug resistance in breast cancer. By leveraging proteomic technologies, we move closer to more effective and personalized therapeutic interventions for chemoresistant breast cancer.</p>","PeriodicalId":93897,"journal":{"name":"Biochimica et biophysica acta.

Recent insights into the tumor microenvironment (TME) have highlighted the pivotal role of amino acid metabolism-one of the three core metabolic pathways-in driving tumor proliferation, metastasis, and resistance to therapy. Taurine, a conditionally essential amino acid abundantly present in various tissues, does not participate in protein synthesis but exhibits multiple biological functions, including antioxidant, anti-inflammatory, and cytoprotective effects. These properties are increasingly recognized as relevant in both physiological regulation and pathological conditions such as cancer. Emerging evidence suggests that taurine modulates tumor growth and progression through diverse mechanisms, including regulation of immune responses, redox homeostasis, cellular metabolism, and the TME. This review summarizes the multifaceted roles of taurine in tumorigenesis and its potential applications in cancer therapy, providing new perspectives for targeted intervention.</p>","PeriodicalId":93897,"journal":{"name":"Biochimica et biophysica acta.

Anoikis, a form of programmed cell death triggered by cell detachment from the extracellular matrix (ECM), and NETosis, a neutrophil cell death mode releasing extracellular traps (NETs), play critical roles in CRC liver metastasis (CRCLM). This review explores the mechanisms of anoikis and NETosis, their interplay, and genetic underpinnings in CRCLM. Anoikis resistance in CRC cells allows survival during metastasis in the initial stage, while NETs promote tumor progression by facilitating immune evasion, ECM remodeling, and angiogenesis. Meanwhile, through bioinformatics analysis and summary, we elaborated on the relationship between anoikis and NETosis as well as the potential interaction mechanisms, exploring the connecting links between them. The crosstalk between these processes is analyzed, highlighting shared signaling pathways (e.g., PI3K/AKT, MAPK, EMT) and potential biomarkers (e.g., MUC13, GLI2, SIRT6, FASN). Therapeutic strategies targeting anoikis and NETosis, including inhibitors of integrins, EGFR, and NET components (e.g., DNase I, CXCR2 antagonists), inhibitors of autophagy (e.g., CQ, HCQ, azithromycin) are discussed. This comprehensive analysis advances understanding of CRCLM pathogenesis and provides novel perspectives for targeted interventions.</p>","PeriodicalId":93897,"journal":{"name":"Biochimica et biophysica acta.

These molecular patterns profoundly interfere with the elements of cellular proteostasis systems that support the efficiency of the recurrence process. As a major proteostasis machinery, we review the role of the ubiquitin-proteasome system (UPS) in tumor cell dormancy and reawakening, devoting particular attention to the functions of its components, E3 ligases, deubiquitinating enzymes and proteasomes in cancer recurrence. We demonstrate how UPS components functionally or mechanistically interact with the pivotal proteins implicated in the recurrence program and reveal that modulators of the UPS hold promise to become an efficient adjuvant therapy for eradicating refractory tumor cells to impede tumor relapse.</p>","PeriodicalId":93897,"journal":{"name":"Biochimica et biophysica acta.
