Apoptosis, as a very important biological process, is response to developmental cues or cellular stress. Impaired apoptosis plays central role in the development of cancer and also reduces efficacy traditional cytotoxic therapies. Members B-cell lymphoma 2 (BCL-2) protein family have pro- anti-apoptotic activities been studied intensively over past decade for their importance regulating apoptosis, tumorigenesis, responses anticancer therapy. Since inflammatory induced by apoptosis-induced cell death small, at present, drugs targeting has attracted more attention. Consequently, focus this review summarize current research on BCL-2 proteins proteins. Additionally, mechanism was explored. All findings indicate potential therapy cancer.

Frontiers in Pharmacology, Год журнала: 2023, Номер 14

Опубликована: Ноя. 6, 2023

Abnormal cellular apoptosis plays a pivotal role in the pathogenesis of Multiple Myeloma (MM). Over years, BCL-2, crucial anti-apoptotic protein, has garnered significant attention MM therapeutic research. Venetoclax (VTC), small-molecule targeted agent, effectively inhibits promoting programmed death cancerous cells. While VTC been employed to treat various hematological malignancies, its particular efficacy showcased potential for broader clinical applications. In this review, we delve into intricacies how modulates cells by targeting BCL-2 and overarching influence protein family regulation. Our findings highlight nuanced interplay between VTC, MM, offering insights that may pave way optimizing strategies. Through comprehensive analysis, aim lay solid groundwork future explorations VTC’s applications profound effects on apoptosis.

Epigallocatechin gallate modulates ferroptosis through downregulation of tsRNA-13502 in non-small cell lung cancer

Cancer Cell International, Год журнала: 2024, Номер 24(1)

Опубликована: Июнь 5, 2024

Abstract Ferroptosis, an iron-dependent regulated cell death mechanism, holds significant promise as a therapeutic strategy in oncology. In the current study, we explored regulatory effects of epigallocatechin gallate (EGCG), prominent polyphenol green tea, on ferroptosis and its potential implications for non-small lung cancer (NSCLC). Treatment NSCLC lines with varying concentrations EGCG resulted notable suppression proliferation, evidenced by reduction Ki67 immunofluorescence staining. Western blot analyses demonstrated that treatment led to decrease expression glutathione peroxidase 4 (GPX4) solute carrier family 7 member 11 (SLC7A11) while increasing levels acyl-CoA synthetase long-chain (ACSL4). These molecular changes were accompanied increase intracellular iron, malondialdehyde (MDA), reactive oxygen species (ROS), alongside ultrastructural alterations characteristic ferroptosis. Through small RNA sequencing RT-qPCR, transfer RNA-derived 13502 (tsRNA-13502) was identified target action, being upregulated tissues compared adjacent non-tumorous tissues. found modulate pathway downregulating tsRNA-13502 altering key regulators (GPX4/SLC7A11 ACSL4), thereby promoting accumulation MDA, ROS, ultimately inducing cells. This study elucidates EGCG’s multifaceted mechanisms underscoring modulation viable approach enhancing outcomes.
