1442-长春花碱联合顺铂:通过自噬稳态重塑优化胃癌治疗收益

from 聊聊Sci

这篇文章探讨了如何通过联合用药来优化胃癌的化学治疗。研究发现,天然化合物长春质碱 (CA) 能够显著增强顺铂的抗肿瘤效果,并同时减轻其对肾脏和肝脏等器官的毒副作用。其核心机制在于对细胞自噬状态的精准重塑:在癌症细胞中,这种组合会引发破坏性自噬并导致细胞骨架崩解,从而诱导肿瘤凋亡。与此同时,在正常细胞中,它则激活了保护性自噬,有效修复药物带来的损伤并维持生理平衡。该研究利用患者来源的异种移植 (PDX) 等多种模型,证明了这种策略在克服铂类药物耐药性方面的巨大潜力。这种“减毒增效”的发现为临床开发低毒、高效的胃癌综合治疗方案提供了关键的理论依据。References:Pan G, Xu Q, Zhang K, et al.
