1457-MRPL3驱动肝细胞癌早期复发的线粒体调控机制

from 聊聊Sci

这份研究探讨了线粒体核糖体蛋白L3(MRPL3)在肝细胞癌(HCC)术后早期复发中的关键作用及其分子机制。研究通过蛋白组学分析发现,MRPL3在肝癌组织中显著高表达,且其水平与患者的微血管侵犯及较差的生存预后密切相关。实验证明,MRPL3能通过增强线粒体呼吸功能、提升膜电位并减少活性氧,从而显著促进癌细胞的增殖、迁移与侵袭。从机制上看,MRPL3与线粒体外膜蛋白TOMM40结合并使其稳定,进而激活PGC-1α/TFAM信号通路,驱动线粒体生物发生。研究结果表明,MRPL3不仅是预测肝癌复发的生物标志物,更是阻断代谢重塑和抑制肿瘤进展的潜在治疗靶点。References:Wang S, Yang W, Pan T, et al.
