1266-CBX2相分离驱动脂质筏重塑促进卵巢癌转移

from 聊聊Sci

这项研究揭示了CBX2蛋白在促进卵巢癌大肠膜转移中的核心作用及其分子机制。研究发现,CBX2通过液-液相分离(LLPS)过程,在转录层面调控关键蛋白FLOT1的表达,进而重塑细胞表面的脂质筏结构。这种重塑过程不仅加速了具有促转移能力的细胞外囊泡(EVs)的生成,还优化了其内部促癌物质的装载。实验证据表明,阻断CBX2的相分离能力或破坏脂质筏的稳定性,能显著抑制肿瘤细胞的扩散。因此,CBX2被确定为卵巢癌恶性进展的重要驱动因子,并有望成为临床上抑制肿瘤转移的潜在治疗靶点。References:Wu, Q., Xu, X., Liu, X. et al.
