1258-胃窦肠化生与早期肠型胃癌的单细胞分层研究

from 聊聊Sci

这项研究通过单细胞RNA测序和空间转录组学技术,系统地解析了胃腺癌(IGC)在不同病理阶段的细胞分化轨迹。研究人员发现,祖细胞(PCs)在疾病早期驱动黏液细胞的分化,但在肠上皮化生阶段,祖细胞与腺体黏液细胞均能转化为肠样干细胞并最终发育为肠上皮细胞。在胃癌早期阶段,研究确定了KIAA0101+PRAP1+祖细胞可能是胃癌细胞的演化起源。此外,HNF4A、ESRRA和SIRT6等关键转录因子被证实是调控这些谱系转换的核心分子。这些发现为胃癌的早期诊断、预防及精准治疗提供了全新的分子生物学证据和潜在靶点。研究构建了一个基于疾病阶段的胃黏膜重塑框架,深化了对胃癌发生过程中细胞可塑性的理解。References:Yin H, Zhang H, Zheng S, et al.
