831-卵巢癌空间肿瘤进化全景图

from 聊聊Sci

这篇研究利用多组学技术整合了全基因组测序、单细胞测序和空间转录组学,揭示了高致死性卵巢癌的时空演化全景。研究团队开发了STARLETS系统,发现在原发灶中,缺氧压力和免疫监视共同驱动了肿瘤克隆的达尔文式进化与选择。通过高分辨率成像,科学家们首次在腹水和转移灶中发现了一种由SPP1+巨噬细胞、MMP11+成纤维细胞与恶性肿瘤细胞构成的三元结构(tripartite ensemble)。该研究证实,通过药物靶向SPP1-CD44轴能够有效阻断肿瘤的腹膜播散,为治疗转移性卵巢癌提供了新靶点。此外,SPP1+巨噬细胞的丰度被证明可以作为预测溶瘤病毒和PARP抑制剂临床疗效的关键指标。这项工作不仅深化了对卵巢癌转移机制的理解,还为精准治疗策略的制定提供了重要的分子依据。References: Feng C, Yang Y, Li G, et al.
