1455-宫颈鳞癌演进的多组学时空图谱与驱动因子

from 聊聊Sci

这项研究利用单细胞转录组测序和空间转录组技术,系统地绘制了人类宫颈癌前病变至鳞状细胞癌演变过程中的分子和细胞图谱。通过对同一患者不同病理阶段组织的动态对比,研究者发现成纤维细胞、内皮细胞和B细胞亚群在恶变过程中发生了显著的免疫抑制性改变。实验证实,CLDN1、ISG15和PTGDS这三种基因可作为疾病进展的关键生物标志物,其中ISG15通过稳定FGF1蛋白激活PI3K/AKT/mTOR信号通路,进而驱动肿瘤生长。此外,研究强调了FGFR1抑制剂及PI3K/AKT通路阻断剂在临床治疗中具有重要的应用潜力。这些发现不仅揭示了宫颈癌演化的生态位特征,也为早期诊断和精准靶向治疗提供了科学依据。References:Zhou Y, Luo Y, Ge Y, et al.
