786-肝癌早期恶性转化分子机制研究

from 聊聊Sci

这项研究通过分析罕见的“结节中结节”样本,深入揭示了肝细胞癌(HCC)从癌前病变向早期恶性转化的分子机制。研究人员发现,TERT基因改变虽普遍存在于癌前不良增生结节中,但仅起到预警作用,而染色体拷贝数变异(CNA)的积累才是驱动恶性转化的关键因素。实验证明,ECHS1和FGA等基因的缺失会显著促进肝脏类器官的生长与病变。在免疫环境方面,癌前结节通常表现为“免疫沙漠”表型,而约43%的早期肝癌则表现出炎症激活与免疫逃逸并存的特征。基于这些发现,研究提出了CNA主导型和炎症免疫逃逸型两种主要的肝癌演化路径。这一成果不仅完善了肝癌早期演化的理论,也为通过免疫治疗**进行早期干预提供了科学依据。References: Zhang Z, Li H, Chen L, et al.
