胃的体细胞突变
体细胞突变在正常组织中普遍存在,这是公认的事实。不太清楚的是,这些突变是如何引发癌症等疾病的。Coorens等人在胃中解决了这个问题。研究小组分析了来自30名参与者的238个胃腺的全基因组数据,其中18人患有胃癌。此外,他们从829个显微解剖中获得了靶向测序数据。在正常腺体中操作的突变过程导致每年大约28个突变的累积。但是,随着腺体从正常发展为癌症,与复制、炎症和氧化损伤相关的新过程出现,增加了突变负担。典型的胃癌相关突变如TP53和PIK3CA在正常腺体中不存在,取而代之的是ARID1A、ARID1B、ARID2和KDM6A的突变。这些在慢性炎症的腺体中富集,并显示出与年龄相关的患病率增加。这些分析表明,胃癌的路径是由细胞内在或外在突变过程之间精心编排的相互作用铺就的——每一个突变过程都赋予细胞新的或增强的能力。下一步将是确定这些突变如何影响细胞功能,以及这种理解是否可以用于预防、检测或治疗这种疾病。原始参考文献:Nature https://doi.org/10.1038/s41586-025-08708-6 (2025)

期刊介绍: Nature Genetics publishes the very highest quality research in genetics. It encompasses genetic and functional genomic studies on human and plant traits and on other model organisms. Current emphasis is on the genetic basis for common and complex diseases and on the functional mechanism, architecture and evolution of gene networks, studied by experimental perturbation. Integrative genetic topics comprise, but are not limited to: -Genes in the pathology of human disease -Molecular analysis of simple and complex genetic traits -Cancer genetics -Agricultural genomics -Developmental genetics -Regulatory variation in gene expression -Strategies and technologies for extracting function from genomic data -Pharmacological genomics -Genome evolution
