通过生物信息学方法鉴定PTPRR和JAG1为去势抵抗性前列腺癌(CRPC)的关键基因(英文)

发布时间:2021-09-02 21:15
  目的:鉴定去势抵抗性前列腺癌(CRPC)的关键基因。创新点:(1)结合多个数据库数据,运用生物信息学方法鉴定CRPC的关键基因;(2)首次报道PTPRR可能在CRPC里起关键作用。方法:通过下载三个GEO数据库的m RNA微阵列数据,分析CRPC和激素敏感前列腺癌之间的基因差异,对筛选出的差异基因进行功能富集分析和蛋白质间相互作用分析,最终筛选出两个有重要功能的差异基因(PTPRR和JAG1)。通过在多个其他数据库中进行表达量验证和生存分析,进一步证明这些基因的重要作用。结论:PTPRR和JAG1在CRPC中显著增高,并与预后差相关。因此,这两个基因有可能作为CRPC的诊断和预后的生物标志物。
