摘要
肝细胞癌(HCC)是全球第六大诊断的预后不良的癌症。虽然肝细胞癌的病理因素已被很好地阐明,但其潜在的分子机制尚不清楚。N6-甲基腺苷(M6A)是发生在N6位点的腺苷甲基化,这是真核mRNA最常见的修饰。近年来的研究表明,M6A可以调控基因表达,从而调控细胞的自我更新、分化和凋亡过程。M6A中的甲基由甲基转移酶(“著者”)安装,由去甲基酶(“橡皮擦”)去除,并被M6A结合蛋白(“读卡器”)识别。本文就上述调控因子在HCC进展和预后中的作用进行探讨,并总结M6A修饰与肝细胞癌的临床联系,以期为临床治疗提供更有价值的信息。
关键词: 肝细胞癌,n6 -甲基腺苷,RNA甲基化,甲基转移酶,去甲基酶,m6a结合蛋白。
