Emerging evidence indicates that alcohol intake is associated with human cancers in different organs. However, the molecular mechanism of alcohol-associated human cancers remains to be elucidated. Here, this paper aimed to clarify a novel mechanism of alcohol-promoted cell transformation and tumor development. Alcohol induces JNK1 activation and increases cellular levels of c-Jun to upregulate Brf1 expression and Pol III gene transcription, leading to an enhancement of rates of cell transformation and tumor formation.
新出现的证据表明,饮酒与人体不同器官的癌症有关。然而,酒精相关人类癌症的分子机制仍有待阐明。在此,本文旨在阐明酒精促进细胞转化和肿瘤发展的新机制。酒精诱导JNK1激活并增加c-Jun的细胞水平,以上调Brf1表达和Pol III基因转录,从而提高细胞转化和肿瘤形成的速率。
