昼夜节律紊乱是现代社会的一个显着特征,已被世界卫生组织指定为可能的致癌物。然而,将昼夜节律破坏与癌症风险联系起来的生物机制在很大程度上仍不清楚。我们证明,在 KRAS 驱动的肺癌小鼠模型中,暴露于慢性昼夜节律紊乱 [慢性时差 (CJL)] 会增加肿瘤负担。肿瘤和荷瘤肺组织的分子特征表明,CJL 增强热休克因子 1 (HSF1) 靶基因的表达。一致的是,暴露于 CJL 会扰乱肺部 HSF1 的高度节律性核运输,导致 HSF1 在细胞核中的积累增加。 HSF1 已被证明可以促进其他系统中的肿瘤发生,我们发现 HSF1 的药理学或遗传抑制可减少 KRAS 突变的人肺癌细胞的生长。这些发现表明 HSF1 是昼夜节律紊乱和肿瘤发生增强之间的分子联系。昼夜节律紊乱会增强 HSF1 信号传导,这可能会增加轮班工人的癌症风险。
Disrupted circadian rhythmicity is a prominent feature of modern society and has been designated as a probable carcinogen by the World Health Organization. However, the biological mechanisms that connect circadian disruption and cancer risk remain largely undefined. We demonstrate that exposure to chronic circadian disruption [chronic jetlag (CJL)] increases tumor burden in a mouse model of KRAS-driven lung cancer. Molecular characterization of tumors and tumor-bearing lung tissues revealed that CJL enhances the expression of heat shock factor 1 (HSF1) target genes. Consistently, exposure to CJL disrupted the highly rhythmic nuclear trafficking of HSF1 in the lung, resulting in an enhanced accumulation of HSF1 in the nucleus. HSF1 has been shown to promote tumorigenesis in other systems, and we find that pharmacological or genetic inhibition of HSF1 reduces the growth of KRAS-mutant human lung cancer cells. These findings implicate HSF1 as a molecular link between circadian disruption and enhanced tumorigenesis. Circadian disruption enhances HSF1 signaling, which could contribute to increased cancer risk in shift workers.
