Although emerging studies showed that certain rhythm genes regulate cancer progression, the expression and roles of the vast majority of rhythm genes in human cancer are largely unknown, and the hallmarks of cancer regulated by rhythm genes have not been detected. In this study, we detected the expression changes of rhythm genes in pan-cancer and found that almost all rhythm genes mutated in all cancer types, and their expression level was significantly altered partially due to abnormal methylation, and several rhythm genes regulate the expression of other rhythm genes in various cancer types. Furthermore, we revealed that rhythm genes are significantly enriched in genome instability and the expression of certain rhythm genes is correlated with the tumor mutation burden, microsatellite instability, and the expression of DNA damage repair genes in most of the detected cancer types. Moreover, rhythm genes are associated with the infiltration of immune cells and the efficiency of immune blockade therapy. This study provides a comprehensive understanding of the roles of rhythm genes in cancer immunity, which may provide a novel method for the diagnosis and treatment of cancer.

节奏基因的异常表达影响基因组的不稳定性,并调节泛癌中的癌症免疫力。

尽管新兴的研究表明某些节律基因可调节癌症的进展,但绝大多数节律基因在人类癌症中的表达和作用尚不清楚,并且尚未检测到由节律基因调节的癌症标志。在这项研究中,我们检测了泛癌中节奏基因的表达变化,发现在所有癌症类型中几乎所有的节奏基因都发生了突变,并且它们的表达水平由于甲基化异常而部分改变了,并且一些节奏基因调节了该基因的表达。各种癌症类型中的其他节奏基因。此外,我们发现节律基因在基因组不稳定性中明显丰富,某些节律基因的表达与肿瘤突变负担,微卫星不稳定性,以及大多数检测到的癌症类型中DNA损伤修复基因的表达。此外,节奏基因与免疫细胞的浸润和免疫阻断疗法的效率有关。这项研究提供了对节奏基因在癌症免疫中的作用的全面理解,这可能为癌症的诊断和治疗提供一种新颖的方法。
