摘　　要：雄激素受体(androgen receptor,AR)及其介导的信号通路异常与人类多种疾病的发生、转归及预后密切相关,并在一定程度上导致疾病的性别差异,其具体机制尚不明确。AR基因第1外显子CAG短串联重复序列(short tandem repeat,STR)与AR转录调节活性存在负相关性,影响靶蛋白合成与生物学功能,在前列腺癌、乳腺癌、膀胱癌、肝癌、子宫内膜癌等多种肿瘤发生发展及预后中扮演重要角色。本文对目前AR基因CAG STR与常见肿瘤相关性研究进行综述,为进一步探索AR导致相关肿瘤高发和性别差异作用机制和筛选肿瘤高危人群提供线索。Abnormal expression of androgen receptor(AR)and AR-mediated signaling pathways are closely related to the occurrence,outcome,and prognosis of various human disease,and to some extent,AR lead to gender differences in these diseases.However,the specific mechanism is still unclear.CAG short tandem repeat(STR)sequence in exon 1 of AR gene negatively correlates with the transcriptional regulation activity,affects the synthesis and biological function of the target proteins,and plays an important role in the development and prognosis of various tumors,such as prostate cancer,breast cancer,bladder cancer,liver cancer,and endometrial cancer.In this review,we summarized the current studies on the association between AR gene CAG STR and the common tumors,in order to provide clues for further exploring the mechanism of AR-related tumors with high incidence and gender differences,and screening populations with high risk for the corresponding tumors.
