摘要

超过50%的前列腺癌中存在跨膜丝氨酸蛋白酶2(TMPRSS2)和E26(ETS)转录因子间的基因融合, 其中 TMPRSS2-ERG最为常见。TMPRSS2-ERG基因融合造成的ERG过表达参与了前列腺的癌变。雄激素受体结合和遗传毒性胁迫共同诱导了染色体的靠近和TMPRSS2-ETS的基因融合。TMPRSS2-ERG基因融合可作为前列腺癌诊断的一种生物标志物, 并可通过病人尿液检测来实现。文章对TMPRSS2-ETS基因融合的特征、融合及致癌及临床应用进行了综述。

Abstract

The gene fusions between transmembrane protease serine 2 (TMPRSS2) and E26 (ETS) transcription factors are present in over 50% of patients with prostate cancer. TMPRSS2-ERG is the most common gene fusion type. The ERG overexpression induced by TMPRSS2-ERG gene fusion contributes to the development of prostate cancer. Both androgen receptor binding and genotoxic stress induce chromosomal proximity and TMPRSS2-ETS gene fusions. TMPRSS2-ERG gene fusion functions as a biomarker for prostate cancer, which can be easily detected in urine. This review focuses on the characteristics, oncogenic and rearranged mechanism, and clinical application of TMPRSS2-ETS gene fusions.
