TRIM65 (Tripartite motif containing 65)是一种E3泛素连接酶,参与多种细胞过程和肿瘤进展,但其在宫颈癌中的生物学作用和潜在机制尚不清楚。本研究发现,TRIM65在人宫颈癌组织中的表达明显高于邻近正常宫颈组织,敲低TRIM65可增强自噬通量和细胞凋亡,但不影响细胞周期,从而显著抑制宫颈癌细胞的增殖和迁移。此外,我们的实验表明,TRIM65通过直接靶向p53表现出致癌活性,p53是一种肿瘤抑制因子,也是自噬和凋亡之间常见的上行调节因子,促进p53的泛素化和蛋白酶体降解。综上所述,我们的研究表明,TRIM65敲低可通过增强自噬和凋亡促进宫颈癌细胞死亡,提示TRIM65可能是临床治疗宫颈癌的潜在靶点。
Tripartite motif containing 65 (TRIM65) is an E3 ubiquitin ligase that has been implicated in a variety of cellular processes as well as tumor progression, but its biological role and the underlying mechanism in cervical cancer is unclear. Here, we reported that TRIM65 expression in human cervical cancer tissues was significantly higher than that in the adjacent normal cervical tissues, and TRIM65 knockdown enhanced autophagic flux and cell apoptosis, but not cell cycle, to dramatically inhibit the proliferation and migration of cervical cancer cells. Furthermore, our experiments showed that TRIM65 exhibited oncogenic activities via directly targeting p53, a tumor suppressor and a common upsteam regulator between autophagy and apoptosis, promoting ubiquitination and proteasomal degradation of p53. Taken together, our studies demonstrated that TRIM65 knockdown promotes cervical cancer cell death through enhancing autophagy and apoptosis, suggesting that TRIM65 may be a potential therapeutic target for cervical cancer clinically.
