The Roles of Tripartite Motif Proteins in Urological Cancers: A Systematic Review.

We aimed to investigate the roles of tripartite motif (TRIM) proteins in urological cancers. Methods: A systematic review was conducted to investigate the oncological role of tripartite motif proteins in urological cancers. Results: A total of 84 articles were identified for the final analysis (26 articles on kidney cancers, 19 on bladder cancers, 37 on prostate cancers, and 1 on testicular cancers). In total, 27 TRIM family proteins were involved in kidney cancer, of which 9 were associated with tumor-promoting findings (TRIM24, TRIM27, TRIM37, TRIM44, TRIM46, TRIM47, TRIM59, TRIM63, and TRIM65) and of which 9 TRIM proteins were tumor-suppressive (TRIM2, TRIM7, TRIM8, TRIM13, TRIM21, TRIM26, TRIM28, TRIM33, and TRIM58). Fourteen TRIM family proteins were associated with bladder cancer (tumor-promoting: TRIM9, TRIM25, TRIM26, TRIM28, TRIM29, TRIM59, TRIM65, and TRIM66; tumor-suppressive: TRIM19 and TRIM38). Ten TRIM family proteins were associated with prostate cancer (tumor-promoting: TRIM11, TRIM24, TRIM28, TRIM33, TRIM44, TRIM59, TRIM63, TRIM66, and TRIM68; tumor-suppressive: TRIM32 and TRIM36). Twenty-eight TRIM family proteins were identified to be associated with prostate cancer (tumor-promoting: TRIM11, TRIM24, TRIM28, TRIM33, TRIM44, TRIM59, TRIM63, TRIM66, and TRIM68; tumor-suppressive: TRIM32 and TRIM36). TRIM proteins regulate urological cancers by ubiquitination or modulation of oncologic pathways. Conclusions: This review identifies TRIM proteins that are involved in urological cancers. Some of these proteins have the potential to be the therapeutic target.
