OTUD3 and uterine carcinosarcoma: Through the analysis of the GEPIA2 database and the expression level differences of OTUD3 in various tumors and corresponding control tissues from The Cancer Genome Atlas (TCGA), we observed a significant downregulation of OTUD3 in multiple tumors such as Ovarian Serous Cystadenocarcinoma (OV), Testicular Germ Cell Tumors (TGCT), Uterine Corpus Endometrial Carcinoma (UCEC), and Uterine Carcinosarcoma (UCS).
