OTUD6B and nonpapillary renal cell carcinoma: Lentivirus-mediated overexpression of OTUD6B-AS1 significantly reduces cell proliferation and promotes cell apoptosis in clear cell renal cell carcinoma (ccRCC), while OTUD6B-AS1 overexpression of β-catenin reduces the activity of the Wnt/β-catenin pathway and partially inhibits cell migration and invasion [19].
