Abstract Ubiquitination was considered to be a crucial factor in intrahepatic cholangiocarcinoma (iCCA) development. Herein. we identified Ubiquitin-specific peptidase 8 (USP8) as a key regulator for promoting the tumorigenesis of iCCA cell via stabilizing OGT. USP8 was overexpressed in human tumor tissues and correlated with worse survival. https://www.hindigyanvishv.com/flash-deal-Iowa-Cubs-Foam-Finger-p32059-hot-value/
