UBE2S and hepatocellular carcinoma: To evaluate the effect of UBE2S on HCC progression in vivo, HCCLM3 cells with stable knockdown of UBE2S expression (named UBE2S‐shRNA HCCLM3) and Bel‐7402 cells with stable overexpression of UBE2S (named UBE2S‐ overexpression Bel‐7402) were established via lentivirus transfection.
