The human HCC cell lines, HEP3B217, HUH7, HEPG2, SNU398, SNU878, HUH6, SKHEP1 and PLCPRF5, were provided by Erasmus University (Rotterdam, Netherlands). MHCC97H were provided by the Liver Cancer Institute of Zhongshan Hospital (Shanghai, China). These cells were maintained in Dulbecco's modified Eagle's medium (DMEM) (Gibco, Carlsbad, CA) supplemented with 10% fetal bovine serum (FBS) (Gibco) and 1% penicillin/streptomycin (BasalMedia), incubated at 37 °C in humidified atmosphere with 5% CO2. Mycoplasma contamination was excluded via a PCR-based method. The information of TP53 mutation status of cell lines used in this study was achieved from our previous publication 54 (link). The identities of all the cell lines were confirmed by short tandem repeat (STR) profiling. Volasertib (S2235) and GSK461364 (S2193) were purchased from Selleck Chemicals and dissolved in dimethyl sulfoxide (DMSO) using a storage concentration of 10 mM.
