Propofol inhibited HepG2 cell proliferation (A) Effect of propofol (at 0.3, 0.6, 1.2, 2.5, 5, 10, 20, 40, 80 and 160 µM) on HepG2 cell viability were measured using a CCK-8 kit; (B) the mRNA expression levels of PCNA (proliferating cell nuclear antigen) and survivin were detected by qRT-PCR (quantitative real-time reverse transcription-polymerase chain reaction) in the propofol 0 µM group (control group), propofol 5 µM group, propofol 10 µM group, and propofol 20 µM group; (C) the protein expression levels of PCNA and survivin were detected by western blot. *, P<0.05; **, P<0.01 versus propofol 0 µM group.
