Overexpression of TDO2 restrained the proliferation of HepG2 and HLF cells. (a, b) Western blot showing that TDO2 was overexpressed in transfected HLF and HepG2 cells. (c, d) CCK8 assay showing that overexpression of TDO2 could restrain the proliferation of HLF and HepG2 cells. (e, f) Overexpression of TDO2 reduced the colony formation of HLF and HepG2 cells. (g, h) Column chart of the colony formation of HLF and HepG2 cells stably transfected with a TDO2-overexpression vector or the empty vector control.
