Function of STAT3 in hepatocellular carcinoma. a STAT3 in hepatocellular carcinoma was evaluated by IHC. b STAT3 in hepatocellular carcinoma tissue was explored by qRT-PCR. c STAT3 in hepatocellular carcinoma cell lines. d Transfection efficiency of si-STAT3 in Huh7 cells. e, f STAT3 inhibition reduced Huh7 cell proliferation and invasion abilities. g, h High STAT3 levels were correlated with poor prognosis in hepatocellular carcinoma patients. *p < 0.05
