Expressions of STAT3 gene in human hepatocellular carcinoma cell lines HepG2,Bel7402,SMMC7721 and hepatocellular carcinoma tissues and their significances
Objective To explore the role and possible mechanism of abnormal activation of STAT3 gene during the occurrence and development of human hepatocellular carcinomar(HCC).Methods Immunohistochemistry dyeing,RT-PCR and Western blotting were used to detect the mRNA and protein expressions of STAT3 gene in HCC cell lines SMMC7721,Bel7402 and HepG2 and human HCC tissues.Results There were high expressions of STAT3 gene in SMMC7721,Bel7402 and HepG2 cells,and there was no significant difference among them(P>0.05).T...
