To investigate the molecular mechanisms of hepatocellular carcinoma( HCC) progression and develop novel potential therapeutic method for treatment of HCC,in the study,the role of TNFAIP1 in the cell proliferation and apoptosis to HepG2 cells was determined. MTT assay showed that overexpression and knockdown of TNFAIP1 gene could significantly inhibit and promote cell growth of HepG2 cell lines,respectively. These results imply that TNFAIP1 is involved in the inhibition of cell proliferation in HCC. Moreover...
