ABSTRACT
Objective High mobility group box 1 (HMGB1) mediates the inflammatory immune response as well as the prolif-eration, differentiation and migration of cells , neverthless, little study has been done on the changes of HMGB 1 expression in hepatoma tissues.The aim of the article was to investigate the changes of HMGB 1 mRNA and protein expression in hepatocellular carcinoma (HCC) tissues. Methods Real-time fluorescence quantitative PCR and Western blotting were applied to detect HMGB 1 mRNA and protein expression in HCC tissues and their paracancerous tissues of 13 cases.Immunofluorescence localization was used to analyze the changes of HMGB1 distribution in hepatic cells . Results The expression of HMGB1 mRNA and protein in HCC tissues (4.01 ±0.81) and (1.37 ±0.34) increased significantly in comparison with those in paracancerous tissues (5.76 ±1.28) and (0.52 ±0.12) ( P<0.01).Nucleo-cytoplasmic translocation of HMGB1 was observed in hepatocarcinoma cells . Conclusion There is increased expression of HMGB1 in HCC tissues, which shows HMGB1 mediates the carcinogenesis of HCC .
