Abstract:
Objective To investigate the expression of P21ras and PIK3CA proteins in hepatitis B virus-related hepatocellular carcinoma(HBV-HCC), post-hepatitis B hepatic cirrhosis (HBV-hepatic cirrhosis)and normal hepatic tissues specimen, and their correlation between HBV-HCC and HBV-hepatic cirrhosis tissues.Methods Using immunohistochemistry, the expression of P21ras and PIK3CA proteins in 34 cases of HBV-HCC, 37 cases of HBV-hepatic cirrhosis and 30 cases of normal liver tissues specimen were detected and compared. Results The mean gray scales of P21ras protein in HBV-HCC, HBV-hepatic cirrhosis and normal hepatic tissue specimen were 138.86 ± 2.9, 145. 34 ± 2.06 and 152.07 ± 1.17 (P < 0. 0l), respectively, and were related to the progression of hepatopathy (P <0.01). The mean gray scales of PIK3CA protein in HBV-HCC, HBV-hepatic cirrhosis and normal hepatic tissue specimen were 138.20 ± 3. 14, 149.49 ±0. 78 and 154.71 ± 1.29 (P < 0.01), respectively, and were related to the progression of hepatopathy (P < 0. 01).There were apparent correlation between P21ras and PIK3CA in HBV-HCC and HBV-hepatic cirrhosis respectively (r =0. 64, P <0. 05; r =0. 42, P <0. 05). Conclusion The overexpression of P21ras and PIK3CA in HCC and hepatic cirrhosis tissue suggests that they participate in the tumorigenesis and development of hepatocellular carcinoma and hepatic cirrhosis, and there may be a signal transduction pathway of P21ras-PI3K in HBV-HCC and HBV-hepatic cirrhosis.
