In the present study, we analyzed the expression of PKCs in human hepatocellular carcinoma (HCC) tissues and explored their roles in the development of HCC., we used real-time quantitative RT-PCR, mutation analysis, and immunohistochemical staining to investigate the expression of PKCs in 50 pairs of human hepatocellular carcinoma (HCC) tissues. Results showed that PKC β and PKCθ were down-regulated in HCC tissues. Reduced expression of PKC θ is well correlated with the grade of cancer cells (p=0.009), and the down-regulated expression of PKC βII is associated with HBV infection (P=0.035). From these results, we suggest that the expression of PKC θ and PKC β may have clinical significance in HCC. Specialy, our data showed that the expression of PKCη is down-regulated in 82% of HCC tissues. The down-regulation is associated with poorer long-term survival of HCC patients. These results suggest that PKC η plays a tumor suppressor-like role in the development of HCC. Fen-Pi Chou 周芬碧 2010 學位論文 ; thesis 81 zh-TW |
