Objective To investigate the expressions of platelet derived growth factor (PDGF) and survivin in hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) and to evaluate the relationships among the expressions of PDGF, survivin and the proliferation of cancer cells.
Methods The expression of PDGF mRNA in 16 cases in HCC with PVTT group was observed by in situ hybridization and the results were compared with that in HCC tissue group. The expressions of PDGF and survivin protein in 36 cases in HCC with PVTT group were detected with immunohistochemistry and it was found that there was a correlation between them. Flow cytometry (FCM) was used to measure the proliferation of cancer cells and it was also used to analyze the relations among PDGF, survivin and the proliferation of cancer cells.
Results The expression level of PDGF mRNA in HCC with PVTT group was significantly higher than that in HCC tissue group (P<0.01). There was a positive correlation between the expressions of PDGF and survivin protein in HCC with PVTT (P<0.01). The degree of proliferation of cancer cells in PDGF and survivin protein positive group was significantly higher than that in negative group (P<0.01).
Conclusion PDGF and survivin gene over-expressed in HCC with PVTT group and there is a positive correlation between the expressions of PDGF and survivin protein. The proliferation of cancer cells increases as the expressions of PDGF and survivin increase.
