Abstract:
Objective To study the expression of a virulent novel gene F10 associated with hydatidiform mole in the hepatoma carcinoma cells(HCC),and to explore the effects of F10 on the occurrence and development of primary hepatocellular carcinoma(PHC).Methods The full-length cDNA sequence of F10 was obtained from the samples of early pregnant chorionic villi and hydatidiform mole by employing suppression subtractive hybridization and cDNA microarray techniques.The hepatocarcinoma tissues and their surroundings were examined by in situ hybridization with digoxigenin-labeled of F10 gene.The real-time-fluorescence quantitative polymerase chain reaction(FQ-PCR)was used to quantitatively detect the expression level of F10 gene in primary hepatocellular carcinoma.F10 gene RNA copies in the samples were examined in the hepatocarcinoma tissues samples and their surroundings with PHC by PE ABI 7000 Sequence Detector.Results F10 mRNA was detected in hepatocarcinoma cells with positive signals found in kytoplasm and cell membrane,but not detected in the tissues surrounded the hepatocarcinoma.In 6 of 8 PHC samples,the expression Level of F10 gene was higher in tumor tissues than that in the tissues surrounded the tumor tissue.Among them 2 cases showed more than 4 times over-expression of F10 gene in tumor cells than in the surrounded tissues.Conclusion The virulent new F10 gene associated with hydatidiform mole was mainly expressed in hepatocellular carcinoma cells.The results of present study suggested that the higher expression of F10 gene not only showed a close relation to trophoblastic tumor,but also indicated that the F10 gene may play an important role in the occurrence and development of primary hepatocellular carcinoma.
