The Study of Interfering of Endogenous VEGF-C Genes and the Protein Expression Gastric Cancer Cell with siRNA Technique

Objective To explore the interfering effects of siRNA on endogenous VEGF-C genes and the protein expression in gastric cancer cells. Methods Cultured gastric cancer cell line SGC7901 cells were prepared in vitro. Five siRNA primers of VEGF-C were designed depending on the sequence of Accession No.BC035212.1 in Genbank. After homology analysis, the primers were synthesized and transfected into SGC7901 cells. The endogenous VEGF-C mRNA level and its protein expression were observed. Results VEGF-C-siRNA was inserted into the gastric cancer cell successfully. Five siRNA primers of VEGF-C could inhibit VEGF-C genes and protein expression. Conclusion siRNA could block the endogenous VEGF-C genes and the protein expression in gastric cancer cell.
