عنوان انگلیسی The Effect and Mechanism of Vascular Endothelial Growth Fac-tor (VEGF) on Tumor Angiogenesis in Gallbladder Carcinoma
چکیده انگلیسی مقاله   Background: To investigate the effect of vascular endothelial growth factor (VEGF) on tumor angiogenesis in gallbladder carcinoma. Methods: Fifty one patients with gallbladder carcinoma were enrolled as observation group. Thirty healthy people were included as control group. Chemically synthesized siRNA sequences targeting VEGF was transfected with VEGF-siRNA. A blank group (group B), a negative control group (transfected with independent sequence, group C), and an inhibition group (transfected with VEGF siRNA, group D) were established. Physiological saline was set as group A. The expression of VEGF was detected by qRT-PCR. The expression of VEGF protein was detected by Western blot. MVD was used to measure microvessel density. CCK-8, Transwell and flow cytometry were used to detect cell proliferation, invasion and apoptosis. Results: The tumor volume of nude mice and VEGF mRNA expression in group D was significantly smaller than that in group B and C (P< 0.05). The MVD density in group B and C was significantly higher than that in group D (P< 0.01). The proliferation of cells was detected from the 3rd day, and the proliferation of cells in the blank and negative control groups was faster than that of the inhibition group (P< 0.05). The apoptosis rate of the blank group and the negative control group was lower than that of the inhibition group (P< 0.001). Conclusion: VEGF is highly expressed in serum of patients with cholangiocarcinoma, it promotes angiogenesis, proliferation and invasion of gallbladder cancer cells, and inhibits apoptosis of tumor cells.
