Objective To investigate the effect of basil polysaccharide(BPS) on the expression of vascular endothelial growth factor receptors(VEGFRs) in SKOV3 ovarian cancer cells and its involvement in regulating the invasion of SKOV3 cells. Methods Vascular endothelial growth factor(VEGF) secretion by SKOV3 cells after BPS treatment was analyzed by ELISA and the regulation of VEGFRs in SKOV3 cells by BPS was assessed by qRT-PCR and flowcytometry. Transwell assay was performed to investigate the effect of different c...
