Effect of Fengshi Qutong Capsule on Human Umbilical Vein Endothelial Cells Induced by VEGF / 中国实验方剂学杂志

ABSTRACT

Objective: To study the effect of Fengshi Qutong capsule on the migration, adhesion, invasion and tube formation of human synovial cells and the phosphorylation and protein expression of vascular endothelial growth factor receptor 2 (VEGFR2). Method: With human umbilical vein endothelial cells (HUVEC) as the research object, low, middle and high-dose Fengshi Qutong capsule(0.02,0.1,0.5 μg·L-1) on HUVEC was determined by methye thiazolye telrazlium (MTT) colorimetric assay for the follow-up experiment. The transwell migration, adhesion and transwell invasion test were used to detect the migration and adhesion of the different concentrations of Fengshi Qutong capsule in HUVEC. The expression of VEGFR2 in HUVEC was detected by Western blot, and Real-time PCR was used to detect the content of VEGFR2 mRNA in cells. Result: Compared with normal group, the proliferation of HUVEC was significantly increased after 24 h and 48 h of VEGF induction (PPP-1 Fengshi Qutong capsule were administered in vitro for 48 h to inhibit HUVEC proliferation activity in a dose-dependent manner (PPPPConclusion: Fengshi Qutong capsule can inhibit the migration, adhesion, invasion and tube formation of HUVEC. This effect may be related to the inhibition of phosphorylation, and protein and mRNA expression level of VEGFR2.
