Abstract:
This article was aimed to study the protective effects and mechanism of resveratrol (Res) on endothelial injury induced by atherosclerosis ( AS ) . Lysophosphatidylcholine ( LPC ) was applied to induce the model of injured endothelial cells. Flow cytometer was used to detect the rate of cell apoptosis. TUNEL staining was used to detect the cell apoptosis. MTT colorimetric test was used to detect the cell viability. Automatic biochemistry analyzer was used to measure the LDH level . ELISA was used to detect TNF-α level . RT-PCR was used to determine the mRNA levels of calcitonin gene-related peptide (CGRP). The results showed that Res with the concentration of 20 μmol/L can effectively slow down the degree of endothelial cell injury induced by LPC which caused the cell disability, high LDH level and high TNF-α level (P < 0.01). Res showed effects on mRNA expression of CGRP. It was concluded that Res can protect against endothelial injury induced by AS, the mechanism of which may be associated with accelerating CGRP synthesis and release by activating VR1.
