Aim.
To explore whether Chinese traditional medicine, tongxinluo (TXL), exerts beneficial effects on endothelial dysfunction induced by homocysteine thiolactone (HTL) and to investigate the potential mechanisms.
Methods and Results.
Incubation of cultured human umbilical vein endothelial cells with HTL (1 mM) for 24 hours significantly reduced cell viabilities assayed by MTT, and enhanced productions of reactive oxygen species.
Pretreatment of cells with TXL (100, 200, and 400 μg/mL) for 1 hour reversed these effects induced by HTL.
Further, coincubation with GW9662 (0.01, 0.1 mM) abolished the protective effects of TXL on HTL-treated cells.
In ex vivo experiments, exposure of isolated aortic rings from rats to HTL (1 mM) for 1 hour dramatically impaired acetylcholine-induced endothelium-dependent relaxation, reduced SOD activity, and increased malondialdehyde content in aortic tissues.
Preincubation of aortic rings with TXL (100, 200, and 400 μg/mL) normalized the disorders induced by HTL.
Importantly, all effects induced by TXL were reversed by GW9662.
In vivo analysis indicated that the administration of TXL (1.0 g/kg/d) remarkably suppressed oxidative stress and prevented endothelial dysfunction in rats fed with HTL (50 mg/kg/d) for 8 weeks.
Conclusions.
TXL improves endothelial functions in rats fed with HTL, which is related to PPARγ-dependent suppression of oxidative stress.
