Zedoarondiol Inhibits Neovascularization in Atherosclerotic Plaques of ApoE Mice by Reducing Platelet Exosomes-Derived MiR-let-7a.

Objective: To investigate the effect of zedoarondiol on neovascularization of atherosclerotic (AS) plaque by exosomes experiment.

Methods: ApoE mice were fed with high-fat diet to establish AS model and treated with high- and low-dose (10, 5 mg/kg daily) of zedoarondiol, respectively. After 14 weeks, the expressions of anti-angiogenic protein thrombospondin 1 (THBS-1) and its receptor CD36 in plaques, as well as platelet activation rate and exosome-derived miR-let-7a were detected.

Zedoarondiol inhibits monocyte adhesion and expression of VCAM and ICAM in endothelial cells induced by oxidative stress.

Zedoarondiol, a newly discovered compound derived from the roots of zedoary turmeric, a traditional Chinese herb, has demonstrated potential in reducing inflammation of the vascular endothelium and safeguarding it from harm. Nonetheless, the precise mechanism underlying these effects remains to be elucidated. In this study, we established a model of HUVEC injury induced by hydrogen peroxide.
