Does Ginsenoside Rb1 attenuate coronary microvascular inflammatory injury in murine models of ischemia-reperfusion?
Ginsenoside Rb1 protects against ischemia-reperfusion injury by modulating mitochondrial quality control and reducing inflammation via the NDUFS4-SIRT5-DUSP1 axis.
Background: Ginsenoside Rb1 is a prominent bioactive component in traditional Chinese medicine. Purpose: This study investigated the molecular mechanisms underlying the protective effects of Ginsenoside Rb1 on endothelium during ischemia-reperfusion (I/R) injury. Materials and methods: mouse models were established using gene modification techniques. Si-DUSP-1/ad-DUSP-1 and si-SIRT5/ad-SIRT5 cell models were constructed. Fluorescence detection, mitochondrial membrane potential assays, RT-PCR, and Western blotting were employed to detect the mitochondrial function. Results: NDUFS4 and DUSP1 regulate the mitochondrial unfolded protein response (mtUPR), energy metabolism, and dynamics, and may be crucial regulatory genes in the development of coronary artery disease. Ginsenoside Rb1 modulates the NDUFS4-SIRT5-DUSP1 axis, regulates the mitochondrial quality control network, and alleviates coronary microvascular inflammatory injury. Conclusions: Ginsenoside Rb1 regulates the NDUFS4-SIRT5-DUSP1 axis, modulating the mitochondrial quality control network, inhibiting the inflammatory cascade response, and improved myocardial function.
