“…In amino acid metabolic pathways, homocysteine is an intermediate amino acid that is metabolized from methionine to cysteine and has been shown to be associated with oxidative stress and endothelial damage [ 27 ]. Glutathione (GSH), superoxide dismutase (SOD), and glutathione peroxidase (GPX) are major antioxidant molecules in ECs [ 28 ]. A recent report showed that brain ECs directly absorb and metabolize glutamate and utilize the resulting α-ketoglutarate in the tricarboxylic acid cycle, ultimately producing ATP in the absence of glucose [ 29 ].…”

“…We previously showed that IDH2 downregulation induced mitochondrial dysfunction by disrupting mitochondrial dynamics and increasing mitochondrial oxidative stress [ 9 ]. PINK1/Parkin-regulated mitophagy preserves mitochondrial function and concomitantly prevents endothelial senescence [ 14 , 15 ]. Therefore, we investigated the mRNA and protein levels of Sirt3, PINK1, and Parkin in IDH2-knockout HUVECs.…”

“…UA inhibits mitochondrial fission, restores mitochondrial fusion and reduces the proportion of mitochondrial fragments in endothelial cells. UA enhances mitochondrial biogenesis in endothelial cells by upregulating Sirtuin 3 and peroxisome proliferator-activated receptor γ coactivator 1-α [ 81 ]. These results suggest that activation of mitochondrial autophagy may alleviate cardiac microvascular injury induced by hypoxia/reoxygenation by improving mitochondrial quality control, cell viability and proliferation.…”
