WebOct 3, 2024 · Consistently, GPX4 overexpression in ApoE −/− mice was shown to protect against atherosclerosis (Guo et al. 2008). Conversely, iron overload is one crucial characteristic of ferroptosis and was reported to promote atherosclerosis (Vinchi et al. 2024). In this study, we found that ferroptosis was induced during injury-induced vascular ...

WebApr 13, 2024 · Overexpression of ENPP2 could obviously induce the protein expression of GPX4, which is a marker protein of oxidative stress (Fig. 6A, C). In contrast to this, overexpression of ENPP2 could obviously repress the protein expression of ACSL4, indicating that the ferroptosis was alleviated in HCMECs (Fig. 6A, D). The angiogenesis … WebAug 12, 2024 · Background Glutathione Peroxidase 4 (GPX4) is a key protein that inhibits ferroptosis. However, its biological regulation and mechanism in endometrial cancer (EC) have not been reported in detail. Methods The expression of GPX4 in EC tissues was determined by TCGA databases, qRT-PCR, Western blot, and immunohistochemistry … WebJan 22, 2024 · Genetic-overexpression of GPX4 effectively increased level of GPX4 in the brain, and clearly relieved neuronal dysfunction, brain edema, blood brain barrier (BBB) injury, oxidative stress and inflammation after ICH.
