Gpx4 methylation
WebMETTL16-regulated m6A methylation of GPX4 stimulates proliferation and suppresses ferroptosis of breast cancer cells. Therefore, we concluded that METTL16 epigenetically enhanced GPX4 expression via m6A modification to promote breast cancer progression by inhibiting ferroptosis. Keywords: Breast cancer; Ferroptosis; METTL16; m6A methylation. WebSep 8, 2024 · GPX4 converts lipid hydroperoxide, which is potentially toxic, to a non-toxic form of lipid alcohol ( Ursini et al., 1982 ). Therefore, inactivation or inhibition of the enzyme GPX4 triggers overwhelming lipid peroxidation that causes iron-dependent cell death.
