In a recent study, Li et al. found that ferroptosis in ectopic endometrial stromal cells in patients with ovarian endometriosis could activate the p38 mitogen-activated protein kinase (p38 MAPK)/signal transducer and activator of transcription (STAT) 6 signalling pathway, thereby promoting local upregulation of vascular endothelial growth factor A (VEGFA) and interleukin-8 (IL-8) in ectopic lesions [15]. This evidence concerns the gene VEGFA and ovarian endometriosis.
