Estrogen Receptor β Alleviates Colitis by Inhibiting Ferroptosis in Intestinal Epithelial Cells

Ulcerative colitis (UC), a major type of inflammatory bowel disease, is characterized by chronic inflammation of the colonic mucosa and submucosa. Estrogen receptor β (ERβ) predominates in the colon and exerts anti-inflammatory effects. Ferroptosis, a recently discovered form of iron-dependent programmed cell death, is implicated in the pathogenesis of several diseases, including UC. However, the link between ferroptosis and the anti-inflammatory actions of ERβ in UC remains to be elucidated.
