Selenium alleviates dextran sulfate sodium‐induced colitis and inhibits ferroptosis of intestinal epithelial cells via upregulating glutathione peroxidase 4

Selenium, an essential micronutrient for humans, has been shown to be protective against ulcerative colitis (UC), but the exact mechanism remains unclear. The role of selenium, protecting against ferroptosis of intestinal epithelial cells (IECs) in colitis, was investigated in this current study.
