Energy stress depletes ATP and induces cell death. Here we identify an unexpected inhibitory role of energy stress on ferroptosis, a form of regulated cell death induced by iron-dependent lipid peroxidation. We found that ferroptotic cell death and lipid peroxidation can be inhibited by treatment...
Ferroptosis, an iron-dependent form of nonapoptotic cell death mediated by lipid peroxidation, has been implicated in the pathogenesis of multiple diseases. Subcellular organelles play pivotal roles in the regulation of ferroptosis, but the mechanisms underlying the contributions of the mitochond...
Ferroptosis is an iron-dependent form of cell death driven by lipid peroxidation. Here, we identify spermine—a polyamine derived from spermidine—as an endogenous iron chelator that directly suppresses ferroptosis. Integrating metabolomics, stable isotope tracing, and biophysical studies of the in...
There is positive causality between coffee consumption and osteoarthritis (OA), however, whether gut microbiota is involved in it needs to be discussed. Here, we observed that, in caffeine consumers, fecal Prevotella copri (P. copri) abundance was positively correlated with subchondral bone mass,...
Ferroptosis is mediated by lipid peroxidation of phospholipids containing polyunsaturated fatty acyl moieties. Glutathione, the key cellular antioxidant capable of inhibiting lipid peroxidation via the activity of the enzyme glutathione peroxidase 4 (GPX-4), is generated directly from the sulfur-...
Ferroptosis, an iron-dependent form of regulated cell death, has emerged as a key driver of intestinal epithelial injury in inflammatory bowel disease (IBD). The Nrf2–GPX4 signaling axis provides a critical defense against ferroptotic damage; however, its therapeutic modulation remains underexplo...
Bisphenol F (BPF), a widespread environmental contaminant and a major substitute for the restricted bisphenol A (BPA), has raised increasing concerns regarding its potential male reproductive health risks, yet its underlying mechanisms remain poorly understood. This study investigates t...
