Research Progress on Ferroptosis,Ulcerative Colitis and Treatment with Traditional Chinese Medicine
Ulcerative colitis is a chronic,non-specific inflammatory disease.The persistent damage to its intestinal epithelium is key to the development of the disease.In recent years,a new form of cell death has been identified by researchers-iron death-which is thought to be an important contributor to intestinal epithelial cell death.The occurrence of iron death is often associated with abnormal intracellular iron metabolism,reduced cystine/glutamate reverse transporter activity,abnormal lipid metabolism,voltage-dependent anion channel activation and overexpression of the Nrf2 gene.Iron death can lead to smaller mitochondria,increased membrane density and reduced number of cristae,unlike conventional cell death,which does not exhibit specific phenomena.Studies have found that TCM can alleviate iron death in intestinal epithelial cells by reducing intracellular iron content,inhibiting lipid reactive oxygen species production and regulating Nrf2 gene expression,thus acting as a treatment for ulcerative colitis.Therefore,Chinese medicine may become an important tool for the treatment of ulcerative colitis.This paper reviews the relationship between cellular iron death and ulcerative colitis and the research progress of Chinese medicine in treating ulcerative colitis through the iron death pathway.
