Study Unveils Dual Role of 7-DHC in Ferroptosis and Cancer Cell Survival

Cell death is fundamental to life and, thus, healthy aging. In the realm of cellular biology, ferroptosis (a form of programmed cell death) has emerged not only as a focal point of research for its potential in eliminating cancer cells, but also its role in a plethora of other diseases, including neurodegenerative diseases such as Alzheimer's disease, eye diseases such as Retinitis pigmentosa and age-related macular degeneration, as well as ischemia, cardiovascular disease, liver disease, acute kidney injury and inflammation.
