Although the presence of ferroptosis was first demonstrated in cancer, given the increasing number of associated studies, ferroptosis has been shown to fulfill an important role within the nervous system (11,2630), and common neurological disorders, including ischemic stroke (31), Alzheimer's disease (32) and Parkinson's disease (33), have been found to be closely associated with ferroptosis, the latter two being common neurodegenerative disorders wherein the molecular mechanism is mainly concerned with an aggregation of iron in the hippocampal region of the brain or in dense areas of the substantia nigra, and these responses have been shown to be inhibited by the ferroptosis inhibitor, ferrostatin-1 (Fer-1) (3436)

When levels run low, skin can look duller and more uneven

564 HO-1 and GPX4 were downregulated due to Nrf2 defects in astrocytes, leading to increased mitochondrial fragmentation, DNA oxidation, and lipid peroxidation in mouse astrocytes, 564 suggesting that Nrf2 deficiency promotes ferroptosis in astrocytes in AD mice

The levels of positive staining were quantified as the mean fluorescence intensity using ImageJ software [21]
