its a question that gets to the very heart of how this peptide may function
The regulated expression of erythropoietin by two human hepatoma cell lines
Conversely, upregulation of FTL1 and ferritin heavy chain (FTH1), or inhibition of NCOA4, can suppress ferroptosis ( in vitro model of Erastin-induced ferroptosis in PC12 neuronal cells, the iron inhibitor curcuminpolydopamine nanoparticles (Cur-PDA NPs) markedly enhanced the chelation of Fe 3+ and Fe 2+ , upregulated superoxide dismutase (SOD) and GSH expression, reduced Fe 2+ and ROS levels, inhibited lipid peroxidation, restored mitochondrial function, and attenuated neuronal ferroptosis
