The current review reported on FSP1 inhibitors that boost cancer-cell sensitivity to ferroptosis
In further studies, only the formation of [14C]carbon dioxide from [14C-1]glucose was measured, with the addition of: sodium ascorbate (which undergoes a non-enzymic reaction in air to produce hydrogen peroxide) acetylphenylhydrazine (which is known to precipitate haemolysis in sensitive subjects, and depletes glutathione) methylene blue (which oxidises NADPH) All incubations were repeated in the presence and absence of N -ethylmaleimide, which undergoes a non-enzymic reaction with the -SH group of reduced glutathione, and thus depletes the cell of glutathione

Results clearly showed that the tyrosine-nitration level was reduced in proportion to the molar ratios of GSSSG and LASSS relative to HGF, as revealed by the decrease in anti-nitroY mAb-positive HGF (60-kDa -chain and 90-kDa proform) normalized to total HGF -chain as a loading control, that was monitored by stripping with SDS-ME solution and re-probing the blot with anti-HGF -chain N-terminal domain mAb (Figure 1b,c, second and third rows)
