There were increases in several putative ferroptosis markers, including lipid peroxidation-derived 4-hydroxynonenal (4-HNE) staining (Figure 7) [27], malondialdehyde (MDA) levels [28], and prostaglandin-endoperoxide synthase 2 (Ptgs2) [28] and solute carrier family 7, member 11 (Slc7a11) [28] mRNA levels in SCD mice liver (Figure 7). The gene discussed is SLC7A11; the disease is Schnyder corneal dystrophy.
