mitochondrial damage can further amplify inflammation via ROS generation and impaired ATP production ( Carnitine transport, homeostasis, and substrate selection Meldonium not only inhibits GBB hydroxylase but also blocks the high-affinity organic cation/carnitine transporter OCTN2 (SLC22A5), which mediates cellular uptake and renal reabsorption of carnitine ( Animal studies in skeletal and cardiac muscle show that this disturbance of carnitine homeostasis diminishes fatty-acid -oxidation and increases reliance on carbohydrate oxidation for ATP production, especially under hypoxic or ischemic conditions ( and PPAR , consistent with mitochondrial and peroxisomal remodeling ( in vivo , and its inhibition of the carnitine/acylcarnitine translocase is comparatively weak

SQOR-mediated persulfide formation, another anti-ferroptotic mechanism Beyond its role in ubiquinol (CoQ 10 H 2 ) generation, SQOR also contributes to ferroptosis resistance through the production of persulfide-containing metabolites
