| Outline of Final Research Achievements |
We experimentally evaluated the clinical application of N-methyl-4-isoleucine cyclosporin, a novel selective inhibitor of cyclophilin D activation. In vitro, calcium oxalate monohydrate crystals induced depolarization of the mitochondrial membrane potential, which was remarkably prevented by N-methyl-4-isoleucine cyclosporin. In vivo, ethylene glycol administration induced renal calcium crystallization, oxidative stress, mitochondrial collapse and cell apoptosis in rats, which were significantly prevented by N-methyl-4-isoleucine cyclosporin.Herein we first report a new treatment agent determining renal calcium crystallization through cyclophilin D activation.
