pubmed:abstractText |
The use of the immunosuppressive drug cyclosporine A (CSA) is restricted by its nephrotoxicity. Perturbation of Ca2+ homeostasis has been implicated in chemical toxicity. Mitochondria, a key regulator of Ca2+ homeostasis, may be a target of the drug. Here we show that CSA inhibits at low concentrations the prooxidant-induced but not the sodium-induced Ca2+ release from rat kidney mitochondria. CSA does not affect Ca2+ uptake by mitochondria. Inhibition of Ca2+ release is due to inhibition of intramitochondrial enzymatic hydrolysis of NAD+ to ADP-ribose and nicotinamide. These findings suggest a very specific effect of CSA on mitochondrial Ca2+ release by which the drug interferes with cellular Ca2+ homeostasis. This is possibly the basis of CSA nephrotoxicity.
