Because dephosphorylation by calcineurin activates Bad, we examined the possible involvement of Bad activation in rotenone-induced apoptosis by using the calcineurin inhibitor tacrolimus (FK506).

PLoS One. 2009 May 27;4(5):e5701.

We also show that wild-type PINK1, but not recessive mutant or kinase dead versions, protects against rotenone-induced mitochondrial fragmentation whereas PINK1 deficient cells show lower mitochondrial connectivity.

12065751 Waldmeier PC, Feldtrauer JJ, Qian T, Lemasters JJ: Inhibition of the mitochondrial permeability transition by the nonimmunosuppressive cyclosporin derivative NIM811. Mol Pharmacol. 2002 Jul;62(1):22-9.

Cyclosporin A (CsA) shows cytoprotective properties in many cellular and in vivo models that may depend on interference of the interaction of cyclophilin A with calcineurin or of cyclophilin D with the mitochondrial permeability transition (PT) pore.
Using two newly developed microtiter plate assays, one measuring mitochondrial swelling from absorbance and the other measuring mitochondrial membrane potential from changes in safranin fluorescence, we show that NIM811 blocks the MPT induced by calcium and inorganic phosphate, alone or in combination with the dopaminergic neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine, the complex I inhibitor rotenone, and the prooxidant t-butylhydroperoxide.
