METHODS: Primary cultures of TM cells from POAG (GTM) and age-matched, nondiseased (NTM) eyes, obtained from postmortem donors eyes by standard surgical trabeculectomy, were treated with the following calcium regulators: the mitochondrial respiratory chain I inhibitor rotenone (ROT); the mitochondrial permeability transition pore (MPTP) inhibitors cyclosporine (Cys) and aristolochic acid (ArA); the Ca (2+) chelators BAPTA/AM or EDTA; the mitochondrial Ca (2+) uniporter inhibitor ruthenium red (RR); the Ca (2+)/Na (+) exchanger inhibitor trifluoperazine; and the inositol 1,4,5-triphosphate receptor type 3 (IP3R) inhibitors 2-aminoethoxydiphenyl borane (2-APB) and xestospongin C (Xe-C).
The expression of cyclophilin D, a protein that induces MPTP opening was also measured.

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.

At concentrations that were fully effective at inhibiting the permeability transition, these arginine reagents (i) had no effect on the isomerase activity of cyclophilin D and (ii) did not affect the rate of ATP translocation and hydrolysis, as measured by the production of a membrane potential upon ATP addition in the presence of rotenone.
