“Mitophagy inhibition by cyclosporine A (CsA) partially eliminated the protective effects of melatonin against NP cell apoptosis, suggesting that mitophagy is involved in the protective effect of melatonin on IDD.”
“Addition of Mel and CsA has shown significant restoration in mitochondrial swelling, Δψm, intracellular ROS measurement and mitochondrial respiration in isolated brain mitochondria.”
“Therefore, these findings indicate that melatonin in combination with CsA protected the cardiac allograft by inhibiting inflammation‑induced apoptosis.”
“When CsA (5 mg/kg/day) was co‑administered with melatonin (50 mg/kg/day), the survival rate improved (31.6±2.4 days; n=7; P<0.001), compared with that achieved by only 20 mg/kg/day CsA (22±2.8 days; n=7).”
“ Melatonin ’s effect in reducing the Ca2+ load greatly diminished when the MPT was inhibited by cyclosporine A , suggesting its pore dependency as well as that a preserved t‐MPT may be superior to a MPT inhibition in protecting mCa2+‐mediated apoptosis.”
“Surprisingly, in the presence of cyclosporin A , a MPT inhibitor, melatonin reduced further mCa2+‐mediated apoptosis during ionomycin exposure also suggesting its targeting beyond the MPT.”
“Finally, we show that, (i) melatonin significantly reduces CsA cardiotoxicity acting also on apoptotic processes, and (ii) the reduction in CsA‐induced cardiotoxicity is mediated mainly by its antioxidant effect.”
“In conclusion our study shows that, (a) melatonin significantly reduces CsA cardiotoxicity, and (b) the reduction in CsA‐induced cardiotoxicity was mediated by the binding of melatonin to its membrane receptors.”
