Abstract

In vitro studies tested the efficacy of three caspase inhibitors, Ac- VAD-cmk (caspase-1 inhibitor), z-DEVD-fmk (caspase -3 inhibitor) and B-D-fmk (BOCDFK, a general inhibitor), for protecting auditory sensory cells from cisplatin-damage induced loss. Treatment of 3-day-old rat organ of Corti explants with these caspase inhibitors protected > 80% of the auditory hair cells from cisplatin-damage initiated apoptosis. Dissociated cell cultures of 3-day-old rat spinal ganglia treated with any of these three caspase inhibitors in addition to exogenous neurotrophin have highly significant increases in neuronal survival following cisplatin exposure. These results indicate that loss of auditory sensory cells as a result of cisplatin- induced damage involves apoptosis and that blocking of this cell death pathway at the caspase level effectively rescues both hair cells and neurons.
