| Research Abstract |
We examined whether apelin is an endogenous neuroprotective factor using SOD1(G93A) mouse model of ALS. Double mutant apelin-deficient and SOD1(G93A) displayed the disease phenotypes earlier than SOD1(G93A) littermates. In addition, the number of motor neurons was decreased in the spinal cord of the double mutant mice. Furthermore, we showed that apelin enhanced the protective effect of VEGF on hydrogen peroxide-induced neuronal death in primary neurons. These results suggest that apelin/APJ system in the spinal cord has a neuroprotective effect against the pathogenesis of ALS, and that apelin may be a useful therapeutic target for ALS.
