Abstract

Cardiotrophin-1 (CT-1) was initially defined as a mediator of cardiomyocyte hypertrophy. Additional studies have showed that CT-1 enhanced survival of differentiated cardiac muscle cells and inhibited cardiac myocyte apoptosis after serum deprivation or cytokine stimulation. Moreover, CT-1 has recently been shown to act as a neuroregulatory cytokine in the peripheral nervous system. However, its effects in the central nervous system have not been determined. In the present study, we evaluated whether CT-1 protects cultured cortical neurons against oxidative injuries caused by the hydroxyl radical-producing agent FeSO4 and by the peroxynitrite-producing agent 3-morpholinosydnonimine (SIN-1). CT-1 reduced neuronal cell death caused by FeSO4 and also attenuated the neurotoxic effect of SIN-1 in a dose-dependent manner. These results indicate that CT-1 is neuroprotective in an in vitro model of cerebral ischemia. This study indicates that further evaluation of CT-1 in acute brain injury should be investigated in vivo.
