dc.description.abstract | Central events in the mitochondrial-dependent cell death pathway include the disruption of mitochondrial membrane potential, which causes the release of apoptogenic molecules leading to cell death. Based on the cytotoxic mechanism of deltamethrin (DLM), we examined the neuroprotective mechanisms of rosiglitazone (RGZ), which is against DLM-induced neuronal cell death. In this study, we found that DLM induces apoptosis in SH-SY5Y cells as demonstrated by the activation of caspase-3 and nuclear condensation. In addition, neuronal cell death in response to DLM was due to mitochondrial dependent-apoptosis pathways since DLM increased cytochrome c release into the cytosol and activated caspase-9. DLM exposure reduced PINK1 expression, and pretreatment with RGZ significantly reduced cytochrome c release and caspase-9 activation. RGZ also attenuated the reduction of complex I activity, mitochondrial membrane potential, and ATP levels. Pretreatment with RGZ significantly enhanced PINK1 expression in DLM-exposed cells. In addition, RGZ increased cytosolic PINK1 by inhibiting mitochondrial translocation of PINK1. Interestingly, RGZ fails to rescue DLM-induced mitochondrial dysfunction both in PINK1 knockdown and PPAR-g antagonist treated cells. Results from this study suggest that RGZ exerts anti-apoptotic effects against DLM-induced cytotoxicity by attenuation of mitochondrial dysfunction through cytosolic PINK1-dependent signaling pathways. | - |
