Popis: Background: Glutamate-induced excitotoxicity is a well-recognized cause of neuronal cell death and nutritional supplementation with Coenzyme Q10 (CoQ10) has previously been shown to have neuro-protective actions against it. The objective of this study was to determine whether the protective effect of CoQ10 against glutamate could be attributed to stimulating mitochondrial biogenesis. Results: The mouse hippocampal neuronal HT22 cells were incubated with glutamate with or without ubisol Q10 treatment. Significant deterioration of cells after glutamate exposure was observed under a light microscope and cell viability assay, along with a significant drop in clonogenic ability. Glutamate significantly decreased the mitochondrial biogenesis related protein levels of Akt, CREB, PGC-1α, and NRF2, and reduced mitochondrial biogenesis assessed by a mitochondrial biogenesis kit. Pretreatment with CoQ10 prevented the decreases of Akt, CREB, PGC-1α, and NRF2 and increased mitochondrial biogenesis. Conclusions: Taken together, these results describe a new mechanism of CoQ10-conveyed neuro-protection and indicate a central role for mitochondrial biogenesis in protecting against glutamate-induced excitotoxicity.
