Abstract:
Da-Bu-Yin-Wan (DBYW), a historically traditional Chinese medicine formula, was originally defined over 600 years ago. In recent decades, DBYW was clinically employed to treat Parkinson's disease (PD). To explore the underlying mechanism of DBYW on mitochondrial function, we investigated the effect of DBYW on mitochondrial function from the perspectives of DJ-1 and Akt signaling. Human derived neuroblastoma SH-SY5Y cells were transiently transfected with the plasmid pcDNA3-Flag-DJ-1 aimed to overexpress the DJ-1 protein. Transfected cells were treated with 1-methyl-4-phenylpyridinium (MPP(+)), a PD-related mitochondrial complex I inhibitor, in the absence and presence of DBYW. The cell viability was assessed by Cell Counting Kit-8 assay. The protein expressions of DJ-1 and Akt signaling were examined by western blotting. The mitochondrial mass was evaluated by confocal fluorescence microscopy. The mitochondrial complex I activity and cellular ATP content were measured by commercial kits. Transfection with pcDNA3-Flag-DJ-1 decreased the MPP(+)-induced toxicity and overexpressed the DJ-1. In DJ-1 overexpressed cells, the mitochondrial mass was raised, mitochondrial complex I activity was improved, and cellular ATP content was increased. In addition, overexpression of DJ-1 augmented the Akt phosphorylation on threonine 308 and serine 473. Moreover, DBYW promoted the above effects in DJ-1 expressed cells. These data suggest that DJ-1 protects the mitochondrial function by medicating Akt phosphorylation in MPP(+)-treated SH-SY5Y cells. Moreover, DBYW enhances the protective effect of DJ-1 medicated Akt phosphorylation on mitochondrial function.
