- Abstract
- Activation of peroxisome proliferator-activated receptors (PPARs) plays a crucial role in cellular energy metabolism that directly impacts mitochondrial biogenesis. In this study, we demonstrate that syringaresinol, a pharmacological lignan extracted from Panax ginseng berry, moderately binds to and activates PPAR beta with K-D and EC50 values of 27.62 +/- 15.76 mu M and 18.11 +/- 4.77 mu M, respectively. Subsequently, the expression of peroxisome proliferator-activated receptor gamma coactivator-1 alpha together with PPAR beta transcriptional targets, mitochondrial carnitine palmitoyltransferase 1 and uncoupling protein 2, was also enhanced in terms of both mRNA and protein levels. The activation of these proteins induced mitochondrial biogenesis by enrichment of mitochondrial replication and density within C2C12 myotubes. Importantly, knockdown of PPAR beta reduced the syringaresinol-induced protein expression followed by the significant reduction of mitochondrial biogenesis. Taken together, our results indicate that syringaresinol induces mitochondrial biogenesis by activating PPAR beta pathway. (C) 2016 Elsevier Ltd. All rights reserved.
