Objectives: The all anti-obesity drugs currently approved by the US Food and Drug Administration work by reducing energy intake. In fact, no approved drug targets energy expenditure. In Korean medicine, it is known to Qi or Yang invigorating therapy could increase energy metabolism. Aconitum carmichaeli Debx (ACD) is a Yang invigorating herb, often used for treat obesity in Korean medicine. In the present study, the authors investigated the regulatory effects of ACD in energy metabolism and mitochondrial biogenesis in C2C12 skeletal muscle cells.
Methods: The water extract of ACD (0.2, 0.5 and 1.0 mg/ml) were treated in differentiated C2C12 cells. The protein or mRNA levels of target genes were analyzed and mitochondrial mass were investigated.
Results: ACD activated the expressions of peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), nuclear respiratory factor 1 and TFAM and increased mitochondrial mass. ACD also increased adenosin monophosphate-activated protein kinase (AMPK), and acetyl-CoA carboxylase.
Conclusions: This study suggests that ACD has the potential to increase energy metabolism and mitochondrial biogenesis by activating AMPK and PGC1α.
