In this study, we investigated effects of pine nut oil (PNO) on high-fat diet (HFD)-induced obesity and metabolic dysfunction in skeletal muscle and brown adipose tissue (BAT). Male C57BL/6 mice were fed an HFD with 15% energy from lard and 30% either from soybean oil (SBO-HFD) or PNO (PNO-HFD) for 12 weeks. The PNO-HFD resulted in less weight gain and intramuscular lipid accumulation than the SBO-HFD, and was accompanied by up-regulation of transcripts and proteins related to oxidative metabolism and phosphorylation of AMPK, as well as molecules selectively expressed in type I and type IIa muscle fibers. In addition, uncoupling protein-1 was upregulated in BAT. These beneficial metabolic effects were partly associated with the dual ligand activity of pinolenic acid, which is abundant in PNO, for peroxisome proliferator-activated receptors alpha and delta. Our findings suggest that PNO may have potential as a dietary supplement for counteracting obesity and metabolic dysregulation.
