Resumen:
Peroxisome proliferator-activated receptor ß/d (PPARß/d) activates AMP-activated protein kinase (AMPK) and plays a crucial role in glucose and lipid metabolism. Here, we examine whether PPARß/d activation effects depend on growth differentiation factor 15 (GDF15), a stress response cytokine that regulates energy metabolism. Pharmacological PPARß/d activation increases GDF15 levels and ameliorates glucose intolerance, fatty acid oxidation, endoplasmic reticulum stress, and inflammation, and activates AMPK in HFD-fed mice, whereas these effects are abrogated by the injection of a GDF15 neutralizing antibody and in Gdf15(-/-) mice. The AMPK-p53 pathway is involved in the PPARß/d-mediated increase in GDF15, which in turn activates again AMPK. Consistently, Gdf15(-/-) mice show reduced AMPK activation in skeletal muscle, whereas GDF15 administration results in AMPK activation in this organ. Collectively, these data reveal a mechanism by which PPARß/d activation increases GDF15 levels via AMPK and p53, which in turn mediates the metabolic effects of PPARß/d by sustaining AMPK activation.
