Chronic Amp-Activated Protein Kinase Activation And A High-Fat Diet Have An Additive Effect On Mitochondria In Rat Skeletal Muscle, Natasha Fillmore

Theses and Dissertations

Factors that stimulate mitochondrial biogenesis in skeletal muscle include AMPK, calcium, and circulating FFAs. Chronic treatment with either AICAR, a chemical activator of AMPK, or increasing circulating FFAs with a high fat diet increases mitochondria in rat skeletal muscle. The purpose of this study was to determine whether the combination of chronic chemical activation of AMPK and high fat feeding would have an additive effect on skeletal muscle mitochondria levels. We treated Wistar male rats with a high fat diet (HF), AICAR injections (AICAR), or a high fat diet and AICAR injections (HF+AICAR) for six weeks. At the end of …
