Effects Of Muscle Cooling On Ampk And Protein Synthesis In Skeletal Muscle, Kyle Lyons, David Thomson, Pdbio
Journal of Undergraduate Research
AMP-activated protein kinase (AMPK) is an intracellular protein that regulates many signaling responses including the mechanistic target of rapamycin (mTOR) pathway, which increases protein synthesis1. Recent research suggests that cold-water immersion of the leg activates AMPK in skeletal muscle. It is not known whether cold directly activates AMPK in skeletal muscle or if the aforementioned results are due to systemic or hormonal responses. Furthermore, the direct effect of cooling on protein synthesis-related signaling in skeletal muscle has not been established. If cooling affects the activation of AMPK, then it could also affect mTOR. Therefore, the purpose of this study was …

Theses and Dissertations
Ad libitum high-fat diet (HFD)-induced obesity leads to insulin resistance in skeletal muscle, altered gene expression, and altered growth signaling, all of which contributes to pathological changes in metabolism. Liver kinase B1 (LKB1) is an important metabolism regulator. The purpose of this dissertation was to understand how knocking out LKB1 influences HFD induced adaptations in mouse skeletal muscle. To do so, control and skeletal muscle LKB1 knock-out (LKB1-KO) mice were put on either standard diet (STD) or HFD for 1 week or 14 weeks, or put on the HFD for 14 weeks and then switched to STD for 1 week …
