Ampk Activation: A Therapeutic Target For Type 2 Diabetes?, Kimberly A. Coughlan, Rudy Valentine, Neil B. Ruderman, Asish K. Saha

Rudy Valentine

Type 2 diabetes (T2D) is a metabolic disease characterized by insulin resistance, β-cell dysfunction, and elevated hepatic glucose output. Over 350 million people worldwide have T2D, and the International Diabetes Federation projects that this number will increase to nearly 600 million by 2035. There is a great need for more effective treatments for maintaining glucose homeostasis and improving insulin sensitivity. AMP-activated protein kinase (AMPK) is an evolutionarily conserved serine/threonine kinase whose activation elicits insulin-sensitizing
effects, making it an ideal therapeutic target for T2D. AMPK is an energy-sensing enzyme that is activated when cellular energy levels are low, and it signals …

Lean And Obese Zucker Rats Exhibit Different Patterns Of P70s6 Kinase Regulation In The Tibialis Anterior Muscle In Response To High-Force Muscle Contraction, Anjaiah Katta, Sunil K. Karkala, Miaozong Wu, Sarath Meduru, Devashish H. Desai, Kevin M. Rice, Eric R. Blough May 2013

Lean And Obese Zucker Rats Exhibit Different Patterns Of P70s6 Kinase Regulation In The Tibialis Anterior Muscle In Response To High-Force Muscle Contraction, Anjaiah Katta, Sunil K. Karkala, Miaozong Wu, Sarath Meduru, Devashish H. Desai, Kevin M. Rice, Eric R. Blough

Increased phosphorylation of the 70-kDa ribosomal S6 kinase (p70S6k) signaling is strongly correlated with the degree of muscle adaptation following exercise. Herein we compare the phosphorylation of p70S6k, Akt, and mammalian target of rapamycin (mTOR) in the tibialis anterior (TA) muscles of lean and obese Zucker rats following a bout of eccentric exercise. Exercise increased p70S6k (Thr389) phosphorylation immediately after (33.3 ± 7.2%) and during [1 h (24.0 ± 14.9%) and 3 h (24.6 ± 11.3%)] recovery in the lean TA and at 3 h (33.5 ± 8.0%) in the obese TA Zucker rats. mTOR (Ser2448) phosphorylation was elevated in …
