Role of AMP-activated protein kinase in mechanism of metformin action.
Metformin is a widely used drug for treatment of type 2 diabetes with no defined cellular mechanism of action. Its glucose-lowering effect results from decreased hepatic glucose production andExpand

Pioglitazone for diabetes prevention in impaired glucose tolerance.
BACKGROUND Impaired glucose tolerance is associated with increased rates of cardiovascular disease and conversion to type 2 diabetes mellitus. Interventions that may prevent or delay such occurrencesExpand

AMP-activated protein kinase (AMPK) is activated in muscle of subjects with type 2 diabetes during exercise.
Insulin-stimulated GLUT4 translocation is impaired in people with type 2 diabetes. In contrast, exercise results in a normal increase in GLUT4 translocation and glucose uptake in these patients.Expand

Metformin increases AMP-activated protein kinase activity in skeletal muscle of subjects with type 2 diabetes.
Metformin is an effective hypoglycemic drug that lowers blood glucose concentrations by decreasing hepatic glucose production and increasing glucose disposal in skeletal muscle; however, theExpand

Increased Adenosine Monophosphate–Activated Protein Kinase Activity in Rat Hearts With Pressure-Overload Hypertrophy
Background—Recent reports suggest that activation of adenosine monophosphate (AMP)–activated protein kinase (AMPK), in response to acute changes in cellular energy status in cardiac and skeletalExpand

AMP-activated protein kinase activity and glucose uptake in rat skeletal muscle.
The AMP-activated protein kinase (AMPK) has been hypothesized to mediate contraction and 5-aminoimidazole-4-carboxamide 1-beta-D-ribonucleoside (AICAR)-induced increases in glucose uptake in skeletalExpand

Elevated Toll-Like Receptor 4 Expression and Signaling in Muscle From Insulin-Resistant Subjects
OBJECTIVE— Tall-like receptor (TLR)4 has been implicated in the pathogenesis of free fatty acid (FFA)-induced insulin resistance by activating inflammatory pathways, including inhibitor of κBExpand

Effect of Acute Exercise on AMPK Signaling in Skeletal Muscle of Subjects With Type 2 Diabetes
Activation of AMP-activated protein kinase (AMPK) by exercise induces several cellular processes in muscle. Exercise activation of AMPK is unaffected in lean (BMI ∼25 kg/m2) subjects with type 2Expand

LKB1-AMPK signaling in muscle from obese insulin-resistant Zucker rats and effects of training.
AMPK is a key regulator of fat and carbohydrate metabolism. It has been postulated that defects in AMPK signaling could be responsible for some of the metabolic abnormalities of type 2 diabetes. InExpand

A role for AMP-activated protein kinase in diabetes-induced renal hypertrophy.
We tested the hypothesis that AMP-activated protein kinase (AMPK), an energy sensor, regulates diabetes-induced renal hypertrophy. In kidney glomerular epithelial cells, high glucose (30 mM), but notExpand
