Conjugated linoleic acid (CLA) isomers have a number of beneficial health effects, as shown in biomedical studies with animal models. Previously, we reported that a mixture of CLA isomers improved… (More)

Repetitive stimulation potentiates contractile tension of fast-twitch skeletal muscle. We examined the role of myosin regulatory light chain (RLC) phosphorylation in this physiological response by… (More)
Growing evidence suggests that activation of mitogen-activated protein kinase (MAPK) signal transduction mediates changes in muscle gene expression in response to exercise. Nevertheless, little is… (More)
To determine the role of GLUT4 on postexercise glucose transport and glycogen resynthesis in skeletal muscle, GLUT4-deficient and wild-type mice were studied after a 3 h swim exercise. In wild-type… (More)
Phosphorylation of the alpha-subunits of Na(+),K(+)-adenosine triphosphatase in response to insulin, high extracellular glucose concentration, and phorbol 12-myristate 13-acetate was investigated in… (More)

Level of physical activity is linked to improved glucose homeostasis. We determined whether exercise alters the expression and/or activity of proteins involved in insulin-signal transduction in… (More)
We determined the muscle fiber type-specific response of intracellular signaling proteins to insulin. Epitrochlearis (Epi; 15% type I, 20% type IIa, and 65% type IIb), soleus (84, 16, and 0%), and… (More)
Repetitive low frequency stimulation results in potentiation of twitch force development in fast-twitch skeletal muscle due to myosin regulatory light chain (RLC) phosphorylation by Ca(2+)/calmodulin… (More)
Cell surface GLUT4 levels in skeletal muscle from nine type 2 diabetic subjects and nine healthy control subjects have been assessed by a new technique that involves the use of a biotinylated… (More)
