AMP kinase-induced skeletal muscle glucose but not long-chain fatty acid uptake is dependent on nitric oxideJane Shearer
Department of Molecular Physiology and Biophysics, 702 Light Hall, Vanderbilt University, Nashville, TN, 37232 0615, USA

5-Aminoimidazole-4-carboxamide-1-beta-D-ribofuranoside causes acute hepatic insulin resistance in vivoR Richard Pencek
Department of Molecular Physiology and Biophysics, Diabetes Research and Training Center, Vanderbilt University School of Medicine, Nashville, TN 37232 0615, USA
Diabetes 54:355-60. 2005..These findings have important implications for the targeting of AMP kinase for the treatment of insulin resistance, using AMP analogs...
AMPK stimulation increases LCFA but not glucose clearance in cardiac muscle in vivoJane Shearer
Dept. of Molecular Physiology and Biophysics, Vanderbilt University, Nashville, TN 37232-0615, USA
Am J Physiol Endocrinol Metab 287:E871-7. 2004..These results demonstrate that, in vivo, AMPK stimulation increases LCFA but not glucose clearance by a NOS-independent mechanism...
Glucose kinetics and exercise tolerance in mice lacking the GLUT4 glucose transporterPatrick T Fueger
Department of Molecular Physiology and Biophysics, Vanderbilt University School of Medicine, Nashville, TN 37232, USA
J Physiol 582:801-12. 2007..Finally, studies in GLUT4(-/-)HK(Tg) show that HK II improves exercise tolerance, independent of its effects on MGU...
Partial gene deletion of heart-type fatty acid-binding protein limits the severity of dietary-induced insulin resistanceJane Shearer
Department of Molecular Physiology and Biophysics, Vanderbilt University School of Medicine, Nashville, Tennessee, USA
Diabetes 54:3133-9. 2005..In conclusion, a partial reduction in H-FABP protein normalizes fasting glucose levels and improves whole-body insulin sensitivity in HFD-fed mice despite obesity...
Portal vein caffeine infusion enhances net hepatic glucose uptake during a glucose load in conscious dogsR Richard Pencek
Department of Molecular Physiology and Biophysics, Vanderbilt University School of Medicine, Nashville, TN 37232 0615, USA
J Nutr 134:3042-6. 2004..5 +/- 3.8 vs. 5.5 +/- 1.5 micromol/(kg . min)]. These findings indicate that physiologic circulating levels of caffeine can enhance NHGU during a glucose load, and the added glucose consumed by the liver is in part converted to lactate...
Heart-type fatty acid-binding protein reciprocally regulates glucose and fatty acid utilization during exerciseJane Shearer
Dept of Molecular Physiology and Biophysics, Vanderbilt University, 823 Light Hall, Nashville, TN 37232 0615, USA
Am J Physiol Endocrinol Metab 288:E292-7. 2005..These results show that, in vivo, H-FABP has reciprocal effects on glucose and LCFA utilization and whole body fuel homeostasis when metabolic demands are elevated by exercise...
Long chain fatty acid uptake in vivo: comparison of [125I]-BMIPP and [3H]-bromopalmitateJane Shearer
Department of Molecular Physiology and Biophysics, Vanderbilt University, Nashville, TN, USA
Lipids 43:703-11. 2008..Exercise preferentially exacerbates the breakdown of [3H]-BROMO, making [125I]-BMIPP the analogue of choice for prolonged (>30 min) experimental protocols with elevated metabolic demands...
Novel aspects of skeletal muscle glycogen and its regulation during rest and exerciseJane Shearer
Department of Molecular Physiology and Biophysics, Vanderbilt University, Nashville, TN, USA
Exerc Sport Sci Rev 32:120-6. 2004..These differences result in additional levels of regulation allowing granules to be regulated individually or regionally within the cell during both rest and exercise...
