Journal ArticleDOI
Role of AMP-activated protein kinase in mechanism of metformin action
Gaochao Zhou,Robert W. Myers,Ying Li,Yuli Chen,Xiaolan Shen,Judy Fenyk-Melody,Margaret Wu,John Ventre,Thomas W. Doebber,Nobuharu Fujii,Nicolas Musi,Michael F. Hirshman,Laurie J. Goodyear,David E. Moller +13 more
TL;DR: It is reported that metformin activates AMPK in hepatocytes; as a result, acetyl-CoA carboxylase (ACC) activity is reduced, fatty acid oxidation is induced, and expression of lipogenic enzymes is suppressed.
Journal ArticleDOI
Complex Distribution, Not Absolute Amount of Adiponectin, Correlates with Thiazolidinedione-mediated Improvement in Insulin Sensitivity
Utpal B. Pajvani,Meredith Hawkins,Terry P. Combs,Michael W. Rajala,Tom Doebber,Joel P. Berger,John A. Wagner,Margaret Wu,Annemie Knopps,Anny H. Xiang,Kristina M. Utzschneider,Steven E. Kahn,Jerrold M. Olefsky,Thomas A. Buchanan,Philipp E. Scherer +14 more
TL;DR: It is demonstrated that changes in SA in a number of type 2 diabetic cohorts serve as a quantitative indicator of improvements in insulin sensitivity obtained during TZD treatment, whereas changes in total serum adiponectin levels do not correlate well at the individual level.
Journal ArticleDOI
Novel Peroxisome Proliferator-activated Receptor (PPAR) γ and PPARδ Ligands Produce Distinct Biological Effects
Joel Berger,Mark D. Leibowitz,Thomas W. Doebber,Alex Elbrecht,Bei Zhang,Gaochou Zhou,Chhabi Biswas,Catherine A. Cullinan,Nancy S. Hayes,Ying Li,Michael R. Tanen,John Ventre,Margaret Wu,Gregory D. Berger,Ralph T. Mosley,Robert W. Marquis,Conrad Santini,Soumya P. Sahoo,Richard L. Tolman,Roy G. Smith,David E. Moller +20 more
TL;DR: Novel, non-thiazolidinedione agonists for PPARγ and PPARδ that were identified by radioligand binding assays improve hyperglycemia and hypertriglyceridemia in vivo and are able to potentiate preadipocyte differentiation.
Journal ArticleDOI
Prevention of obesity in mice by antisense oligonucleotide inhibitors of stearoyl-CoA desaturase-1
Guoqiang Jiang,Zhihua Li,Franklin Liu,Kenneth P. Ellsworth,Qing Dallas-Yang,Margaret Wu,John Ronan,Christine Esau,Cain Murphy,Deborah Szalkowski,Raynald Bergeron,Thomas W. Doebber,Bei B. Zhang +12 more
TL;DR: Prevention of diet-induced obesity with concomitant reductions in SCD1 expression and the ratio of oleate to stearoyl-CoA in tissues and plasma and pharmacological inhibition ofSCD1 represents a new target for the treatment of obesity and related metabolic disorders.
Journal ArticleDOI
Targeted Disruption of the Tumor Necrosis Factor-α Gene: Metabolic Consequences in Obese and Nonobese Mice
John Ventre,Thomas W. Doebber,Margaret Wu,Karen L. MacNaul,Karla Stevens,Manolis Pasparakis,George Kollias,David E. Moller +7 more
TL;DR: It is concluded that T NF-α functions to regulate plasma triglycerides and body adiposity and that although TNF-α contributes to reduced insulin sensitivity in older or obese mice, the absence of TNF -α is not sufficient to substantially protect against insulin resistance in the GTG hyperphagic model of rodent obesity.
