Compartmentalization of GABA synthesis by GAD67 differs between pancreatic beta cells and neurons

Steinunn Baekkeskov Hanahan, Chiara Cianciaruso, Miriella Carmela Pasquier, Edward Allen Phelps

The inhibitory neurotransmitter GABA is synthesized by the enzyme glutamic acid decarboxylase (GAD) in neurons and in pancreatic β-cells in islets of Langerhans where it functions as a paracrine and autocrine signaling molecule regulating the function of i ...

Hepatic glucose sensing is required to preserve β cell glucose competence

Rolf Gruetter, Bernard Lanz, Frédéric Schütz, Carole Poitry-Yamate

Liver glucose metabolism plays a central role in glucose homeostasis and may also regulate feeding and energy expenditure. Here we assessed the impact of glucose transporter 2 (Glut2) gene inactivation in adult mouse liver (LG2KO mice). Loss of Glut2 suppr ...

Engineered insulin-like growth factor-1 for improved smooth muscle regeneration

Peter Frey, Jeffrey Alan Hubbell, Kristen Lorentz, Lirong Yang

Insulin-like growth factor-1 (IGF-1) has been shown to induce potent mitogenic responses in various cell types, yet its sustained local delivery is still an underdeveloped domain in the clinic. We report here an engineered IGF-1 that facilitates extended l ...

GLUT2-/- mice are resistant to age-induced accumulation of fat in the liver – an in vivo MRS study

Rolf Gruetter, Hongxia Lei, Ana Francisca Leal Silva Soares

Introduction: Whole-body energy balance is strongly dependent on the hepatic handling of metabolic fuels, which is affected by the hepatic lipid content (HLC). With in vivo nuclear magnetic resonance spectroscopy (MRS) HLC can be measured non-invasively an ...

Immune Engineering Via Differential Antigen Carriers and Co-Stimulatory Molecules

Jackson Eby

There is an increasing clinical need for vaccines capable of enhancing antigen-specific immune responses and treatments that can induce immunological tolerance toward a single antigen. Here we explore two platforms to enhance either immunization or toleriz ...

Adipocyte NCoR Knockout Decreases PPARγ Phosphorylation and Enhances PPARγ Activity and Insulin Sensitivity

Johan Auwerx, Hiroyasu Yamamoto

Insulin resistance, tissue inflammation, and adipose tissue dysfunction are features of obesity and Type 2 diabetes. We generated adipocyte-specific Nuclear Receptor Corepressor (NCoR) knockout (AKO) mice to investigate the function of NCoR in adipocyte bi ...

AMPK regulates energy expenditure by modulating NAD(+) metabolism and SIRT1 activity

Johan Auwerx, Carlos Canto Alvarez, Lilia Noriega Lopez

AMP-activated protein kinase (AMPK) is a metabolic fuel gauge conserved along the evolutionary scale in eukaryotes that senses changes in the intracellular AMP/ATP ratio. Recent evidence indicated an important role for AMPK in the therapeutic benefits of m ...

Notch-induced T cell development requires phosphoinositide-dependent kinase 1

Freddy Radtke

Phosphoinositide-dependent kinase l (PDK1) phosphorylates and activates multiple AGC serine kinases, including protein kinase B (PKB), p70Ribosomal S6 kinase (S6K) and p90Ribosomal S6 kinase (RSK). PDK1 is required for thymocyte differentiation and prolife ...

Activation of peroxisome proliferator-activated receptor delta induces fatty acid beta-oxidation in skeletal muscle and attenuates metabolic syndrome

Johan Auwerx

In this study, we defined the role of peroxisome proliferator-activated receptor beta/delta (PPARdelta) in metabolic homeostasis by using subtype selective agonists. Analysis of rat L6 myotubes treated with the PPARdelta subtype-selective agonist, GW501516 ...

In vivo measurements of brain glucose transport using the reversible michaelis-menten model and simultaneous measurements of cerebral blood flow changes during hypoglycemia

Rolf Gruetter

Glucose is the major substrate that sustains normal brain function. When the brain glucose concentration approaches zero, glucose transport across the blood-brain barrier becomes rate limiting for metabolism during, for example, increased metabolic activit ...
