Lifelong restriction of dietary valine has sex-specific benefits for health and lifespan in mice

Mariah F. Calubag, Ismail Ademi, Cara L. Green, Dulmalika N. H. Manchanayake et autres

Dietary protein is a key regulator of metabolic health in humans and rodents. Many of the benefits of protein restriction are mediated by reduced intake of dietary branched-chain amino acids (leucine, valine and isoleucine) and restriction of the branched-chain amino acids is …

Glutamine Metabolism Supports α cell Mass and Glucagon Secretion

Anna Marie R Schornack, Tyler J. Rodgers, Matthew Shou, Walter Siv et autres

The liver-α cell axis is a finely tuned biological rheostat that regulates whole body amino acid availability. Pancreatic α cells secrete glucagon that regulates amino acid catabolism through gluconeogenesis and ureagenesis, yet the mechanisms linking amino acid levels to α cell growth …

Pancreatic islet α cell function and proliferation require the arginine transporter SLC7A2

Erick Spears, Jade E. Stanley, Matthew Shou, Linlin Yin et autres

Interrupting glucagon signaling decreases gluconeogenesis and the fractional extraction of amino acids by liver from blood, resulting in lower glycemia. The resulting hyperaminoacidemia stimulates α cell proliferation and glucagon secretion via a liver/α cell axis. We hypothesized that α cells detect and …

AttieLab-QTL-Viewer: Interactive Shiny App for Diversity Outbred Mouse QTL Analysis

Kalynn Willis, Charles Opara, Brian S. Yandell, Chris Emfinger et autres

The AttieLab-QTL-Viewer is a modular R/Shiny web application for exploring quantitative trait loci in Diversity Outbred mouse data. It provides access to genome-wide RNA expression data from the livers of 1200 DO samples, as reported in Opara et al. (See preprint information). …

Proinsulin regulators identified with CRISPR screen and in vivo mouse QTL mapping

Sisi Lai, Mark P. Keller, Jinglin Zhang, Zhou Fang et autres

Altered proinsulin levels in β-cells and bloodstream are hallmarks of diabetes and other diseases, but our knowledge about the proinsulin regulators remains limited. Here we perform a genome-wide CRISPR screen to identify 84 proinsulin regulators that alter intracellular proinsulin/insulin ratio in a …

Restriction of Individual Branched‐Chain Amino Acids has Distinct Effects on the Development and Progression of Alzheimer's Disease in 3xTg Mice

Reji Babygirija, Cara L. Green, Michelle M. Sonsalla, Izabelle Marie F. Le et autres

Dietary protein regulates metabolic health and aging, with many benefits of a low protein diet resulting from reduced consumption of the three branched-chain amino acids (BCAAs), leucine, isoleucine, and valine. Each BCAA has distinct physiological and molecular effects, and while restriction of …

Distinct genetic architectures of mRNA expression and splicing QTL in the Diversity Outbred mouse population

C. Opara, Kelly A. Mitok, Christopher H. Emfinger, Katheryn L Schueler et autres

Abstract Genetic association studies of mRNA abundance phenotypes link regulatory gene loci to mRNA abundance (quantitative trait loci; QTL). Here, we used liver RNA-seq data from a large cohort of the Diversity Outbred (DO) mouse population to map QTL for gene abundance …

Mammals that can develop type 2 diabetes have a similarly structured β-sheet amyloid oligomer

Brynn E. LeMasters, Caitlyn R. Fields, Justin P. Lomont, Farzaneh Chalyavi et autres

S. Using two-dimensional infrared spectroscopy, we monitor the structure of IAPP from seven different mammals, five of which are from species that can develop type 2 diabetes (ferret, raccoon, cat, baboon, and human) and three from those that do not (hamster, rat, …

A structural model of toxic amyloid oligomers involved in type 2 diabetes

Shivani T. Shivani, Brynn E. LeMasters, Thirupathi Ravula, Harrison J. Esterly et autres

Amyloid oligomers of the human islet amyloid polypeptide (hIAPP) are a likely cytotoxic species driving β-cell death in type 2 diabetes, but their transient nature has precluded atomic-level structural characterization. We obtained a high-resolution structure of a physiologically relevant hIAPP oligomer. Using …

Modeling metabolic disease susceptibility and resilience in genetically diverse mice

Candice N. Baker, Jeffrey M. Harder, Daniel A. Skelly, Isabela Gerdes Gyuricza et autres

Summary Model organisms have provided critical insights into the basic biology of metabolic disorders, however, one of the greatest limitations to translation has been the absence of the genetic heterogeneity that is characteristic of human populations. We examined metabolic health across three …
