Our Research

historic science photo from http://memory.loc.gov/ Our laboratory group is committed to identifying key molecular and developmental determinants of diabetes. To this end, our work is currently focused on three questions.

  • How does fetal exposure to high glucose incite poor metabolism? To study this, we have developed an innovative model of intrauterine diabetes exposure accomplished via unilateral infusion of macronutrients into the uterine artery.

  • How does cystic fibrosis cause diabetes? We are working collaboratively with other University of Iowa investigators to better understand the pathophysiology of cystic fibrosis related diabetes. Our work suggests that cystic fibrosis induces a functional pancreatic islet defect independent of structural pancreatic damage.

  • How can fatty acid metabolism be decoupled from insulin resistance? We recently demonstrated that PPARγ directly augments the PDK1:AKT nexus of insulin signaling despite directly increasing muscle fatty acid uptake.

Apr-2015 Dr. Kua receives a Fellow Research Award at the national Society for Pediatric Research meeting in San Diego.

Feb-2015 The PET center helped us determine that the placenta has immense avidity for glucose, supporting unparalleled rates of glucose flux, as published here and reviewed in The Journal of Nuclear Medicine 56(3):21N.

Jan-2015 We assisted Dr. Aliye Uc’s lab determine whether loss of porcine CFTR leads to diabetes, as published here.

Jan-2015 Dr. Jamal Kriem, a pediatric gastroenterology fellow, joins the laboratory.

Jul-2014 Dr. Michelle Baack, a neonatology fellow in the lab, has published her work showing that isolated hyperglycemia, localized only to the uterine artery, is sufficient to induce embryopathy.

Mar-2014 We assisted Dr. Jeff Segar describe the influence of fetal angiotensin II on fetal cardiac remodeling, as published here.
