In brief…

Our Research

Our team is committed to identifying key molecular and developmental determinants of diabetes, with the ultimate goal of preventing this disease. To this end, our work is currently focused on two questions.

  • What are the mechanisms by which early life adverse conditions increase diabetes risk? To study this, we have developed an innovative model of intrauterine diabetes exposure accomplished via unilateral infusion of macronutrients into the uterine artery. We have recently described that long-lasting skeletal muscle insulin resistance begins within hours of such exposure.
  • 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 demonstrates that cystic fibrosis induces a functional pancreatic islet defect. Ongoing studies aim to understand the mechanistic origins of impaired islet function.

Electromagnetic Fields Can Treat Type 2 Diabetes

Our lab contributed to scientific work newly published in Cell Metabolism showing that exposure to generated electromagnetic fields lowers blood sugar in rodents with type 2 diabetes. We were thrilled to help design and interpret the glycemic clamps that were used to better understand the physiological mechanisms involved in the phenomenon. (Pubmed link; DOI link).

A Tale of Two Pancreases

We contributed to a review just published in Diabetologia. The article reviews how diseases of the exocrine pancreas can lead to defects in insulin production and diabetes. (Pubmed link, DOI link)

Developmental origins of endocrine disease

The environment each of us was exposed early in life, even in the womb, matters for our long term health. The mechanisms involved are not well understood, but the impacts include endocrine diseases – especially diabetes. Check this out: the Journal of Endocrinology is publishing a special edition focused on the developmental origins of endocrine …

Gulnara Novbatova completes Masters of Science degree

Congratulations to Gulnara Novbatova. Today, she presented her Master’s research performed in our lab. Her work identified differential auxologic effects of maternal high fat diet on offspring between strains. She has now completed her Masters of Science requirements. We wish her the best of luck as she moves to start her Doctoral work.

New Website is Up

We are pleased to unveil our new lab website, as of 1:12 pm CDT on April 17, 2019.  We were very fond of the old site, but time had antiquated its server, operating system, and rendering engine.  We have moved much of the content on to the new website, and hope to better keep up with …
