The Mirmira LabUnderstanding the β cell in Diabetes
Diabetes is reaching epidemic proportions in the USA. A recent analysis revealed that the prevalence of pre-diabetes and diabetes in the US is in excess of 50%. Both major forms of diabetes, type 2 (T2D) and type 1 (T1D), are increasing in incidence in the USA. Similarly, it is becoming increasingly apparent that both forms of diabetes share cellular pathogeneses, where dysfunction and/or death of islet β cells is a common denominator. To that end, the Mirmira Lab is focused on understanding the specific role of the β cell during the pathogenesis of diabetes. Our laboratory has been focused on diabetes research for the past 20 years. Our lab has been host to high school students, undergraduates, graduate students, and postdoctoral scholars over these years, and more 50 people have trained in our lab and have gone on to careers as scientists, physicians, and educators. You can learn about our research and the members of our laboratory on this website. If you want to learn more about our lab and the research, contact us.

12/15-lipoxygenase catalyzes the oxygenation of fatty acids to produce lipid pro-inflammatory mediators, the primary being 12-HETE. One of our initial studies showed that the deletion of 12/15-lipoxygenase in the pancreas is sufficient to protect against obesity-induced glucose intolerance, via a mechanism involving Nrf2-mediated activation of antioxidant genes (Tersey et al. MCB 2014).
Pancreatic β cell proliferation is significantly reduced in adults. Interestingly, during the early phases of diabetes, the proliferative capacity of the β cells is increased, possibly for adapting to the increased insulin demand. Our lab has previously shown that the translation factor eIF5A acts as a sensor that catalyses the translation of mRNAs involved in cellular replication.
Type 1 diabetes (T1D) is a complex and heterogenous disease. Insulin-producing β cells are the target of destruction by the immune system, and those who display autoantibodies against β cell antigens are at highest risk for developing the disease. Development of autoantibodies is a relatively late event in the pathogenesis of the disease, and recent studies using immune-suppressive agents in these individuals delays the onset of diabetes, but does not prevent it
Flat Stanley visits The Mirmira Lab
The Mirmira Lab hosted a Flat Stanley from Ms. Melody Gayle’s second grade class at Waldron Elementary School in Shelby County, Indiana.
We hope that our Stanley was able to see that Science is F-U-N and we hope that his adventures with us inspires other young, curious minds to explore what a future career in STEM could look like!
