UIC Bioresearchers Present Possible Alternative to Insulin Injections

Posted by Sam Asher on Thu, Jan 09, 2014

For many of the 366 million people around the world who have been diagnosed with type 2 diabetes, insulin injections are an unfortunate but often necessary routine. However, the most recent lab reports from the University of Illinois, Chicago show that in many people, the insulin they need is right inside their own cells, just waiting to be released.

For a little background, type 2 diabetes is caused by an excessive amount of glucose residing in the bloodstream. In healthy people, cells in the pancreas produce insulin, which lets glucose in the bloodstream enter cells. This is important because cells convert glucose into energy for the body. This is why insulin injections are prescribed: the insulin helps reduce the level of glucose in the bloodstream down to a healthy level. It is generally accepted that most people with type 2 diabetes simply don’t produce enough insulin.

Bellur S. Prabhakar (below), professor and head of microbiology and immunology at UIC, has been studying other possibilities. He and his team have been studying the genes of people with type 2 diabetes and noticed a common trend: the mutation or deactivation of the gene MADD. So they ran some experiments with mice whose MADD gene was disabled. Sure enough, the mice had abnormally high glucose levels in their bloodstream.

Curious about the reason behind these glucose spikes, Prabhakar examined the cells in the pancreas, expecting to see a deficiency in insulin. Instead, he found that “The cells were producing plenty of insulin, they just weren’t secreting it,” as he states in a UIC article. The missing gene was keeping the insulin inside the cells instead of out in the bloodstream where it was needed. As Prabhakar puts it, “Without the gene, insulin can’t leave the beta cells, and blood glucose levels are chronically high.”

Next up on Prabhakar’s to-do list is to develop a drug that releases the insulin from these cells so that insulin does not have to be injected into the body. “If this drug works to reverse the deficits associated with a defective MADD gene in the beta cells of our model mice, it may have potential for treating people with this mutation who have an insulin-secretion defect and/or type 2 diabetes.”

The 122,000 square foot building will offer primary care, urgent care, specialist services, and an on-site laboratory all under one roof. This was funded in part by a $12 million grant awarded to UIC under the Affordable Care Act. To obtain more detailed information regarding funding, research, and development at UIC, read Biotechnology Calendar’s complimentary University of Illinois, Chicago Funding and Vendor Statistics report.
