IIT Mandi discovers potential drug to reverse some cases of Type 2 diabetes

New Delhi :
Researchers of Indian Institute of Technology, Mandi (IIT Mandi) has discovered a potential drug to reverse some cases of Type 2 Diabetes. Insulin, a hormone produced by the pancreas, is used by cells to absorb glucose from the blood. Type-2 Diabetes results when cells lose their ability to use insulin due to a variety of reasons.

Researchers identified a critical protein molecule –

“We’ve known that one of the causes of insulin resistance is inflammation”, says Dr Mondal, “We wanted to find out if and how hyperinsulinemia invokes inflammation in the body, which would provide the link between the two conditions”. The researchers identified a critical protein molecule – SIRT1 which is repressed in hyperinsulinemia.  They discovered that a decrease in SIRT1 activates another protein called NFkB, which instigates inflammation, thus providing the link between hyperinsulinemia and systemic inflammation.

Significance of this discovery is enormous –

The team has also discovered a solution to this problem. The researchers found that low-dose naltrexone (LDN), a drug commonly administered for opiate addiction, can activate SIRT1, thereby reducing inflammation and increasing insulin sensitivity of cells. The significance of this discovery is enormous. “Naltrexone at low doses could potentially restore some of the diabetes-associated events in cellular and animal models”, says Dr Mondal, who is confident that this is a viable path to follow for Type-2 diabetes management.

Research team intends to study –

Naltrexone is already an FDA-approved drug that is used for the treatment of opioid addiction and can easily be repurposed for inflammation reduction and diabetes control. The research team intends to study this thread further, to understand the mechanistic aspects of LDN’s effects on hyperinsulinemia-induced inflammation and resulting insulin resistance.

Understand the various causative factors –

The study by the IIT Mandi researchers and its collaborators is timely given the urgent need to understand and address the issue of diabetes in India. “India is the diabetes capital of the world”, says, Dr Mondal of IIT Mandi, adding that one of every six diabetics in the world is Indian.  “It is important to understand the various causative factors for diabetes to find cures and management strategies”, says the lead researcher, whose work seeks to understand and treat insulin resistance.

Authored by the lead scientist on this research –

The paper has been authored by the lead scientist on this research Dr Prosenjit Mondal, Associate Professor, School of Basic Sciences, IIT Mandi, and Co-investigators on the study were research scholars, Abhinav Choubey, Ms.Khyati Girdhar of IIT Mandi along with Dr Debabrata Ghosh, Aditya K Kar, and Shaivya Kushwaha of CSIR-IITR, Lucknow and Dr Manoj Kumar Yadav of SRM University, Delhi-NCR, Sonipat, Haryana.

Research work that was funded by –

The results of the research work that was funded by the Science and Engineering Research Board (SERB) grant, have recently been published in the Journal of Biological Chemistry. Diabetes is a common disease in India & this research will help in providing aid to people suffering from the disease.
