During last two and a half decades our research interests have been to understand how protein kinases and phosphatases  mediated signal transduction regulate the molecular mechanism of insulin resistant diabetes. Our laboratory has contributed in deciphering the complex signal transduction cascades to elucidate the mechanism of regulation of insulin resistance in skeletal muscle cells and neuronal cells in vitro. Major highlights are:

1. A novel in vitro insulin resistant neuronal cell model developed to study insights into the signalling mechanisms in neuronal insulin resistance. The model is simple, relevant, cheaper than animal models and good for primary screening.

2. Our laboratory has provided one of the possible mechanisms of action of Metformin, the FDA approved drug for the treatment of insulin resistance, against peripheral insulin resistant diabetes.

3.Our laboratory has identified proteins like PTEN (a protein phosphatase), FAK (a protein kinase), Sirt2 (a deacetylase), and PAK (a protein kinase) and their regulatory roles in insulin-sensitive and –resistant signaling pathways in skeletal muscle and neuronal cells in vitro. These provides opportunities for future animal/clinical studies for drug discovery. Currently we are looking deeper into the interactions and functions of very critical insulin signalling proteins Akt, AS160, protein kinase C in regulating insulin resistant diabetes.

Leishmaniasis causes a geographically widespread diseases, called Leishmanasis. The Leishmania flagellum is a highly versatile organelle that exhibits intricate environment triggered responses. However, till date flagellar motility and its regulation in Leishmania remains poorly understood despite the importance in its survival and infectivity. In humans, defects in cilia cause a group of severe diseases called ciliopathies. Eukaryotic parasites like trypanosomes have served as attractive models for the study of such genetic defects in humans. However, there is no suitable model till date for the study of the signalling and regulatory mechanisms of ciliary motility in ciliopathies. In our laboratory, we have developed a demembranated ATP-reactivated model (LRP) for studying molecular mechanisms that regulate flagellar motility in Leishmania. Such a model allows the researcher complete control to manipulate the cell chemically and mechanically under controlled standardized conditions. We believe that reactivation of flagellar motility in demembranated Leishmania presents it as an attractive model for flagellar motility studies. Using our model we observed that cAMP, via protein kinase A mediates “wave reversal” of the flagellar waveform to a ciliary waveform which has been believed to have a role in tactic responses such as obstacle-avoidance, chemotaxis, osmotaxis etc. With this model we are also interested in elucidating the effects of other second messenger molecules, role of dynein ATPases in regulating the flagellar beat and waveform.
