Current Research Interest

  • MOLECULAR METABOLISM, the concept of it has had a makeover from what we used to perceive some time ago. As biological sciences continue to expand the horizons of its knowledge domains, it is becoming manifest that metabolism is at the centre of all the cellular processes both in physiology and in pathophysiology. At the Metabolic Diseases Laboratory we put effort in understanding the molecular basis of human disorders through the scope of metabolism. To this end we work with genes, proteins, cells, mice and human patients.
    Currently we are working on several broad aspects in the plethora of Metabolic Disorders –

    We have identified ubiquitin-proteasome system as novel regulator of hepatic fat turnover. We showed that ubiquitin ligase COP1 promotes NAFLD by targeting adipose triglyceride lipase (ATGL) for proteasomal degradation. In liver, ATGL serves as a major triacylglycerol lipase and controls bulk of intracellular lipid turnover. COP1 thus controls hepatocyte fat content, fatty acid mobilization and oxidation, the metabolic outcomes that require ATGL. Depleting COP1 gene in mice with NAFLD significantly reduced disease burden.

  • Mitochondrial metabolism: Crosstalk between nutrients and muscle aging

Burn more fat to make your muscles younger: Our study show implications that in age associated muscle frailty, the PPARa-ATGL axis could partially maintain the muscle mitochondrial metabolism (which otherwise declines with age).

  • Metabolic reprogramming in cancer

Latest research from MDL has shown that cancer cells in order to sustain high proliferative rates inhibit glucose production particularly of tissues were the gluconeogenic program is active like liver and kidney tissues.

  • Pathophysiology of Indian type 2 diabetes (T2DM)

    We took multi pronged approaches in investigating T2DM in Indian patients with an emphasis on incretin pathway. Intestinal mucosa produces certain factors named incretin peptides such as glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) which have the capacity to reduce blood glucose level by directly acting on the pancreatic beta cells. We have found that the negative regulator of incretin peptides, dipeptidyl peptidase-4 (DPP4) plays a critical role in the pathogenesis of T2DM in Indian patients.
