Research Focus of the Lab:

The broad research focus of my laboratory is on different aspects of lipid and tumor metabolism. Specifically, we are trying to understand the functionalcorrelates of the athero-protective lipoprotein molecule, High Density Lipoprotein and its different components in coronary artery disease.  Recent evidence calls for a re-evaluation of the classical measure of HDL function for estimating its protective effect which is HDL cholesterol. Our research is aimed at assessing the measure of HDL’s functionwith respect to its key physiological roles i.e. in reverse cholesterol transport, antioxidative capacity, endothelial reactivity etc. We also want to analyse and understand the implications of  changes in the quality of the different molecules on  HDL that are necessary for these functions such as ApoA1, the HDL associated enzyme paraoxonase,and Sphingosine-1-phosphate.In the context of regulation intracellular lipid metabolism, some of our work is exploring the role of ABCA1 in maintaining adipocyte homeostasis in obesity since we have found lower expression of this transporter in the visceral adipose tissue of obese individuals. Our cancer research involves an attempt to grasp the relevance of alterations in mitochondrial DNA to leukemia metabolism. Our goal is to analyse the effect of changes in quantitative content of mitochondrial DNA on leukemia tumorigenesis, and possibly, reprogramming the metabolic state of the tumor cells. Our work involves the analysis of mitochondrial copy number, its regulation, relevance to intra-tumor heterogeneity and possible ramifications for mitochondrial biogenesis, bioenergetics and metabolism in pediatricleukemia.  I also engage in  public health nutrition research in the context of dietary quality and nutritional status of indigenous tribal communities and theconsumption of indigenous foods available from the unique agroforestry environment accessible to them and am a collaborator on a Wellcome Trust/DBT India Alliance fellowship on this theme.

We have a vibrant and enthusiastic team in the lab that is always looking to enhance their academic and extra-curricular skills.
