Research Area

Primary interests are Skin and Liver Biology.
Skin Biology:
The major research focus of our lab is skin photo-damage (Photo-carcinogenesis and Photo-aging), melanogenesis and melanoma. Solar UV radiation is known to elicit plenitude of events which culminates in skin photodamage. This lab studies major events responsible for initiating UVB induced photo-aging and skin cancer. The process of photo-aging is associated with alterations in extracellular matrix (ECM) and involves skin cells, such as keratinocytes, fibroblasts and infiltrating neutrophils. This lab studies the cellular, biochemical and molecular basis of UVB-induced photo-aging, along with the identification of target based potent therapeutic agents. Melanoma, a cancer of melanocytes, is arguably one of the most lethal and therapeutically resistant forms of skin cancer. This lab studies how melanoma and other skin cells interact with natural products, respond to UVB–irradiation and maintain cellular homeostasis. Melanogenesis, a highly complex process of melanin biosynthesis, is one of the most visible physiological responses of skin to UV exposure. Despite certain contradictory goals, an even skin tone is ideal of human beauty and depends on melanogenesis, among other factors.  This lab also focuses on the mechanistic analysis of novel molecules that modulate melanogenesis for achieving therapeutically and cosmetically useful outcomes. A salient feature of UVB-irradiation is generation of reactive oxygen species (ROS) and simultaneous modulation of ER stress, autophagy and apoptosis. This lab is particularly interesting in understanding the mechanistic basis for the UVB induced ROS generation, ER stress, autophagy and apoptosis in skin cells

Liver Biology:
In liver biology we wish to understand the pathophysiology/pathogenesis of Non-alcoholic fatty liver disease and develop therapeutic interventions using novel approaches.
Liver is the major player in the regulation of fat metabolism as it integrates endogenous and exogenous fatty acids. Any defect/perturbation in the liver fat metabolism potentially impacts the functioning of the liver. Lipotoxicity is one such condition which arises due to the perturbed or defective fat metabolism in liver. It starts with the accumulation of fat in the liver, which underlies spectrum of conditions known as Non-alcoholic fatty liver disease (NAFLD). Prevalence of non-alcoholic fatty liver disease (NAFLD) has been on an inclined trajectory with the rise in obesity and has been found to be affecting about 50% of individuals in some populations. Non alcoholic steatohepatitis (NASH), an advanced stage of NAFLD, has emerged as third most common cause of liver transplantation. NAFLD can progress to cirrhosis and liver failure in 3% to 15% cases and there have been emerging reports of a significant proportion of HCC cases in settings of NAFLD. Despite the high prevalence of NAFLD and its serious complications the underling molecular events that implicate lipotoxicity remain poorly understood and need further investigation.
Our research interest focuses on normal and diseased liver pathology. The research specifically focuses on metabolic and lipotoxic changes in the pathogenesis of NAFLD, the mechanism of action of various treatment options and response of In vivo model of disease to the treatment.

The Specific areas of our interest are:

In the area of Skin Biology:

  1. To study the cellular and biochemical basis of UVB induced photodamage.

  2. To understand the mechanistic basis for the photo protective role of natural products in skin cells.

  3. To elucidate the role of natural products in promoting cell death in UVB –irradiated melanoma cells

  4. To understand the mechanistic basis for the melanogeneis modulatory activity of natural products

  5. To understand the role of ER strees, autophagy, and apoptosis in UVB –irradiated skin cells.

In the area of Liver Biology:

  1. Cellular and molecular events of lipotoxicity in hepatocytes.

  2. Roe of unfolded protein response (UPR) and autophagy in the development of Lipid droplet formation and lipotoxicity.

  3. Development of diet based animal models mimicking human NAFLD.

  4. Targeting autophagy and UPR for the treatment of lipotoxic conditions such as NAFLD.
