Techniques evolved in the post -omics era have given us opportunity to accelerate discovery process by looking at many cellular processes simultaneously. Advances in computational power, algorithms, and modern database mining techniques are accelerating the discovery science even more. New powerful techniques to study large number of genes and proteins at a time are getting more and more sophisticated. New strategies are emerging to identify the role of specific genes in causing and counteracting diseases.

We have successfully established a laboratory where we can integrate molecular biology, genomics, proteomics, QSAR and protein modelling to identify pathways, regulatory proteins, putative drug targets and small molecule agonist/antagonist using modern techniques. Presently we are engaged in the following work.

Chemical genetics approach is used to understand the biological functions of a protein without mutating the protein. This approach can identify small molecules that would be valuable in deciphering function of homologous proteins in a wide variety of organisms. We are using in-silico techniques for searching novel inhibitors of yeast, leishmania and mycobacterium sirtuins.

In last century achievements of recombinant DNA technology has revolutionised modern biology and accomplish significant dynamic growth of biotech industries. The basis of this new technology is the ability to introduce genetic material from virtually any source in to cells to alter the genetic makeup of the cell and produce desired products. We are currently engaged in cloning of a two commercially important gene phytase from A. niger and oxido-reductase from G. candidum .

Calorie restriction (CR) alters normal physiology in mammals and imparts many other health benefits. However, therapeutic application of CR in humans lacks feasibility. We are exploiting the usefulness of S. cerevisise and effectiveness of microarray to identify promising CR mimetic candidates, thus saving time, cost and animal life for initial screening.

The phenomenon ‘caloric restriction’ (CR; a diet in which calories are limited by 30-40% compared with animals fed ad libitum ) decreasess oxidative stress in a variety of species and has been the focus of much interest lately. However the mechanisms of CR remain to be clearly elucidated. Using proteomics technoques we are studying oxidative stress regulation in yeast and rat models.
