Thiols: Biology and implications for human disease

Shantanu Sengupta’s primary focus is on the role of homocysteine and other thiol amino acids at the cellular level. He has adopted a combination of genetic, biochemical and proteomics approaches to study the consequences of abberant levels of this metabolite, implicated in cardiovascular disease and neurological diseases.

His research interests include:
Genetic basis of Cardiovascular Disease
Toxic effects of Thiol compounds like Homocysteine
Role of homocysteine in epigenetic modifications

He uses the power of yeast molecular genetics to understand the effects of metabolites in the thiol biosynthesis pathway.
