Life is a cyclical chemical process from birth to death, which consists of developmental changes from single cell to adult and aging changes from adult to death. There are internal circannual cycles, circadian rhythms with in this birth to death cycle. Disruption of circadian rhythms might increase the risk of cancer, obesity. Mechanisms based on transcriptional and translational feedback loop (TTFL) is a current model for molecular circadian clocks in eukaryotic cells. Recent discovery of Red-Ox cycles of peroxiredoxin proteins in cells has prompted a reappraisal of TTFL model.
Our research work is focused on the temporal compartmentalization of metabolism that takes place during such circadian cycles. Studying cyclic changes in cellís metabolic state, which may be a fundamental driving force for such biological oscillations. By using un-targeted & targeted metabolomics, we are trying to understand metabolic state of cells and different model organisms.
