Research Description:

My research is on the mechanism of action of mood stabilizing drugs at molecular and cellular levels, with focus on the neuroprotective effects of these drugs against oxidative stress. Previously,we found that mood stabilizing drugs prevented oxidative damage and upregulated glutathione (GSH)/glutathione S-transferase (GST) detoxification pathway. My research objective is to understand the role of GSH/GST pathway in the pharmacological treatment of mood stabilizing drugs. Research aims are: 1) to examine if GSH and GST mediate the neuroprotective effects of mood stabilizing drugs against oxidative damage; 2) to determine the role of Nrf2 transcription factor in GSH/GST pathway regulated by mood stabilizing drugs; 3) to identify oxidative modifications of synaptic proteins and 4) to determine role of GSH/GST pathway in mood stabilizing treatment using animal models for depression and mania. This study will lead to identifying new therapeutic targets in the GSH/GST pathway for investigation in clinical trials in the near future, contributing to new and more effective therapies for bipolar disorder with fewer side effects.

Research techniques employed in my work include cell culturing, measurement of lipid peroxidation and protein oxidation, TUNEL staining, real time-PCR,DNA cloning, in vitro transcription and translation, cell transfection,immunoblotting analysis, co-immunoprecipitation, immunohistochemistry, electrophoretic mobility shift assay, locomotor activity analysis and forced swim test among others.
