Molecular targets of ethanol in the brain: We are studying the actions of alcohol on the proteins involved in the presynaptic SNARE complex that regulates synaptic vesicle fusion and neurotransmitter release. Munc13-1 is one of such presynaptic active zone-protein implicated in modulating short-term presynaptic plasticity. We are looking at the effects of ethanol on the expression of this protein in in vitro cell culture and in vivo rodent models and how drinking can affect neurotransmitter release in different brain regions. The long-term goal of this project is to identify molecular targets of ethanol and design drug based on these targets. Development of subtype specific PKC activators/inhibitors: Protein Kinase C (PKC) is a serine threonine kinase that plays a central role in signal transduction, regulating divergent cellular functions. Aberrations in PKC signaling have been implicated in the development of multiple human diseases including several types of cancer, metabolic and cardiovascular complications of diabetes, central nervous system dysfunctions, neuronal degeneration and cardiovascular disorders and alcoholism. Our ongoing research aims at developing subtype specific activators/inhibitors leading to therapeutics. We are developing molecules based on simple chemical scaffold and testing their effects on subtype-specific PKC activities. To accomplish our goals, we use cell and molecular biology, protein biochemistry, histology, confocal microscopy, rodent brain micro-dissection, primary neuronal culture, X-ray crystallography, organic synthesis and molecular docking techniques.
