1. The role of cytoskeletal proteins in signal transduction, hypertonic and oxidative stress. Molecular biology of cell motility. Structure function analysis of gelsolin and CapG, Ca2+ and phosphoinositide regulated actin modulating proteins. Role of these proteins in coordinating signal transduction and the effect of changing phosphoinositide levels on cell proliferation and cytoskeletal remodeling.
2. Isoform specific functions and regulations of phosphoinositide kinases that synthesize PIP2 and PI4P, with particular emphasis on their roles in membrane trafficking (from the plasma membrane and the trans Golgi networkand), cytoskeletal regulation and signaling.
3. Effects of thermal burn injury and oxidative stress on the endothelial cell actin cytoskeleton and phosphoinositide homeostasis.
