Research Focus

The theme has long been the molecular identification, pathways and structural biology of the molecules constituting the pathogenetic mechanisms of major diseases particularly those that involve vascular biology. Following competitive identification, cloning and establishment of functional pathways of the blood coagulation system we identified various disease associated lipoproteins, then addressed application of these and other molecular pathways and functions to therapeutic design. Major advances are being realized in detailed elucidation the coagulation, aka thrombogenic, molecular cascades and the discovery of precise selective molecular interventions based on the structural biology of the involved precise structural interactions of proteins. Going beyond attenuation of thrombotic disease, the molecular insight has been advanced to therapeutic thrombosis of solid tumors for infarctive eradication. Analysis of in vivo gene display by the vasculature of solid tumors has led to new insight and targets for safe and effective cancer therapy. Lead therapeutic compounds have been designed, patented and advancing to clinical trials. We continue to focus on search and discovery science to advance knowledge and solutions based on the molecular maps of pathogenetic processes.
