Thrombosis and hemostasis
Return to top
My research activities center around two separate, but interrelated, areas: (1) The role of high molecular weight kininogen thrombosis, monocyte secretion, neutrophil stimulation, inflammation and angiogenesis, both in purified systems and in human disease states such as inflammatory bowel disease and arthritis and (2) Stimulus-response coupling in platelets as mediated by cAMP phosphodiesterase type 3A [PDE3A].
Monoclonal peptides, antibodies, molecular biological techniques and molecular modeling are also being used to probe structure-function relationships in kininogen. The peptide sequences responsible for the ability of cleaved kininigen and domain 5 to inhibit angiogenesis and stimulate monocytes to secrete cytokines and chemokines is currently being investigated both in vitro and in vivo using recombinant proteins, site-directed mutagenesis, domain deletion and designed peptides. The structural requirements for kininogen and domain 3 to inhibit thrombosis are being delineated in a model of arterial endothelial injury in an inbred Lewis rat. .The effect of treating angiogenesis with a monoclonal antibody to kininogen in experimental inflammatory bowel disease and arthritis in the same rat is being evaluated.The same antibody is being used to treat tumor angiogenesis in mice.
We have purified platelet cAMP phosphodiesterase type 3A and can be labeled in the active site with a cAMP affinity reagent. We are now investigating the amino acids which are covalently labeled. To place these modified amino acids in the primary structure, we have proteolyzed and sequenced the covalently modified the enzyme and performed site-directed mutagenesis to further define its active site. A new cGMP affinity reagent will be used to probe the active and regulatory sites. We have shown that Akt [PKB] phosphorylated and activated PDE3A.Since Akt is activated by thrombin, we will further investigate thrombin-induced platelet aggregation in PDE3A and Akt gene knockouts.
