Summary
The most promising new osteoporosis therapy is antibody-based inhibition of the sclerostin protein. We discovered that sclerostin is inhibited by oncostatin M (OSM) only when it binds to a receptor called LIFR, which then activates proteins STAT3 and SOCS3. If OSM binds a different receptor (OSMR) it increases STAT1 activity and destroys bone. This project will determine how to manipulate STAT3, SOCS3, and STAT1 to increase bone formation and provide new treatments for osteoporosis.
Novel Anti-Infective Agents That Act By Enhancing The Host Innate Response

Summary
Antibiotic resistance is one of our major challenges, with fears expressed that we may soon run out of effective antibiotics for the treatment of infections. The goal of this project is to develop a novel class of antibiotics that acts by enhancing our immune response to infection rather than attacking the bacteria themselves, and therefore will not be susceptible to the development of bacterial resistance. These agents inhibit the degradation of a key enzyme involved in combating infections.
Understanding SOCS3 Inhibition Of JAK Activity In Myeloproliferative Disorders

Summary
The myeloproliferative disorders are diseases in which abnormal blood cell development leads to a risk of stroke, thrombosis, hemorrhage and leukemia. Remarkably, three of these disorders are caused by an error in a single enzyme that makes it over active. The enzyme, JAK2, controls how cells respond to hormone-like messengers called cytokines. We are investigating a cellular pathway that inhibits this enzyme in order to understand the progression and potential treatment of the disorders.
