New publication on Protein-tyrosine phosphatase 1B (ptp1b) from Peti and Page labs in Nature Chemistry Biology

Protein-tyrosine phosphatase 1B (ptp1b) is a signaling protein that plays a role in a variety of pathways associated with diseases including cancer, diabetes, and obesity. As a result there has been a great deal of interest in developing inhibitors of this enzyme. However, the nature of the chemistry it performs has proven a significant barrier to creating effective drugs. Brown University students Dorothy Koveal and Dan Miller, with Professors Wolfgang Peti and Rebecca Page, collaborated with research teams at the University of Toronto and Institut de Biologie Structurale in Grenoble to characterize an inhibitor, MSI-1436, that interferes with ptp1b function without binding to the active site.

Investigating the Function of a Novel Ultraviolet-Activated Pathway in Mice with Humanized Skin
Human skin is constantly exposed to solar ultraviolet radiation (UVR), a powerful environmental risk factor for skin cancer, which accounts for more than half of all human malignancies. Exposure to low doses of ultraviolet radiation results in increased skin pigmentation, while exposure to high doses correlates with skin cancer. The larger goal of Oancea's research is to understand the molecular processes that control the human skin's ability to detect and respond to UVR. Read More.

Phosphatase Inhibitor Design – A Unique Possibility for Brown University

The specific and reciprocal relationship between kinases and phosphatases controls most biological processes. Thus, when the balance is disrupted, the result is often disease. To date, efforts to modulate phosphate signaling to treat these diseases have focused on inhibiting kinases. However, it has recently become evident that the exquisite regulation of phosphorylation signaling is driven by tyrosine and serine/threonine phosphatases, rather than by kinases. Thus, one of the fastest growing areas of research is to identify potent, specific inhibitors of phosphatases. The Seed team, including Dr. Christopher Seto and Dr. Paul Williard, will combine expertise in biochemistry, structural biology, biophysics and synthetic organic chemistry in order to develop novel, potent inhibitors of phosphatases.
