Description of Research Expertise

Research Interests
Signaling mechanisms of insulin secretion. Cytokines and diabetes.

Key words: Insulin secretion, diabetes, cytokine, signal transduction.

Description of Research
My research lab is focused on the signal transduction mechanisms of insulin secretion from the islets of Langerhans within the context of understanding diabetes. Recently, we have identified a novel cytokine called PANDER (FAM3B) which is one of 4 cytokines of a new gene family FAM3. Veryl little is known about the cell biology of PANDER and the role of PANDER in islet biology. PANDER is expressed in islets of Langerhans and is present in secretory granules. PANDER causes apoptosis of beta-cells. PANDER mRNA is upregulated by interferon-gamma treatment in beta-cells. We have 2 working hypotheses that we are testing: is PANDER involved in cytokine-induced destruction of islets and the pathogenesis of type 1 diabetes, does PANDER have any role in beta-cell differentiation? The lab is using a combination of cell biological, biochemical and molecular biology approaches to understand the physiological role of PANDER and its role in diabetes.

Rotation Projects for 2006-2007
- Analysis of PANDER transgenic mouse
- Site-directed mutagenesis of PANDER
- siRNA approaches to downregulate PANDER
- Regulation of PANDER mRNA in beta-cells
- Secretory mechanisms of PANDER in beta-cells
