Summary
The aim of this study is to investigate the cause of reduced glucose induced insulin secretion in type 2 diabetes. In pancreatic beta-cells, insulin is packaged and stored in secretory granules (SGs). Upon stimulation, these SGs deliver insulin to the bloodstream. It is known that insulin SGs exist in two functionally distinct pools; and one pool is preferentially secreted upon stimulation. How a cell can differentiate the two SG pools is unclear, and we will address this issue in this project.

Summary
Colorectal cancer (CRC) causes over 4000 deaths/year, typically from developing drug resistance and spreading to other organs (metastasis). These processes involve tumour cells called cancer stem cells (CSCs), which rely on specific cell surface proteins for survival and function. We are developing antibodies against one of these type of proteins, to test in mouse models of CRC. These already show promise in targeting CSCs and inhibiting drug-resistance and metastasis in mice.
Defining The Molecular Effectors Of Gene/environment Interaction On Mouse Heart Development

Summary
One third of all birth defects involve the heart, and are the most common cause of infant death. Some defects are due to genetic factors, but others arise when the pregnant mother is exposed to environmental stress. We will examine how one stress (low oxygen levels) causes abnormal heart formation in the embryo, look at what causes this at a molecular level, and explore if such stress increases the risk of heart defects in families with a history of such abnormalities
