Abstract

Pancreatic beta cell disease in dogs can manifest as diabetes mellitus, where beta cells are destroyed, or insulinoma, where these cells undergo malignant transformation. Samoyed dogs are highly susceptible to the former, suggesting that they have ‘fragile’ beta cells. In contrast, Boxer dogs rarely develop diabetes, but are prone to developing insulinomas. The aim of this project is to identify novel genes involved in pancreatic beta cell function, apoptosis and regeneration, by whole genome sequencing analysis in Boxers and Samoyeds. It is anticipated that this will provide insight into pathways and molecular targets that might be suitable for therapeutic intervention.
