Summary
Obesity is a significant public health issue due to its increasing prevalence and association with other diseases including cardiovascular disease. Efforts to pharmacologically prevent and treat obesity are impaired by an incomplete understanding of the genes and metabolic processes involved. This project will use cell and animal models to examine the processes that occur during the expansion of fat tissue which will broaden our understanding of obesity and assist in identifying new therapies.

Summary
Our previous studies implicated the enzyme protein kinase C epsilon (PKCe) in the development of fat-induced insulin resistance, a key aspect of Type 2 Diabetes. Contrary to expectations we have now shown that animals lacking PKCe only in fat are protected from whole body insulin resistance when fed a high-fat diet. This project will investigate the mechanisms through which PKCe in fat affects insulin action at other tissues, especially liver, to disrupt normal control of blood sugar levels.

Summary
Prof Harvey’s work explores the molecular and cellular networks that underpin heart development in the embryo and heart regeneration in the adult, and how these networks unravel in heart disease. Based on this knowledge, his work seeks to develop novel approaches for alleviating suffering in babies with congenital heart defects and adults enduring the devastating consequences of heart attack or heart failure.
Identifying A Novel Role For Pigment Epithelium-derived Factor In Obesity-related Metabolic Dysfunction

Summary
Obesity is an important factor contributing to insulin resistance and type 2 diabetes; however, the factors linking these disorders are not well defined. A protein called PEDF is elevated in obesity and type 2 diabetes. This project will examine how PEDF causes insulin resistance and whether blocking PEDF's actions prevents insulin resistance. Successful completion of this project may lead to therapeutics that reduce the risk of developing type 2 diabetes.
Metabolic control of organ growth and regeneration. One of the fundamental questions in biology is to understand how organ size is regulated at the cellular and organismal level. The Hippo/Yap pathway plays a central role in the regulation of organ size and it is impacted by environmental cues including nutrient status. This research proposal aims to use zebrafish to elucidate the role that the Hippo/Yap pathway plays in reprogramming lipid metabolism to fuel tissue growth in development and reg ....Metabolic control of organ growth and regeneration. One of the fundamental questions in biology is to understand how organ size is regulated at the cellular and organismal level.

This research proposal aims to use zebrafish to elucidate the role that the Hippo/Yap pathway plays in reprogramming lipid metabolism to fuel tissue growth in development and regeneration. Ultimately, this work aims to identify metabolic dependencies required for organ growth and regeneration. Expected outcomes include scholarly publications revealing fundamental principles underlying tissue growth, new resources for the research community and training for research students.Read moreRead less
Adaptive reprogramming of metabolism in regeneration. . Biologists have long been intrigued at the phenomenon of organ regeneration. Unlike most human organs, the liver exhibits the remarkable capacity to regenerate. Despite decades of research, the molecular underpinnings of liver regeneration are poorly understood. This research proposal aims to use zebrafish to elucidate the pathways involved in sensing injury and activating an adaptive transcriptional and metabolic response to orchestrate re ....Adaptive reprogramming of metabolism in regeneration. .
