Funded Activity Summary

Obesity is becoming more common in Australian adults and children, and is a major contributor to a number of diseases including type 2 diabetes, cardiovascular disease and some cancers. Current weight loss strategies using either lifestyle modification (diet and exercise) or drugs are relatively ineffective in the majority of obese individuals. This is partly due to the fact that we have an incomplete knowledge of the factors that regulate weight in humans. In laboratory studies we have shown that human fat cell development can be dramatically accelerated by fibroblast growth factor-1 (FGF-1). This growth factor is produced by human endothelial cells, which are cells that line the blood vessels in fat tissue. When human fat cell precursors (preadipocytes) are cultured in the presence of FGF-1 the preadipocytes divide much more rapidly than normal and, additionally, then develop into mature fat cells much more rapidly than normal. These processes involved in development of new fat cells form the basis of fat tissue expansion in the body. The effect of FGF-1 on human fat cell development is far greater in magnitude than that of other known factors that promote fat cell growth. The aim of this project is to determine the actual biochemical pathways that mediate the effect of FGF-1 in promoting fat cell growth and development. Results obtained will provide insight into the cellular and molecular mechanisms regulating expansion of fat tissue mass in humans. Research aimed at identifying these underlying mechanisms, or at potentially contributing or exacerbating factors, is critically important in development of novel and more effective approaches to prevention and treatment of obesity.
