Differentiation Determining Fat Cell Fate

Adipose tissue serves as the body's site for energy storage and expenditure. A fair amount is known about the gene functioning in adipocyte differentiation; however, we are lacking knowledge of the players involved in early adipogenesis. Tong et al. used a fruit fly model system to identify two vertebrate GATA factors that, like their homologs in Drosophila, function in adipose tissue. The proteins GATA-2 and GATA-3 hold differentiating cells in the preadipocyte stage and, hence, regulate the preadipocyte to adipocyte transition. Several mouse models of obesity display a reduction in adipose expression of GATA-2 and GATA-3. Because GATA factors function in adipose tissue in both the fly and mouse, these proteins may serve as appropriate targets for obesity studies and therapy.
