Molecular regulation of adipocyte differentiation.
Significant advances have been made recently toward understanding the molecular events that regulate adipocyte differentiation. In vitro models of adipogenesis, such as the 3T3-L1 and F-442A preadipocyte cell lines have proven to be an invaluable resource in elucidating mechanisms of adipocyte differentiation. Subject to modulation by hormonal, dietary, and genetic influences, the differentiation program now appears to be distinctly controlled through the coordinate regulation of transcription factors that predominantly include members of the C/EBP and PPAR families. Increased understanding of these critical factors and how they are regulated will provide insights into adipose tissue development as well as treatment of obesity.DOI: 10.1006/scdb.1998.0276
