title: The C/EBP-binding region and adjacent sites regulate expression of the adipose P2 gene in human preadipocytes.
abstract: Human preadipocytes contain nuclear factors that specifically bind to the AE-1 sequence, previously demonstrated as an enhancer element in the regulation of adipose P2 gene expression during 3T3 adipose differentiation. By transient transfection and in vivo competition experiments, the trans-acting factors were found to bind either to the C/EBP recognition site in the AE-1 sequence and act as a negative regulator or to the adjacent site (termed 3' AE-1) and act as a positive regulator of adipose P2 gene activity in human preadipocytes.
