| abstractText | Neuropeptide Y (NPY) plays an important role in the central regulation of neuronal activity, endocrine and sexual behavior, and food intake. Although transcription activity of the NPY gene in PC12 cells is regulated by a number of agents such as nerve growth factor (NGF), the mechanism responsible for the NGF-elicited increase in the transcription of the NPY gene remains to be explored. In this study, we isolated and characterized a nuclear protein that is bound to NGF-response elements (NGFRE) that lie between nucleotide -87 and -33 of the rat NPY promoter gene. This nuclear protein is identical to the rat homolog of human transcription factor AP-2alpha. We further demonstrated that rat AP-2a promotes efficient NPY transcription activity in response to NGF. Finally, we provide direct evidence that the mice lacking transcription factor AP-2alpha exhibit reduced expression of NPY mRNA compared with wild-type mice, further supporting the hypothesis that AP-2alpha is an important transcription factor in regulating NPY transcription activity. |
