title: The molecular biology of preprotachykinin-A gene expression.
abstract: The expression of neuropeptides is largely tissue-specific and under strictly regulated and complex control. In view of the diversity of neuronal phenotypes, with concomitant plasticity of gene expression within any phenotype, it is obvious that there is coordinated activation and repression of genes. One of the central observations from these studies is that neuropeptide gene expression is dependent upon the combinatorial interaction of multiple transcription factors with the regulatory elements which determine mRNA synthesis. These factors mediate both tissue specific and stimulus inducible gene expression. We will illustrate some of the mechanisms that regulate neuropeptide gene expression utilizing our own studies on the rat preprotachykinin-A gene (rPPT) and, where appropriate, expand on the generality of these findings to other neuropeptide genes.
