Preprotachykinin gene expression in goldfish brain: sexual, seasonal, and postprandial variations.

P Peyon1, H Saied, X Lin, R E Peter.   

Abstract

Recently, we described the complete nucleotide sequence of gamma-preprotachykinin (gamma-PPT) mRNA and the deduced amino acid sequence of the precursor on the basis of molecular cloning and sequence analysis of cDNA from goldfish brain. In the present study, gamma-PPT gene expression in the brain of goldfish was examined using quantitative Northern blot analysis. The results showed that the gamma-PPT gene is highly but differentially expressed in the olfactory bulbs, hypothalamus, and posterior brain regions. There are sexual dimorphism and seasonal variations in gamma-PPT gene expression. In addition, the postprandial changes in gamma-PPT gene expression in the olfactory bulbs and hypothalamus suggest that tachykinin peptides are involved in regulation of feeding behavior in goldfish.
