ABSTRACT
Neuropeptide Y(NPY) is known to play a pivotal role in various physiological functions including appetite and reproduction. While studies in mammals, fishes and reptiles suggest a temporal and evolutionary conserved role of NPY, the information in amphibian is scanty. We have investigated the reproductive phase related variations of NPY in the brain of Microhyla ornata (M. ornata), using immunohistochemistry and reverse transcription quantitative PCR (RT-qPCR). The highest expression of NPY peptide was observed in the preoptic area (Poa), nucleus infundibularis ventralis (NIV) and nucleus reticularis isthmi (NRIS) of M. ornata in breeding season compared to pre-breeding as well as post-breeding season. In parallel, highest mRNA levels of NPY were also observed in the breeding season in the middle region of brain that includes hypothalamus of M. ornata. Variation in the levels of NPY peptide and mRNA levels in the brain of M. ornata point towards seasonal control of appetite and reproduction.
