title: Short-term fasting differentially alters PACAP and VIP levels in the brains of rat and chicken.
abstract: The present article investigated the levels of pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal polypeptide (VIP) in the brains of rats and chickens 12, 36, and 84 h after starvation. PACAP levels increased in both species, 12 h after food deprivation in rats, and with a 24-h delay in chickens. VIP levels showed a more complex pattern: a gradual increase in the hypothalamus and telencephalon, and a significant decrease in the brain stem of rats. In chickens, a decrease was observed in every brain area after 36 h of starvation. These data show that PACAP and VIP are differentially regulated and are involved in the regulatory processes under a food-restricted regimen, and are differentially altered in nocturnal and diurnal species.
