“…A particularly prominent example is neuropeptide Y (NPY; NPF in insects), which alters feeding behavior in worms (De Bono and Bargmann, 1998), insects (Wu et al, 2003) and all major vertebrate lineages (fish: Lopez-Patino et al, 1999;frogs: Crespi et al, 2004;reptiles: Morris and Crews, 1990;birds: Strader and Buntin, 2001;and mammals: Stanley and Leibowitz, 1984), suggesting an evolutionarily ancient role for this peptide in foraging behavior. Although this remarkable evolutionary conservation of feeding-related molecules is quite well documented, the involvement of these molecules in the evolution of social behavior is just beginning to be appreciated (Ament et al, 2010;O'Rourke and Renn, 2015;Schneider et al, 2013).…”

Adaptive trade-offs between foraging and social behavior intuitively explain many aspects of individual decision-making. Given the intimate connection between social behavior and feeding/foraging at the behavioral level, we propose that social behaviors are linked to foraging on a mechanistic level, and that modifications of feeding circuits are crucial in the evolution of complex social behaviors. In this Review, we first highlight the overlap between mechanisms underlying foraging and parental care and then expand this argument to consider the manipulation of feeding-related pathways in the evolution of other complex social behaviors. We include examples from diverse taxa to highlight that the independent evolution of complex social behaviors is a variation on the theme of feeding circuit modification.

“…F was previously calculated in the absence of fish to determine the effect of water dissolution on food pellets during the feeding time, and represents the reduction in food weight after food remains 5 h into the aquaria (F = 0.856 -0.0054) following previous studies. 9,39 At the end of the FI experiment (ZT 9), zebrafish were anesthetized (0.1 mg/L MS222; Sigma) and livers, muscles, and intestines were dissected and stored at -80°C until analysis. Considering RNA sensitivity, the sampling of liver, intestine, and muscle from each fish was performed as fast as possible 276 PICCINETTI ET AL.…”

Melatonin and Peripheral Circuitries: Insights on Appetite and Metabolism in Danio Rerio

et al. 2013

Melatonin is a neuroendocrine transducer of circadian/circannual rhythms able to synchronize organism's physiological activity. On the basis of our recent findings on appetite regulation by melatonin in the zebrafish brain, the aim of this study was to evaluate melatonin's role in peripheral circuitries regulating food intake, growth, and lipid metabolism. For this purpose, the effect of two melatonin doses (100 nM and 1 lM) administered for 10 days, via water, to adult zebrafish was evaluated at both physiological and molecular levels. The major signals controlling energy homeostasis were analyzed together. Additionally, the effect of melatonin doses on muscle metabolic resources was evaluated. The results obtained indicate that melatonin reduces food intake by stimulating molecules involved in appetite inhibition, such as leptin (LPT), in the liver and intestine and MC4R, a melanocortin system receptor, in the liver. Moreover, melatonin decreases hepatic insulin-like growth factor-I (IGF-I) gene expression, involved in growth process and other signals involved in lipid metabolism such as proliferator-activated receptors (PPARa, b, and c) and sterol regulatory element-binding protein (SREBP). These results were correlated with lower levels of lipids in the muscles as evidenced by the macromolecular pools analyses. The findings obtained in this study could be of great interest for a better understanding of the molecular mechanisms as the basis of food intake control and, in turn, can be a useful tool for medical and aquaculture applications.

“…A large number of neuropeptides regulate food intake and energy homeostasis, including orexigenic factors, such as neuropeptide Y (NPY), Agouti-related protein (AgRP) and orexins; and anorexigenic factors, such as pro-opiomelanocortin (POMC) and cocaine-and amphetamine-regulated transcript (CART) (Volkoff et al, 2009). In goldfish (Carassius auratus) and catfish (Ictalurus punctatus), intracerebroventricular (ICV) injections of NPY stimulated food intake (Lopez-Patino et al, 1999;Silverstein and Plisetskaya, 2000). Furthermore, the hypothalamic expression of NPY mRNA increased in response to fasting in goldfish and salmon (Narnaware and Peter, 2001;Silverstein et al, 1998).…”
