In summary, these results indicated that npy has an orexigenic role in gibel carp.
Kisspeptin directly excites anorexigenic proopiomelanocortin neurons but inhibits orexigenic neuropeptide Y cells by an indirect synaptic mechanism.
Ghrelin, the orexigenic peptide hormone also affects glucose metabolism.
A lack of adaptation in the secretion of neuroendocrine orexigenic signals to calorie-dense diets could explain these phenomena.
Acute suppression of appetite from exercise may be due to changes in appetite-regulating hormones, by simultaneously suppressing acylated ghrelin (orexigenic hormone) and increasing peptide YY (anorexigenic hormone) up to 9 hours after exercise [34].
However, the activity of hypothalamic proteins involved in the regulation of the satiety centre was unusual, because in 3-week-old cockerels, increase in transcript abundance of genes encoding proteins involved in both anorexigenic and orexigenic pathways was observed.
Leptin signaling is primarily mediated through orexigenic peptides, such as neuropeptide Y (NPY) and agouti-related peptide (AgRP), and anorexigenic peptides, such as proopiomelanocortin (POMC) and cocaine- and amphetamine-regulated transcript (CART), in the arcuate nucleus of the hypothalamus [1].
In rats, the injection of visfatin in the arcuate nucleus of the hypothalamus plays an orexigenic role via the modulation of dopamine, CART, and CRH peptide activity [177].
It is also an orexigenic hormone that activates AgRP neurons to increase food consumption and body weight [9].
Acting on hypothalamic nuclei, leptin decreases food intake and increases energy consumption, via induction of anorexigenic factors and suppression of orexigenic neuropeptides [28].
Hypothalamic mTOR signaling mediates the orexigenic action of ghrelin.
