Moderate Long-Term Modulation of Neuropeptide Y in Hypothalamic Arcuate Nucleus Induces Energy Balance Alterations in Adult Rats
Neuropeptide Y (NPY) produced by arcuate nucleus (ARC) neurons has a strong orexigenic effect on target neurons. Hypothalamic NPY levels undergo wide-ranging oscillations during the circadian cycle and in response to fasting and peripheral hormones (from 0.25 to 10-fold change). The aim of the present study was to evaluate the impact of a moderate long-term modulation of NPY within the ARC neur...
متن کاملP-5: Effect of Chronic Stress on Kiss-1 mRNA Expression in Male Rat Arcuate Hypothalamic Nucleus
Background Kisspeptin is a potent stimulator of the hypothalamic- pituitary-gonadal axis and may play a critical role in modulating of stress-induced suppression of reproduction. The aim of the present study was to investigate the effect of glucocorticoid receptor antagonist (RU486) and stress on expression of Kiss-1 mRNA in arcuate nucleus (ARC) of rat hypothalamus.

متن کاملThe hypothalamic arcuate nucleus and the control of peripheral substrates.
The arcuate nucleus (ARC) of the hypothalamus is particularly regarded as a critical platform that integrates circulating signals of hunger and satiety reflecting energy stores and nutrient availability. Among ARC neurons, pro-opiomelanocortin (POMC) and agouti-related protein and neuropeptide Y (NPY/AgRP neurons) are considered as two opposing branches of the melanocortin signaling pathway. In...
متن کاملInsulin Within the Arcuate Nucleus Has Paradoxical Effects on Nociception in Healthy and Diabetic Rats
Broad nervous circuits originate from the hypothalamic arcuate nucleus project to many parts of the brain which are related to pain perception. Insulin receptors have been found in the arcuate nucleus. Since nociception may be affected in type 1 diabetes, the present study aimed to investigate the intra-arcuate nucleus insulin role in pain perception in STZ-induced diabetic and healthy rats. Fo...
