..., we assessed the effects on food intake of intracerebroventricular treatment with agonists of these receptors. In the second experiment, we assessed the impact of the same treatments on mRNA abundance in the hypothalamus and hindbrain of neuropeptides involved in the metabolic control of food intake...

...Ayelén M. Blanco; Juan I. Bertucci; José L. Soengas; Suraj Unniappan ABSTRACT This research assessed the direct effects of insulin on nutrient-sensing mechanisms in the brain of rainbow trout ( Oncorhynchus mykiss ) using an in vitro approach. Cultured hypothalamus and hindbrain were exposed to 1...

... injected ICV GHRL and ceramide alone or in combination to evaluate in hypothalamus and hindbrain changes in parameters related to the metabolic control of food intake. The presence of ceramide generally counteracted the effects elicited by GHRL on fatty acid-sensing systems, the capacity of integrative...

...) in hindbrain. However, these effects of glucose might be indirect. Therefore, we evaluated the response of parameters related to these glucosensing mechanisms in a first experiment using pooled sections of hypothalamus and hindbrain incubated for 6 h at 15°C in modified Hanks' medium containing 2, 4 or 8 mmol...
