Adenosine monophosphate-activated protein kinase AMPK acts as a sensor of cellular energy changes and is involved in the control of food intake. A total of 1-d-old broilers were randomly allotted into 3 treatments with 6 replicates per treatment and 12 broilers in each cage. The present study was conducted to investigate the effects of dietary energy level on appetite and the central AMPK signal pathway. Overall, the central AMPK signal pathway and appetite were modulated in accordance with the energy level in the diet to regulate nutritional status and maintain energy homeostasis in birds. The regulation of voluntary food intake in animals and humans is complex and involves central and peripheral regulatory mechanisms Lenard and Berthoud, In the central nervous system CNS, the hypothalamus is the brain region that regulates food intake and energy homeostasis Gustavo et al. Peripheral metabolic hormones released by the gastrointestinal tract during digestion act as episodic satiety signals and regulate appetite and energy metabolism by targeting hypothalamic nuclei Joanne et al. Increasing evidence has shown that AMPK has a central role in mediating the appetite-modulating and metabolic effects of several hormones and substances Kola et al. Studies have found that AMPK activation or deactivation in the hypothalamus increases or decreases food intake Andersson et al. High-fat diet-induced obesity can alter AMPK activity in the hypothalamus and skeletal muscle Martin et al.
Recent evidence has demonstrated that AMPK has wider functions with respect to regulating immune cell metabolism and function. This in turn can result in subsequent negative downstream effects on glucose, lipid and insulin metabolism. Nutrient stress in the form of obesity can impact AMPK and whole-body metabolism, leading to complications such as type 2 diabetes and cancer risk. There is a lack of data regarding the nature and extent that nutrient status has on AMPK and metabolic-inflammation. However, emerging work elucidates to a direct role of individual nutrients on AMPK and metabolic-inflammation, as a possible means of modulating AMPK activity. The posit being to use such nutritional agents to re-configure metabolic-inflammation towards more oxidative phosphorylation and promote the resolution of inflammation. It is responsible for adapting cellular metabolism in response to nutritional and environmental variations. This involves activating pathways to produce energy whilst also inhibiting energy-consuming pathways. AMPK can be activated through both allosteric and phosphorylation p means. AMPK activation, in response to low energy status, re-configures glucose, lipid and mitochondrial metabolism towards adenosine triphosphate ATP production and decreases anabolic pathways that would otherwise further deplete ATP levels Figure 1. One of the main mechanisms of AMPK activation is the prevention of its dephosphorylation by AMP, especially within the context of metabolic disease [ 6 ].
