Full textDisruption of stress response mechanisms in organisms can lead to cellular dysfunction and diseases like metabolic syndrome. Energy balance is mainly regulated by the central nervous system (CNS), which integrates hormonal, neuronal, and dietary signals from various tissues. Dysfunction in this system is linked to obesity and metabolic syndrome, both precursors to type 2 diabetes (T2D). Our laboratory discovered that calcium/calmodulin-dependent protein kinase ID (CaMK1D), a gene associated with T2D, promotes ghrelin-mediated food intake in mice. However, CaMK1D signaling in NPY/AgRP neurons still remains questions. In this work, we proformed RNA sequencing using the GT1-7 hypothalamic cell line. To this end, we found that CalHM6 is a downstream target of CaMK1D signaling. CalHM6 mRNA levels were significantly upregulated in CaMK1D-/- cells and downregulated when CaMK1D was re-expressed. This was confirmed in vivo in the hypothalamus of CaMK1D-/- mice. CalHM6, likely a voltage-gated calcium channel, showed increased intracellular Ca2+ levels in response to ghrelin in CaMK1D-/- cells compared to CaMK1D+/+ cells using jGCamps method. Altogether, our work showed CalHM6 is a novel target of CaMK1D. High CaMK1D, leading to low CalHM6 expression, may enhance food intake and obesity by modulating calcium-dependent signaling in NPY/AgRP neuron

Full textSeveral neuronal populations are involved in the regulation of energy balance. Among these, the hypothalamic agouti-related protein neurons (AgRP-neurons) are well characterized for their ability to promote food intake. Using cell-specific ablation we investigated a possible role of AgRP neurons in nutrient partitioning independent from food intake. We show that mice lacking AgRP neuron developed a non-hyperphagic obesity due to increased feed efficiency (weight gain/kcal consumed) on regular chow. At a time that preceded obesity catecholamine turnover rate was selectively decreased in the pancreas, liver, and glycolytic muscle, while it was increased in oxidative muscle. Respiratory quotient measurements revealed a change in substrate utilization towards lipid oxidation enhanced by synergistic increase in liver triglyceride synthesis and lipid substrate preference in oxidative muscle mitochondria. On high fat diet, mice lacking AgRP neurons displayed reduced body weight gain and paradoxical improvement in glucose tolerance. Finally we evidenced that Gamma Aminobutyric Acid (GABA) made by AgRP neurons is important in the central control of peripheral substrate utilization. This study reveals a new function for AgRP neurons in the coordination, via the sympathetic nervous System, of inter-organs communication and nutrient partitioning. These results offer a new conceptual framework for the understanding of obesity-related disorders
