Example sentences for: melanocortin
How can you use “melanocortin” in a sentence? Here are some example sentences to help you improve your vocabulary:
We had previously shown that fasting could regulate hypothalamic gene expression in insulin-deficient mice even though in these mice fasting did not influence plasma leptin or insulin [ 5 ] . Since adrenalectomy blocked the fasting-induced reduction in melanocortin tone in diabetic mice (as it had in euglycemic mice in the first study), these results suggest that effects of fasting on melanocortin tone in diabetic mice may be mediated at least in part by a rise in plasma corticosterone (itself possibly secondary to the reduction in plasma leptin).
POMC is cleaved post-translationally producing bioactive peptides (adrenocorticotrophin, β-endorphin and α-, β- and γ-melanocyte stimulating hormones) that interact with neurons expressing melanocortin receptors, leading to appetite suppression [ 91 ] . Feeding high fat diets is known to increase Pomc expression [ 92 ] . Herein, FUNG feeding resulted in a 6.0* fold increase in hippocampal Pomc, whereas FISH and the combination diet had smaller, non-statistically significant effects (6.
Therefore in the present study we assessed if an elevation of plasma corticosterone is necessary and sufficient to mediate effects of fasting and insulin deficiency on hypothalamic melanocortin tone, as indicated by expression of hypothalamic AGRP and POMC mRNA.
3A), and serum insulin, leptin and melanocortin tone were also reduced in this condition (Fig.
Since both fasting and insulin deficiency are associated with reduced plasma leptin [ 5 ] , and leptin replacement reverses effects of fasting [ 6 ] and also effects of insulin deficiency on food intake and body weight [ 7 ] , it has been suggested that the reduction in leptin accounts for the reduced hypothalamic melanocortin tone in these conditions.
