2.7.1.105 | malfunction | knockdown of PFKFB3/iPFK2 in N-43/5 neurons causes a decrease in rates of glycolysis, which is accompanied by increased AMPK phosphorylation, increased AgRP mRNA levels and decreased CART mRNA levels. Overexpression of PFKFB3/iPFK2 in N-43/5 neurons causes an increase in glycolysis, which is accompanied by decreased AMPK phosphorylation and decreased AgRP mRNA levels and increased CART mRNA levels | Mus musculus |
2.7.1.105 | metabolism | re-feeding increases plasma levels of glucose and insulin and stimulates PFKFB3 expression. Glucose and insulin stimulate PFKFB3 expression, increase glycolysis, and decrease AMPK phosphorylation in clonal hypothalamic neurons | Mus musculus |
2.7.1.105 | physiological function | role for PFKFB3/iPFK2 in regulating glycolysis in hypothalamic neurons, in the context of neuronal glucose sensing and neuropeptide expression. PFKFB3/iPFK2 responds to re-feeding, which in turn stimulates hypothalamic glycolysis and decreases hypothalamic AMPK phosphorylation and alters neuropeptide expression in a pattern that is associated with suppression of food intake | Mus musculus |
