14	8284270	Insulin-deficient diabetes and food deprivation markedly increase hypothalamic NPY and NPY mRNA levels, suggesting increased activity of NPYergic pathways in the hypothalamus, which could account for hyperphagia and neuroendocrine changes in these conditions.
15	8194661	NPY administration also resulted in a pronounced increase in the in vivo insulin-stimulated glucose uptake by adipose tissue but in a marked decrease in uptake by eight different muscle types.

24	16177033	Experiments in vivo also demonstrated that increases in GAD65 mRNA expression in the arcuate nucleus preceded decreases in the NPY mRNA expression in a fasting-refeeding paradigm and that intracerebroventricular injection of insulin increased GAD65 mRNA expression in the arcuate nucleus in fasted rats.
