Gene References into Functions
  1. High NPY expression is associated with chronic social defeat stress. PMID: 30201296
  2. nalysis of hypothalamic and neuroendocrine responses to HFS throughout the light-dark cycle suggests uncoupling of hypothalamic responses involving appetite-stimulating fasting-responsive hypothalamic neurons expressing agouti-related peptide (AgRP) and neuropeptide Y (Npy). PMID: 28294152
  3. In this study we demonstrate dynamic changes in the number of calretinin- (CR) and neuropeptide Y-expressing (NPY) interneurons in the motor cortex of the familial hSOD1(G93A) ALS mouse model, suggesting their potential involvement in motor neuron circuitry defects. PMID: 28294153
  4. Study demonstrated that Skn-1a is only expressed when neuropeptide Y (NPY) is activated in microvillar cells (MVCs). Therefore the expression of NPY is necessary for the transcription factor-mediated differentiation of olfactory MVCs. PMID: 29530408

Although acute loss of hypothalamic neurons that produce appetite-stimulating neuropeptide Y (Npy) and agouti-related peptide (Agrp) in adult mice or in mice homozygous for the anorexia (anx) mutation causes aphagia, our understanding of the factors that help maintain appetite regulatory circuitry is limited PMID: 28093506

  13. arcuate nucleus NPY neuropathway to the paraventricular nucleus and dorsomedial hypothalamus is pivotal in obesity-induced elevations in sympathetic nerve activity. PMID: 28628036
  14. NPY promotes airway hyperresponsiveness through the induction of Rho kinase activity and phosphorylation of myosin light chain, which induces airway smooth muscle contraction. PMID: 27088802

  16. Npy expression is decreased in the cingulate cortex following chronic unpredictable stress. PMID: 27737789
  17. The results showed that NPY system activity is increased in a time- and space-dependent manner during bone repair. PMID: 27802308
  18. Decreased neuropeptide Y (NPY) expression in the extended amygdala might be causally linked with the depression induced following type 2 diabetes and that the antidepressant action of imipramine in diabetic mice might be mediated by NPY-NPY Y1 receptor system. PMID: 27208493
  19. lipolytic/thermogenic signaling, beta3-adrenergic receptor/hormone sensitive lipase, was markedly activated in white adipose tissue of NPY(-/-) mice compared with that of NPY(+/+) mice. PMID: 28101970
  20. These data establish the existence of a microRNA-mediated cross talk between enteric neurons producing NPY and intestinal epithelial cells, and the potential of neuropeptide-regulated miRNAs as potential therapeutic molecules for the management of inflammation-associated tumors in the gut. PMID: 27856419
  21. Stress may be associated with elevated peripheral neuropeptide Y level, which was observed to be associated with exacerbated airway inflammation in asthmatic mice. PMID: 26673939
