Recombinant Human Peptide YY protein (PYY), partial

1. the current review aims to compile, evaluate and summarise current knowledge on PYY, with particular emphasis on obesity and diabetes treatment, and the importance of specific Y receptor interactions for this. PMID: 29412828
2. Data show that peptide YY (PYY) mRNA levels were ~ 40,000-fold higher in mouse than human islets, suggesting a more important role of locally secreted Pyy in mouse islets. PMID: 29455414
3. Data suggest that dose/intensity-response relationships exist between exercise intensity and total plasma PYY levels, though the effects on total plasma GLP1 levels and hunger perceptions seem unclear. (PYY = peptide YY ; GLP1 = glucagon-like peptide 1) PMID: 27721013
4. Data suggest that hunger, pleasantness of eating, and prospective food intake are down-regulated in older women and this is accompanied by up-regulation of blood levels of peptide YY; both age and sex of subject appear to have independent effects on energy intake. This study was conducted in London and is reported as preliminary evidence. PMID: 27264721
5. In extremely obese patients, fasting PYY3-36 concentrations were linked to systolic blood pressure, but not to other components of metabolic syndrome, suggesting divergence between pathways of blood pressure and glucose/body weight regulation. PMID: 27513679
6. expression of PYY and its NPY receptors on mouse islets and immortalised rodent and human beta-cells was examined. PMID: 27465830
7. Altogether, these results demonstrated a role of toll-like receptors in the modulation of Pyy expression and the importance of butyrate, a product of bacterial fermentation in regulation of microbial toll-like receptor-dependent sensing. PMID: 27405092
8. Data suggest that laparoscopic sleeve gastrectomy (LSG) for morbid obesity improves insulin resistance after either fast or slow feeding/eating; these findings suggest a negligible contribution of anorexigenic gut peptides GLP1 (glucagon-like peptide 1) and PYY (peptide YY) from intestinal L cells in response to LSG-induced weight loss. PMID: 27022941
9. Angiotensin II stimulates PYY secretion, in turn inhibiting epithelial anion fluxes, thereby reducing net fluid secretion into the colonic lumen. PMID: 27447725
10. These findings indicate that the mechanism underlying type 2 diabetes remission may be mediated by PYY. PMID: 27117413

12. Data suggest that endocrine responses differ between jejunal and gastric enteral feeding, with higher peak plasma CCK (cholecystokinin), PYY (peptide YY), and GLP-1/2 (glucagon-like peptides 1/2) concentrations being attained after jejunal feeding. PMID: 26762368
13. Data suggest that capsaicin, an appetite suppressant dietary supplement (here, administered via intraduodenal infusion), does not act via alteration of secretion of satiety hormones PYY (peptide YY) and GLP-1 (GLP-1). PMID: 26718419
14. Data suggest that, despite effects of acute sprint interval exercise (SIE) on oxygen consumption, appetite regulation, and brief up-regulation of plasma PYY, acute SIE does not affect energy intake of young men. PMID: 25494974
15. Plasma PYY and PP levels were significantly higher in HG [Hyperemesis gravidarum ] group. PMID: 25990478
16. Data suggest plasma PYY (peptide YY) and GLP1 (glucagon-like peptide 1) can be regulated by digestion-resistant diet factors; intake of soluble dietary fiber (prebiotic Fibersol-2) in a tea with meal up-regulated plasma PYY/GLP1 and decreased hunger. PMID: 25823991
17. Eating speed at breakfast did not affect postprandial ghrelin, GLP-1, PYY, hunger, and fullness values or daily energy and macronutrient intake. PMID: 25361054
18. These results indicate that circulating PYY may have buffering effects during the early stages of smoking cessation while ghrelin may confer increased risk of smoking relapse. PMID: 25127083
19. Data suggest secretion of PYY and GLP1 (glucagon-like peptide-1) can be altered by diet; plasma levels of PYY/GLP1 are increased during postprandial period after meal using Paleolithic diet principles (high in protein/plant matter; no cereals/dairy). PMID: 25661189
20. Intraduodenal lipid more potently stimulated PYY release when compared to intraduodenal protein. PMID: 25568079
21. data suggested that peptide YY expression is down-regulated by differentiation of monocytes to macrophages and proinflammatory stimuli. PMID: 24969624
22. Although the effect size of the positive association of PYY with obesity in women is small, and potentially negligible, it may in fact represent a protective response against significant weight gain PMID: 24743402
23. We critically discuss recent findings relating to the role of PYY in mediating the beneficial effects of bariatric surgery, the role of PYY in glucose homeostasis, the role of hepatoportal PYY in mediating its central physiological effects--{REVIEW} PMID: 24188711
