Peptide YY3-36 (PYY) has emerged as an important signal in the gut-brain axis, with peripherally administered PYY affecting feeding and brain function. For these effects to be direct, PYY would have to cross the blood-brain barrier (BBB). Here, we determined the permeability of the BBB to PYY radioactively labeled with 131I (I-PYY). Multiple-time regression analysis showed the unidirectional in...
ATP-binding cassette protein G1 (ABCG1) is important for the formation of HDL. However, the biochemical properties of ABCG1 have not been reported, and the mechanism of how ABCG1 is involved in HDL formation remains unclear. We established a procedure to express and purify human ABCG1 using the suspension-adapted human cell FreeStyle293-F. ABCG1, fused at the C terminus with green fluorescent p...
Neuropeptide Y (NPY) is the only member of its peptide family that has been isolated from the mammalian CNS. We have recently found that two different NPY-related molecules are present in the CNS of a cyclostome, the river lamprey (Lampetra fluviatilis) (Söderberg et al., 1991). Here we show that this is also true for the rat CNS, by demonstrating expression of peptide YY (PYY) mRNA in brainste...
Cholecystokinin (CCK)-induced suppression of feeding is mediated by vagal sensory neurons that are destroyed by the neurotoxin capsaicin (CAP). Here we determined whether CAP-sensitive neurons mediate anorexic responses to intravenous infusions of gut hormones peptide YY-(3-36) [PYY-(3-36)] and glucagon-like peptide-1 (GLP-1). Rats received three intraperitoneal injections of CAP or vehicle (VE...
The spontaneous mouse mutation “thrombocytopenia and cardiomyopathy” (trac) causes macrothrombocytopenia, prolonged bleeding times, anemia, leukopenia, infertility, cardiomyopathy, and shortened life span. Homozygotes show a 20-fold decrease in platelet numbers and a 3-fold increase in platelet size with structural alterations and functional impairments in activation and aggregation. Megakaryoc...
OBJECTIVE In a recent article in Arteriosclerosis, Thrombosis, and Vascular Biology, it was reported that ATP-binding cassette transporter G1 (ABCG1) containing leucine at position 550 (ABCG1-L550) was localized to the plasma membrane, whereas ABCG1-P550 (proline at position 550) was intracellular. Because the published data on the subcellular localization of ABCG1 are controversial, we perform...
OBJECTIVE Alterations of pancreatic β-cell cholesterol content may contribute to β-cell dysfunction. Two important determinants of intracellular cholesterol content are the ATP-binding cassette (ABC) transporters A1 (ABCA1) and -G1 (ABCG1). Whether genetic variation in ABCA1 and ABCG1 predicts risk of type 2 diabetes in the general population is unknown. RESEARCH DESIGN AND METHODS We tested ...
ATP-binding cassette transporter G1 (ABCG1) is a member of the ABC transporter family and regulates cellular cholesterol homeostasis. It has important roles in cholesterol homeostasis and tumor immunity, which has, however, not been reported in lung cancer. The present study showed that ABCG1 protein is upregulated in lung cancer compared with adjacent normal tissues and furthermore, aberrant A...
ATP-binding cassette transporter G1 (ABCG1) plays a role in the intracellular transport of cholesterol. Invariant NKT (iNKT) cells are a subpopulation of T lymphocytes that recognize glycolipid Ags. In this study, we demonstrate that ABCG1 regulates iNKT cell development and functions in a cell-intrinsic manner. Abcg1(-/-) mice displayed reduced frequencies of iNKT cells in thymus and periphery...
مقدمه: pyy، پپتید روده ای است که نقش اساسی در تنظیم دریافت غذا و هوموستاز انرژی دارد. با این حال تغییرات pyy و رابطه آن با احساس سیری پس از سازگاری با تمرینات هوازی در مردان ناشناخته است. هدف این پژوهش بررسی اثر هشت هفته تمرین هوازی بر احساس سیری و میزان pyy پلاسمای زمان استراحت و ناشی از ورزش وامانده ساز در مردان دانشجو بود. مواد و روش ها: 23 مرد (میانگین سنی12/2 ± 58/19 سال، شاخص توده بدنی 7/...
