Tryptophan 77-80 gastrin Homo sapiens 105-112 6161125-4 1981 To test this hypothesis, we have synthesized an oligodeoxynucleotide (oligo II) complementary to the region of gastrin mRNA coding for Trp-Met-Asp-Phe and have compared its effectiveness as a hybridization probe and as a primer for the synthesis of gastrin-specific cDNA with another oligonucleotide (oligo I) complementary to the region of gastrin mRNA coding for Trp-Met-Glu-Glu. Tryptophan 135-138 gastrin Homo sapiens 111-118 3953532-5 1986 Only phenylalanine and tryptophan produced significant stimulation of serum gastrin levels with peak increases above basal occurring 30 min after administration (p less than 0.05). Tryptophan 23-33 gastrin Homo sapiens 76-83 3953532-6 1986 It is concluded that: aspartic acid, leucine and glycine produced no significant changes in LES pressure or serum gastrin level; tryptophan and phenylalanine significantly increased serum gastrin concentration; tryptophan significantly decreased LES pressure whereas phenylalanine had no effect; the mechanism of inhibition of LES pressure by tryptophan is not defined and may be mediated by neural or hormonal pathways possibly involving a duodenal receptor. Tryptophan 129-139 gastrin Homo sapiens 188-195 6806140-4 1982 We conclude that a major part of the acid-stimulating action of mixed amino acid solution can be explained by the aromatic amino acids, phenylalanine and tryptophan, which are also the most potent stimulants of gastrin and pancreatic polypeptide release. Tryptophan 154-164 gastrin Homo sapiens 211-218 1523164-5 1992 Changing the peptide bond between Trp and Leu residues to a -omega(CH2-NH)- bond resulted in a compound which also bound to gastrin receptors (Kd approximately 10 nM) but presented agonist activity on acid secretion in the rat. Tryptophan 34-37 gastrin Homo sapiens 124-131 1773057-4 1991 We found that pairs of arginine residues flanking gastrin 34, the typical processing site sequence of all other preprogastrins and many peptide hormones, were arginines in the bovine preprogastrin, but the first basic amino acid pair had changed to Arg-Trp (57-58 residues) instead of Arg-Arg in the feline preprogastrin. Tryptophan 253-256 gastrin Homo sapiens 50-57 6806140-2 1982 Phenylalanine and tryptophan were significantly more potent stimulants of gastric acid secretion and of pancreatic polypeptide and gastrin release than any of the other amino acids tested. Tryptophan 18-28 gastrin Homo sapiens 131-138 22855967-0 2004 (111)In/(68)Ga-Labeled DOTA conjugated cyclo[gamma-d-Glu-Ala-Tyr-d-Lys]-Trp-Nle-Asp-Phe-NH2 (cyclo-MG2), a minigastrin analog The three subtypes of the cholecystokinin (CCK) receptors (CCKR) belong to the G-protein coupled receptor family and are classified (CCK1R, CCK2R and CCK2i4svR) on the basis of their affinities for the CCK and the gastrin peptides, differential distribution in the tissues and molecular structure (1). Tryptophan 72-75 gastrin Homo sapiens 111-118 738695-3 1978 It was found to be absolutely identical with a "modified tryptophan" which was isolated after the total synthesis of a gastrin analogue; Nin-tert-butyl-tryptophan peptides are formed as the main products of a tert-butylation reaction, the mechanism of which is not very clear yet. Tryptophan 57-67 gastrin Homo sapiens 119-126 88048-2 1979 The nucleotide sequence of the oligonucleotide, d(C-T-C-C-T-C-C-A-T-C-C-A), was deduced from the unique amino acid sequence Trp-Met-Glu-Glu of gastrin. Tryptophan 124-127 gastrin Homo sapiens 143-150 21362032-8 2011 Plasma gastrin level also rose significantly during treatment with omeprazole plus melatonin or Trp, but it was also significantly increased in patients treated with omeprazole plus placebo. Tryptophan 96-99 gastrin Homo sapiens 7-14 22204799-8 2011 Plasma gastrin and leptin levels showed a significant rise over initial values in patients treated with omeprazole and placebo, MT or TRP while plasma ghrelin levels were not significantly affected by these treatments. Tryptophan 134-137 gastrin Homo sapiens 7-14 11000005-1 2000 The two hormones cholecystokinin and gastrin share the same C-terminal sequence of amino acids, namely Gly(29)-Trp(30)-Met(31)-Asp(32)-Phe(33)-NH(2). Tryptophan 111-114 gastrin Homo sapiens 37-44 20443220-9 2010 Plasma gastrin levels were raised in subjects given melatonin or tryptophan plus ASA, but not in those with ASA alone. Tryptophan 65-75 gastrin Homo sapiens 7-14 20443220-10 2010 We conclude that melatonin and its precursor tryptophan given orally significantly reduce gastric lesions induced by ASA possibly due to (a) direct gastroprotective action of exogenous melatonin or that generated from tryptophan and (b) gastrin released from the gastric mucosa by melatonin or tryptophan. Tryptophan 45-55 gastrin Homo sapiens 237-244 19552764-5 2009 Moreover, plasma gastrin, ghrelin, leptin and insulin levels under fasting and postprandial conditions were significantly higher in LC subjects than in healthy controls and they further rose significantly after oral application of melatonin or Trp. Tryptophan 244-247 gastrin Homo sapiens 17-24 17950490-3 2007 The C-terminal conformation of [Nle(15)] gastrin-17 contained a short alpha-helix spanning the Ala(11)-Trp(14) sequence and an inverse gamma-turn centered on Nle(15) while that of [Tyr(9)-SO(3)] cholecystokinin-15 contained a short 3(10) helix spanning its Met(10) to Met(13) sequence and an inverse gamma-turn centered on Asp(14). Tryptophan 103-106 gastrin Homo sapiens 41-48 17698249-4 2007 The conformation of [Nle(15)] gastrin-17 consisted of two short helices between Leu(5)-Glu(9) and Ala(11)-Trp(14), with the one helix terminating in a type I beta-turn spanning Gly(13)-Asp(16). Tryptophan 106-109 gastrin Homo sapiens 30-37 10541353-7 1999 For this purpose, a variety of CCK/gastrin-related peptides, all having in common the COOH-terminal CCK-receptor binding tetrapeptide sequence Trp-Met-Asp-PheNH2 or derivatives thereof, were studied. Tryptophan 143-146 gastrin Homo sapiens 35-42 9578981-1 1998 The neuroendocrine peptides cholecystokinin (CCK) and gastrin, originally identified in mammals, are characterized by a common amidated C-terminal tetrapeptide sequence, Trp-Met-Asp-Phe.NH2, which also constitutes the minimal structure necessary for biological activity of both. Tryptophan 170-173 gastrin Homo sapiens 54-61 9392446-6 1997 L-tryptophan, which significantly elevated the plasma melatonin by about 3-5-fold, also reduced the stress and I/R-induced lesions and blood levels of free radicals, while increasing the GBF, DNA synthesis, and plasma gastrin levels. Tryptophan 0-12 gastrin Homo sapiens 218-225 10751901-11 1999 The gastric phase (hydrochloric acid and pepsinogen secretions) is activated by gastrin, histamine and acetilcholine which respond to both dietary-amino acids (tryptophan and phenylalanine) and mechanic distention of stomach.
