Adenosine Triphosphate 177-180 insulin receptor Rattus norvegicus 38-54 2484434-6 1989 As a whole our data indicate that the insulin receptor kinase is involved in the generation of an early (glucose transport) and late (aminoacid uptake) response to insulin. Glucose 105-112 insulin receptor Rattus norvegicus 38-54 2484434-7 1989 Further, conformational changes in phosphotyrosine containing domains of the insulin receptor appear to modulate insulin"s biological effects. Phosphotyrosine 35-50 insulin receptor Rattus norvegicus 77-93 2642422-9 1989 This is probably due to reduced affinity for the insulin receptor, since it had 2.5% of insulin"s ability to both bind to the receptor and stimulate glucose oxidation.

Cyproterone Acetate 106-125 insulin receptor Rattus norvegicus 37-53 5049308-3 1972 The results indicate that the defect responsible for this insulin-resistant state exists in a step subsequent to insulin binding, possibly in transmission of the insulin-receptor "signal" since insensitivity occurs under conditions where glucose transport and oxidative processes are not apparently impaired. Glucose 238-245 insulin receptor Rattus norvegicus 162-178 849730-5 1977 Conclusions from these studies are that both disorders in coupling of insulin-receptor complexes to glucose transport systems and intracellular glucose metabolism play major roles in the insulin insensitivity of adipocytes from fasted rats, whereas, in adipocytes from refed rats, intracellular glucose metabolism, rather than glucose transport, is mainly involved in restoring insulin sensitivity.

Indomethacin 0-12 insulin receptor Rattus norvegicus 49-65 2249624-6 1990 Binding studies at 15 C in the presence of potassium cyanide revealed that this effect was associated with an increase in insulin receptor affinity. Potassium Cyanide 43-60 insulin receptor Rattus norvegicus 122-138 2249624-13 1990 We conclude that 1) low concentrations of vanadate (less than 200 microM) increase insulin receptor affinity and consequent insulin uptake in rat adipocytes; 2) the excess cell-associated insulin exists largely as intact hormone; and 3) the increased binding at low insulin concentrations results in an apparent increase in insulin sensitivity. Vanadates 42-50 insulin receptor Rattus norvegicus 83-99 1701386-2 1990 (a) Polylysine stimulated both tyrosine and serine phosphorylation of the insulin receptor and of additional proteins present in lectin-purified membrane preparations from rat liver.

Carbohydrates 27-39 insulin receptor Rattus norvegicus 54-70 2269579-6 1990 With increasing palmitate concentration, a dose-dependent decline in cell-surface insulin receptor binding was observed. Palmitates 16-25 insulin receptor Rattus norvegicus 82-98 2269579-11 1990 This decrease was proportional to the reduction in cell-surface insulin receptor density at palmitate concentrations of 0.05-0.5 mM, but was disproportionally greater at higher fatty acid concentrations.

Threonine 63-72 insulin receptor Rattus norvegicus 23-39 2354998-9 1990 These findings suggest that in starved, insulin-resistant animals, an increase in hepatic protein kinase C activity is associated with increased Ser/Thr phosphorylation which in turn decreases autophosphorylation and function of the insulin receptor kinase. Serine 145-148 insulin receptor Rattus norvegicus 233-249 2354998-9 1990 These findings suggest that in starved, insulin-resistant animals, an increase in hepatic protein kinase C activity is associated with increased Ser/Thr phosphorylation which in turn decreases autophosphorylation and function of the insulin receptor kinase.

Metformin 29-38 insulin receptor Rattus norvegicus 47-63 2161833-7 1990 In the latter experiment, cells expressing HIR delta ex16 receptors exhibit tyrosine phosphorylation of insulin receptor beta-subunits as well as of pp 185, a putative substrate of the receptor. Tyrosine 76-84 insulin receptor Rattus norvegicus 104-120 2189597-6 1990 In contrast, both sequential and CDMO treatments prevented the insulin receptor alterations induced by the CD diet. cdmo 33-37 insulin receptor Rattus norvegicus 63-79 2189597-6 1990 In contrast, both sequential and CDMO treatments prevented the insulin receptor alterations induced by the CD diet. Cadmium 33-35 insulin receptor Rattus norvegicus 63-79 2189597-7 1990 These data demonstrate that the CD diet-induced insulin receptor alterations occur concurrently with the induction of ODC activity. Cadmium 32-34 insulin receptor Rattus norvegicus 48-64 2189597-8 1990 But insulin receptor changes and the increased ODC activity are affected differently by CDMO treatment, suggesting that their induction by the CD diet is through distinct mechanisms and only the receptor alterations correspond with the tumor-promoting action of CD diet regimen. Cadmium 88-90 insulin receptor Rattus norvegicus 4-20 1693770-0 1990 Location of phosphotyrosine-containing proteins by immunocytochemistry in the rat forebrain corresponds to the distribution of the insulin receptor. Phosphotyrosine 12-27 insulin receptor Rattus norvegicus 131-147 1693770-9 1990 Importantly, the distribution of the areas positive for phosphotyrosine agreed to a remarkable extent with the distribution of the brain insulin receptor, which itself has tyrosine kinase activity. Phosphotyrosine 56-71 insulin receptor Rattus norvegicus 137-153 1693770-10 1990 These findings suggest a relationship between the insulin receptor and the increased phosphotyrosine content of these neurons and support the concept that the brain insulin receptor is active in vivo. Phosphotyrosine 85-100 insulin receptor Rattus norvegicus 50-66 1693770-10 1990 These findings suggest a relationship between the insulin receptor and the increased phosphotyrosine content of these neurons and support the concept that the brain insulin receptor is active in vivo.

Tyrosine 62-70 insulin receptor Rattus norvegicus 13-29 1691994-6 1990 Because anti-insulin-receptor antibodies immunoprecipitated a tyrosine-phosphorylated 95,000-Mr protein, this protein must be the beta-subunit of the insulin receptor; i.e., the beta-subunit of the insulin receptor and two other proteins were phosphorylated at tyrosine residues in vivo by insulin injection. Tyrosine 62-70 insulin receptor Rattus norvegicus 150-166 1691994-6 1990 Because anti-insulin-receptor antibodies immunoprecipitated a tyrosine-phosphorylated 95,000-Mr protein, this protein must be the beta-subunit of the insulin receptor; i.e., the beta-subunit of the insulin receptor and two other proteins were phosphorylated at tyrosine residues in vivo by insulin injection. Tyrosine 62-70 insulin receptor Rattus norvegicus 198-214 1691994-6 1990 Because anti-insulin-receptor antibodies immunoprecipitated a tyrosine-phosphorylated 95,000-Mr protein, this protein must be the beta-subunit of the insulin receptor; i.e., the beta-subunit of the insulin receptor and two other proteins were phosphorylated at tyrosine residues in vivo by insulin injection. Tyrosine 261-269 insulin receptor Rattus norvegicus 13-29 1966886-7 1990 Insulin-induced tyrosine kinase activity of partially purified insulin receptor measured using poly-glutyr as substrate was also lower in cells from diabetic rats (normal:1.4 +/- 0.6-fold; diabetic 0.5 +/- 0.3-fold above baseline; (p less than 0.05). poly-glutyr 95-106 insulin receptor Rattus norvegicus 63-79 1691994-6 1990 Because anti-insulin-receptor antibodies immunoprecipitated a tyrosine-phosphorylated 95,000-Mr protein, this protein must be the beta-subunit of the insulin receptor; i.e., the beta-subunit of the insulin receptor and two other proteins were phosphorylated at tyrosine residues in vivo by insulin injection. Tyrosine 261-269 insulin receptor Rattus norvegicus 150-166 1691994-6 1990 Because anti-insulin-receptor antibodies immunoprecipitated a tyrosine-phosphorylated 95,000-Mr protein, this protein must be the beta-subunit of the insulin receptor; i.e., the beta-subunit of the insulin receptor and two other proteins were phosphorylated at tyrosine residues in vivo by insulin injection. Tyrosine 261-269 insulin receptor Rattus norvegicus 198-214 1691994-7 1990 These data suggest that the tyrosine phosphorylation and tyrosine kinase activity of the insulin receptor may have important roles in in vivo insulin action. Tyrosine 28-36 insulin receptor Rattus norvegicus 89-105 2180315-4 1990 In wheat germ agglutinin purified receptors, 125I-labeled porcine insulin binding, basal and insulin-stimulated insulin receptor kinase activities for both the autophosphorylation of the beta-subunit and the phosphorylation of the artificial substrate poly (Glu-Tyr) 4:1, were found identical in diabetic and control rats, treated or not with vanadate. Iodine-125 45-49 insulin receptor Rattus norvegicus 112-128 1691570-5 1990 Basal as well as insulin-stimulated tyrosine kinase activity per insulin receptor was higher in the high-fat fed group, accompanied by increased autophosphorylation of the beta-subunit of the receptor and higher proportion of tyrosine-phosphorylated insulin receptors. Tyrosine 36-44 insulin receptor Rattus norvegicus 65-81 1691570-6 1990 In contrast, both in the skeletal muscle and the liver the insulin-stimulated tyrosine kinase activity per insulin receptor was significantly lower in high-fat fed animals, accompanied by diminished autophosphorylation of the beta-subunit of the receptor and lower proportion of tyrosine-phosphorylated receptors. Tyrosine 78-86 insulin receptor Rattus norvegicus 107-123 2180315-4 1990 In wheat germ agglutinin purified receptors, 125I-labeled porcine insulin binding, basal and insulin-stimulated insulin receptor kinase activities for both the autophosphorylation of the beta-subunit and the phosphorylation of the artificial substrate poly (Glu-Tyr) 4:1, were found identical in diabetic and control rats, treated or not with vanadate. poly (glu-tyr) 4 252-268 insulin receptor Rattus norvegicus 112-128 2180315-4 1990 In wheat germ agglutinin purified receptors, 125I-labeled porcine insulin binding, basal and insulin-stimulated insulin receptor kinase activities for both the autophosphorylation of the beta-subunit and the phosphorylation of the artificial substrate poly (Glu-Tyr) 4:1, were found identical in diabetic and control rats, treated or not with vanadate. Vanadates 343-351 insulin receptor Rattus norvegicus 112-128 2180315-6 1990 Thus, in that model of non-insulin-dependent diabetes, 1) oral vanadate exerts a corrective insulin-like effect on impaired insulin action both at the level of liver and peripheral tissues, 2) impaired insulin action with no alteration of the insulin receptor tyrosine kinase is observed in the liver of untreated rats, and 3) corrective effect of vanadate on liver glucose metabolism is probably distal to the insulin receptor kinase activity. Vanadates 63-71 insulin receptor Rattus norvegicus 411-427 2262933-14 1990 The data suggests that (i) fundamental differences exist between the receptor state in intact cells and isolated plasma membranes and (ii) that a disulphide-rich region within the insulin receptor, other than the previously reported class I and class II disulphide bridges, is critical for insulin binding and cellular response. disulphide 146-156 insulin receptor Rattus norvegicus 180-196 2154464-15 1990 The insulin receptor kinase is a likely candidate as its activity is markedly enhanced either by insulin (plus H2O2) or by H2O2/vanadate. Hydrogen Peroxide 111-115 insulin receptor Rattus norvegicus 4-20 2154464-15 1990 The insulin receptor kinase is a likely candidate as its activity is markedly enhanced either by insulin (plus H2O2) or by H2O2/vanadate. Hydrogen Peroxide 123-127 insulin receptor Rattus norvegicus 4-20 2154464-15 1990 The insulin receptor kinase is a likely candidate as its activity is markedly enhanced either by insulin (plus H2O2) or by H2O2/vanadate. Vanadates 128-136 insulin receptor Rattus norvegicus 4-20 2153971-7 1990 The effects of this agent reveal a striking difference in insulin receptor-mediated stimulation of glucose transport between 3T3-L1 fatty fibroblasts and the mature rat adipocyte. Glucose 99-106 insulin receptor Rattus norvegicus 58-74 2153102-3 1990 In the presence of insulin, selenate enhances insulin receptor kinase activity and phosphorylations of insulin-stimulated tyrosyl phosphoproteins.

Glucose 198-205 insulin receptor Rattus norvegicus 72-88 2158467-3 1990 Autophosphorylation of the insulin receptor beta subunit was increased in liver receptors prepared from rats at the end of the glucose clamp compared to rats in the basal state both in the absence of insulin in vitro (109% increase, p less than 0.001) and after in vitro stimulation with 10(-7) mol/l insulin (clamped vs fasted; 96% increase, p less than 0.001).

Serotonin 71-80 insulin receptor Rattus norvegicus 0-16 2196058-1 1990 Insulin receptor activity and its relationship with catecholamines and serotonin were investigated in rat brain using Triton X-100 extracts from total membranes, synaptosomes and choroid plexus in experimental hypothyroidism and hyperthyroidism. Octoxynol 118-130 insulin receptor Rattus norvegicus 0-16 2196058-2 1990 Insulin receptor activity was assessed by binding to [125I]insulin and catecholamines by high performance liquid chromatography. Catecholamines 71-85 insulin receptor Rattus norvegicus 0-16 2201297-1 1990 Insulin receptor activity and its relationship with catecholamines in rat young, middle aged and old red blood cells were investigated in experimental hypothyroidism and hyperthyroidism. Catecholamines 52-66 insulin receptor Rattus norvegicus 0-16 2201297-2 1990 In control animals, a loss of insulin receptor activity was found with cellular ageing and increased levels of norepinephrine, epinephrine and glycosylated hemoglobin.
