Calcium 315-322 huntingtin Mus musculus 28-31 15048901-0 2004 Paroxetine retards disease onset and progression in Huntingtin mutant mice. Paroxetine 0-10 huntingtin Mus musculus 52-62 15048901-1 2004 We report that administration of paroxetine, a widely prescribed antidepressant drug that acts by inhibiting reuptake of the neurotransmitter serotonin, suppresses the neurodegenerative process and increases the survival of huntingtin mutant mice, an animal model of Huntington"s disease (HD). Paroxetine 33-43 huntingtin Mus musculus 224-234 15048901-1 2004 We report that administration of paroxetine, a widely prescribed antidepressant drug that acts by inhibiting reuptake of the neurotransmitter serotonin, suppresses the neurodegenerative process and increases the survival of huntingtin mutant mice, an animal model of Huntington"s disease (HD). Serotonin 142-151 huntingtin Mus musculus 224-234 14713958-8 2004 Binding of caspase-2 to Htt is polyglutamine repeat-length dependent, and therefore may serve as a critical initiation step in HD cell death. polyglutamine 31-44 huntingtin Mus musculus 24-27 14999077-1 2004 Huntington"s disease (HD) is a devastating neurodegenerative disorder caused by a CAG repeat expansion encoding an extended polyglutamine tract in the huntingtin protein. polyglutamine 124-137 huntingtin Mus musculus 151-161 15033175-2 2004 We tested the hypothesis that enhanced NMDAR-mediated excitotoxicity is mediated by the mitochondrial-associated apoptotic pathway in cultured MSNs from YAC transgenic mice expressing full-length huntingtin (htt) with a polyglutamine (polyQ) expansion of 46 or 72 (YAC46 or YAC72). polyglutamine 220-233 huntingtin Mus musculus 208-211 14522959-2 2003 Early events in the disease cascade, which predate overt pathology in Hdh CAG knock-in mouse striatum, implicate enhanced N-methyl-D-aspartate (NMDA) receptor activation, with excitotoxity caused by aberrant Ca2+ influx. N-Methylaspartate 122-142 huntingtin Mus musculus 70-73 14667455-2 2004 The disease is caused by an unstable expanded trinucleotide (CAG) repeat encoding a polyglutamine stretch in the IT15 gene for huntingtin, a protein of unknown function. trinucleotide 46-59 huntingtin Mus musculus 113-117 14667455-2 2004 The disease is caused by an unstable expanded trinucleotide (CAG) repeat encoding a polyglutamine stretch in the IT15 gene for huntingtin, a protein of unknown function. trinucleotide 46-59 huntingtin Mus musculus 127-137 14667455-2 2004 The disease is caused by an unstable expanded trinucleotide (CAG) repeat encoding a polyglutamine stretch in the IT15 gene for huntingtin, a protein of unknown function.

GUANOSINE 5'-TRIPHOSPHATE P3-[1-(2-NITROPHENYL)ETHYL ESTER] 61-64 huntingtin Mus musculus 127-137 14667455-2 2004 The disease is caused by an unstable expanded trinucleotide (CAG) repeat encoding a polyglutamine stretch in the IT15 gene for huntingtin, a protein of unknown function. polyglutamine 84-97 huntingtin Mus musculus 113-117 14667455-2 2004 The disease is caused by an unstable expanded trinucleotide (CAG) repeat encoding a polyglutamine stretch in the IT15 gene for huntingtin, a protein of unknown function. polyglutamine 84-97 huntingtin Mus musculus 127-137 15105254-6 2004 The inheritance of polyglutamine-expanded huntingtin may promote neuronal degeneration in Huntington"s disease (HD), in part, by increasing MAOS. polyglutamine 19-32 huntingtin Mus musculus 42-52 14522959-2 2003 Early events in the disease cascade, which predate overt pathology in Hdh CAG knock-in mouse striatum, implicate enhanced N-methyl-D-aspartate (NMDA) receptor activation, with excitotoxity caused by aberrant Ca2+ influx. N-Methylaspartate 144-148 huntingtin Mus musculus 70-73 14522959-4 2003 Elevated levels of activated Ser(P)473-Akt are detected in extracts of Hdh(Q111/Q111) striatum and cultured mutant STHdh(Q111/Q111) striatal cells, compared with their wild type counterparts. Serine 29-32 huntingtin Mus musculus 71-74 12657678-8 2003 Transfection of cultured cells with mutant huntingtin revealed that an N-terminal huntingtin fragment (amino acids 1-208 plus a 120 glutamine repeat) caused a greater increase in caspase activity than did exon 1 huntingtin and longer huntingtin fragments.

Glutamine 100-109 huntingtin Mus musculus 150-160 12787055-6 2003 Neuropathological sequelae of gross brain and neuronal atrophy and huntingtin aggregates were delayed in creatine-treated R6/2 mice started at 6 weeks. Creatine 105-113 huntingtin Mus musculus 67-77 12706247-1 2003 Huntington"s disease (HD) is a neurodegenerative disorder caused by expansion of a polyglutamine tract in a protein called huntingtin. polyglutamine 83-96 huntingtin Mus musculus 123-133 12589027-2 2003 We show that the progression of neuropathological (formation of huntingtin inclusions and apoptotic protease activation), behavioral (motor dysfunction), and metabolic (glucose intolerance and tissue wasting) abnormalities in huntingtin mutant mice, an animal model of HD, are retarded when the mice are maintained on a dietary restriction (DR) feeding regimen resulting in an extension of their life span. Glucose 169-176 huntingtin Mus musculus 226-236 12588797-4 2003 Furthermore, cAMP levels in Hdh(Q111) striatum declined from an early age (10 weeks), and cAMP was significantly decreased in HD postmortem brain and lymphoblastoid cells, attesting to a chronic deficit in man. Cyclic AMP 13-17 huntingtin Mus musculus 28-31 12559971-7 2003 These results suggest that the mitochondrial calcium handling defects seen in Huntington"s disease cell lines and transgenic mice may be due, in part, to direct, deleterious effects of mutant huntingtin on mitochondria. Calcium 45-52 huntingtin Mus musculus 192-202 12554681-1 2003 Somatic instability of expanded HD CAG repeats that encode the polyglutamine tract in mutant huntingtin has been implicated in the striatal selectivity of Huntington"s disease (HD) pathology. polyglutamine 63-76 huntingtin Mus musculus 93-103 12554681-4 2003 The absence of Msh2 also eliminated striatal mutant huntingtin with somatically expanded glutamine tracts and caused an approximately 5 month delay in nuclear mutant protein accumulation, but did not alter the striatal specificity of this early phenotype. Glutamine 89-98 huntingtin Mus musculus 52-62 12554681-5 2003 Thus, somatic HD CAG instability appears to be a consequence of a striatal-selective disease process that accelerates the timing of an early disease phenotype, via expansion of the glutamine tract in mutant huntingtin. Glutamine 181-190 huntingtin Mus musculus 207-217 14653308-5 2003 5-HTT null mutants on the 129S6 background showed reduced 5-HT(1A) receptor binding (as measured by quantitative autoradiography) and reduced 5-HT(1A) receptor function (as measured by 8-OH-DPAT-induced hypothermia). 8-Hydroxy-2-(di-n-propylamino)tetralin 185-194 huntingtin Mus musculus 2-5 12913073-0 2003 Abnormal association of mutant huntingtin with synaptic vesicles inhibits glutamate release. Glutamic Acid 74-83 huntingtin Mus musculus 31-41 12913073-1 2003 In Huntington disease (HD), polyglutamine expansion causes the disease protein huntingtin to aggregate and accumulate in the nucleus and cytoplasm. polyglutamine 28-41 huntingtin Mus musculus 79-89 12891671-3 2003 Because the tetracyclines have also been reported to inhibit aggregation in other amyloid disorders, we have investigated their ability to inhibit huntingtin aggregation and further explored their efficacy in preclinical mouse trials. Tetracyclines 12-25 huntingtin Mus musculus 147-157 12891671-4 2003 We show that tetracyclines are potent inhibitors of huntingtin aggregation in a hippocampal slice culture model of HD at an effective concentration of 30 microM. Tetracyclines 13-26 huntingtin Mus musculus 52-62 12890790-1 2003 Huntington"s disease (HD) is caused by a polyglutamine expansion in the disease protein huntingtin. polyglutamine 41-54 huntingtin Mus musculus 88-98 12890790-2 2003 The polyglutamine expansion causes huntingtin to interact abnormally with a number of proteins. polyglutamine 4-17 huntingtin Mus musculus 35-45 12657678-8 2003 Transfection of cultured cells with mutant huntingtin revealed that an N-terminal huntingtin fragment (amino acids 1-208 plus a 120 glutamine repeat) caused a greater increase in caspase activity than did exon 1 huntingtin and longer huntingtin fragments. Glutamine 132-141 huntingtin Mus musculus 82-92 12657678-8 2003 Transfection of cultured cells with mutant huntingtin revealed that an N-terminal huntingtin fragment (amino acids 1-208 plus a 120 glutamine repeat) caused a greater increase in caspase activity than did exon 1 huntingtin and longer huntingtin fragments. Glutamine 132-141 huntingtin Mus musculus 82-92 12657678-8 2003 Transfection of cultured cells with mutant huntingtin revealed that an N-terminal huntingtin fragment (amino acids 1-208 plus a 120 glutamine repeat) caused a greater increase in caspase activity than did exon 1 huntingtin and longer huntingtin fragments. Glutamine 132-141 huntingtin Mus musculus 82-92 12089530-5 2002 Thus, mitochondrial calcium abnormalities occur early in HD pathogenesis and may be a direct effect of mutant huntingtin on the organelle. Calcium 20-27 huntingtin Mus musculus 110-120 12586550-5 2002 Disrupted expression of a subset of transcription factors in pancreatic beta cells by a polyglutamine expansion tract in the huntingtin protein selectively impairs insulin gene expression to result in insulin deficiency and diabetes. polyglutamine 88-101 huntingtin Mus musculus 125-135 12417652-1 2002 Aggregates of green fluorescent protein (GFP)-fused truncated N-terminal huntingtin containing abnormally long polyglutamine tracts (150 repeats of glutamine residue) were purified from an ecdysone-inducible mutant neuro2A cell line (HD150Q-28) by using a fluorescence-activated cell sorter. polyglutamine 111-124 huntingtin Mus musculus 73-83 12417652-1 2002 Aggregates of green fluorescent protein (GFP)-fused truncated N-terminal huntingtin containing abnormally long polyglutamine tracts (150 repeats of glutamine residue) were purified from an ecdysone-inducible mutant neuro2A cell line (HD150Q-28) by using a fluorescence-activated cell sorter. Glutamine 115-124 huntingtin Mus musculus 73-83 12217951-1 2002 The hallmark striatal neurodegeneration of Huntington"s disease (HD) is first triggered by a dominant property of the expanded glutamine tract in mutant huntingtin that increases in severity with glutamine size. Glutamine 127-136 huntingtin Mus musculus 153-163 12217951-1 2002 The hallmark striatal neurodegeneration of Huntington"s disease (HD) is first triggered by a dominant property of the expanded glutamine tract in mutant huntingtin that increases in severity with glutamine size.

Glutamine 172-181 huntingtin Mus musculus 28-38 12223539-8 2002 However, in HD, cleavage of mutant htt would release N-terminal fragments with the potential for increased toxicity and accumulation caused by the presence of the expanded polyglutamine tract. polyglutamine 172-185 huntingtin Mus musculus 35-38 12193654-15 2002 Here we show that structural analyses of soluble huntingtin exon 1 fusion proteins with 16 to 46 glutamine residues reveal extended structures with random coil characteristics and no evidence for a global conformational change above 36 glutamines. Glutamine 97-106 huntingtin Mus musculus 49-59 12193654-16 2002 An antibody (MW1) Fab fragment, which recognizes full-length huntingtin in mouse brain sections, binds specifically to exon 1 constructs containing normal and expanded poly(Gln) tracts, with affinity and stoichiometry that increase with poly(Gln) length. poly(gln) 168-177 huntingtin Mus musculus 61-71 12193654-16 2002 An antibody (MW1) Fab fragment, which recognizes full-length huntingtin in mouse brain sections, binds specifically to exon 1 constructs containing normal and expanded poly(Gln) tracts, with affinity and stoichiometry that increase with poly(Gln) length. poly(gln) 237-246 huntingtin Mus musculus 61-71 12165554-1 2002 Previous analyses of gene expression in a mouse model of Huntington"s disease (R6/2) indicated that an N-terminal fragment of mutant huntingtin causes downregulation of striatal signaling genes and particularly those normally induced by cAMP and retinoic acid. Cyclic AMP 237-241 huntingtin Mus musculus 133-143 12165554-1 2002 Previous analyses of gene expression in a mouse model of Huntington"s disease (R6/2) indicated that an N-terminal fragment of mutant huntingtin causes downregulation of striatal signaling genes and particularly those normally induced by cAMP and retinoic acid.

Isoflurane 30-40 huntingtin Mus musculus 66-76 21059370-2 2011 We hypothesized that isoflurane will have similar effects on the polyglutamine huntingtin protein and will cause alterations in intracellular calcium homeostasis. Isoflurane 21-31 huntingtin Mus musculus 79-89 21059370-3 2011 We tested this hypothesis in striatal cells from the expanded glutamine huntingtin knock-in mouse (STHdh(Q111/Q111)) and wild type (STHdh(Q7/Q7)) striatal neurons.
