Serotonin 123-132 monoamine oxidase A Homo sapiens 21-25 18437281-1 2008 Monoamine oxidase A (MAOA) abnormality has been suggested as a crucial factor in the pathogenesis of mood disorder, because MAOA is associated with the metabolism of monoamines such as serotonin and norepinephrine.

Serotonin 185-194 monoamine oxidase A Homo sapiens 124-128 18596609-1 2008 The X-linked monoamine oxidase A (MAO A) gene, coding for an enzyme especially involved in the serotonin catabolism, presents a well-characterized functional polymorphism (long and short variants) in the promoter region that alters the transcriptional activity of the gene and hence the function of the corresponding proteins. Serotonin 95-104 monoamine oxidase A Homo sapiens 34-39 20641420-2 2004 MAO-A preferentially oxidizes serotonin and noradrenaline, whereas MAO-B preferentially oxidizes phenethylamine. Serotonin 30-39 monoamine oxidase A Homo sapiens 0-5 18501009-1 2008 BACKGROUND: Monoamine oxidase A (MAOA) is a mitochondrial enzyme involved in degrading several different biological amines, including serotonin. Serotonin 134-143 monoamine oxidase A Homo sapiens 12-31 18501009-1 2008 BACKGROUND: Monoamine oxidase A (MAOA) is a mitochondrial enzyme involved in degrading several different biological amines, including serotonin. Serotonin 134-143 monoamine oxidase A Homo sapiens 33-37 18463263-1 2008 The genetic deletion of monoamine oxidase A (MAO A), an enzyme that breaks down the monoamine neurotransmitters norepinephrine, serotonin, and dopamine, produces aggressive phenotypes across species. Serotonin 128-137 monoamine oxidase A Homo sapiens 24-43 18463263-1 2008 The genetic deletion of monoamine oxidase A (MAO A), an enzyme that breaks down the monoamine neurotransmitters norepinephrine, serotonin, and dopamine, produces aggressive phenotypes across species. Serotonin 128-137 monoamine oxidase A Homo sapiens 45-50 18294618-2 2008 The X-linked Mono-Amine Oxidase A (MAO A) gene, coding for an enzyme especially involved in the serotonin (5-HT) catabolism, presents a well-characterized functional polymorphism consisting in a variable number of tandem repeats (VNTR) in the promoter region with high activity and low activity variants. Serotonin 96-105 monoamine oxidase A Homo sapiens 35-40 18388730-1 2008 Monoamine oxidase A (MAOA) enzymatically degrades biogenic amines such as norepinephrine, dopamine, and serotonin, and plays a key role in the regulation of their neurotransmission. Serotonin 104-113 monoamine oxidase A Homo sapiens 0-19 18388730-1 2008 Monoamine oxidase A (MAOA) enzymatically degrades biogenic amines such as norepinephrine, dopamine, and serotonin, and plays a key role in the regulation of their neurotransmission. Serotonin 104-113 monoamine oxidase A Homo sapiens 21-25 18366702-7 2008 RESULTS: Our analysis found that significant downregulation of MAO-A, the enzyme that metabolizes serotonin, occurred in multiple tissues from humans, rodents, and fish. Serotonin 98-107 monoamine oxidase A Homo sapiens 63-68 18258310-5 2008 We propose that the MAOA-L, by causing an ontogenic excess of 5-hydroxytryptamine, labilizes critical neural circuitry for social evaluation and emotion regulation (the "socioaffective scaffold"), thereby amplifying the effects of adverse early-life experience and creating deleterious sociocognitive biases. Serotonin 62-81 monoamine oxidase A Homo sapiens 20-24 18227761-1 2008 BACKGROUND: The monoamine oxidase-A (MAOA) gene plays a vital role in the metabolism of neurotransmitters, e.g, serotonin, norepinephrine, and dopamine. Serotonin 112-121 monoamine oxidase A Homo sapiens 16-35 18227761-1 2008 BACKGROUND: The monoamine oxidase-A (MAOA) gene plays a vital role in the metabolism of neurotransmitters, e.g, serotonin, norepinephrine, and dopamine. Serotonin 112-121 monoamine oxidase A Homo sapiens 37-41 18405062-6 2008 In addition, when TPH-cc and MAOA-4 were combined as "high 5HT" genotypes, a correlative increase in PSL was observed with the increase in the number of "high 5HT" genotypes. Serotonin 59-62 monoamine oxidase A Homo sapiens 29-33 18405062-6 2008 In addition, when TPH-cc and MAOA-4 were combined as "high 5HT" genotypes, a correlative increase in PSL was observed with the increase in the number of "high 5HT" genotypes. Serotonin 159-162 monoamine oxidase A Homo sapiens 29-33 17884271-5 2008 The present results suggest that high-activity MAO-A genotypes possibly by consecutively decreased serotonin and/or norepinephrine availability negatively influence antidepressant treatment response during the first six weeks of pharmacological treatment in female patients with Major Depression. Serotonin 99-108 monoamine oxidase A Homo sapiens 47-52 17721552-0 2007 Methylene blue and serotonin toxicity: inhibition of monoamine oxidase A (MAO A) confirms a theoretical prediction. Serotonin 19-28 monoamine oxidase A Homo sapiens 53-72 17721552-0 2007 Methylene blue and serotonin toxicity: inhibition of monoamine oxidase A (MAO A) confirms a theoretical prediction. Serotonin 19-28 monoamine oxidase A Homo sapiens 74-79 17721552-10 2007 This inhibition of MAO A would be expected to lead to perturbations of 5-hydroxytryptamine metabolism and hence account for ST occurring when administered to patients on SSRI treatment.
