BACKGROUND: Metabolic syndrome may be related to folate's pharmacogenetically regulated metabolism and atypical antipsychotic (AAP) exposure.AIMS: We examined folate supplementation on metabolic measures, endothelial functioning (Reactive Hyperemia Index (RHI)), and global methylation in AAP-treated schizophrenia subjects meeting NCEP-ATP-III-a metabolic...

PMID: 26770364
Int J Clin Exp Med. 2015 Oct 15;8(10):17739-47. eCollection 2015.

Catechol-O-methyltransferase (COMT) 158 G/A gene polymorphism seem to associate with lung cancer, but the results are inconclusive. This meta-analysis aims to investigate the association between COMT 158 G/A gene polymorphism and lung cancer susceptibility. We searched PubMed, Embase, China...

The aim of the present study was to investigate the dynamic changes of five neurotransmitters and their associated enzymes in the rat plasma and brain tissues following the co-administration of β-asarone and levodopa (L-dopa). The rats were divided into...

The brain-derived neurotrophic factor (BDNF) val66met polymorphism differentially affects performance on subscales of the Wechsler Memory Scale - Third Edition (WMS-III).

Frontiers in psychology

PMID: 26347681
Front Psychol. 2015 Aug 17;6:1212. doi: 10.3389/fpsyg.2015.01212. eCollection 2015.

Single nucleotide polymorphisms in the brain-derived neurotrophic factor (BDNF) gene and the catechol-O-methyltransferase (COMT) gene influence brain structure and function, as well as cognitive abilities. They are most influential in the hippocampus and prefrontal cortex (PFC), respectively. Recall and...

Hydroxylation and sulfation of sex steroid hormones in inflammatory liver.

Journal of biomedical research

Lee SR, Lee SY, Kim SY, Ryu SY, Park BK, Hong EJ.
PMID: 28866654
J Biomed Res. 2017 Sep 26;31(5):437-444. doi: 10.7555/JBR.31.20170031.

Sex steroids, also known as gonadal steroids, are oxidized with hydroxylation by cytochrome P450, glucuronidation by UDP-glucuronosyltransferase, sulfation by sulfotransferase, andO-methylation by catechol O-methyltransferase. Thus, it is important to determine the process by which inflammation influences metabolism of gonadal...

Zh Nevrol Psikhiatr Im S S Korsakova. 2015;115(4):51-58. doi: 10.17116/jnevro20151154251-58.

AIM: A quantitative assessment of the impact of genetic factors (density of family history of alcohol dependence and dopamine system genes polymorphisms) on the average time to relapse (ATR) after alcohol dependence treatment (duration of therapeutic remission from alcohol...

Influence of Equatorial CH⋅⋅⋅O Interactions on Secondary Kinetic Isotope Effects for Methyl Transfer.

Angewandte Chemie (International ed. in English)

Wilson PB, Williams IH.
PMID: 26823274
Angew Chem Int Ed Engl. 2016 Feb 24;55(9):3192-5. doi: 10.1002/anie.201511708. Epub 2016 Jan 28.

DFT calculations for methyl cation complexed within a constrained cage of water molecules permit the controlled manipulation of the "axial" donor/acceptor distance and the "equatorial" distance to hydrogen-bond acceptors. The kinetic isotope effect k(CH3)/k(CT3) for methyl transfer within a...

Mercury promotes catecholamines which potentiate mercurial autoimmunity and vasodilation: implications for inositol 1,4,5-triphosphate 3-kinase C susceptibility in kawasaki syndrome.

Korean circulation journal

Yeter D, Deth R, Kuo HC.
PMID: 24174958
Korean Circ J. 2013 Sep;43(9):581-91. doi: 10.4070/kcj.2013.43.9.581.

Previously, we reviewed biological evidence that mercury could induce autoimmunity and coronary arterial wall relaxation as observed in Kawasaki syndrome (KS) through its effects on calcium signaling, and that inositol 1,4,5-triphosphate 3-kinase C (ITPKC) susceptibility in KS would predispose...

Lack of association between COMT gene and deficit/nondeficit schizophrenia.

Behavioral and brain functions : BBF

Wonodi I, Mitchell BD, Stine OC, Hong LE, Elliott A, Kirkpatrick B, Carpenter WT, Thaker GK, Buchanan RW.
PMID: 17173666
Behav Brain Funct. 2006 Dec 15;2:42. doi: 10.1186/1744-9081-2-42.

BACKGROUND: The dopamine dysregulation hypothesis of schizophrenia posits that positive, negative and cognitive symptoms correlate with cortical/subcortical imbalances in dopaminergic transmission. A functional polymorphism (Val158Met) in the catechol-O-methyltransferase (COMT) gene is implicated in the pathophysiology of schizophrenia by its...

Genetic contributions to age-related decline in executive function: a 10-year longitudinal study of COMT and BDNF polymorphisms.

Frontiers in human neuroscience

Front Hum Neurosci. 2008 Sep 23;2:11. doi: 10.3389/neuro.09.011.2008. eCollection 2008.

Genetic variability in the dopaminergic and neurotrophic systems could contribute to age-related impairments in executive control and memory function. In this study we examined whether genetic polymorphisms for catechol-O-methyltransferase (COMT) and brain-derived neurotrophic factor (BDNF) were related to the...

COMT Val158Met Polymorphism Modulates Cognitive Effects of Dietary Intervention.

Frontiers in aging neuroscience

Witte AV, Jansen S, Schirmacher A, Young P, Flöel A.
PMID: 21119769
Front Aging Neurosci. 2010 Nov 05;2:146. doi: 10.3389/fnagi.2010.00146. eCollection 2010.

A common single nucleotide polymorphism (SNP) in the gene encoding catechol-O-methyltransferase (COMT), Val158Met, is thought to influence cognitive performance due to differences in prefrontal dopaminergic neurotransmission. Previous studies lend support for the hypothesis that the "at risk" genotype comprising...
