COMT DNA methylation (show HELLS Antibodies) level is affected by the severity of the clinical symptoms of schizophrenia and might also be influenced by pharmacological treatment.
findings suggest that Val/Val homozygous individuals for catachol-O-methyltransferase (COMT) may be more flexible regarding self-attribution/body ownership and that biological factors may contribute to reduced awareness regarding the distinction between self and others.
Study provides evidence for an epistatic interaction between ZNF804A rs1344706 and COMT rs4680 on the grey matter volume of the left dorsolateral prefrontal cortex, which may improve our understanding on the biological mechanism underlying the genome-wide supported variant ZNF804 rs1344706 of schizophrenia on the prefrontal anatomy.
Logistic regressions with interaction terms (adjusted for sex and age) revealed that comt rs4680 interacted with total childhood adversity, emotional abuse and physical abuse in predicting panic disorder.
No significant difference was observed in the RNA levels of CYP1A1 (show CYP1A1 Antibodies) and SULT1A1 (show SULT1A1 Antibodies) between the two groups. The frequency of expression of the CYP17 (show CYP17A1 Antibodies) T/C variant tended to be higher and the A allele of COMT polymorphism together with down-regulation of its mRNA expression may be more frequent in Chinese women with idiopathic POI
Individuals carrying Val/Val of COMT seem to be more sensitive to the synergistic effect of environmental factors acting early in neurodevelopment.
childhood urbanicity and variation in dopamine genes COMT, DRD1 (show DRD1 Antibodies) and DRD2 (show DRD2 Antibodies) alters adult prefrontal function as measured by fMRI
the association between the COMT Val158Met and ZDHHC8 (show ZDHHC8 Antibodies) rs175174 single nucleotide polymorphism and the susceptibility to schizophrenia through a case-control study involving a population from the North Region of Brazil, was investigated.
Results revealed a sex-specific effect of COMT on corpus callosum (CC): in males only, Val homozygotes had significantly higher fractional anisotropy (FA) compared to Met-carriers. Volume-of-interest analysis showed a genotype by sex interaction on FA in genu and rostral midbody of CC, whereby Val males demonstrated higher FA than Met females.
No association between self-reported non-recovery or pain levels and COMT haplotypes in in a Northern European patients with acute whiplash injuries could be detected.
Miroestrol restored uterine COMT expression in beta-naphthoflavone-treated mice.
This study report that genetically driven reduction in COMT enzyme activity increased cortical thickness in the prefrontal cortex (PFC (show CFP Antibodies)) and postero-parieto-temporal cortex of male, but not female adult mice.
COMT expression in the hippocampus was significantly reduced by high E2 replacement, implying increased catecholamine levels in the hippocampus of high E2 mice.
COMT overexpressing mice display an increase in dopamine release capacity in the striatum, suggesting increased COMT activity may affect dopamine signaling by enhancing synaptic clearance in the cortex and changes in striatal presynaptic dopamine function
These data confirm at the level of mouse working memory and human working memory-associated physiology a genetic interaction between COMT and DTNBP1 (show DTNBP1 Antibodies).
The results of this study suggest that individual differences in COMT activity do not affect primary reinforcing effects of cocaine in mice.
Inhibition of COMT via serotonin binding contributes to pain hypersensitivity.
COMT knockout mice were more impulsive compared with wild-type littermates.
Data show that in male catechol-O-methyltransferase COMT(-/-)-mice, the total number of T-, and B-lymphocytes from spleen increased but the T-cell proliferative response decreased.
decreased COMT activity was associated with some changes in feeding microstructure in rats and mice
An analysis of polymorphisms of the COMT gene as a preliminary step in evaluating the role of the gene in behavior is reported.
Catechol-O-methyltransferase catalyzes the transfer of a methyl group from S-adenosylmethionine to catecholamines, including the neurotransmitters dopamine, epinephrine, and norepinephrine. This O-methylation results in one of the major degradative pathways of the catecholamine transmitters. In addition to its role in the metabolism of endogenous substances, COMT is important in the metabolism of catechol drugs used in the treatment of hypertension, asthma, and Parkinson disease. COMT is found in two forms in tissues, a soluble form (S-COMT) and a membrane-bound form (MB-COMT). The differences between S-COMT and MB-COMT reside within the N-termini. Several transcript variants are formed through the use of alternative translation initiation sites and promoters.
