Catechol-O-methyl transferase and schizophrenia.
Catechol-O-methyl transferase (COMT) is an enzyme involved in the degradation of dopamine. The most commonly examined polymorphism within the COMT gene is Val108/158Met polymorphism, which results in three to fourfold difference in COMT enzyme activity. It is particularely important in prefrontal cortex, since COMT activity is the most important regulator of the prefrontal dopamine function. Gi...
متن کاملMethionine sulfoxide reductase regulates brain catechol-O-methyl transferase activity.
Catechol-O-methyl transferase (COMT) plays a key role in the degradation of brain dopamine (DA). Specifically, low COMT activity results in higher DA levels in the prefrontal cortex (PFC), thereby reducing the vulnerability for attentional and cognitive deficits in both psychotic and healthy individuals. COMT activity is markedly reduced by a non-synonymous single-nucleotide polymorphism (SNP) ...
متن کاملassociation of catechol-o-methyl transferase gene polymorphism with prostate cancer and benign prostatic hyperplasia
background : a single nucleotide variation within atechol-o-methyl transferase (comt) gene may alter the comt enzyme activity level. polymorphism of val158met in the comt gene has been related to malignancy. in this regard, a study was carried out to find a possible association between the comt gene polymorphism in patients with sporadic prostate cancer (pca) and benign prostatic hyperplasia (...
متن کاملMembrane-Bound Catechol-O-Methyl Transferase in Cortical Neurons and Glial Cells is Intracellularly Oriented
Catechol-O-methyl transferase (COMT) is involved in the inactivation of dopamine in brain regions in which the dopamine transporter (DAT1) is sparsely expressed. The membrane-bound isoform of COMT (MB-COMT) is the predominantly expressed form in the mammalian central nervous system (CNS). It has been a matter of debate whether in neural cells of the CNS the enzymatic domain of MB-COMT is orient...
متن کاملCatechol-o-methyl Transferase and Monoamine Oxidase Activity in the Ocular Tissues of Albino Rabbits.
The distribution of catechol-O-methyl transferase and monoamine oxidase activity in the ocular tissues of albino rabbits has been determined with a radioactive tracer assay. The distribution of the former varied in the different tissues within a restricted range whereas the distribution of monoamine oxidase activity exhibited larger variations. Sympathetic denervation did not appear to affect c...
