Methionine 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 کاملCatechol-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 کاملDocking Based De novo Design of Few Tolcapone Derivatives as Catechol-o- Methyl Transferase (Comt) Inhibitors
Catechol-O-methyl tranferase (COMT; E.C.2.1.1.6) is widely distributed enzyme in nature that plays an essential role in the metabolism of catechol neurotransmitters and catechol linked foreign entities. As L-DOPA, a key medicine in Parkinsonism is being catabolised by COMT, this justified the interest in developing improved COMT inhibitors as significant adjunct to L-DOPA therapy. Although tolc...
متن کاملEffects of β-Adrenoceptor and Catechol-O-Methyl-Transferase (COMT) Polymorphism on Postoperative Outcome in Cardiac Surgery Patients
BACKGROUND There is a long-standing debate about the role of beta-adrenoceptor polymorphisms in the cardiovascular system. We wanted to elucidate whether β1-adrenoceptor-polymorphisms affects the postoperative catecholamine consumption and the length of intermediate care unit stay in patients undergoing cardiac surgery, and whether this might be enhanced or attenuated by catechol-O-methyl-trans...
متن کاملAssociation Between MTHFR Genetic Variants and Multiple Sclerosis in a Southern Iranian Population
Multiple sclerosis (MS) is a demyelinating neuro- inflammatory autoimmune disease of the central nervous system. Genetic predisposition has long been suspected in the etiology of this disease. The association between MTHFR polymorphisms and MS has been ivestigated in different ethnic groups. We investigated the association between MTHFR C677T and A1298C missense variants and MS in 180 patients ...
