Abstract
Nicotine, the main compound in cigarettes, leads to smoking addiction. Nicotine acts on the limbic dopamine reward loop in the midbrain by binding to nicotinic acetylcholine receptors, promoting the release of dopamine, and resulting in a rewarding effect or satisfaction. This satisfaction is essential for continued and compulsive tobacco use, and therefore dopamine plays a crucial role in nicotine dependence. Numerous studies have identified genetic polymorphisms of dopaminergic pathways which may influence susceptibility to nicotine addiction. Dopamine levels are greatly influenced by synthesis, storage, release, degradation, and reuptake-related genes, including genes encoding tyrosine hydroxylase, dopamine decarboxylase, dopamine transporter, dopamine receptor, dopamine 3-hydroxylase, catechol-O-methyltransferase, and monoamine oxidase. In this paper, we review research progress on the effects of polymorphisms in the above genes on downstream smoking behavior and nicotine dependence, to offer a theoretical basis for the elucidation of the genetic mechanism underlying nicotine dependence and future personalized treatment for smoking cessation.

Association of COMT rs4680 and MAO-B rs1799836 polymorphisms with levodopa-induced dyskinesia in Parkinson's disease-a meta-analysis. Neurol Sci 2021; 42:4085-4094. [PMID: 34346015 DOI: 10.1007/s10072-021-05509-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Accepted: 07/18/2021] [Indexed: 01/20/2023]
Abstract
BACKGROUND AND PURPOSE Polymorphisms of the catechol-O-methyl transferase (COMT) or monoamine oxidase B (MAO-B) genes may affect the occurrence of dyskinesia in Parkinson's disease (PD) patients. However, the findings are inconsistent. Thus, we performed a meta-analysis to assess whether COMT and MAO-B genetic variants are associated with an increased incidence of levodopa-induced dyskinesia (LID) in PD patients. METHODS A literature search of PubMed, Embase, and Cochrane Library was conducted to identify relevant studies published up to January 2021. The strength of the association between the polymorphisms and LID susceptibility was estimated by odds ratio (OR) and associated 95% confidence interval (CI). The pooled ORs were assessed in different genetic models. RESULTS Ten studies involving 2385 PD patients were included in the meta-analysis. Analysis of pooled ORs and 95% CIs suggested that the AA genotype of COMT(rs4680) was associated with LID (OR = 1.39, 95%CI: 1.02-1.89, P = 0.039) in the recessive model, and this correlation was more obvious in Brazilian samples in the analysis stratified by ethnicity. For the AG genotype of MAO-B(rs1799836), the pooled OR was 1.66 (95% CI: 1.04-2.65, P = 0.03) in patients with LID versus those without LID in the heterozygote model. CONCLUSIONS Our meta-analysis implicates the AA genotype of the COMT rs4680 polymorphism as potentially increasing the risk of LID in a recessive genetic model for PD patients. Furthermore, the AG genotype of the MAO-B rs1799836 polymorphism may influence the prevalence of LID in PD patients in the heterozygote model. However, further well-designed studies with larger PD patient cohorts are required to validate these results after adjusting for confounding factors.

Abstract
The most commonly used Parkinson's disease (PD) treatment is the replacement of dopamine by its levodopa precursor (l-dopa). Monoamine oxidase-B (MAO-B) and catechol-o-methyl transferase (COMT) are enzymes involved in the metabolism and regulation of dopamine availability. In our study we investigated the possible relation among selected single-nucleotide polymorphisms (SNPs) in the MAO-B (rs1799836) and COMT (rs4680) genes and the therapeutic response to levodopa (l-dopa). A total of 162 Brazilian patients from the Pro-Parkinson service of Clinics Hospital of Pernambuco diagnosed with sporadic PD and treated with levodopa were enrolled. PD patients were stratified into 2 groups according to the daily levodopa dose. MAO-B and COMT SNP genotyping was conducted by polymerase chain reaction-restriction fragment length polymorphism. After multivariate analysis, we observed a significant difference between PD groups for the following variables: sex (P = .02), longer duration of disease (P = .02), longer levodopa therapy duration (P = .01), younger onset of PD (P = .01), and use of COMT inhibitor (P = .02). We observed that patients carrying MAO-B (rs1799836) A and AA genotypes and COMT (rs4680) LL genotype suffered more frequently from levodopa-induced-dyskinesia. In addition, we found an increased risk of 2.84-fold for male individuals carrying the MAO-B G allele to be treated with higher doses of levodopa (P = .04). We concluded that before beginning PD pharmacological treatment, it is important to consider the genetic variants of the MAO-B and COMT genes and the sex, reinforcing the evidence that sexual dimorphism in the genes related to dopamine metabolism might affect PD treatment.

Abstract
Monoamine oxidase B (MAO-B) plays an important role in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues. Increased levels of MAO-B mRNA and enzymatic activity have been reported in platelets from patients with Parkinson's and Alzheimer's diseases, however the triggers of enhanced mRNA levels are unknown. Our results demonstrate for the first time that G/A dimorphism in intron 13 sequence creates splicing enhancer thus stimulating intron 13 removal efficiency. The increased MAO-B protein levels might serve as a surrogate marker for - Parkinson disease.

Abstract
Attention deficit hyperactivity disorder (ADHD) is a common neuropsychiatric condition with strong genetic basis. Recent work in China indicated that ADHD may be linked to Xp1-2 in the Han Chinese population. The gene encoding monoamine oxidase B (MAOB), the main enzyme degrading dopamine in the human brain, is located in this region. The current study sequenced the exons and the 5' and 3' flanking regions of the MAOB gene and found four common variants including 2276C>T and 2327C>T in exon 15, rs1799836 in intron 13 and rs1040399 in 3'-UTR. We assessed the association of these variants with ADHD in 548 trios collected from 468 males and 80 females probands. TDT analysis showed that alleles of each polymorphism were preferentially transmitted to probands (rs1799836, P = 3.28E-15; rs1040399, P = 1.87E-6; 2276T>C or 2327T>C, P = 2.20E-6) and haplotype-based TDT analyses also found distorted transmission. In conclusion, this study provides the strongest evidence for the involvement of MAOB gene in the etiology of ADHD to date, at least in Han Chinese population.

Abstract
The aim of the present study was to evaluate the contribution of MAOB, COMT, NAT2 and CYP2D6 gene polymorphisms to early onset Parkinson's disease (PD). The study enrolled 134 patients with Parkinson's disease (early onset-EOPD--67 patients, and late onset--LOPD--patients), and 66 healthy individuals. Polymerane chain reaction restriction fragment length polymorphism (PCR-RFLP) methods were used for genotyping. Univariate analysis revealed a significant two-fold higher EOPD risk among carriers of MAOB allele A or AA genotype. Multivariate analysis revealed that MAOB allele A was an independent factor predisposing to EOPD. It was shown that neither NAT2, CYP2D6 nor COMT genotype was associated with PD.

Abstract
Positron emission tomography (PET) using radiotracers with high molecular specificity is an important scientific tool in studies of monoamine oxidase (MAO), an important enzyme in the regulation of the neurotransmitters dopamine, norepinephrine, and serotonin as well as the dietary amine, tyramine. MAO occurs in two different subtypes, MAO A and MAO B, which have different substrate and inhibitor specificity and which are different gene products. The highly variable subtype distribution with different species makes human studies of special value. MAO A and B can be imaged in the human brain and certain peripheral organs using PET and carbon-11 (half-life 20.4 minutes) labeled mechanism-based irreversible inhibitors, clorgyline and L -deprenyl, respectively. In this article we introduce MAO and describe the development of these radiotracers and their translation from preclinical studies to the investigation of variables affecting MAO in the human brain and peripheral organs.

Abstract
Tobacco smoke inhibits monoamine oxidase-B (MAO-B) activity in vitro and in vivo, suggesting that MAO-B inhibition is a possible contributing factor to tobacco smoke addiction. Thus, MAO-B is a possible candidate gene for predisposition to smoking. The TaqIB polymorphism for the Dopamine D2 Receptor gene (DRD2) has been previously associated with smoking status, although with some contradictory results. We investigated whether genetic variants of MAO-B intron 13 and DRD2 TaqIB polymorphism could be associated with smoking status among control subjects. There was no association of the intron 13 polymorphism itself with smoking status in either men or women. Similarly, no association with smoking status was observed for the TaqIB polymorphism of DRD2 itself. However, among men, there was an interaction between MAO-B intron 13 polymorphism and the DRD2 TaqIB polymorphisms, in which subjects carrying MAO-B allele A and genotype B12 of DRD2 were 2.50 times (95% CI=1.05-5.95) more likely to be ever-smokers than the pool of men carrying all other genotype combinations. These results demonstrate that particular combinations of genotypes for MAO-B and DRD2 genes are associated with significantly higher risk for smoking behavior in men, but not in women.

Abstract
The activity of monoamine oxidase-B (MAO-B) enzyme has a high degree of heritability, although no common genetic polymorphisms are present in the MAO-B coding region. The only known polymorphisms in MAO-B gene are a C-1,114T in the 5' region, a variable number of GT repeats in intron 2, and a G/A change in intron 13. The genetically determined differences in MAO-B activity among subjects most likely derive from functional differences conferred by these three MAO-B genetic polymorphisms, or by polymorphisms in trans-acting factors that regulate MAO-B expression. In order to identify differences in transcriptional activity conferred by the MAO-B genetic variants, we cloned alternative alleles at the three polymorphic loci in -1,114, intron 2 and intron 13, and tested them in transfection-luciferase assays in HepG2 hepatoma and 1321N1 astrocytoma cells. The mutant -1,114 allele T had higher activity than allele C in both cell lines, when cloned in pGL3Enhancer. Significant differences in trascriptional activity by intron 2 GT repeat allele were also observed, and varied by cell type and reporter construct. Allele G of intron 13 had significantly higher activity than allele A in both cell lines. These results indicate transcriptional activity differences between MAO-B variant alleles that are naturally occurring in the population.
