Abstract
Lower platelet monoamine oxidase (MAO) activity has been associated with problem behaviors, including criminal behavior, but not all studies agree. We have examined platelet MAO activity and antisocial behavior involving police contact in a longitudinal birth cohort study. The sample included both birth cohorts (original n = 1238) of the Estonian Children Personality Behavior and Health Study. Platelet MAO activity was measured at ages 15, 18 and 25 radioenzymatically with β-phenylethylamine as the substrate. Police contacts were self-reported in an interview and drug use in a questionnaire filled in during a laboratory visit. In cross-sectional analyses, males with the record of antisocial behavior had lower platelet MAO activity. In longitudinal mixed-effect regression models, this association was found to be independent of smoking. Furthermore, including smoking in the model revealed lower platelet MAO activity also in females with past antisocial behaviour. A further exploratory regression analysis with antisocial behavior at two levels of frequency and consideration of self-reported use of illicit drugs either in a single occasion or repeatedly demonstrated some "dose-dependency" in the relationship of antisocial behavior and platelet MAO activity. Platelet MAO activity was lower in male but not female subjects with basic education level as compared to secondary and higher education, but it was not related to non-verbal intelligence. Neither was platelet MAO activity associated with socio- economic status. In conclusion, antisocial behavior as occurring in general population is associated with low platelet MAO activity that probably reflects low capacity of the serotonergic system.

Abstract
It has been proposed that an MAOA abnormality may be an important factor in the development of major depressive disorder (MDD). Various polymorphisms of the MAOA gene have been investigated for possible associations with mood disorders, but results have been inconsistent. The goal of the present study was to investigate whether polymorphisms of the MAOA gene are associated with MDD or alternatively with different clinical subgroups of MDD. A total of 590 Han Chinese subjects in Taiwan (312 controls and 278 MDD patients) were recruited. Among the males, there were no associations with MAOA polymorphisms. Among the females, an association was found between MAOA polymorphisms and severe MDD (P=0.041 for uVNTR and 0.017 for EcoRV (rs1137070), respectively). However, in analyses of haplotype frequencies and multiple logistic regression, MAOA polymorphisms were not associated with either MDD or its subgroups. The results suggest that MAOA polymorphisms do not play a major role in the pathogenesis of MDD or its subgroups. However, a potential role for a minor association with some specific subgroups and with different ethnic samples needs to be explored further.

Abstract
Most of the candidate gene studies in bipolar disorder have focused on the major neurotransmitter systems that are influenced by drugs used in the treatment of this disorder. The monoamine oxidase A (MAOA) and the tryptophan hydroxylase (TPH1, TPH2) genes are two of the candidates that have been tested in a series of association studies using unrelated or family-based controls. This review summarizes the existing association studies regarding these genes. Most of these studies were based on the unrelated case-control design with samples of 50 to 600 subjects. Regarding MAOA, three meta-analyses with partially overlapping samples supported a modest effect of this gene in bipolar disorder in female Caucasians. However, as several studies could not replicate these findings, more work is necessary to demonstrate unequivocally the involvement of MAOA in bipolar disorder and establish the biological mechanism underlying the genetic association. With respect to TPH1 and TPH2, the majority of studies did not provide evidence for an association between these genes and bipolar disorder. The genes are more likely to be related to suicidal behavior than to bipolar disorder.

Abstract
1. The effect of gender, smoking and pubertal development on platelet monoamine oxidase (MAO) activity was described in a randomly selected, large sample of 9- and 15-years old healthy children. 2. Platelet MAO activity was measured in 1129 children by a radioenzymatic method with beta-phenylethylamine as the substrate. Smoking habits were reported in an anonymous questionnaire. Pubertal status was assessed visually using Tanner's stages. 3. Boys, younger children and smokers had significantly lower platelet MAO activity than girls, older children and non-smokers, respectively. Girls in Tanner's stage V for breast and pubic hair development had significantly lower MAO than girls in stage IV. 4. Differences in gender, age, pubertal status and smoking habits must be taken into account if the relationship between platelet MAO activity, personality and psychiatric disorders is studied in children.

Abstract
Tobacco smoke exposure has been shown to inhibit brain and platelet MAO B in animals and in humans. Though the mechanism(s) responsible for MAO B inhibition are not known, studies in rodents have shown that nicotine administration does not inhibit brain MAO B. In this study we investigated whether brain MAO B is also unaffected by nicotine in the living primate. Brain MAO B was measured with positron emission tomography (PET) and deuterium substituted [11C]L-deprenyl ([11C]L-deprenyl-D2) in three baboons at baseline and 5 minutes after the injection of (-)-nicotine (0.3 mg administered intravenously). A three-compartment model was used to calculate the plasma to brain transfer constant K1 which is related to blood flow, and lambda k3, which is a function of the concentration of catalytically active MAO B molecules. Nicotine administration did not produce significant changes in either of these parameters. This study in living baboons confirms previous studies in rodents and solidifies the notion that other mechanisms for MAO B inhibition observed in smokers need to be considered.

Abstract
There have been several conflicting reports of association of monoamine oxidase (MAO) A gene polymorphisms and bipolar affective disorder. In order to determine the possible role of the MAO region in susceptibility to affective disorders in an independent sample, we have genotyped 83 probands of bipolar affective disorder families, 56 sets of parents of bipolar probands, and 84 normal controls for intronic simple sequence repeat polymorphisms of the MAO-A and MAO-B genes. For MAO-A there were no significant differences in allele frequencies between bipolar and normal control groups for both genders. However, for MAO-B there were significant differences between groups for both genders. In contrast, allele-wise haplotype relative risk analysis for the 56 bipolar proband-parent trios found no significant differences between transmitted and non-transmitted allele frequencies for MAO-A or B. These data do not support the association of MAO-A or B with bipolar affective disorder but do demonstrate that undetected population stratification can be an important source of bias in case-control studies.

Abstract
Platelet monoamine oxidase activity (MAO) and clinical symptoms were examined in 116 individuals, 32 acute depressed patients and 84 healthy controls. The enzyme activity was lower in depressed women than controls. MAO activity correlated positively with rated clinical state in depressed women but not in depressed men. Patients were reexamined after 10 years and categorized into affective psychosis (endogenous) or neurotic depression (International Statistical Classification of Diseases, Injuries and Causes of Death, 1987; ICD-9). Neurotic depressed occurred frequently in the low activity group. Endogenously depressed showed positive correlation between MAO activity and rated clinical state. The association between platelet MAO activity and clinical state is discussed.

Abstract
We present evidence of a genetic association between bipolar disorder and alleles at 3 monoamine oxidase A (MAOA) markers, but not with alleles of a monoamine oxidase B (MAOB) polymorphism. The 3 MAOA markers, including one associated with low MAOA activity, show strong allelic association with each other but surprisingly not with MAOB. Our results are significant only for females, though the number of males in our sample is too small to draw any definite conclusions. Our data is consistent with recent reports of reduced MAOA activity in patients with abnormal behavioral phenotypes. The strength of the association is weak, but significant, which suggests that alleles at the MAOA locus contribute to susceptibility to bipolar disorder rather than being a major determinant.

Abstract
Platelet monoamine oxidase activity (MAO), melatonin and cortisol post-dexamethasone suppression test (DST) were examined in 28 patients with major affective disorder and in 20 controls. MAO activity was lower and cortisol post-dexamethasone was higher in depressed patients. Platelet MAO activity and cortisol in depressed and controls yielded high sensitivity (90%) and specificity (89%). The patients were re-examined after 10 years and categorized into affective psychosis or neurotic depression (ICD-9). Multidimensional analysis identified one subgroup coinciding in 92% with affective psychosis and another subgroup coinciding in 87% with neurotic depression. Combination of MAO, melatonin and post-DST cortisol may be useful in the diagnosis of subgroups of depressed patients and in choice of therapy.

Abstract
Monoamine oxidases, type A and type B, are principal enzymes for the degradation of biogenic amines, including catecholamines and serotonin. These isozymes have been implicated in neuropsychiatric disorders. Previously, cDNA clones for both MAO-A and MAO-B have been sequenced and the genes encoding them have been localized to human chromosome Xp11.23-Xp11.4. In this work, we isolated human genomic clones spanning almost all the MAOA gene from cosmid and phage libraries using a cDNA probe for MAO-A. Restriction mapping and sequencing show that the human MAOA gene extends over 70 kb and is composed of 15 exons. The exon structure of human MAOA is similar to that described by others for human MAOB. Exon 12 (bearing the codon for cysteine, which carries the covalently bound FAD cofactor) and exon 13 are highly conserved between human MAOA and MAOB genes (92% at the amino acid level). Earlier work revealed two species of MAO-A mRNA, 2.1 kb and 4.5-5.5 kb. We now report on further cDNA isolation and sequencing, which demonstrates that the longer message has an extension of 2.2 kb in the 3' noncoding region. This extended region is contained entirely within exon 15. The two messages therefore appear to be generated by the use of two alternative polyadenylation sites. Results from the present work should facilitate the mutational analysis of functional domains of MAO-A and MAO-B. Knowledge of the gene structure will also help in evaluating the role of genetic variations in MAO-A in human disease through the use of genomic DNA, which is more accessible than the RNA, as a template for PCR-amplification and sequencing.

Abstract
A significant negative correlation between platelet monoamine oxidase (MAO) activity, a stable peripheral enzyme measure under genetic control, and sensation seeking, as measured using the Zuckerman Sensation Seeking Scale (SSS), has been reported for male subjects in several studies. As tobacco smoking has been related to both these measures, in the present study correlations were calculated among smoking and non-smoking male university students. Platelet MAO activity was negatively correlated with the Disinhibition and Total scales of the SSS. These correlations were not significantly different in smokers and non-smokers. The results are discussed in terms of recent evidence of reduced platelet MAO activity in psychiatric patients.
