2. Zebrafish MAO (zMAO) exhibits functional properties similar to human hMAO A as well as exhibits its own unique behavior.

3. expression, purification & characterization of zebrafish monoamine oxidase (zMAO) using Pichia pastoris expression system is described; zMAO possesses little differential sensitivity to acetylenic inhibitors than exhibited by either human MAO A & MAO B

4. this study confirm the presence of functionally active MAO in zebrafish brain and other tissues and characterize the neural systems that express MAO and areas of intense activity in the brain.

1. Our observations provide new information on the genotype-phenotype relations of MAOA/B and EFHC2 genes involved in the contiguous deletions of Norrie disease.Based on the case of our observation, contiguous deletion with only one of the MAO genes (MAOB) may not cause psychomotor disability, and deletion of EFHC2may not contribute to epilepsy.

2. the mean methylation values of the CpG sites studied in the MAOA gene were related to smoking behavior in women.

9. This study suggests that MAOB increases ASD risk in males, possibly through its sex-specific regulatory effect on 5-HT metabolism and behavior.

10. These findings suggest an association of platelet MAO-B activity, but a lack of association of MAOB rs1799836 and MAOA-uVNTR, with selected psychotic symptoms in ethnically homogenous veterans with PTSD.

11. No significant association was found between severe agitation and MAOA uVNTR or MAOB rs1799836 polymorphism, revealing that these individual polymorphisms in MAO genes are not related to severe agitation in subjects with schizophrenia and conduct disorder. Higher platelet MAO-B activity was found in subjects with severe agitation vs. non-agitated subjects. Platelet MAO-B activity was not associated with MAOB rs1799836

12. we performed a meta-analysis in the Chinese population to provide comprehensive data on the association between the MAOB polymorphism and Parkinson's disease. Overall, no significant association was found between the MAOB A644G polymorphism and Parkinson's disease risk in the Chinese population.

13. inhibition of MAO-B using selegiline reversed the cigarette smoke-induced oxidative stress and inflammation in bronchial epithelial cells.

14. Monoamine oxidase B levels are highly expressed in gliomas.

15. The results of this meta-analysis suggest that people in the Asian population with the MAOB intron 13 A allele have an increased risk of Parkinson disease, especially when combined with the COMT LL genotype.

16. Huntington disease neural cells exhibit increased Monoamine oxidase-A and Monoamine oxidases-B expression and activity

17. Report isolation of MOA-B inhibitors from Vernonia cinerea.

18. These findings demonstrate that regulation of monoamine levels by Mao activity in beta cells is pivotal for physiological insulin secretion and that loss of MaoB expression may contribute to the beta cell dysfunction in type 2 diabetes.

19. findings indicate that the low activity of monoamine oxidase gene polymorphisms has a protective effect on smoking cessation and smoking frequency.

20. protein environment of MAO-A enhances the polar nucleophilic character of the mechanism compared to that of MAO-B

1. cloning and characterization of monoamine oxidase A and B genes in pig

Mouse (Murine) Monoamine Oxidase B (MAOB) Interaktionspartner

1. findings thus support that AEP-mediated cleavage of alpha-Syn at N103 is required for the association and activation of MAO-B, mediating Parkinson's disease pathogenesis.

2. Hydralazine (Hdz) abrogated the degradation of tele-methylhistamine (tMH) catalyzed by monoamine oxidase B (MAO-B) in vitro.

3. Huntington disease neural cells exhibit increased Monoamine oxidase-A and Monoamine oxidases-B expression and activity

4. Activity of monoamine oxidase B in the striatum is reduced during the presymptomatic stage, but returns to the control level during the symptomatic stage of Parkinsonism in mice.

5. These findings demonstrate that regulation of monoamine levels by Mao activity in beta cells is pivotal for physiological insulin secretion and that loss of MaoB expression may contribute to the beta cell dysfunction in type 2 diabetes.

6. Monoamine oxidase B deficiency (along with monoamine oxidase A) resulted in an array of abnormalities similar to autism-spectrum disorder.

7. chronic elevations of monoamines, because of the absence of MAO A and MAO B, cause functional alterations that are accompanied with changes in the cellular mechanisms underlying learning and memory.

8. MAO-B is involved in the acute neurotoxicity of MPTP in embryonic and newborn mice

9. Data suggest that both IR1 (imidazoline receptor 1) and IR2/Maob play roles in acquisition of behavioral responses in alcoholism; activation of IR1 and IR2/Maob may serve as molecular targets in prevention (and possibly treatment) of alcoholism.

11. MAO-B seems to exert a critical role in the development of postoperative and neuropathic pain

12. The temporal sequence of events following MAO-B elevation initially involves increased oxidative stress followed by mitochondrial complex I inhibition and finally neurodegeneration.

13. Data indicate that the activity of MAOB could modulate the regular and amphetamine-perturbed expression of GAD(67) and pCREB, and suggest interactions among the MAOB activity, GABA content of OlfB, and olfaction.

14. The findings of this study revealed novel roles for MAO-b and serotonin in the regulation of intermediate progenitor cells proliferation in the developing brain.

15. a monoamine-oxidase epigenetic regulation is involved in effects of smoking

16. these results suggest that MAO B deficiency may lead to behavioral disinhibition and decreased anxiety-like responses partially through regional increases of Phenylethylamine levels.

17. Observed chase/escape and anxiety-like behavior in the MAO A/B KO mice, different from MAO A or B single KO mice, suggest that varying monoamine levels result in both a unique biochemical and behavioral phenotype.

18. Moreover, MAOB is region-dependently involved in responses of the brain to Amph and baclofen, supporting interactions between GABA and monoamines.

19. Elevated astrocytic MAO-B mimicking age related increase resulted in specific, selective and progressive loss of dopaminergic neurons in the substantia nigra, accompanied by decreases in mt complex I activity and increased mt oxidative stress.

20. data strongly suggest that, although MAO-B is highly expressed in focal freeze brain injury, its activity does not contribute to the cellular damage or play any role in regulating astrocytic reactivity
