A U.S. study challenges the view that people with some genotypes are at greater risk for depression, anxiety and abuse of drugs and alcohol, researchers said. The researchers studied infant monkeys from four different rearing conditions to examine how social context and different forms of early adversity interact with genotype to influence behavior. Animals reared in small social groups were more likely to be aggressive and anxious, particularly among those with a low activity MAOA genotype....

A growing body of basic animal research and studies of abused and neglected children provide a strong basis of support for the hypothesis that individuals with particular genotypes are at greater risk for depression, anxiety disorders, and problems with the abuse of alcohol and other substances. These gene-by-environment interactions are so powerful that some might assume that these genotypes identify people who are predestined to negative life outcomes.However, a new study in the May 1st...

When alcohol mixes with a certain highly active gene, the outcome may be aggression and violence. It is widely known alcohol consumption and violence are related. In addition, crime statistics show most impulsive homicides involve adolescents and middle-aged groups. Researchers in Finland set out to find a link between these elements and violence. Monoamine oxidase A (MAOA) is a gene that breaks down monoamines like serotonin, noradrenaline and dopamine. Some variations of the gene can cause...

HAMBURG, Germany, Oct. 27, 2008 (GLOBE NEWSWIRE) -- Evotec AG (Nasdaq:EVTC) (Frankfurt:EVT) announced today encouraging results of a Phase I safety study investigating the potential interaction of EVT 302, a reversible and highly selective inhibitor of monoamine oxidase B (MAO-B) in development for smoking cessation, with tyramine. The study was undertaken to determine potential safety advantages of EVT 302 versus non-selective MAO inhibitors and less selective MAO-B inhibitors already on the...

Researchers at the University of North Carolina reported Monday that genes may play a role in young men who grow up in tough neighborhoods or with disadvantaged families and later become violent criminals. The scientists have identified three genes they believe play a role. One, called MAOA, played a particularly strong role, and had been shown in previous research to affect antisocial behavior. The researchers called the gene "disturbingly common". Sociology professor Guang Guo, who led the...

By Charnicia Huggins NEW YORK (Reuters Health) - Why are some men confrontational or break objects in fits of anger, while others appear to be more in control under similar circumstances? New study findings suggest the answer may involve genetic differences in combination with the men's early environment. A variation in a gene involved in the activity of the brain chemical serotonin, which is known to play an important role in regulating emotions and impulses, may cause some men to...

RESTON, Va. -- Smoking appears to reduce a key enzyme in the lungs, possibly contributing to some of smoking's deleterious health effects, according to a study published in the September issue of the Journal of Nuclear Medicine. The study, which used a radiotracer to track the enzyme, also shows that smokers had a lower concentration of the tracer in the bloodstream than nonsmokers did, leading to speculation that smokers and nonsmokers may respond differently to a variety of substances...

A class of drugs known as MAO-B inhibitors may be effective in improving motor symptoms in people with early Parkinson's disease and may delay the need for treatment with other drugs, according to a new systematic review of current evidence. However, contrary to results from other studies, the researchers found that MAO-B (monoamine oxidase B) inhibitors do not appear to slow the disease's progression. " The benefits of MAO-B inhibitors are small but may be worthwhile in some patients," says...
