Short genes lead to more severe depression

Short genes lead to more severe depressionThe researchers found that the likelihood of depression in humans depends on the type of specific genes, which he bears. The researchers watched for 30 years for the group in 847 people born in 1972-1973 in New Zealand. Scientists have tried to understand why some people are easier to cope with stressful situations, such as divorce or dismissal from work, while others fall into a deep depression. Suspicions researchers were associated with the gene, known under the code 5-NTT, which controls the production of serotina in the human body. It is believed that the level of serotina that participates in the transmission of nerve impulses between brain cells, affects our mood. Every man carries within him a couple of 5-NTT. However, they are of two types - short and long. Scientists have found that people with a pair of long genes were 2.5 times more likely to escape from life's troubles, without falling into depression than those who got the short version of the gene. From the study group were allocated to those who have experienced serious stressful situation between 21 and 26 years of his life, according to BBC. It turned out that of the 265 people who wore a pair of short genes, 43% experienced a deep depression due to stress. This figure for people with long type 5-NTT (only they were 147) was 17%. According to the Professor of the London Institute of psychiatry at kings College Teri of Moffit participating in the study, this does not mean that the gene 5-NTT causes depression, it only affects the resistance of the organism to the effects of stress. "So far, we started to treat depression only when it got dangerous. Wouldn't it be great if doctors will be able preventive treatment of these States," said Moffit. According to the Professor, this study opens new perspectives for the use of the possibilities of genetics in medicine. The results were published in the journal"science". News.
