The molecule influences the mammal orientation
It is reported ' Reporter Xu QiMin) The ancient addiction with dragon's male genital, breaks the feeling carried today. Why can he fall in love with him, but not she? The scientist has opened one mao of the answer to a riddle through gene studies. Dawn, Nature has been issued online the university students in Beijing have ordered scientific institute's professor, Beijing reputable researcher of research institute of life sciences to forgive the latest research of the firm seminar: On mammalian sex orientation, neurotransmission five the intersection of hydroxy and the intersection of color and amine possess important the intersection of words and right.

In the mammal, there is behavior that same sex of certain proportion seeks a spouse, a pair of sex seeks a spouse. If this kind of human behaviors mix the influence of the social cultural factor, why can other mammals be like this too if so? Unknown secrets are hidden in the origin of the life is it possible that - -In the gene?

This time, forgiving the firm seminar finds an interesting and key role - -Five hydroxy color amine. Five hydroxy color amine in the male little mouse brain plays a very important role: Have it, male little mouse can pursue " the the intersection of mouse and younger sister " ,Launch the fierce one to the opposite sex " The love offensive " ; Leave it, male little mouse seek a spouse the taste right away, the male and female are taken in concurrently.

In fact, scientist to 5 hydroxy color amine would have what's frequently heard can be repeated in detail - -It is also called serum plainly, it relates to human a series of behavior problem, relates to personality and affective disorder at the same time; But the impact on sex orientation, this is the first time found. In fact, the sex orientation is very important step of this important social behavior of seeking a spouse: The animal is impossible to select the spouse's dowry, family, but must choose the other side to be a female or hero. Such important social behavior, though everybody is accustomed to, the mankind knows little about its biological mechanism. In molecule and cell level, understand more scarcely.

Forgive the research of the firm seminar, it is to explain at the molecule level the mankind understands mammalian sex choice mechanism. Forgive firm and colleague make a large number of experiment, for example strike except that the intersection of male and little mouse of gene, because lack five hydroxy color amine in the body, demonstrate same sex seeking a spouse, behavior of seeking a spouse of a pair of sex of higher proportion, and after injecting five hydroxy color amine, have resumed the behavior that the opposite sex seeks a spouse.

Forgive firm to own scientific result of study these time but avoid all medias' interviewing, perhaps because the research contents are very easy the homosexual phenomenon in associating it with the human society. But his thesis write finally: " one question that can't avoid, five hydroxy the intersection of color and amine in (little mouse) The function played on the sex orientation is applicable too on one's body in the others mammal? Find in the human test of nuclear magnetic resonance imaging, it is not the same to have a partiality for the opposite sex and response to five hydroxy color amine of man of the partiality same sex. " However, in this research, scientists have not confirmed the gene correlated to it yet, his thesis says that hopes " this research can initiate more scientists' interest, participate in the research of neurotransmission and mammalian social behavior together.
