英国科学家发现人体生物钟“齿轮”  发帖心情 Post By:2008/8/5 14:54:29

    (伦敦讯)据英国《金融时报》报道,对生理节律的研究,发现了人体生物钟上一个不曾预料到的新分子齿轮。一个名为c-AMP的小分子在视交叉上核(suprachiasmatic nuclei, SCN)中扮演了关键的信令角色。人体生物钟就位于大脑中的视交叉上核。

  这项发现于5月16日发表在《科学》杂志上,是由位于剑桥的英国医学研究委员会分子生物学实验室的迈克尔·黑斯廷斯及其同事做出的。

  医学研究委员会相信,对于因航空旅行、倒班或疾病打乱了睡眠规律的人,控制c-AMP生物路径的药物能够重新设置他们的生物钟。该委员会已就此项技术提出专利申请。

  黑斯廷斯表示:“生理节律混乱日益成为慢性疾病的重要成因。如果我们能找到控制生物钟的方法,也许就能知道在生物钟紊乱时如何进行调节。”
