2、各种鱼类间的系统进化关系。利用CLUSTALW多重序列比对,发现MSTN基因上的C端生物活性区在鱼类还是哺乳类或是鸟类,都具有很强的保守性,且在C端都具有一个保守的蛋白酶加工位点RXXR及9个CYS残基。同时在保守性强C端区域内仅有几处存在碱基的替换,其中在碱基数分别为36BP和19BP的两个高度保守片段上,36BP的氨基酸片段,除了大黄鱼有一处R替换G,鸟类和哺乳类有一处D替换A外,所有鱼类都是相同的。19BP的氨基酸片段,除了溪红点鮭有一处T替换A,大西洋鲑有一处I替换V外,从鱼类到哺乳类都是相同的。在CLUSTALW的基础上通过MEGA41软件以35种脊椎动物MSTN氨基酸序列构建的进化

3、树上分析得到,鲈形总目的鱼类(大黄鱼、花鲈、罗非鱼、石鼓鱼、美国红鱼和青鳉)之间相似性高达8899,同时鲈形总目鱼类与其它两种(鲱形总目和鲤形总目)之间的相似性分别有8290及7282,而鲱形总目与鲤形总目的鱼类之间相似性有7988。MSTN的研究将更有助于了解鱼类肌肉发育调控和进化机理。关键词鱼类;肌肉生长抑制素基因;同源性;进化分析ABSTRACTTHEGENEOFMYOSTATINISANEGATIVEREGULATOROFSKELETALMUSCLEGROWTHTHISSTUDYREPORTEDTHEHOMOLOGYOFMSTNGENEBETWEENTELEOSTANDMAMMALS,

9、纪九十年代发现的肌肉生长抑制素(MYOSTATIN,MSTN),又称生长分化因子8(GROWTHANDDIFFERENTIALFACTOR8)对生长具有负调控作用,是体内广泛表达的一种糖蛋白。MCPHERRON等2发现MSTN基因的CDNA中只有一个可读框(OPENINGREADINGFRAME,ORF),可编码376个氨基酸,它的结构具有TGF超家族的典型特征N端疏水的信号肽序列,可籍以跨越内质网膜,起分泌信号的作用;前区有一个糖基化位点;紧挨着生物活性区由4个氨基酸(RSRRARGSERARGARG)组成一个蛋白酶加工位点;C一端包含9个保守的半胱氨酸的生物活性区,靠分子间的二硫键形成二聚

10、体,即所谓的“CYSKNOT”的结构3,4。MSTN敲除的小鼠,其骨骼肌重量明显增加,是正常野生型小鼠的23倍左右。随后,MSTN的功能在双肌牛品种比利时蓝牛(BELGIANBLUE)和皮尔蒙特牛(PIEDMONTESE)得到进一步证明2。之后,MSTN的重要性以及其在动物育种中的潜在应用前景日益得到动物育种学家的关注,可以通过抑制MSTN的活性,提高养殖品种的肌肉含量,促进养殖品种的生长。以及近来研究发现MSTN基因还对脂肪沉积起抑制作用,与肌肉萎缩症、爱滋病等与肌肉有关的疾病相关5,6。而通过对多种鱼类的研究发现,鱼类MSTN产物在身体中的分布比哺乳动物MSTN在体内的分布更广泛,除了在骨

11、骼肌表达以外,还可以在多个组织中表达,如脑、肠、鳃、肾、性腺等等7。鱼类与哺乳动物的MSTN有不同的分布、表达方式,暗示其可能有不同于哺乳动物MSTN的功能。由于鱼类在系统发生过程中,有基因重复现象发生,从而导致MSTN产生两种基因型8。目前,对鱼类MSTN的研究较为深入,已在多种鱼类中克隆到MSTN,并对该基因的特征进行了一些分析,如斑马鱼(DANIORERIO)9,10、溪红点鲑(SALVELINMFONTINALIS)11,12,虹鳟(ONCORHYNCHUSMYKISS)13、大西洋鲑(SALMOSALAR)14、金头鲷(SPARUSAURATA)15,16、莫桑比克罗非鱼(OREOC

13、到越来越多重视。目前MSTN基因已经广泛用于哺乳动物系统进化分析,但将其用于鱼类系统进化研究的报道还不多。本研究利用生物信息学上的各种软件对鱼类MSTN基因进行氨基酸替换分析、同源性比较及进化树的构建,得到鱼类MSTN基因的进化特性,以期为研究鱼类肌肉发育调控和进化机理奠定基础。1材料与方法11不同物种MSTN基因序列检索通过NCBI(HTTP/WWWNCBINLMNIHGOV/)的GENBANK中读取鱼类、鸟类、哺乳类各物种的MSTN基因。见表1。表1进行序列分析的物种16物种(SPECIES)GENBANK登录号(GENBANKACCESSIONNO)编码蛋白数量(PROTIEN)MAMM
