肌肉生长抑制素基因 分子进化 同源模建
2009/7/2
Myostatin(MST)为肌肉生长负调节因子，其功能受抑制可导致肌肉量增加。对MST核酸序列进行序列比对，构建进化树；采用同源模建方法首次模建MST成熟肽生物活性二聚体的四级结构，并预测MST与其受体ActRIIB的相互作用模式。进化树将肌肉生长抑制素基因（MSTN）分成4个亚家族：哺乳动物MSTN，鸟类MSTN以及鱼类MSTN 1和2。MST受纯化选择作用，在不同物种的直系同源基因具有较高...

进行性肌营养不良患者Myostatin基因的表达分析
进行性肌营养不良 肌肉抑制素基因 蛋白加工
2008/1/30
摘要进行性肌营养不良是一组以进行性骨骼肌萎缩和无力为特征的肌源性肌病。肌肉抑制素（Myostatin）是最近发现的骨骼肌生长发育抑制因子。为探讨Myostatin基因与进行性肌营养不良病理发生的相关性，采用RT-PCR方法克隆了患者的Myostatin基因并测序，分析肌营养不良患者是否存在Myostatin基因突变；然后采用半定量RT-PCR方法检测患者中Myostatin基因的表达水平是否发生改...
鸡Myostatin基因单核苷酸多态性的群体遗传学分析
鸡 Myostatin基因 单核苷酸多态性
2008/1/29
摘要肌肉生长抑制素是控制骨骼肌生长发育的重要细胞因子,采用PCR-SSCP和测序的方法发现了5个位于Myostatin基因5'-和3'-调控区的单核苷酸多态性位点,对北京油鸡、白耳鸡、石歧杂、矮小黄鸡、小型黄鸡、惠阳胡须鸡、隐性白羽鸡、海兰、AA鸡等不同鸡种的该单核苷酸多态性分析结果表明:Myostatin基因的5'调控区引物P60/P61扩增片段多态性是由3个核苷酸的改变而产生的[分别是G→A(...
