生长分化因子受体、其激动剂和拮抗剂及其使用方法
摘要：
本发明是生长分化因子受体、其激动剂和拮抗剂及其使用方法。本发明提供了一种基本上纯化的生长分化因子(GDF)受体，包括GDF－8(肌生长抑制素myostatin)受体，以及其功能性肽部分。另外，本发明提供了GDF受体或其功能性肽部分的一种虚拟表现形式。本发明还提供了一种通过将细胞与影响肌生长抑制素在细胞中信号转导的药物接触调节肌生长抑制素细胞效应的方法。另外，本发明提供了一种通过在受者肌肉细胞或脂肪组织细胞中调节肌生长抑制素信号转导改善严重病理状况的方法，该病理状况至少部分地以受者肌肉或脂肪组织中异常的重量、发育或代谢活性为特征。本发明也提供了一种在真核细胞生物体中，通过给生物体使用一种影响肌生长抑制素信号转导的药物，调节肌肉组织或脂肪组织生长的方法。
摘要（英）：

The present invention relates to growth differentiation factor receptors, agonists and antagonists thereof, and methods of using same. The present invention provides a substantially purified growth differentiation factor (GDF) receptor, including a GDF-8 (myostatin) receptor, as well as functional peptide portions thereof. In addition, the invention provides a virtual representation of a GDF receptor or a functional peptide portion thereof. The present invention also provides a method of modulating an effect of myostatin on a cell by contacting the cell with an agent that affects myostatin signal transduction in the cell. In addition, the invention provides a method of ameliorating the severity of a pathologic condition, which is characterized, at least in part, by an abnormal amount, development of metabolic activity of muscle or adipose tissue in a subject, by modulating myostatin signal transduction in a muscle cell or an adipose tissue cell in the subject. The invention also provides a method of modulating the growth of muscle tissue or adipose tissue in a eukaryotic organism by administering an agent that affects myostatin signal transduction to the organism.
