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 or 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.

Anti-myostatin antibodies are identified that are characterized as having high affinity and may be chimeric, humanized or fully human antibodies, immunoconjugates of the antibodies or antigen-binding fragments thereof. The antibodies of the invention are useful for increasing muscle mass, increasing bone density, or for the treatment of various disorders in mammalian and avian species.

The present invention provides variant activin IIB soluble receptor polypeptides and proteins capable of binding and inhibiting the activities of activin A, myostatin, or GDF-11. The present invention also provides polynucleotides, vectors and host cells capable of producing the variant polypeptides and proteins. Compositions and methods for treating muscle-wasting and other diseases and disorders are also provided.

A method and compound for treating skeletal muscle mass deficiency in a human subject are disclosed. The composition is an oligomer of morpholino subunits and phosphorus-containing intersubunit linkages joining a morpholino nitrogen of one subunit to a 5′ exocyclic carbon of an adjacent subunit, contains between 10-40 nucleotide bases, has a base sequence effective to hybridize to an expression-sensitive region of processed or preprocessed human myostatin RNA transcript, identified, in its processed form, by SEQ ID NO:6, and is capable of uptake by target muscle cells in the subject. In practicing the method, the compound is administered in an amount and at a dosage schedule to produce an overall reduction in the level of serum myostatin measured in the patient, and preferably to bring the myostatin level within the a range determined for normal, healthy individuals.

The present invention provides variant activin IIB soluble receptor polypeptides and proteins capable of binding and inhibiting the activities of activin A, myostatin, or GDF-11. The present invention also provides polynucleotides, vectors and host cells capable of producing the variant polypeptides and proteins. Compositions and methods for treating muscle-wasting and other diseases and disorders are also provided.

A neutralizing epitope is identified within amino acids 40-64 of the mature form of human myostatin. Antibodies that bind this epitope with high affinity preferentially bind GDF-8 over GDF-11 and may be chimeric, humanized or fully human antibodies, immunoconjugates of the antibodies or antigen-binding fragments thereof. The antibodies of the invention are useful for increasing muscle mass, increasing bone density, or for the treatment of various disorders in mammalian and avian species.

The present invention relates to fibronectin-based scaffold domain proteins that bind to myostatin. The invention also relates to the use of these proteins in therapeutic applications to treat muscular dystrophy, cachexia, sarcopenia, osteoarthritis, osteoporosis, diabetes, obesity, COPD, chronic kidney disease, heart failure, myocardial infarction, and fibrosis. The invention further relates to cells comprising such proteins, polynucleotides encoding such proteins or fragments thereof, and to vectors comprising the polynucleotides encoding the proteins.

The present invention relates to a method of treating sarcopenia in a human or animal patient by inhibiting the activity of myostatin using one or more myostatin antagonists.

Disclosed are novel methods for increasing muscle mass by means of immunization against Growth Differentiation Factor 8 (GDF-8, myostatin). Immunization is preferably effected by administration of analogues of GDF-8 which are capable of inducing antibody production against homologous GDF-8. Especially preferred as an immunogen is homologous GDF-8 which has been modified by introduction of one single or a few foreign, immunodominant and promiscuous T-cell epitopes while substantially preserving the tertiary structure of the homologous GDF-8. Also disclosed are nucleic acid vaccination against GDF-8 and vaccination using live vaccines as well as methods and means useful for the vaccination. Such methods and means include methods for identification of useful immunogenic GDF-8 analogues, methods for the preparation of analogues and pharmaceutical formulations, as well as nucleic acid fragments, vectors, transformed cells, polypeptides and pharmaceutical formulations.

Myostatin antagonists, including myostatin binding antibodies, are disclosed. Also disclosed are nucleic acids encoding and cells including myostatin antagonists; methods of production; and methods of use.

The invention relates to methods and materials for enhancing muscle mass or for the treatment of muscle disease in a subject, comprising introducing a cell which has a lower than normal level of myostatin signalling, into the subject.

Description of antigen binding proteins, such as antibodies, which bind to myostatin, polynucleotides encoding such antigen binding proteins, pharmaceutical compositions comprising said antigen binding proteins and methods of manufacture. Furthermore, description of the use of such antigen binding proteins in the treatment or prophylaxis of diseases associated with any one or a combination of decreased muscle mass, muscle strength and muscle function.
