Disclosed is a composition for promoting local muscle growth or slowing down or preventing local muscle atrophy, which composition contains a polypeptide in the C2 region of the enterotoxin Staphylococcus aureus and a myostatin polypeptide. By means of the composition, the defect in the prior art of only systemic muscle growth being possible has been overcome so as to achieve effects of promoting local muscle growth, or slowing down or preventing local muscle atrophy.

The present disclosure relates to a non-therapeutic use of whey protein micelles to enhance muscle protein synthesis in a subject. Further aspects are directed to food compositions comprising whey protein micelles to be administered to children, athletes, or elderly persons.

The present invention relates to novel polymethoxyflavone compounds for improving skeletal muscle plasticity regeneration to maintain or increase muscle function and/or muscle mass by modulating muscle stem cells. For example, the present invention is useful for subjects to promote muscle repair and/or subjects suffering from precachexia, cachexia, sarcopenia, myopathy, dystrophy and/or recovery after muscle injury or surgery.

An extract of Citrus depressa, preferably a water and/or organic solvent extract of a fruit of leaf of Citrus depressa, a supercritical extract of a fruit of leaf of Citrus depressa, or a subcritical extract of a fruit of leaf of Citrus depressa, which comprise 0.3 mass % or more of a polymethoxyflavonoid more than in terms of solid matter, for example, an extract of Citrus depressa comprising 0.2 mass % or more of nobiletin and/or 0.1 mass % or more of tangeretin in terms of solid matter, or a polymethoxyflavonoid such as nobiletin or tangeretin is used as an active ingredient of an IGF-1 production-promoting agent.

The invention provides methods for inducing, enhancing or increasing satellite cell proliferation, and an assay for screening for a candidate compound for inducing, enhancing or increasing satellite cell proliferation. Also provided are methods for repairing or regenerating a damaged muscle tissue of a subject.

The present invention is directed to therapeutic methods using IL-6 antagonists such as antibodies and fragments thereof having binding specificity for IL-6 to improve survivability or quality of life of a patient in need thereof. In preferred embodiments these patients will comprise those exhibiting (or at risk of developing) an elevated serum C-reactive protein level or a reduced serum albumin level prior to treatment. In another preferred embodiment, the patient's Glasgow Prognostic Score will be increased and survivability will preferably be improved.
