Osteocalcin as a treatment for frailty associated with aging

摘要

Methods and compositions for treating frailty in mammals, preferably humans, are provided. The methods generally involve modulation of the OST-PTP signaling pathway or the PTP-1B signaling pathway involving gamma-carboxylase and osteocalcin, e.g., by administration of undercarboxylated/uncarboxylated osteocalcin. The methods comprise alleviating at least one of: muscle wasting or a lung disorder while also alleviating at least one of: a metabolic disorder, a male reproductive disorder, or a cognitive disorder.
