A genetics approach has uncovered that bone has more functions than expected. In particular, bone is an endocrine organ secreting a growing number of hormones. In that context the discovery of the osteoblast-derived hormone osteocalcin has significantly broadened the field of bone biology because of the number of physiological processes regulated by this hormone. At present, osteocalcin has been shown to enhance several aspects of energy metabolism, brain development and cognition. As a whole, these discoveries shed light on the cross-talk between multiple organs and provide credence to the search of additional endocrine functions of bone...

Sarcopenia is defined as low muscle function (walking speed or grip strength) in the presence of low muscle mass. A simple screening test - the SARC-F - is available to identify persons with sarcopenia. The major endocrine causes of sarcopenia are diabetes mellitus and male hypogonadism. Other causes are decreased physical activity, loss of motor neuron units, weight loss, inflammatory cytokines, reduced blood flow to muscles, very low 25(OH) vitamin D levels and decreased growth hormone and IGF-1. Treatment for sarcopenia includes resistance and aerobic exercise, leucine enriched essential amino acids, and vitamin D...
