Mammalian target of rapamycin (mTOR) functions mainly in the form of two complexes, namely mTORC1 and mTORC2, which are distinct in their unique components, raptor and rictor. Here, we focused on bone phenotypes in mice with a specific deletion of rictor using a Cre recombinase gene whose expression was driven by the promoter of osteocalcin. All procedures involving mice were approved by the Institutional Animal Care and Use Committee of the local admin. DXA analysis showed a ...

Irisin is a hormone-like myokine secreted from skeletal muscle in response to exercise. Considering that an intimate relationship between skeletal muscle and bone has been well established and that physical exercise physiologically stimulates the skeleton strengthening, we explored the involvement of Irisin on bone metabolism.Our findings demonstrated that the myokine Irisin improves cortical bone mass and geometry in vivo, supporting the idea t...
