Atg5/Autophagy inactivation in mouse bone microenvironment promotes tumor development.

Bone is an attractive site for cancer colonization, both for primary tumors such as osteosarcoma and for metastases of various malignancies. Preventing bone metastasis, which is associated with a poor prognosis, is a major challenge and identifying the factors involved in skeletal tumoral development is crucial to improve survival. In the present work, we showed that inactivation of the macroautophagy/autophagy-essential gene
