The PI3K inhibitor buparlisib suppresses osteoclast formation and tumour cell growth in bone metastasis of lung cancer, as evidenced by multimodality molecular imaging.

Non‑small cell lung cancer (NSCLC) metastasis commonly occurs in bone, which often results in pathological fractures. Sustained phosphoinositide‑3‑kinase (PI3K) signalling promotes the growth of PI3K‑dependent NSCLC and elevates osteoclastogenic potential. The present study investigated the effects of a PI3K inhibitor on NSCLC growth in bone and osteoclast formation, and aimed to determine whether it could control symptoms associated with bone metastasis. A bone metastasis xenograft model was established by implanting NCI‑H460‑luc2 lung cancer cells, which contain a phosphatidylinositol‑​4,5‑b

Loss of EGFR activity in skeletal stem/progenitor cells is associated with impaired fracture healing in aged mice.

The cellular and molecular events responsible for fracture healing becoming delayed with aging remain unclear. Epidermal growth factor receptor (EGFR) signaling has been reported to play a critical role in bone regeneration. However, knowledge of its specific function in skeletal stem cells during aging-induced fracture delayed union remains scant. In the present study, we first demonstrated that EGFR activity in skeletal stem/progenitor cells decreased as mice aged and thus resulted in delayed fracture healing. To further investigate whether the EGFR signaling can be targeted as a potential t
