Phosphatidyl inositol 3-kinase (PI3K)-mTOR inhibitor PKI-402 inhibits breast cancer induced osteolysis.

    Bone metastasis causes bone pain and pathological bone fracture in breast cancer patients with a serious complication. Previous studies have demonstrated that a novel phosphatidyl inositol 3-kinase (PI3K)-mTOR inhibitor PKI-402 suppressed the growth of breast cancer cells. However, the role of PKI-402 involved in osteolysis induced by breast cancer remains unclear. In this study, we showed that treatment of PKI-402 led to significant decreases in RANKL-induced osteoclastogenesis and osteoclast-specific gene expression in mouse bone marrow-derived macrophages and reduced proliferation, migration and invasion of MDA-MB-231 breast cancer cells by blocking the PI3K-AKT-mTOR signaling pathway. Importantly, as evidenced by the observation that the administration of PKI-402 inhibited MDA-MB-231-induced osteolysis in vivo, PKI-402 exerted an inhibitory effect on osteoclast formation and bone resorption, critical for cancer cells-induced bone destruction. These results strongly suggest that PKI-402 might have a therapeutic potential to inhibit breast cancer induced osteolysis.
