Abstract: | Introduction Targeting joint destruction induced by osteoclasts (OCs) is critical for management of patients with rheumatoid arthritis
(RA). Since phosphoinositide 3-kinase (PI3-K) plays a critical role in osteoclastogenesis and bone resorption, we examined
the effects of ZSTK474, a novel phosphoinositide 3-kinase (PI3-K)-specific inhibitor, on murine OCs in vitro and in vivo. |
