In addition, the Notch pathway plays an important role in controlling tumorigenesis. However, the role of RBPJ, a transcription factor in the Notch pathway, in the development of tumors is largely unknown. In this study, we focused on the role of RBPJ in the pathogenesis of rhabdomyosarcoma (RMS). Our data showed that Notch pathway genes were upregulated and activated in human RMS cell lines and patient samples. Inhibition of the Notch pathway by a csecretase inhibitor (GSI) decreased the in vitro proliferation of RMS cells. Knockdown of RBPJ expression by RNAi inhibited the anchorage-independent growth of RMS cells and the growth of xenografts in vivo. Additionally, overexpression of RBPJ promoted the anchorage-independent growth of RMS cells. Further, we revealed that RBPJ regulated the cell cycle in RMS xenograft tumors and decreased proliferation. Our findings suggest that RBPJ regulates the RMS growth, and that the inhibition of RBPJ may be an effective therapeutic approach for patients with RMS.}, title = {RBPJ Is a Novel Target for Rhabdomyosarcoma Therapy}, volume = {7}, year = {2012}, yomi = {ナガオ, ヒロコ and セトグチ, タカオ and キタモト, ショウ and イシドウ, ヤスヒロ and ナガノ, サトシ and ヨコウチ, マサヒロ and アベマツ, マサヒコ and カワバタ, ナオヤ and マエダ, シンゴ and ヨネザワ, スグル and コミヤ, セツロウ} }
