Our previous studies showed that the angiogenic integrin αvβ3 was increased in high-risk metastatic (stage 4) NB compared with localized neuroblastomas. Herein, we show that integrin αvβ3 was expressed on 68% of microvessels in MYCN-amplified stage 3 neuroblastomas, but only on 34% (means) in MYCN-non-amplified tumors (p %K BRD4 %K PI3-kinase inhibitors %K angiogenesis %K integrin αvβ3 %K neuroblastoma %~
