摘要: Medulloblastoma (MB) expresses Src kinase, while aurora kinase A overexpression correlates with poor survival. We thus investigated novel combination treatment dasatinib and AT9283, inhibitors of respectively, on MB growth in vitro vivo. Treatment each drug significantly reduced cell viability combined markedly potentiated this response. AT9283 induced p53 expression, autophagy, G2/M cell-cycle arrest, S phase arrest. Dasatinib caused tumor regression Activated was detected 44% analyzed. conclude that further evaluation therapy for is highly warranted.
