摘要
T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive subset of ALL with poor clinical outcome compared to B-ALL. Therefore, to improve treatment, it is imperative to delineate the molecular blueprint of this disease. This review describes the central role that the Notch pathway plays in T-ALL development. We also discuss the interactions between Notch and the tumor suppressors Ikaros and p53. Loss of Ikaros, a direct repressor of Notch target genes, and suppression of p53-mediated apoptosis are essential for development of this neoplasm. In addition to the activating mutations of Notch previously described, this review will outline combinations of mutations in pathways that contribute to Notch signaling and appear to drive T-ALL development by ‘mimicking’ Notch effects on cell cycle and apoptosis.
