MXD3 is a transcription factor that plays an important role in proliferation of human DAOY medulloblastoma cells. Here, we demonstrate that MXD3 is highly enriched in human precursor B acute lymphoblastic leukemia (preB ALL) samples compared to mobilized peripheral blood mononuclear cells, bone marrow, or hematopoietic stem cells from healthy donors. MXD3 knock-down in the preB ALL cell line Reh resulted in decreased cell numbers with no change in G0/G1, S or G2/M populations but increased apoptosis compared to control cells. Our results suggest that MXD3 is important for survival of Reh preB ALL cells, possibly as an anti-apoptotic factor.
MXD3是一种转录因子,在人类DAOY髓母细胞瘤细胞的增殖中发挥重要作用。在此,我们证明,与健康供体的动员外周血单个核细胞、骨髓或造血干细胞相比,MXD3在人类前体B急性淋巴细胞白血病(preB ALL)样本中高度富集。在preB ALL细胞系Reh中敲低MXD3导致细胞数量减少,G0/G1、S或G2/M期细胞群体无变化,但与对照细胞相比,细胞凋亡增加。我们的结果表明,MXD3对Reh preB ALL细胞的存活很重要,可能作为一种抗凋亡因子。
