白血病细胞受到其微环境的各种成分的保护,包括骨髓基质细胞(MSCs)。为了了解这种保护的分子机制,我们用MSCs培养急性淋巴细胞白血病(ALL)细胞,并在mRNA和蛋白质水平上研究了后者对ALL细胞分子图谱的影响。我们的结果表明,所有细胞中激活的Wnt信号参与了MSC介导的耐药。在小鼠模型中,阻断Wnt通路使白血病细胞对化疗敏感,并提高了总体存活率。靶向Wnt通路可能是治疗ALL的一种创新方法。
Leukemia cells are protected by various components of its microenvironment, including marrow stromal cells (MSCs). To understand the molecular mechanisms underlying this protection, we cultured acute lymphoblastic leukemia (ALL) cells with MSCs and studied the effect of the latter on the molecular profiling of ALL cells at the mRNA and protein levels. Our results indicated that activated Wnt signaling in ALL cells is involved in MSC-mediated drug resistance. Blocking the Wnt pathway sensitized the leukemia cells to chemotherapy and improved overall survival in a mouse model. Targeting the Wnt pathway may be an innovative approach to the treatment of ALL.
