摘要
目的研究整合素β1及局部粘附激酶(FAK)在慢性髓系白血病(CML)进展过程中的变化及干扰素治疗对FAK的可能作用。方法(1)应用流式细胞仪检测正常对照组、CML慢性期组及CML急变组骨髓CD34+细胞的胞膜表面CD29及胞质FAK表达量;(2)将正常对照及CML慢性期骨髓单个核细胞分为IFN处理组及非处理组培养48 h后提取总蛋白,应用Western blotting检测FAK含量变化。结果(1)CML慢性期骨髓CD34+细胞表面CD29的表达与对照组无显著差异,而胞内FAK含量则下降;(2)CML急变期骨髓CD34+细胞表面CD29的表达较慢性期明显升高而胞内FAK含量则较慢性期进一步下降;(3)IFN处理前后正常骨髓单个核细胞FAK的含量无明显差异;(4)IFN处理后CML骨髓单个核细胞FAK含量较未处理组明显上升。结论整合素β1及FAK表达变化可能是CML进展恶化的原因之一,而IFN-α可能通过恢复FAK含量来改善β1受体介导的粘附信号通路的缺陷。
