In this issue of Blood, Goussetis et al identify autophagy as a new pathway for the degradation of the oncoprotein BCR-ABL. They show that the therapeutic drug arsenic trioxide (AS(2)O(3)) targets BCR-ABL for autophagic degradation via a p62/SQSTM1-dependent mechanism that is critical for the antileukemic effect of the drug.
在本期《Blood》中,Goussetis 等人确定自噬是降解致癌蛋白 BCR-ABL 的新途径。他们表明,治疗药物三氧化二砷(AS(2)O(3))通过依赖 p62/SQSTM1 的机制靶向 BCR-ABL 进行自噬降解,该机制对于药物的抗白血病作用至关重要。
