In this issue of , Anand et al provide compelling evidence that resistance to Notch inhibitor therapy in early T-cell precursor acute lymphoblastic leukemia (ETP-ALL) occurs as a result of an activated phosphatidylinositol 3-kinase (PI3K) pathway. To further decipher the resistance mechanism, the investigators performed single-cell RNA sequencing analysis on the bone marrow of 5 patients treated with the γ-secretase inhibitor (GSI) BMS-906024 and found 13 different cell clusters, of which 6 were specific to leukemia patients.
在本期《》中,Anand 等人提供了令人信服的证据,表明早期 T 细胞前体急性淋巴细胞白血病(ETP-ALL)对 Notch 抑制剂治疗的耐药性是由于磷酸肌醇 3-激酶(PI3K)途径的激活所致。为了进一步解析耐药机制,研究人员对 5 例接受 γ-分泌酶抑制剂(GSI)BMS-906024 治疗的患者的骨髓进行了单细胞 RNA 测序分析,发现了 13 个不同的细胞簇,其中 6 个是白血病患者所特有的。
