[摘 要] T细胞急性淋巴细胞白血病(T⁃cell acute lymphoblastic leukemia,T⁃ALL)是一种高侵袭性血液肿瘤,分别占儿童和
成人ALL病例总数的15%和25%。在T⁃ALL中,约60%的病例发生NOTCH1突变。NOTCH1通过脯氨酸、谷氨酸、丝氨酸、苏
氨酸富集基元(a cluster of proline,glutamic acid,serine,and threonine residues,PEST)结构域截断或异源二聚化异常,导致胞内
活性片段(NOTCH intracellular domain,NICD)无法降解或持续释放,下游靶基因(如MYC)被异常激活,并与TAL1、LMO2等致
癌因子协同,驱动白血病发生。在靶向NOTCH1的治疗策略中,γ⁃分泌酶抑制剂因广谱毒性受限,而新型PSEN1选择性抑制剂
(MRK⁃560)、NOTCH1单抗(OMP⁃52M51)及小分子CB⁃103可通过精准抑制信号转导,显著降低毒性。此外,代谢干预与表观
调控方面也展现出协同潜力。近年来,关于NOTCH1信号通路在T⁃ALL中的研究取得了显著进展,但还需要更多研究来揭示
其中的奥秘。文章重点介绍NOTCH1突变对T⁃ALL细胞造成的影响及靶向NOTCH1信号通路的相关药物,并探讨NOTCH1通
路与耐药的相关性。

[Abstract] T⁃cell acute lymphoblastic leukemia(T⁃ALL)is a highly aggressive hematologic malignancy,accounting for approximately
15% and 25% of all pediatric and adult ALL cases,respectively. In T⁃ALL,approximately 60% of cases have NOTCH1 mutations.
These mutations,caused by truncation of the PEST(a cluster of proline,glutamic acid,serine,and threonine residues)domain or
abnormal heterodimerization,lead to impaired degradation or persistent release of the NOTCH intracellular domain(NICD),resulting
in aberrant activation of downstream target genes such as MYC. This process synergizes with oncogenic factors like TAL1 and LMO2 to
drive leukemogenesis. Among therapeutic strategies targeting NOTCH1,γ ⁃ secretase inhibitors have been limited by their broad ⁃
spectrum toxicity. However,novel agents such as the PSEN1⁃selective inhibitor MRK⁃ 560,NOTCH1 monoclonal antibody(OMP⁃
52M51),and the small molecule CB⁃103 demonstrate precise inhibition of NOTCH1 signaling with reduced toxicity. Additionally,
metabolic interventions and epigenetic regulation have shown synergistic potential. Although significant progress has been made in
understanding the role of the NOTCH1 signaling pathway in T⁃ALL,further research is needed to unravel its complexities. This review
focuses on the impact of NOTCH1 mutations on T ⁃ ALL cells,discusses drugs targeting the NOTCH1 pathway,and explores the
association between NOTCH1 signaling and drug resistance.
