研究目的:

基于临床实践中发现的新现象,研究AML中CLL-1表达率的高低对VEN敏感性的影响,并探索可能的机制,从而指导临床治疗。  

Objectives of Study:

Based on the new phenomena found in clinical practice, we aim to study the effect of CLL-1 expression on VEN sensitivity and its possible mechanisms in AML, in order to guide clinical treatment of AML.

药物成份或治疗方案详述:

1)构建敲除 CLL-1 的 AML 细胞系(THP1/HL-60),通过与不同浓度的VEN 共培养 24h 或 48h,利用 CCK8 法或流式细胞术检测 VEN 对 AML 细胞系和敲除 CLL-1 的 AML 细胞系的杀伤作用,比较 CLL-1 表达率高低的 AML 细胞系对 VEN 敏感性的差异。 2)选择难治复发且 CLL-1 表达双群(CLL-1 阳性和 CLL-1 阴性)的 AML患者,利用流式细胞仪或免疫磁珠法分选 CLL-1 阳性和 CLL-1 阴性的 AML 原代细胞,通过与不同浓度的 VEN 共培养 24h 或 48h,利用 CCK8 法或流式细胞术检测 VEN 对 CLL-1 阳性和 CLL-1 阴性的 AML 原代细胞的杀伤作用,比较CLL-1 表达率高低的 AML 原代细胞对 VEN 敏感性的差异。 

Description for medicine or protocol of treatment in detail:

1) An AML cell line (THP1/HL-60) with CLL-1 knockout was constructed, and the killing effect of VEN on AML cell lines and CLL-1 knockout AML cell lines was detected by CCK8 method or flow cytometry by co-culture with different concentrations of VEN for 24h or 48h, and the difference in sensitivity of AML cell lines with high and low CLL-1 expression rate to VEN was compared. 2) AML patients with refractory relapse and CLL-1 expression double populations (CLL-1 positive and CLL-1 negative) were selected, and CLL-1-positive and CLL-1-negative AML primary cells were sorted by flow cytometry or immunomagnetic bead method, and the killing effect of VEN on CLL-1-positive and CLL-1-negative AML primary cells was detected by CCK8 method or flow cytometry by co-culture with different concentrations of VEN for 24h or 48h, and the CLL-1 expression rate was compared Differences in the sensitivity of AML primary cells to VEN.
