摘要

目的 探讨神经前体细胞表达发育下调样蛋白4(NEDD4L)调控Wnt/β-catenin通路对急性髓系白血病(AML)细胞增殖和凋亡的影响。 方法 利用慢病毒转染技术构建稳定过表达及敲低NEDD4L的Kasumi-1和U937细胞系;通过RT-qPCR和Western blot验证NEDD4L过表达及敲低效率;CCK-8实验检测Kasumi-1和U937细胞的增殖情况;流式细胞术检测Kasumi-1和U937细胞凋亡改变;Western blot检测凋亡蛋白BAX、Bcl2及Wnt/β-catenin通路中关键蛋白β-catenin、c-Myc、cyclin D1的表达。 结果 RT-qPCR和Western blot结果提示,Kasumi-1和U937细胞系中NEDD4L成功过表达和敲低(P < 0.05)。CCK-8结果提示NEDD4L过表达显著抑制Kasumi-1和U937细胞增殖能力(P < 0.05)。流式细胞术结果表明,NEDD4L过表达后Kasumi-1和U937细胞凋亡率显著升高。Western blot结果提示,过表达NEDD4L可上调凋亡蛋白BAX、下调抗凋亡蛋白Bcl2表达(P < 0.05)。机制研究表明,过表达NEDD4L可降低β-catenin、c-Myc、cyclin D1的表达,而敲低NEDD4L则上调上述蛋白。此外,Wnt/β-catenin通路激动剂SKL2001可部分逆转过表达NEDD4L所致的通路抑制效应(P < 0.05)。 结论 NEDD4L通过抑制Wnt/β-catenin通路活性,从而抑制AML细胞增殖、诱导AML细胞凋亡。提示NEDD4L可能是AML潜在的治疗靶点。

Abstract

Objective To investigate the effect of NEDD4L on the proliferation and apoptosis of acute myeloid leukemia (AML) cells and its underlying mechanism via the regulation of the Wnt/β-catenin pathway. Methods Stable NEDD4L-overexpressing and NEDD4L-knockdown Kasumi-1 and U937 cell lines were successfully established via lentiviral transduction technology. The efficiency of NEDD4L overexpression and knockdown was rigorously verified by RT-qPCR and Western blot. Cell proliferation was accurately assessed using the CCK-8 assay, and apoptosis was precisely detected through flow cytometry. The expression levels of the apoptosis-related proteins BAX and Bcl2, along with the key proteins of the Wnt/β-catenin pathway (β-catenin, c-Myc, and cyclin D1), were measured by Western blot. Results Results from RT-qPCR and Western blot assays demonstrated that NEDD4L was successfully overexpressed and knocked down in Kasumi-1 and U937 cell lines (P < 0.05). CCK-8 assay results indicated that overexpression of NEDD4L significantly inhibited the proliferative capacity of Kasumi-1 and U937 cells (P < 0.05). Flow cytometry results showed that overexpression of NEDD4L significantly increased the apoptosis rate in Kasumi-1 and U937 cells. Western blot analysis results revealed that overexpression of NEDD4L upregulated the pro-apoptotic protein BAX and downregulated the anti-apoptotic protein Bcl2 (P < 0.05). Mechanistic studies results showed that overexpression of NEDD4L decreased the expression of β-catenin, c-Myc, and cyclin D1, whereas knockdown of NEDD4L upregulated these proteins. Furthermore, the Wnt/β-catenin pathway agonist SKL2001 partially reversed the pathway inhibition induced by overexpression of NEDD4L (P < 0.05). Conclusion NEDD4L inhibits the proliferation of AML cells and induces the apoptosis of AML cells by suppressing the activity of the Wnt/β-catenin pathway, which suggests that NEDD4L may serve as a potential therapeutic target for AML.
