Abstract

It has been reported that kindlin-3 expression is closely associated with progression of many cancers and microRNA (miRNA) processing. However, the effects and precise mechanisms of kindlin-3 in acute myeloid leukemia (AML) have not been well clarified. Our study aimed to explore the interaction between kindlin-3 and miR-4792 in AML. In our study, we found that the expression of kindlin-3 was dramatically increased in AML samples and cell lines, and the miR-4792 level was significantly downregulated. Interestingly, the low miR-4792 level was closely associated with upregulated kindlin-3 expression in AML samples. Moreover, introduction of miR-4792 dramatically suppressed proliferation and invasion and induced apoptosis of AML cells. We demonstrated that miR-4792 could directly target kindlin-3 by using both bioinformatics analysis and luciferase reporter assay. In addition, kindlin-3 silencing had similar effects with miR-4792 overexpression on AML cells. Overexpression of kindlin-3 in AML cells partially reversed the inhibitory effects of miR-4792 mimic. miR-4792 inhibited cell proliferation and invasion and induced apoptosis of AML cells by directly downregulating kindlin-3 expression, and miR-4792 targeting kindlin-3 was responsible for the regulation of the proliferation, invasion, and apoptosis of AML cells.

摘要

已有报道称，连接蛋白-3（kindlin-3）的表达与许多癌症的进展和 microRNA（miRNA）加工密切相关。然而，kindlin-3 在急性髓系白血病（AML）中的作用及其确切机制尚不清楚。本研究旨在探讨 kindlin-3 与 miR-4792 在 AML 中的相互作用。在本研究中，我们发现 kindlin-3 的表达在 AML 样本和细胞系中显著增加，而 miR-4792 的水平显著下调。有趣的是，miR-4792 水平较低与 AML 样本中上调的 kindlin-3 表达密切相关。此外，miR-4792 的引入可显著抑制 AML 细胞的增殖、侵袭并诱导其凋亡。我们通过生物信息学分析和荧光素酶报告基因检测证实，miR-4792 可直接靶向 kindlin-3。此外，沉默 kindlin-3 可产生与 miR-4792 过表达类似的 AML 细胞效应。AML 细胞中 kindlin-3 的过表达部分逆转了 miR-4792 模拟物的抑制作用。miR-4792 通过直接下调 kindlin-3 的表达抑制 AML 细胞的增殖和侵袭并诱导其凋亡，而 miR-4792 靶向 kindlin-3 负责调节 AML 细胞的增殖、侵袭和凋亡。
