Numerous studies confirmed that aberrant microRNA (miRNA) expression contributes to cancer development and progression. We carried out this study to explore the expression profile of miRNAs in intermediate risk acute myeloid leukemia (AML) and locate certain miRNAs as biomarkers. We profiled differentially expressed miRNAs by performing miRNA sequencing analysis in the patients’ samples. Bioinformatic analysis showed the most significantly expressed genes mostly involved in cellular component organization, cell differentiation, and cell development. Reverse‐transcription polymerase chain reaction validated the expression of miR‐582‐5p in different groups of AML samples. It was confirmed that miR‐582‐5p was downregulated in newly diagnosed AML and relapse/refractory AML compared with CR AML or controls. Among intermediate risk AML patients with normal cytogenetics, a lower level of miR‐582‐5p is correlated with an unfavorable outcome, and a shorter overall survival. Gain‐ and loss‐of‐function experiments revealed that miR‐582‐5p could inhibit proliferation, suppress migration, and invasion ability and induce apoptosis of leukemia cells. Furthermore, overexpression of miR‐582‐5p can increase sensitivity of cells to Ara‐C. In conclusion, miR‐582‐5p can serve as an antioncogenic biomarker in intermediate risk AML with normal cytogenetics for risk classification and outcome prediction. These results showed a novel role for miR‐582‐5p in predicting the prognosis and promoting the tumor growth of AML.

miR-582-5p 作为细胞遗传学正常的中等风险 AML 的抗癌生物标志物,可以抑制白血病细胞的增殖和诱导细胞凋亡。

许多研究证实,异常的微小 RNA (miRNA) 表达有助于癌症的发展和进展。我们开展这项研究是为了探索中危急性髓系白血病 (AML) 中 miRNA 的表达谱,并定位某些 miRNA 作为生物标志物。我们通过在患者样本中进行 miRNA 测序分析来分析差异表达的 miRNA。生物信息学分析显示表达最显着的基因主要涉及细胞成分组织、细胞分化和细胞发育。逆转录聚合酶链反应验证了 miR-582-5p 在不同组 AML 样本中的表达。证实与 CR AML 或对照相比,miR-582-5p 在新诊断的 AML 和复发/难治性 AML 中下调。在细胞遗传学正常的中等风险 AML 患者中,较低水平的 miR-582-5p 与不利的结果和较短的总生存期相关。功能获得和丧失实验表明,miR-582-5p 可以抑制白血病细胞的增殖、抑制迁移和侵袭能力并诱导其凋亡。此外,miR-582-5p 的过表达可以增加细胞对 Ara-C 的敏感性。总之,miR-582-5p 可以作为中危 AML 的抗癌生物标志物,具有正常的细胞遗传学,用于风险分类和结果预测。这些结果显示了 miR-582-5p 在预测 AML 预后和促进肿瘤生长方面的新作用。功能获得和丧失实验表明,miR-582-5p 可以抑制白血病细胞的增殖、抑制迁移和侵袭能力并诱导其凋亡。此外,miR-582-5p 的过表达可以增加细胞对 Ara-C 的敏感性。总之,miR-582-5p 可以作为中危 AML 的抗癌生物标志物,具有正常的细胞遗传学,用于风险分类和结果预测。这些结果显示了 miR-582-5p 在预测 AML 预后和促进肿瘤生长方面的新作用。功能获得和丧失实验表明,miR-582-5p 可以抑制白血病细胞的增殖、抑制迁移和侵袭能力并诱导其凋亡。此外,miR-582-5p 的过表达可以增加细胞对 Ara-C 的敏感性。总之,miR-582-5p 可以作为中危 AML 的抗癌生物标志物,具有正常的细胞遗传学,用于风险分类和结果预测。这些结果显示了 miR-582-5p 在预测 AML 预后和促进肿瘤生长方面的新作用。miR-582-5p 可作为中危 AML 的抗癌生物标志物,细胞遗传学正常,用于风险分类和结果预测。这些结果显示了 miR-582-5p 在预测 AML 预后和促进肿瘤生长方面的新作用。miR-582-5p 可作为中危 AML 的抗癌生物标志物,细胞遗传学正常,用于风险分类和结果预测。这些结果显示了 miR-582-5p 在预测 AML 预后和促进肿瘤生长方面的新作用。
