Many researches revealed that microRNAs (miRNAs) function as potential oncogene or tumor suppressor gene. As an antioncogene, miR-877-5p was reduced in many tumors.
This research aimed to explore the biological role and mechanisms of miR-877-5p, which may help patients with non-small-cell lung cancer (NSCLC) find effective therapeutic targets.
The downstream targets of miR-877-5p were predicted by Bioinformatics software. RT-qPCR and western blot were employed to analyze the gene levels. The impacts of miR-877-5p and FOXM1 were assessed by cell function experiments.
The miR-877-5p was reduced in NSCLC. In addition to this, it also inhibited cell progression of NSCLC cells . Moreover, the upregulation of FOXM1 expression restored the inhibitory effect of enhancement of miR-877-5p.
Taken together, miR-877-5p inhibited cell progression by directly targeting FOXM1, which may provide potential biomarkers for targeted therapy of NSCLC.
许多研究表明 microRNAs(miRNAs)可作为潜在的癌基因或肿瘤抑制基因发挥作用。miR-877-5p 作为一种抑癌基因,在许多肿瘤中表达降低。
本研究旨在探讨 miR-877-5p 的生物学功能和作用机制,以期为非小细胞肺癌(NSCLC)患者寻找有效的治疗靶点。
生物信息学软件预测 miR-877-5p 的下游靶基因。采用 RT-qPCR 和 Western blot 检测基因水平。通过细胞功能实验评估 miR-877-5p 和 FOXM1 的影响。
miR-877-5p 在 NSCLC 中表达降低,并且能够抑制 NSCLC 细胞的进展。此外,上调 FOXM1 的表达可以恢复 miR-877-5p 增强对细胞进展的抑制作用。
miR-877-5p 通过直接靶向 FOXM1 抑制细胞进展,可能为 NSCLC 的靶向治疗提供潜在的生物标志物。
