Abstract

MicroRNAs (miRNAs/miRs) are frequently differentially expressed in non‑small cell lung cancer (NSCLC), and differential miRNAs expression may be closely associated with NSCLC genesis and development. Therefore, an in‑depth investigation of the cancer‑associated miRNAs that are crucial for NSCLC pathogenesis may provide effective therapeutic targets for patients with this aggressive malignant tumor type. The expression levels and roles of miR‑877 have been well studied in hepatocellular carcinoma and renal cell carcinoma. However, the expression pattern and functions of miR‑877 in NSCLC as well as associated underlying mechanisms, to the best of our knowledge, have not yet been investigated. The present study revealed that miR‑877 expression was downregulated in NSCLC tissues and cell lines. Low miR‑877 expression was significantly associated with TNM stage and distant metastasis in patients with NSCLC. Functional experiments demonstrated that recovery of miR‑877 expression restricted the proliferation and invasion of NSCLC cells. In addition, bioinformatics analysis predicted insulin‑like growth factor 1 receptor (IGF‑1R) as a potential target of miR‑877. Luciferase reporter assays, reverse transcription‑quantitative PCR and western blot analysis further validated that IGF‑1R was a direct target of miR‑877 in NSCLC. Furthermore, IGF‑1R expression was markedly upregulated in NSCLC tissues, and exhibited an inverse correlation with miR‑877 expression. Additionally, IGF‑1R overexpression reversed the inhibitory effects in NSCLC cells caused by miR‑877 upregulation. These findings demonstrated that miR‑877 attenuated NSCLC cell proliferation and invasion, at least partly, by downregulating IGF‑1R expression, thereby providing an new candidate biomarker for the diagnosis and therapy of patients with NSCLC.
