Abstract

Hepatocellular carcinoma (HCC) is a cancer with a poor prognosis and a low survival rate. Previous studies have found that microRNA‑1266 (miR‑1266) is associated with tumorigenesis and progression of several types of cancer, such as breast cancer and gastric cancer. The aim of the present study was to investigate the effects of miR‑1266 on the clinical prognosis and biological behavior of HCC. For this purpose, reverse transcription‑quantitative PCR was used to detect the expression of miR‑1266 in HCC tissues and HCC cell lines. In addition, Kaplan‑Meier survival analysis and Cox regression analysis were used to evaluate the prognostic value of miR‑1266. Cell Counting Kit‑8 (CCK‑8) and Transwell assays were used to analyze the effect of miR‑1266 on the biological behavior of cells. The aforementioned assays demonstrated that the examined HCC tissues had a significant upregulation of miR‑1266 expression compared with normal tissues (P<0.001). The overexpression of miR‑1266 was significantly associated with Tumor‑Node‑Metastasis stage (P=0.014). The results of the Kaplan‑Meier analysis indicated that the 5‑year overall survival rate of patients with high expression of miR‑1266 was significantly lower compared with patients with low expression of miR‑1266 (P=0.015). Cox regression analysis demonstrated that the expression level of miR‑1266 could be used as an independent prognostic factor of HCC. CCK‑8 and Transwell assays demonstrated that overexpression of miR‑1266 promoted the proliferation, migration and invasion of HCC cells. In summary, the findings of the present study indicated that high expression of miR‑1266 was positively associated with poor prognosis of patients with HCC and promoted cell proliferation, migration and invasion of HCC cells. miR‑1266 may be used as a biomarker for HCC prognosis.
