Abstract

microRNAs (miRs) are targets for genomic aberrations and emerging treatments against cancer. It has been demonstrated that targeting miR‑569 may potentially benefit patients with ovarian or breast cancer. However, the exact roles of miR‑569 remain unclear in human lung cancer cells. Using the reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR), it was demonstrated that miR‑569 expression was consistently decreased in lung cancer cells. As well as cell proliferation and migration inhibition, apoptosis and cell arrest at the G1 phase were induced following reversion of miR‑569 expression in lung cancer cells. The present study demonstrated that miR‑569 was able to downregulate FOS and high mobility group A2 mRNA and protein expression using RT‑qPCR and western blot analysis. The observed role of miRNA‑569 in lung cancer cells in the present study suggested that it may be a novel and promising therapeutic target, and a novel biomarker for detecting lung cancer.
