Abstract

MicroRNAs (miRNAs/miRs) have important roles in tumor progression in various human cancers. Ultrasound‑targeted microbubble destruction (UTMD)‑mediated gene transfection has been considered a useful tool for improving cancer treatment. The present study aimed to investigate the role of miR‑767 in non‑small cell lung cancer (NSCLC) and further analyze the effects of UTMD‑mediated miR‑767 inhibition on tumor progression. The expression of miR‑767 was measured by reverse transcription‑quantitative PCR. UTMD‑mediated miR‑767 inhibition was achieved by the co‑transfection of microbubbles and miR‑767 inhibitor in NSCLC cells. Cell proliferation was assessed by a CCK‑8 assay and cell migration and invasion were examined by a Transwell assay. The expression of miR‑767 was increased in NSCLC serum, tissues and cells compared with controls. The reduction of miR‑767 in NSCLC cells led to the inhibition of cell proliferation, migration and invasion. UTMD increased the transfection efficiency of the miR‑767 inhibitor in NSCLC cells, and UTMD‑mediated miR‑767 inhibition resulted in a more significant suppressive effect on tumor cell proliferation, migration and invasion. Taken together, the results indicated that miR‑767 expression is upregulated in both NSCLC clinical samples and cells. The downregulation of miR‑767 can inhibit tumor cell proliferation, migration and invasion, and these effects are further promoted by UTMD‑mediated miR‑767 inhibition, which indicated the potential of a UTMD‑mediated miR‑767 inhibition as a novel therapeutic strategy for NSCLC treatment.
