Relationship between the expression of miR-92a in NSCLC tissues and clinical pathological parameters. The expression of miR-92a in the NSCLC tissues and tissues adjacent to the cancer tissues of the patients was measured by RT-PCR. The expression of miR-92a was expressed as mean ± standard deviation.
