Further, to confirm the clinical significance of miR-150 and FOXO4 in NSCLC patients, we analyzed the transcriptional levels of miR-150 and FOXO4 in 16 cases of human non-neoplastic lung tissues and 36 cases of human NSCLC lung tissues including 19 cases of non-metastatic NSCLC tissues and 17 cases of metastatic NSCLC tissues by qRT-PCR assays. This evidence concerns the gene FOXO4 and non-small cell lung carcinoma.
