Objective:
To investigate the expression and evaluate the clinical significance of long non-coding RNA, LINC01124, in non-small cell lung cancer (NSCLC) and to study its influence in this tumor.
Methods:
Hundred specimens of NSCLC tissues and normal lung tissues after surgery were collected. The qRT-PCR for LINC01124 expression was performed on cancerous and normal lung tissues. The correlations between the expression of LINC01124 and pathological characteristics were analyzed. PcDNA-LINC01124 was transfected to upregulate LINC01124 expression in NSCLC cells, and the transfection efficiency was evaluated by the qRT-PCR. CCK8 assay, wound-healing assay, and the Transwell assay were performed to evaluate the effect of ectopic LINC01124 expression on proliferation, migration, and invasive of NSCLC cells.
Results:
The expression level of LINC01124 was downregulated in tumor tissues when compared with the paired normal lung tissues (P<0.05). The expression of LINC01124 was associated with patients' age and distant metastasis (P<0.05). Enforced expression of LINC01124 significantly inhibited the proliferation, migration, and invasive ability of NSCLC cells.
Conclusion:
The expression of LINC01124 was decreased in patients with NSCLC of older age and with those having distant metastasis. LINC01124 may inhibit cell proliferation, migration, and invasive ability.
