Abstract
Objective To observe the expression of miRNA-204 in the lung tissue of non-small cell lung cancer (NSCLC) patients and its effect on lung cancer cell proliferation and apoptosis. Methods qRT-PCR was used to detect the expression of miRNA-204 in the lung cancer and peri-cancerous tissues. After A-549 cells were interfered with miRNA-204 mimics, the cell proliferation was observed using CCK-8, cell apoptosis was observed by flow cytometry, and the mRNA and protein levels of Bcl-2 were detected by qRT-PCR and Western blot respectively. Results The expression of miRNA-204 in the NSCLC tissues was significantly lower than that in the peri-cancerous tissues (P < 0.05). And the low-expression of miRNA-204 in the NSCLC tissues was associated with tumor size and lymph node metastasis (P < 0.05). After interference of miRNA-204 mimics in the A-549 cells, the cell proliferation was reduced and the cell apoptosis was increased, and the mRNA and protein levels of Bcl-2 were decreased (P < 0.05). Conclusions The expression of miRNA-204 in the NSCLC tissues is decreased and related to the malignant clinicopathological features of lung cancer. miRNA-204 may affect the proliferation and apoptosis of non-small cell lung cancer cells by regulating Bcl-2 expression.关键词
