ABSTRACT
BACKGROUND:
This study was conducted to investigate the effect of P14 promoter aberrant methylation on the biological function of human lung adenocarcinoma cells.METHODS:
We used nested methylation-specific PCR (NMSP) to detect the methylation status of the p14ARF promoter region in SPCA1 and BEAS2B cell lines. The experimental groups were treated with 5-aza-2'-deoxycytidine (5-Aza). Quantitative real-time PCR, Western blot, flow cytometry, and Cell Counting Kit 8 were used to detect the expression of p14ARF messenger RNA and protein in each group, apoptosis, and cell proliferation inhibition, respectively.RESULTS:
NMSP detected that the p14 promoter region of SPCA1 cells has abnormal methylation status. After treatment with 5-Aza, the expression of p14ARF messenger RNA and protein in SPCA1 cells (P < 0.05) and the inhibition rate of cell proliferation (P < 0.05) were significantly increased, while the apoptosis rate was markedly increased (P < 0.05). However, no differences were observed in BEAS2B cells (P > 0.05).CONCLUSION:
Abnormal methylation of the p14ARF promoter region plays an important role in the development of lung cancer cells. Our results suggest the use of P14 promoter aberrant methylation as a therapeutic target for drug research or to improve the sensitivity of other drugs.Palavras-chave
