The primary study about the relationship of FBN2 gene and lung cancer cell lines / 重庆医科大学学报

ABSTRACT

Objective:To study the gene expression and aberrant methylation of FBN2 on lung cancer cell lines.Methods:Three lung cancer cell lines HCC366,H1299 and H2195 were cultured.mRNA was analysed by RT-PCR and methylation status was also investigated by methylation specific PCR.The loss of FBN2 expression cell lines were treated with the demethylating agent,5-aza-2'-deoxycytid-ine(5-aza-cdR).Results:The expression of FBN2 was detected in NHBEC and H2195,whereas it was not detected in HCC366 and H1299 which showed aberrant methylation of FBN2.FBN2 expression was restored after treatment with 5-aza-cdR.Conclusion:Methylation and silencing of FBN2 in tumor cells may play an important role in carcinogenesis of lung cancer.
