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.
