Objective:To detect the effects and mechanism of 5-aza-2’-deoxycytidine on the expression of PTEN in adenoid cystic carcinoma.Methods:The expression of mRNA and protein of PTEN were analyzed by RT-PCR and western blot after treatment with methyltransferase inhibitor 5-aza-2’-deoxycytidine(5-Aza-dc).Results:After the treatment with methyltransferase inhibitor 5-aza-2’-deoxycytidine(5-Aza-dc)
the levels of mRNA and protein of PTEN in adenoid cystic carcinoma cells were increased dramatically(P<0.05)
and the levels of PTEN mRNA and protein changes were consistent.Conclusion:The hypermethylation of CpG island in promoter of PTEN is probably responsible for low PTEN expression in adenoid cystic carcinoma cells.
