Abstract
- Hypermethylation of the promoter region is one of the major mechanism of tumor suppressor gene inactivation. In order to provide a research tool for the study on the function of MBD1 gene in DNA methylation and tumorigenesis, antisense MBD1 gene eukaryotic expression plasmid was constructed and transfected into human biliary tract carcinoma cell line QBC-939 to observe its effect on the expression of MBD1 mRNA and protein by using RT-PCR and FCM respectively. Following the transfection, the mRNA level of MBD1 gene decreased from 0. 912 +/- 0.022 to 0.215 +/- 0. 017, and the protein level of MBD1 gene also decreased from (80.19 +/- 5.05) % to (35.11 +/- 4.05) %. There were very significant differences in the expression both at the transcription and post-transcription levels of MBD1 gene between non-tranfection group and the antisense MBD1 gene eukaryotic expression plasmid transfection group (P0.01). It was suggested that transfection with the antisense MBD1 gene eukaryotic expression plasmid can significantly reduce the expression level of MBD1 gene in QBC-939, and this study may provide a valid tool for the investigation of the function of MBD1 gene and its role in biliary tract carcinoma.
