| 520 | 3 | |a Background and objectives: Developing a methylation-specific dot blot assay (MSP-DB) to increase the sensitivity and specificity of simultaneous methylation analysis of multiple genes is the goal of the present study to evaluate the methylation status of GSTP1 and RASSF1A from prostate cancer in Vietnamese males. Methods: The methylation of GSTP1 and RASSF1A was investigated by using the MSP in 50 prostate cancer and 17 benign prostate hyperplasia specimens. The MSP-DB assay that uses a single or multiple probes specifically detected the methylation status of a particular gene or of the two genes GSTP1 and RASSF1A at the same time in a series of samples. The sensitivity and specificity of the MSP-DB were compared to those of the MSP. Results: The probes specifically hybridized with the methylated targets only in the MSP-DB, which allowed detecting GSTP1 and RASSF1A methylation in 23 of 50 and 14 of 50 patients with prostate cancer and in 2 of 17 and 4 of 17 patients with benign prostate hyperplasia. MSP-DB following the MSP assay improved the sensitivity of detection to more than 0.01% methylated status of a given high CpG-rich region. One methylated MSP product corresponding to the GSTP1, lack of methylated cytosine, was clearly detected on gel electrophoresis but barely visible on MSP-DB. Thus, the MSP-DB is suitable to eliminate the risk of false-positive results. Conclusion: The MSP-DB dispels the weakness of MSP and increases the sensitivity to simultaneous methylation analysis of multiple genes. The MSP-DB is advantageous for the promotion of DNA methylation markers in progressing quickly toward clinical application. | |
