Abstract :

Methylation is a process of ?¢????turning off?¢??? the genes, which is implicated in the pathology of cancer and in many other disorders. The methylation-based biomarkers are highly promising candidates for both early diagnosis and treatment of many diseases. There are four primary fields of use for the in-vitro diagnostic biomarkers: 1. Diagnosis 2. Prognosis/Prediction 3. Prevention 4. Pharmacoepigenomics The methylation biomarkers have already been shown to fulfill the requirements of each of the above categories. Therefore vast majority of research in the field focuses currently on discovery and validation of methylation based biomarkers for clinical use. The initial steps of the identification/discovery procedure should normally employ two technologies: the technology allowing for genome wide screening for disease related methylation changes and the single PCR based methodology. The technologies allowing scanning for the genome wide methylation changes normally display high level of intra experimental data variation and therefore cannot be directly applied in diagnostic settings. Therefore the PCR based technologies has to be used to: firstly validate the genome wide screening findings and secondly to develop a test that can be applied in diagnostic settings. We have successfully combined state of the microarray technology: Roche/NimbleGene MicroArrays and the Methylation Sensitive High Resolution Melting (MS-HRM), for methylation biomarkers development and validation. The new workflow allowed us to discover and successfully perform clinical validation of 20 novel breast cancer methylation biomarkers. Overall, the technical specifications of our new workflow meet requirements for the complete platform for methylation biomarkers discovery, validation and diagnostic application.
