| Research Abstract |
The purpose of this study is to specify the effect of de-methylating agents on myelodysplastic syndrome (MDS) patients. So far, we have constructed promoter methylomes from 4 MDS patients (2 with RCMD and 2 with RAEB-2), as well as that from two healthy donors (commercial products). Samples from the two different subtypes clustered together, and it seems likely that DNA methylation analysis could serve as a useful diagnostic. We found an enormous over-representation of transcription factors within sets of identified genes differentially methylated between the two tumor types. Most other genes identified could also be considered to have regulatory functions with many genes encoding proteins involved in signal transduction, as well as a number of microRNA genes. We also looked at biological process associated with these gene sets. For most analyses we found an even more enormous over-representation of genes associated with various developmental processes, with many genes involved in nervous system development.
