DNA methylation under the microscope: Another step to better understanding of some leukemias
A decade of research at the International Institute of Molecular and Cell Biology has allowed scientists to better understand the mechanisms leading to DNA methylation. In some situations, undesirable methylation leads to myelodysplastic syndrome (MDS) and some leukemias (CMML, AML). Research on DNA methyltransferases was published in the prestigious journal Nucleic Acids Research.
