Bradbury et al. performed a study characterizing the expression of all 18 histone deacetylases in AML blasts compared to peripheral blood mononuclear cells (PBMC) as well as CD34+ progenitors derived from the umbilical cord or granulocyte colony-stimulating factor (G-CSF)-stimulated healthy donors. This evidence concerns the gene CSF3 and acute myeloid leukemia.
