PRDM2 and chronic myelogenous leukemia, BCR-ABL1 positive: Prior attempts to determine a set of genes regulated by PRDM2 include gene expression array analysis of chronic myeloid leukemia cells expressing exogenous PRDM2, revealing several genes involved in insulin-like growth factor signaling as targets [31], and expression analysis of livers from PRDM2 knockout mice identifying 97 putative PRDM2 target genes [32].
