CEBPD and neoplasm: Combined with the observations that CEBPD triggers growth arrest, participates in the bortezomib-induced cell death (Figures 1d and 2b) and activates miR-744, miR-3154 and miR-3162, we further provided a novel mechanism that miRNAs serve as tumor suppressors by eliciting DNA methylation on gDNA in leukemic cells.
