Chromosome 21-encoded miR-125b cooperates with GATA1s in trisomy 21-associated megakaryoblastic leukemia by targeting the megakaryocytic transcription factor ARID3A I

The purpose of this study was to decipher the molecular network underlying the synergy between the GATA1s mutation and loss of Arid3a. We used gene expression profiling (RNA-Seq) to evaluate gene expression changes upon gain and loss of Arid3a in the context of the Gata1s mutation We modulated levels of Arid3a in Gata1s-fetal liver cells
