In their study, they found that upon treatment, proteins involved in translation initiation and elongation were significantly down regulated, as well as down regulation of heterogeneous nuclear ribonucleoproteins and the protein phosphatase 2A (PP2A), suggesting that post‐transcriptional suppressive pathways are activated during ATRA‐induced growth inhibition and differentiation processes in APL.28 Liu et al. The gene discussed is PTPA; the disease is acute promyelocytic leukemia.
