Since HU did not increase luciferase activity from our constructs, results of these experiments were not informative.Key words عglobin induction pathway.We also investigated role of a G- ع /expression through a Creb1/ATF-2 binding site present exclusively in the promoter of G We have used western blot to investigate levels of CREB1 in knockdown cells.Western blot analyses demonstrated that CREB1 becomes phosphorylated in a dose-dependent manner after HU treatment of K562 cells. These results suggest that Creb1 is required for the HU عvia p38 MAPK phosphorylation. It has been shown that SB induces G عinduction in erythroid cells. In addition, both HU and SB activate G (ع(and not A عglobin induction isnot completely understood. Similarities between the HU and sodium butyrate(SB) pathways suggested CREB1 as a potential candidate. The aim of this study was to investigate the possible role of CREB1 in this pathway. First, both HU and SB lead to G-ع globin transcription and fetal hemoglobin (HbF) production in erythroid cells. However its signaling pathway leading to-ع thalassemia treatment.
