Expression analysis data of BCL11A and γ-globin genes in KU812 and KG-1 cell lines after CRISPR/Cas9-mediated BCL11A enhancer deletion.

The data presented in this article are related to the research article entitled as “Targeted deletion of the BCL11A gene by CRISPR-Cas9 system for fetal hemoglobin reactivation: A promising approach for gene therapy of beta-thalassemia disease " [1]. BCL11A is a master regulator of γ-globin gene silencing, and suppresses fetal hemoglobin expression by association with other γ-globin suppressors, and also interacts with human beta-globin locus control region as well as intergenic region between the Aγ and δ-globin genes to reconfigure beta-globin cluster. Thus, HbF reactivation has been proposed to be an approach for the treatment of β-thalassemia through knockout of BCL11A. Accordingly, an erythroid enhancer sequence was identified that, when inactivated, led to repression of BCL11A and induction of γ-globin in the erythroid lineage [2–7]. This article describes data that obtained from BCL11A gene enhancer modification in KU812 and KG-1 cell lines using the CRISPR-Cas9 genome editing system in order to reactivate γ-globin gene expression.
