Comparative Studies Reveal Robust HbF Induction By Editing of HBG1/2 Promoters or BCL11A Erythroid-Enhancer in Human CD34+ Cells but That BCL11A Erythroid-Enhancer Editing Is Associated with Selective Reduction in Erythroid Lineage Reconstitution in a Xenotransplantation Model

Promoter Methylation and Gene Expression in Human CD34+ Stem Cells Derived Erythroid Lineage by MicroRNA
Background: Stem Cell differentiation is a process composed of vast variety of factors which are controlled by a network of certain mechanisms. This study aims to determine the possible role of DNA methylation, a potent regulator of VHL, ECAD and RUNX3 genes during Erythroid differentiation driven by miR-451. Materials and Methods: To determine the methylation status of promoters and the e...
متن کاملLong-Term Engraftment and Fetal Globin Induction upon BCL11A Gene Editing in Bone-Marrow-Derived CD34+ Hematopoietic Stem and Progenitor Cells
To develop an effective and sustainable cell therapy for sickle cell disease (SCD), we investigated the feasibility of targeted disruption of the BCL11A gene, either within exon 2 or at the GATAA motif in the intronic erythroid-specific enhancer, using zinc finger nucleases in human bone marrow (BM) CD34+ hematopoietic stem and progenitor cells (HSPCs). Both targeting strategies upregulated fet...

Background and aim: Induction of fetal hemoglobin (Hb-F) can improve the patients’ symptoms of haemoglobinopathies. Several factors can induce gamma globin gene expression and increased Hb-F levels in patients. In this study, the expression of genes is involved in regulation of gamma globin synthesis such as PIPKII-alpha BCL11a, and miR-30a during CD34+ hematopoietic stem cell differentiation i...
متن کاملMicroRNA-486-3p Regulates γ-Globin Expression in Human Erythroid Cells by Directly Modulating BCL11A
MicroRNAs (miRNAs) play key roles in modulating a variety of cellular processes through repression of mRNAs target. The functional relevance of microRNAs has been proven in normal and malignant hematopoiesis. While analyzing miRNAs expression profile in unilineage serum-free liquid suspension unilineage cultures of peripheral blood CD34(+) hematopoietic progenitor cells (HPCs) through the eryth...
