Editing the core region in HPFH deletions alters fetal and adult globin expression for treatment of ß-hemoglobinopathies  [4C]
We have identified putative repressor region (PRR) to exon-1 of ß-globin (ßE1) in the ß-globin cluster as a core region in alll the HPFH deletions that activates fetal hemoglobin and silences adult hemoglobin. To test the impact of PRR-ßE1 gene editing in ß-globin cluster configuration, we employed  Circular chromosome conformation capture (4C) analysis to assess the LCR interaction to the gamma-globin promoter. Using HBG2 promoter as viewpoint,4C analysis showed an increased interaction of HBG promoter to the hypersensitive (HS) sites of the LCR in HUDEP-2 clones harbouring PRR-ßE1 biallelic deletions compared to control HUDEP-2 cells.
