WebOur data showed that down-regulation of BCL11A induces γ-globin production in the K562 cell line and human erythrocytes from normal donors and β-TM donors, without altering erythroid maturation. This is the first report on γ-globin induction by down-regulation of BCL11A in human erythroblasts derived from β-TM. WebApr 10, 2006 · The developmental regulation of γ-globin gene expression has shaped research efforts to establish therapeutic modalities for …

WebApr 26, 2024 · Disruption of just the putative HbF silencer results in a mild increase in γ-globin expression, whereas deletion or inversion of a 13.6-kb region causes a robust reactivation of HbF synthesis in adult erythroblasts that is associated with epigenetic modifications and changes in chromatin contacts within the β-globin locus. WebInduction of fetal haemoglobin (HbF) is a promising therapeutic approach for the treatment of β-thalassaemia and sickle cell disease (SCD). Several pharmacological agents, such … tarife orange
Epigenetic activities in erythroid cell gene regulation
WebUsing gel-shift and chromatin immunoprecipitation (ChIP) assays, we have demonstrated that NF-Y and GATA-1 directly participate in transcriptional activation of the Gfi-1B gene … WebPharmacologic reinduction of the developmentally silenced fetal (gamma) globin genes has been achieved in hemoglobinopathy patients using short chain fatty acid derivatives, with therapeutic effects. However, higher-potency inducers than are available in currently identified short chain fatty acid derivatives are desirable for long-term use. WebMar 21, 2024 · The two types of gamma chains differ at residue 136 where glycine is found in the G-gamma product (HBG2) and alanine is found in the A-gamma product (HBG1). The former is predominant at birth. The order of the genes in the beta-globin cluster is: 5'-epsilon -- gamma-G -- gamma-A -- delta -- beta--3'.
