Gfi1b and gamma globin induction

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.
