JAZF1 and thalassemia: Knocking down the expression of ZNF802 by ZNF802sh-35 and ZNF802sh-71 in β0-thalassemia/HbE erythroid cells reactivated HbF to 26.9 ± 7.4% and 26.4 ± 8.8%, respectively, whereas the baseline HbF levels of shNTC varied between 12–23% with a mean of 18.5 ± 6.8%, (n = 9, Fig. 2E).
