Abstract: During the last few decades, foetal haemoglobin reactivation has been considered as a promising intervention to treat β-thalassaemia and sickle-cell anaemia. Variable foetal haemoglobin (Hb F, α 2γ2) production among individuals is under control of distinct chromosome regions, namely, the quantitative trait loci (QTL). One of the QTL affecting Hb F levels on chromosome 8q has never been explored. The zinc fingers and homeodomains 2 (ZHX2) transcription factor located at 8q position is remarkably down-regulated in hereditary persistence of foetal haemoglobin, indicating an inverse correlation between the γ-globin and ZHX2 expression. Here we studied the effect of ZHX2 over the γ-globin expression in K562 erythroleukaemic cell line by transient transfection with a ZHX2 expression plasmid. At 24 h after transfection, the relative expression of endogenous γ-globin mRNA had been reduced to 0.401 ± 0.08 as assessed by real-time PCR. Our finding suggests that the repressive effect on γ-globin probably results from the presence of ZHX2 and supports its possible involvement in the regulation of γ-globin expression.
