Hereditary persistence of fetal hemoglobin (HPFH) is a benign condition in which increased fetal hemoglobin (hemoglobin F, HbF) production continues well into adulthood, disregarding the normal shutoff point after which only adult-type hemoglobin should be produced.
WebDec 2, 2016 · Sickle Cell Disease (SCD) is caused by a point mutation in the beta- chain of hemoglobin, triggering a complex pathophysiology resulting in recurrent, painful vaso-occlusive events (VOCs) and chronic hemolytic anemia. Induction of fetal hemoglobin (HbF), is a well-established approach towards the treatment and potentially cure for SCD. WebObjective: In vivo, several drugs have been shown to increase fetal hemoglobin (HbF), including 5-azacytidine (AZA), sodium butyrate (SB), and hydroxyurea (HU). Studies in K562 cells suggest that cyclic guanosine monophosphate (cGMP) is required for HbF induction; however, the role of cyclic nucleotides in HbF induction in primary erythroid cultures has …
WebDec 10, 2024 · Introduction. Sickle cell disease (SCD) is a collection of disorders characterized by the inheritance of a single base substitution (replacement of hydrophilic glutamic acid by hydrophobic valine) in the first exon of the β-globin gene (HBB).
