WebSickle-cell disease (SCD) is a debilitating hematological disorder with very few approved treatment options. Therapeutic reactivation of fetal hemoglobin (HbF) is one of the most pursued methods for ameliorating the systemic manifestations of SCD. Despite this, very few pharmacological agents have advanced to clinical trials or marketing for use. In this … WebUsing this CRISPR screening approach we discovered a new zinc finger transcription factor, ZNF410, that is potentially targetable via a PROTAC that silences fetal hemoglobin transcription via a single target gene, the NuRD subunit CHD4 (Lan, Molecular Cell, 2024).
WebJul 7, 2011 · Fetal hemoglobin (HbF) is the major genetic modulator of the hematologic and clinical features of sickle cell disease, an effect mediated by its exclusion from the sickle hemoglobin polymer. Fetal hemoglobin genes are genetically regulated, and the level of HbF and its distribution among sickle erythrocytes is highly variable.
