MIR29B mediates epigenetic mechanisms of HBG gene activation.

ABSTRACT: Sickle cell disease (SCD) affects over 2 million people worldwide with high morbidity and mortality in underdeveloped countries. Therapeutic interventions aimed at reactivating fetal haemoglobin (HbF) is an effective approach for improving survival and ameliorating the clinical severity of SCD. A class of agents that inhibit DNA methyltransferase (DNMT) activity show promise as HbF inducers because off-target effects are not observed at low concentrations. However, these compounds are rapidly degraded by cytidine deaminase when taken by oral administration, creating a critical barrier to clinical development for SCD. We previously demonstrated that microRNA29B (MIR29B) inhibits de novo DNMT synthesis, therefore, the goal of our study was to determine if MIR29 mediates HbF induction. Overex
