Lysine-specific demethylase 1 is a therapeutic target for fetal hemoglobin induction.


ABSTRACT: Enhanced fetal ?-globin synthesis alleviates symptoms of ?-globinopathies such as sickle cell disease and ?-thalassemia, but current ?-globin-inducing drugs offer limited beneficial effects. We show here that lysine-specific demethylase 1 (LSD1) inhibition by RNAi in human erythroid cells or by the monoamine oxidase inhibitor tranylcypromine in human erythroid cells or ?-type globin-transgenic mice enhances ?-globin expression. LSD1 is thus a promising therapeutic target for ?-globin induction, and tranylcypromine may serve as a lead compound for the development of a new ?-globin inducer.

Enhanced fetal γ-globin synthesis alleviates symptoms of β-globinopathies such as sickle cell disease and β-thalassemia, but current γ-globin-inducing drugs offer limited beneficial effects. We show here that lysine-specific demethylase 1 (LSD1) inhibition by RNAi in human erythroid cells or by the monoamine oxidase inhibitor tranylcypromine in human erythroid cells or β-type globin-transgenic mice enhances γ-globin expression.
