## Abstract

Abstract
Hemoglobinopathies, such as sickle cell disease (SCD) and thalassemia, are among the greatest public health
concerns in the world. Although new therapeutic modalities, such as gene therapy, are currently being tested,
there is a pressing need for pharmacologic approaches to treat general patient populations. Our long-term goal
is to develop a compound(s) that induces fetal-type globin (HbF) production by targeting the transcriptional
complex regulating globin switching. The objective of this application is to determine molecular mechanisms
underlying the LRF-NuRD-mediated γ-globin silencing and identify a mean(s) to target them. Our central
hypothesis is that the LRF-containing NuRD complex is a potential target for HbF reactivation therapy. The
rationale for the proposed research is that understanding the LRF/NuRD-mediated globin regulation will
provide greater understanding of the transcriptional complex regulating γ-globin repression and facilitate
development of novel therapeutic strategies for HbF induction therapy. Guided by strong preliminary data, we
expect to achieve our objective by pursuing the three specific aims: 1) to determine the molecular basis for γ-
globin reactivation in the absence of the LRF/NuRD; 2) to identify a domain(s) of CHD3/4 necessary for γ-
globin silencing; and 3) to determine functional significance of LRF/CHD3 interaction in controlling γ-globin
silencing. In Aim1, we will employ ChIP-seq and ATAC-seq foot-printing to determine how the NuRD-
associated pathways silences γ-globin expression in adult erythroid cells and how γ-globin is induced upon
LRF depletion. In Aim2, we will identify a minimal domain(s) of CHD3/4 responsible for γ-globin silencing. To
do so, we will perform a functional domain mapping using CRISPR-Cas9 gene mutagenesis. In Aim3, we will
determine functional significance of the LRF/CHD3 interaction in controlling γ-globin silencing. Our published
work and preliminary data strongly suggest that the NuRD-associated pathways, in which LRF and BCL11A
are involved, represent the near entirety of the “globin-switch”. We expect that the combined approaches
proposed here will elucidate the role of LRF and the NuRD complex in γ-globin silencing and facilitate
development of novel strategies for HbF reactivation therapy for hemoglobinopathies.
