ZNF410 uniquely activates the NuRD component CHD4 to silence fetal hemoglobin expression [RNA-Seq]

Project description:Metazoan transcription factors typically regulate large numbers of genes. Here we identify via a CRISPR-Cas9 genetic screen ZNF410, a pentadactyl DNA binding protein that in human erythroid cells directly and measurably activates only one gene, the NuRD component CHD4. Specificity is conveyed by two highly evolutionarily conserved clusters of ZNF410 binding sites near the CHD4 gene with no counterparts elsewhere in the genome. Loss of ZNF410 in adult type human erythroid cell culture systems and xenotransplant settings diminishes CHD4 levels and derepresses the fetal hemoglobin genes. While previously known to be silenced by CHD4, the fetal globin genes are exposed here as among the most sensitive to reduced CHD4 levels. In vitro DNA binding assays and crystallographic studies reveal the ZNF410-DNA binding mode. ZNF410 is a remarkably selective transcriptional activator in erythroid cells whose perturbation might offer new therapeutic opportunities in the treatment of hemoglobinopathies.

ZNF410 Uniquely Activates the NuRD Component CHD4 to Silence Fetal Hemoglobin Expression.

Project description:Metazoan transcription factors typically regulate large numbers of genes. Here we identify via a CRISPR-Cas9 genetic screen ZNF410, a pentadactyl DNA-binding protein that in human erythroid cells directly activates only a single gene, the NuRD component CHD4. Specificity is conveyed by two highly evolutionarily conserved clusters of ZNF410 binding sites near the CHD4 gene with no counterparts elsewhere in the genome. Loss of ZNF410 in adult-type human erythroid cell culture systems and xenotransplantation settings diminishes CHD4 levels and derepresses the fetal hemoglobin genes.

Gene expression profiling of HUDEP-2 cells edited with either ZNF410 targeting or control sgRNA

Project description:RNA sequencing was performed of HUDEP-2 cells edited at either ZNF410 or AAVS1 (control locus) to measure gene expression changes due to loss of ZNF410 expression. CHD4 was the most significantly downregulated gene upon ZNF410 editing. We observed that ZNF410 binds to DNA upstream of the CHD4 gene. To test the requirement of ZNF410 binding for CHD4 expression we generated a HUDEP-2 clone in which this region of ZNF410 binding was deleted (CHD4 6.7 kb element deletion clone). We performed RNA-seq of CHD4 6.7 kb element deleted HUDEP-2 cells after either ZNF410 or AAVS1 (control locus) editing and only observed 2 differentially expressed genes after ZNF410 editing in CHD4 6.7 kb element deletion cells, consistent with our results that nearly all gene expression changes found after ZNF410 editing are due to changes in CHD4 expression.

NuRD subunit CHD4 regulates super-enhancer accessibility in Rhabdomyosarcoma and represents a general tumor dependency

Project description:ATP-dependent chromatin remodelers modulate gene expression by regulating genome accessibility and can contribute to tumorigenesis. In fusion-positive rhabdomyosarcoma (FP-RMS), we have previously identified the chromatin remodeler and NuRD subunit CHD4 as an essential gene for tumor survival. Here, we demonstrate that the FP-RMS vulnerability to CHD4 goes beyond its function as a NuRD member. Mechanistically, CHD4 interacts with BRD4 and co-localizes with the tumor driver and fusion protein PAX3-FOXO1 at super-enhancers where it generates a chromatin architecture permissive for the binding of the fusion protein. This allows the positioning of RNA polymerase 2 at promoters and the expression of the oncogenic program of PAX3-FOXO1. Additionally, analysis of genome-wide cancer dependency databases identifies CHD4 amongst the NuRD subunits as general novel cancer vulnerability. Our findings describe, for the first time, CHD4 as a regulator of super-enhancer-mediated gene expression and establish this chromatin remodeler as an unexpected broad tumor susceptibility.

CHD4 and the NuRD complex directly control cardiac sarcomere formation

Project description:Cardiac development relies on proper cardiomyocyte differentiation including expression and assembly of cell-type specific actomyosin subunits into a functional cardiac sarcomere. Control of this process involves not only promoting expression of cardiac sarcomere subunits but also repressing expression of non-cardiac myofibril paralogs. This level of transcriptional control requires broadly expressed multiprotein machines that modify and remodel the chromatin landscape to restrict transcription machinery access. Prominent among these is the Nucleosome Remodeling and Deacetylase (NuRD) complex, which includes the catalytic core subunit CHD4. Here, we demonstrate that direct CHD4-mediated repression of skeletal and smooth muscle myofibril isoforms is required for normal cardiac sarcomere formation, function, and embryonic survival early in gestation. Through transcriptomic and system genome-wide analyses of CHD4 localization, we identified novel CHD4 binding sites in smooth muscle myosin heavy chain, fast skeletal α-actin, and the fast skeletal troponin complex genes. We further demonstrate that in the absence of CHD4, cardiomyocytes in the developing heart form a hybrid muscle cell that contains cardiac, skeletal and smooth muscle myofibril components. These misexpressed paralogs intercalate into the nascent cardiac sarcomere to disrupt sarcomere formation and cause impaired cardiac function in utero. These results demonstrate the genomic and physiological requirements for CHD4 in mammalian cardiac development.
