Gene expression profiling on heads of Drosophila chromodomain helicase DNA binding protein 1 (CHD1) deletion mutants

Project description:CHD1 is a conserved ATP-dependent chromatin remodeling factor with roles in transcriptional regulation and chromatin assembly. Here we show that deletion of Chd1 causes multiple behavioral and metabolic defects. In particular, it diminishes food-intake and results in shortened lifespan of mutant flies. These phenotypes can be rescued by brain-specific expression of Chd1 via the elav promoter. Consistently, neuron-specific expression of Chd1 rescues the wide-spread transcriptional dysregulation observed in the absence of CHD1.

Chromodomain Helicase DNA-binding 4 (CHD4) is required for B cell identity and lineage progression

Project description:B cell specification and identity are controlled by transcription factors and cytokine receptors that drive the expression of stage-specific transcriptomes during lineage progression. A key feature of these mechanisms is the repression of inappropriate transcription. Here, we utilized RNA-seq to demonstrate that chromodomain helicase DNA-binding protein 4 (CHD4), an ATPase/helicase subunit of Mi-2/NuRD chromatin remodeling complexes, is essential for B cell identity. In mice that lack CHD4 selectively in the B lineage, defects include developmental arrest at the early pro-B cell stage. While many pro-B-specific genes are expressed in the mutant cells, transcripts that are normally restricted to other tissues including pancreas and bone are expressed out of context. Moreover, CHD4-deficient pro-B cells do not proliferate in response to IL-7, exhibit greatly decreased utilization of distal VH segments and accumulate DNA damage. Together, our data confirm the importance of CHD4 and NuRD complexes for the generation of functional B cells.

The Chromatin Remodeler Chromodomain Helicase DNA Binding Protein 2 Promotes Colorectal Cancer Progression

Project description:Integrative analysis of colorectal cancer (CRC) whole genomes and matched transcriptomes revealed that somatic promoter mutations are associated with increased Chromodomain helicase DNA-binding protein 2 (CHD2) levels. In both primary and metastatic CRC patients, elevated CHD2 levels are associated with worse prognosis and overall survival. We find that CHD2 increases promoter-transcription start site-chromatin accessibility and transcriptional upregulation of multiple oncogenes. In vitro, elevated CHD2 promoted CRC cell proliferation, migration and growth. In orthotopic xenografts, CHD2 promoted higher tumor burden and abdominal metastases, most prominently to the liver. FTD/TPI is an FDA approved chemotherapy for advanced chemo-refractory CRC. In orthotopic CRC models, FTD/TPI was highly effective in reducing metastases and prolonging survival for CHD2 high expressing CRCs. Thus, high CHD2 expression may be a potential CRC chemopredictive biomarker for FTD/TPI. Overall, these results provide new insights into the role of non-coding mutations and CHD2 levels to promote CRC growth and metastasis.

Deletion of nucleoporin Seh1 impaired neurogenesis through transcriptional regulation (ChIP-Seq)

Project description:Nucleoporin Seh1 and chromodomain helicase DNA binding protein 4 have been involved in gene regulation. To dissect direct regulated genes, we performed chromatin immunoprecipitation DNA-sequencing (ChIP-seq) for nucleoporin Seh1 or chromodomain helicase DNA binding protein 4 in neural stem cells.
