We have assembled a team of investigators, staff scientists, and developers with a strong track record in analysis of chromatin interaction data, image processing, data visualization, integrative analysis of genomic and epigenomic data, data portal development, large-scale computing, and development of secure and \ufb02exible cloud technologies. In the \ufb01rst phase of the 4DN Project, we have developed the 4DN Data Portal as a central resource with tools for data submission, curation, analysis and quality control, visualization, exploration, and download. The portal provides an easy-to-navigate interface for accessing raw and intermediate data \ufb01les, allows for programmatic access via APIs, and incorporates novel analysis and visualization tools developed by DCIC as well as other Network members. In the second phase of the 4DN Project, we will continue to support the research activities by the 4DN Network, and to lead the creation of a well curated 4DN data resource for the scienti\ufb01c community. At the same time, we propose to enhance the utility of the 4DN Scienti\ufb01c Data and the Data Portal in multiple ways: i. We will create a platform to integrate imaging and sequencing data and support the creating of reference nuclear maps in a common coordinate system; ii. We will provide support for 4DN Projects on Human Health and Disease with customized ontology applications and protected data management; iii. We will develop new cloud platform capabilities to bring user analyses to the 4DN Data Portal, and apply cost-ef\ufb01ciency improvements to support increasing data volumes; iv. We will perform regular outreach activities to raise awareness about the data and tools generated by the Network and DCIC. Overall, we will ensure that the data generated in 4DN will have maximal impact for the scienti\ufb01c community.", "@id": "/awards/2U01CA200059-06/", "uuid": "71171a4e-dca1-44cb-8375-fafd896c6923", "name": "2U01CA200059-06", "@type": ["Award", "Item"], "project": "4DN", "display_title": "4D NUCLEOME NETWORK DATA COORDINATION AND INTEGRATION CENTER - PHASE II", "status": "current", "center_title": "DCIC - Park", "pi": {"error": "no view permissions"}, "principals_allowed": {"view": ["system.Everyone"], "edit": ["group.admin"]}}, "title": "Cell type-specific 3D-genome organization and transcription regulation in the  brain.", "status": "current", "authors": ["Liu S", "Wang CY", "Zheng P", "Jia BB", "Zemke NR", "Ren P", "Park HL", "Ren B", "Zhuang X"], "journal": "Science advances", "abstract": "3D organization of the genome plays a critical role in regulating gene  expression. How 3D-genome organization differs among different cell types and  relates to cell type-dependent transcriptional regulation remains unclear. Here,  we used genome-scale DNA and RNA imaging to investigate 3D-genome organization in  transcriptionally distinct cell types in the mouse cerebral cortex. We uncovered  a wide spectrum of differences in the nuclear architecture and 3D-genome  organization among different cell types, ranging from the size of the cell  nucleus to higher-order chromosome structures and radial positioning of chromatin  loci within the nucleus. These cell type-dependent variations in nuclear  architecture and chromatin organization exhibit strong correlations with both the  total transcriptional activity of the cell and transcriptional regulation of cell  type-specific marker genes. Moreover, we found that the methylated DNA binding  protein MeCP2 promotes active-inactive chromatin segregation and regulates  transcription in a nuclear radial position-dependent manner that is highly  correlated with its function in modulating active-inactive chromatin  compartmentalization.", "date_created": "2025-08-12T16:42:53.242570+00:00", "submitted_by": {"error": "no view permissions"}, "last_modified": {"modified_by": {"error": "no view permissions"}, "date_modified": "2025-08-12T16:42:54.472393+00:00"}, "date_published": "2025-02-28", "public_release": "2025-08-12", "schema_version": "2", "project_release": "2025-08-12", "exp_sets_prod_in_pub": [{"@type": ["ExperimentSetReplicate", "ExperimentSet", "Item"], "experimentset_type": "replicate", "uuid": "eeec002c-fbeb-4d00-98be-44988bc722ab", "accession": "4DNESPE924IP", "status": "released", "@id": "/experiment-set-replicates/4DNESPE924IP/", "display_title": "4DNESPE924IP", "principals_allowed": {"view": ["system.Everyone"], "edit": ["group.admin"]}, "experiments_in_set": [{"display_title": "multiplexed FISH on primary motor cortex -
