Core Insights - The publication of a detailed map of human chromosomes by the journal Nature provides a foundational resource for understanding the relationship between the physical structure of human DNA and biological expression [1][2] - The 3D organization of human chromosomes plays a crucial role in coordinating genetic material to regulate biological responses, with chromatin being a complex formed by DNA winding around histones [1][2] - The 4D Nucleomics initiative, launched by the National Institutes of Health in 2015, aims to develop technologies to study the spatial and temporal structure and function of nuclear organization [1][2] Group 1 - The research team cataloged over 140,000 chromatin loops for two cell types: human embryonic stem cells and fibroblasts, generating a nuclear environment model for individual genes [1][2] - The study revealed fundamental physical mechanisms of folded chromatin, such as extrusion and phase separation, which shape the complex 3D structure of gene groups [2] - Future research is needed to explore how these observed structures relate to individual gene functions and whether these findings can be applied to combat genetic diseases [2] Group 2 - The breakthrough results of the 4D Nucleomics initiative provide a new perspective on understanding genetic diseases, suggesting that many conditions may stem from abnormalities in chromatin 3D structure rather than solely from gene sequence mutations [3] - The established technological platform and datasets from this research will serve as a foundational resource for the life sciences field, aiding in the goal of "on-demand regulation of gene expression" [3] - This research could ultimately advance treatments for major diseases such as cancer and developmental disorders [3]
