The National Institutes of Health (NIH) Common Fund's 4D Nucleome Program delivered new insights on genome organization on July 23 [1].
This research is critical because it examines how the dynamic, three-dimensional folding of chromatin—the "fourth dimension"—shapes gene regulation. Understanding this architecture allows scientists to better determine how cell identity is formed and how aging and disease processes occur.
The findings are highlighted in a special issue of the journals Science and Science Advances. These publications feature single-cell and multi-omic studies that explore the spatial organization of the genome and its impact on biological development.
This scientific milestone follows a decade of research [1]. The effort is led by a consortium of researchers, including Job Dekker, PhD, with significant research centers located at the University of California, San Diego.
To support these goals, the NIH awarded three grants [2]. These awards provided between $30 million [2] and $31.8 million [3] in funding over a five-year period [2, 3].
The program focuses on the complex ways the genome folds within the nucleus. By mapping these interactions, researchers aim to uncover the mechanisms that trigger specific genes to turn on or off, which can be disrupted in various diseases.
“The program focuses on the complex ways the genome folds within the nucleus.”
The transition from 3D genome mapping to 4D nucleome research represents a shift toward understanding the genome as a dynamic, changing structure rather than a static map. By integrating temporal data with spatial organization, scientists can potentially identify the exact moment a genetic fold contributes to a disease state, opening new avenues for precision medicine and targeted genomic therapies.
