Scientists call for unified standards in 3D genome and epigenetic data

News from the CRG

Studying the three-dimensional structure of DNA and its dynamics is revealing a lot of information about gene expression, expanding our knowledge of how cells, tissues and organs actually work in health and disease. Properly producing and managing this large amount of data is both challenging and necessary for the progress of this field. In a perspective paper published in Nature Genetics, top researchers call for unified standards and suggest guidelines in this emerging and promising research area.

“We know that genome folding and its dynamics modulates gene expression and new technologies allow us to build 3D models to study these changes, which is currently shaking up genome research and boosting our understanding of the cell nucleus complexity,” explains Marc A. Marti-Renom, ICREA research professor at the Centro Nacional de Análisis Genómico of the Centre for Genomic Regulation (CNAG-CRG) in Barcelona, Spain. “This is an absolutely promising field and we would like to call for standards since the rapid development of methods and the increasing complexity of data pose many challenges that must be addressed now,” he states.

In a perspective article published in the current issue of Nature Genetics, top leading scientists in the field of dynamics and structural genomics have called for standards in 3D genome and epigenetic data. They describe the main challenges in this field and provide guidelines to think about strategies for shared standardized validation of 4D nucleome data sets and models.
