[Press release] Researchers unravel health/disease map
Researchers affiliated with several organizations, including Simon Fraser University, have realized a major scientific achievement that will advance understanding of how the information in our cells is used and processed.
Steven Jones and Marco Marra, SFU Department of Molecular Biology and Biochemistry professor and adjunct professor, respectively, were among dozens of scientists on the pioneering project. Both SFU alumni, they are also with theCanada’s Michael Smith Genome Sciences Centre and BC Cancer Agency.
The scientists are globally celebrating their completion of 20 manuscripts that describe their generation and analysis of reference epigenome maps.
Epigenomes are chemical modifications of DNA and proteins that control the structure and activity of our genome. Ultimately, they cause our genome to stay healthy or develop diseases because they code for cellular properties that distinguish one cell type from another.
The journal Nature has issued a special publication to showcase the researchers’ collection, which contains molecular mark-up language for translating the epigenomes of 111 distinct human cell and tissue types.
“The DNA that makes up a human genome is essentially the same in every cell,” explains Jones, a co-author on the manuscript that integrates all 111 epigenomes into a single comparative analysis.
The project, called the National Institutes of Health (NIH) Roadmap Epigenomics Mapping Consortium, provides a core set of data, methodology and infrastructure for studying the epigenome’s role in human health and disease. The original goal was to map 25 normal reference epigenomes, but new technology allowed the team to produce 111 highly detailed maps on how the epigenome varies and operates in different settings.
