PIXABAY, PUBLICDOMAINPICTURESMembers of the Roadmap Epigenome Consortium this week (February 18) published their analysis of 111 human epigenomes in Nature. Their publication was accompanied by a slew of other epigenome analyses, including those related to cancer and Alzheimer’s disease.

These achievements in epigenome mapping are “definitely a milestone,” said Kristian Helin of the University of Copenhagen who was not involved in the research. “It should mostly be credited for the enormous amount of work . . . that hopefully will serve as a very good guide for epigenome studies in the future.”

“At times, we need a control or reference, a baseline, and now we can just go here and download this data, and use that as a baseline for our experiments, and that’s important,” added Manel Esteller of the Bellvitge Biomedical Research Institute in Spain who was not involved in the study.
