An Epigenetics Gold Rush: New Controls for Gene Expression

February 22, 2017

(Nature) – Nine years later, such research has given birth to an ‘ome of its own, the epitranscriptome. He and others have shown that a methyl group attached to adenine, one of the four bases in RNA, has crucial roles in cell differentiation, and may contribute to cancer, obesity and more. In 2015, He’s lab and two other teams uncovered the same chemical mark on adenine bases in DNA (methyl marks had previously been found only on cytosine), suggesting that the epigenome may be even richer than previously imagined. Research has taken off.
