When a chemical tag makes the difference in cell fate and gene expression
(PHYSorg.com Biology)

Scientists at the Centre for Genomic Regulation in Barcelona, Spain, have uncovered the role of special chemical `tags` in controlling vital genes involved in early mammalian development, publishing their findings in the journal Nature Genetics on 17 September. The researchers studied the changes in epigenetics, genome architecture, accessibility and gene expression, and unraveled how cells can make quick cell fate decisions. The study has resulted in new understanding of cancer development and progression.
