Today, an article published in Cell by Manel Esteller, director of the Epigenetics and Cancer Biology Program of the Bellvitge Biomedical Research Institute (IDIBELL), ICREA researcher and Professor of Genetics at the University of Barcelona, describes the possible existence of a sixth DNA base, the methyl - adenine (mA), which also help determine the epigenome and would therefore be key in the life of the cells.

«We note that there are two subgroups of breast tumors by epigenome: one which we have called Epi - Basal, characterized by loss of epigenetic marks causing breakage of chromosomes and the other that we have called Epi - Luminal B, that presents epigenetic inactivation of genes that should protect us from cancer and these altered cells can no longer do it.»
The authors first generated a common set of chromatin states across 127 epigenomes (111 of their own, and 16 more borrowed from ENCODE), all of which had been profiled for five core histone marks.
A subset of the epigenomes were therefore profiled for H3K27ac and H3K9ac, which mark increased activation of enhancer and promoter regions.

As an extension to genetics projects, we now aim to identify and characterize in greater depth genes implicated in hematopoietic development in the EU FP7 - funded BLUEPRINT project, which will generate reference genomes and epigenomes of at least 100 specific blood cell types.
The current report, which appears in the May 4, 2012 issue of the journal Cell Stem Cell, shows that these cells can also change their epigenomes, the patterns of DNA modifications that regulate the activity of specific genes — sometimes radically.
Mapping the epigenome will allow Vijay and his team to zoom in on those genes with the greatest likelihood to contribute to disease, and the cell types in which they act, and therefore will help identify novel therapeutic targets.
Moreover, the epigenome creates a pattern of modifications that help determine which genes are turned on and off.
The epigenome — defined by an ever - expanding list of modifications to DNA and the proteins that interact with it — determines which genes are dialed up or down and gives each cell type its unique personality.
