Scientists Map First Complete Human Epigenome, The Driver Of Gene Expression

Scientists Map First Complete Human Epigenome, The Driver Of Gene Expression
Genetics News From Medical News Today
When scientists mapped the DNA sequence of 3 billion bases in the human genome they uncovered the master blueprint of what makes a human being; now a team in the US has produced a high resolution map of the first complete human epigenome, the driver of gene expression that regulates how all the options offered in the genome are put together to make the unique person that grows in a particular environment.

Cell's Powerhouses Dismantled: Complete Inventory Of All Proteins In Mitochondria

ScienceDaily (Oct. 15, 2009) — All of life is founded on the interactions of millions of proteins. These are the building blocks for cells and form the molecular mechanisms of life. The problem is that proteins are extremely difficult to study, particularly because there are so many of them and they appear in all sizes and weights. Now, Kris Gevaert from VIB/Ghent University and colleagues from the universities of Freiburg and Bochum have achieved a breakthrough in protein research. Using yeast, they have succeeded in making virtually the complete inventory of all the proteins in the mitochondria, the energy producers found in every cell.
