Scientists take early steps toward mapping epigenetic variability
Brown University scientists have taken the first steps toward mapping epigenetic variability in cells and tissues. Mapping the human epigenome, similar to the human genome project in the 1990s, could someday ...

A foot in the door to genetic information
In the cell nucleus, DNA wraps around what are called histone proteins, forming regularly spaced spherical bodies called nucleosomes. Thus, large portions of the genetic material are inaccessible to the gene reading machinery. ...

Epigenetic changes don't last
Jean-Baptiste Lamarck would have been delighted: geneticists no longer dismiss out of hand his belief that acquired traits can be passed on to offspring. When Darwin published his book on evolution, Lamarck's ...

Epigenetic 'memory' key to nature versus nurture
Researchers at the John Innes Centre have made a discovery, reported this evening (July 24) in Nature, that explains how an organism can create a biological memory of some variable condition, such as quality of nutrition or tem ...

Cell reprogramming leaves a 'footprint' behind
Reprogramming adult cells to recapture their youthful "can-do-it-all" attitude appears to leave an indelible mark, found researchers at the Salk Institute for Biological Studies. When the team, led by Joseph ...

You are what your father ate: Paternal diet affects lipid metabolizing genes in offspring
Scientists at the University of Massachusetts Medical School and the University of Texas at Austin have uncovered evidence that environmental influences experienced by a father can be passed down to the next generation, "reprogramming" ...

Rett syndrome mobilizes jumping genes in the brain
With few exceptions, jumping genes-restless bits of DNA that can move freely about the genome-are forced to stay put. In patients with Rett syndrome, however, a mutation in the MeCP2 gene mobilizes so-called ...

Scientists find genes related to body mass
Johns Hopkins scientists who specialize in unconventional hunts for genetic information outside nuclear DNA sequences have bagged a weighty quarry — 13 genes linked to human body mass. The experiments screened the so-called ...

Stem cell first: Creating induced pluripotent stem cells
In a world first, Australian researchers have created induced pluripotent stem (iPS) cells from human skin without the use of viruses or genetic manipulation, an important step toward their eventual use in treating human ...

Slackers and superstars of the microbial workplace
Drug companies often use yeast to manufacture drugs, especially proteins such as antibodies and enzymes. It has been assumed that a batch of genetically identical yeast will secrete such drugs at uniform rates, ...

Scientists suggest certain genes boost chances for distributing variety of traits, drive evolution
Genes that don't themselves directly affect the inherited characteristics of an organism but leave them increasingly open to variation may be a significant driving force of evolution, say two Johns Hopkins scientists.
