Individuals and populations differ in gene activity levels, not just genes

03-01-2007 · EurekAlert!

Much like how a person's genetic code differs from other individuals, the level at which those genes are activated in the body differs from one person to another, scientists have learned. And though some of those differences in gene activity are seen between different populations -- Asians versus Europeans, for instance -- more of those variations are due to individual-level factors, further obscuring the biological meaning of "race."

Inherited individual variations influence patterns of gene shuffling
01-31-2008 · EurekAlert!
The first large-scale, high-resolution study of human genetic recombination has found remarkably high levels of individual variation in genetic exchange, the process by which parents pass on a mosaic-like mixture of their genes. The high-resolution enables the researchers to map out the precise location of where these genetic exchanges occur and assess the differences in recombination rates between individuals.

The molecular signature of loneliness
09-12-2007 · EurekAlert!
People who experience chronically high levels of loneliness show gene-expression patterns that differ markedly from those of people who don't feel lonely, according to a new molecular analysis in the online open access journal Genome Biology. The findings suggest that feelings of social isolation are linked to alterations in immune system activity, which result in increased inflammatory signaling within the body.

Simulated populations used to probe gene mapping
03-23-2007 · EurekAlert!
Statisticians and genetic epidemiologists from Rice University and The University of Texas M. D. Anderson Cancer Center have used computer simulations to trace genetic changes over thousands of generations in a simulated population to find out whether the tools that statistical geneticists use to pinpoint disease genes are up to the task of identifying multiple genes that cause complex diseases like cancer. The study is published this week in PLoS Genetics.

Jefferson scientists show gene reverts cancer genes to normal, predicts breast cancer prognosis
10-31-2006 · EurekAlert!
Scientists have shown that the activity of a gene that commandeers other cancer-causing genes, returning them to normal, can predict the prognosis of an individual with breast cancer. They looked at cancer cells from more than 2,000 breast cancer patients and found that this commandeering or "organizing" ability is increasingly lost in cancer cells and associated with the progression of disease. The more the gene is expressed in breast cancer, the better the patient did.

Which genome variants matter?
02-08-2007 · EurekAlert!
Findings published in Science will accelerate the search for genes involved in human disease. This first genome-wide view shows that activity of more than 1000 genes is affected by sequence variation. This is an important step to understanding links between genes and disease for individuals, and across populations. By defining those genetic variants with a biological effect, the results will help prioritise regions of the genome that are investigated for association with disease.

University of Toronto finds humans and chimps differ at level of gene splicing
11-14-2007 · EurekAlert!
Researchers are closer to understanding why humans differ so greatly from chimpanzees in the way they look, behave, think and fight off disease, despite having genes that are nearly 99 percent identical.

Researchers discover gene mutation thought to control energy levels
09-18-2007 · EurekAlert!
This study focused on the gene for AMPK (adenosine monophosphate-activated protein kinase), which controls the amount of energy in our cells by becoming active when fuel stores start to deplete, such as during exercise. The mutation discovered in individuals from two unrelated families caused a doubling of AMPK activity in muscle during rest, mimicking a state of exercise. This significant discovery appears in the Sept. 19 issue of the online, open-access journal, PLoS ONE.

A molecular map for aging in mice
11-28-2007 · EurekAlert!
Researchers at the National Institute of Aging and Stanford University have used gene arrays to identify genes whose activity changes with age in 16 different mouse tissues. The study, published Nov. 30 in PLoS Genetics, uses a newly available database called AGEMAP to document the process of aging in mice at the molecular level. The work describes how aging affects different tissues in mice, and ultimately could help explain why lifespan is limited to just two years in mice.

Opening and closing the genome
02-22-2007 · EurekAlert!
A dynamic cast of gatekeeper enzymes controls access to the DNA for gene transcription, adding and removing particular molecules to open or close the genome as needed. Researchers have identified an important new player in this gene-control system, an enzyme responsible for removing certain molecules, or marks, involved in opening or closing chromatin, the material that makes up chromosomes. The activity of this enzyme is thought to be widespread, likely affecting many genes.

Researchers witness natural selection at work in dramatic comeback of male butterflies
07-12-2007 · EurekAlert!
When an invasive bacteria ravaged the male embryos of the Blue Moon butterfly, it left populations that were nearly entirely female. But the males made an extraordinary comeback, going from 1 percent to 39 percent of the population in less than a year. Researchers at UC Berkeley and elsewhere witnessed this resurgence, and credited it to the rise of a suppressor gene that stopped the male-killing bacteria in its tracks.
