In a new study, researchers at the Swedish medical university Karolinska Institutet have identified epigenetic changes — known as DNA methylation — in the blood of patients with schizophrenia. The researchers were also able to detect differences depending on how old the patients were when they developed the disease and whether they had been treated with various drugs. In the future this new knowledge may be used to develop a simple test to diagnose patients with schizophrenia....

Researchers at the University of California, Davis, have figured out how the human body keeps essential genes switched “on” and silences the vast stretches of genetic repeats and “junk” DNA. Frédéric Chédin, associate professor in the Department of Molecular and Cellular Biology, describes the research in a paper published today (March 1) in the journal Molecular Cell. The work could lead to treatments for lupus and other...

The domestication of chickens has given rise to rapid and extensive changes in genome function. A research team at Linköping University in Sweden has established that the changes are heritable, although they do not affect the DNA structure. Humans kept Red Junglefowl as livestock about 8000 years ago. Evolutionarily speaking, the sudden emergence of an enormous variety of domestic fowl of different colours, shapes and sizes has occurred in record time. The traditional...

Writing in the February 17, 2012 issue of the journal Cell, researchers at the Ludwig Institute for Cancer Research, the University of California, San Diego School of Medicine and the Toronto Western Research Institute peel away some of the enduring mystery of how zygotes or fertilized eggs determine which copies of parental genes will be used or ignored. In developing humans and other mammals, not all genes are created equal — or equally used. The expression of certain genes, known...

Mental illness suspect genes are among the most environmentally responsive For the first time, scientists have tracked the activity, across the lifespan, of an environmentally responsive regulatory mechanism that turns genes on and off in the brain's executive hub. Among key findings of the study by National Institutes of Health scientists: genes implicated in schizophrenia and autism turn out to be members of a select club of genes in which regulatory activity peaks during an...

Genome Research (www.genome.org) publishes online and in print today a special issue entitled, "Cancer Genomics," highlighting insights gained form cutting-edge genomic and epigenomic analyses of cancer. Included in this special issue are novel biological insights gained from genomic analyses of pancreatic cancer, ovarian cancer, and melanoma, including, functional genomic analyses of breast cancer genes, large scale colorectal and breast cancer epigenomics, advances in methodology...

Researchers at UC Santa Barbara have discovered a molecular pathway that may explain how a particularly deadly form of cancer develops. The discovery may lead to new cancer therapies that reprogram cells instead of killing them. The findings are published in a recent paper in the Journal of Biological Chemistry. The UCSB research team described how a certain mutation in DNA disrupts cellular function in patients with acute myeloid leukemia (AML). The researchers were prompted to study this...

UT MD Anderson researchers expose molecular connection between inflammation, methylation Chronic inflammation combines with DNA methylation, a process that shuts down cancer-fighting genes, to promote development of colorectal cancer, scientists at The University of Texas MD Anderson Cancer Center report today in the advance online publication of the journal Nature Medicine. The team's connection of these two separate influences eventually may lead to better combination therapies for...
