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...

In the bone marrow, blood-forming (hematopoietic) stem cells become one of the myriad kinds of blood cells in the body or they can self-renew, maintaining that pool. However, the lack or mutation of a gene for an enzyme called Dnmt3a (DNA methyltransferase 3a) results in an abundance of stem cells and a lack of blood cells, said a consortium of researchers led by those at in the Stem Cells and Regenerative Medicine Center at Baylor College of Medicine in a report online in the journal...

A University of Cambridge study, which set out to investigate DNA methylation in the human heart and the 'missing link' between our lifestyle and our health, has now mapped the link in detail across the entire human genome. The new data collected greatly benefits a field that is still in its scientific infancy and is a significant leap ahead of where the researchers were, even 18 months ago. Researcher Roger Foo explains: "By going wider and scanning the genome in greater detail this...

Smoking during pregnancy profoundly changes both DNA and the expression of placental genes, a possible factor in physical changes that can last a lifetime, said researchers from Baylor College of Medicine in a report in the current edition of the journal Epigenetics. In a study that correlated changes in DNA methylation (a chemical change that affects the level of gene expression) to changes in gene expression across the genome of the placenta (the small ovoid organ that nourishes the...

COMBINATION 'EPIGENETIC' THERAPY MAY RESTORE ANTI-CANCER GENE ACTIVITY IN LATE-STAGE LUNG CANCER PATIENTS Small clinical trial shows promising positive effects A new type of therapy aimed at reversing the gene-silencing that promotes cancer-cell growth has shown promising results in a small clinical trial conducted by researchers at the Johns Hopkins Kimmel Cancer Center.  Forty-five late-stage lung cancer patients who received a two-drug combination designed to restore anti-cancer...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
