Certain individuals have long been regarded as particularly susceptible to developing behavioural and emotional problems when they experience negative environmental conditions, due to the fact that they carry so-called ‘vulnerability genes’.

Genomic Health, Inc. (Nasdaq: GHDX) today announced results from a study which summarized the gene signatures identified by the Oncotype DX(R) breast cancer test in a large number of male patients for whom the test was used to guide treatment with chemotherapy. The results, which will be presented in a poster presentation on Monday, June 1 (1:00 – 5:00 p.m.

By using ultrafast laser pulses to slice off pieces of chromosomes and observe how the chromosomes behave, biomedical engineers at the University of Michigan have gained pivotal insights into mitosis, the process of cell division. Their findings could help scientists better understand genetic diseases, aging and cancer.

The health of our skin – one of the body’s first lines of defense against illness and injury – depends upon the delicate balance between our own cells and the millions of bacteria and other one-celled microbes that live on its surface. To better understand this balance, National Institutes of Health researchers have set out to explore the skin’s microbiome, which is all of the DNA, or genomes, of all of the microbes that inhabit human skin.

VIB researchers linked to K.U.Leuven and Harvard University show that stretches of DNA previously believed to be useless ‘junk’ DNA play a vital role in the evolution of our genome. They found that unstable pieces of junk DNA help tuning gene activity and enable organisms to quickly adapt to changes in their environments. The results will be published in the reputed scientific ournal Science.

Two studies in the May 29th issue of Cell, a Cell Press publication, have taken advantage of new technological advances to search for and find previously unknown weaknesses in a hard to treat form of cancer. The discoveries lend new hope in the fight again tumors that are today considered “undruggable.” The tumors in question are driven by a particularly widespread alteration in the gene known as KRAS.

Mice carrying a “humanized version” of a gene believed to influence speech and language may not actually talk, but they nonetheless do have a lot to say about our evolutionary past, according to a report in the May 29th issue of the journal Cell, a Cell Press publication. “In the last decade or so, we’ve come to realize that the mouse is really similar to humans,” said Wolfgang Enard of the Max-Planck Institute for Evolutionary Anthropology.

As the best drugs become increasingly resistant to superbugs, McMaster University researchers have discovered a completely different way of looking for a new antibiotic. In a paper published May 29 in the journal Chemistry and Biology, with colleagues in Germany and Wilfrid Laurier University, they report on work with the bacteria Staphylococcus aureus bacteria, the leading cause of infections in hospitals and the second most common community-acquired infection.
