Scientists gain new insights into the genetic susceptibility of multiple sclerosis

Australian and New Zealand researchers have accelerated research into Multiple Sclerosis by discovering two new locations of genes which will help to unravel the causes of MS and other autoimmune disease.

Gene evolution process discovered

One of the mechanisms governing how our physical features and behavioural traits have evolved over centuries has been discovered by researchers at the University of Leeds.

Don't stress when the going gets tough - you'll go gray!

A study by Japanese researchers has revealed that a certain kind of stress damages the hair - they say "genotoxic stress" damages DNA by depleting the melanocyte stem cells (MSCs) within hair follicles that are responsible for making the pigment-producing cells.

Waste disposal protein key to cancer tumor suppression in autophagy

"Taking out the trash" takes on a whole new meaning, as investigators at The Cancer Institute of New Jersey (CINJ) and Rutgers, The State University of New Jersey, have discovered that a waste disposal protein is the key to cancer tumor suppression in a process known as autophagy. CINJ is a Center of Excellence of UMDNJ-Robert Wood Johnson Medical School.

Genotoxic stress makes your hair go gray

Those pesky graying hairs that tend to crop up with age really are signs of stress, reveals a new report in the June 12 issue of Cell, a Cell Press publication.

Dangerous liaisons: bacterial 'sex' causes antibiotic resistance

Some disease-causing bacteria are becoming resistant to antibiotics because they have peculiar sex lives, say researchers publishing new results today in the journal Science.

The 'hijacking mechanism' of HIV-1 pinpointed

Researchers at McGill University and the affiliated Lady Davis Institute for Medical Research at Montreal's Jewish General Hospital - along with colleagues at the University of Manitoba and the University of British Columbia - may have found a chink in the armour of the human immunodeficiency virus type 1 (HIV-1), the microorganism which causes AIDS. They have pinpointed the key cellular machinery co-opted by HIV-1 to hijack the human cell for its own benefit.

Gene activity reveals dynamic stroma microenvironment in prostate cancer

As stroma - the supportive framework of the prostate gland - react to prostate cancer, changes in the expression of genes occur that induce the formation of new structures such as blood vessels, nerves and parts of nerves, said researchers at Baylor College of Medicine in a report that appears in the current issue of the journal Clinical Cancer Research.

Research identifies 3D structure of key nuclear pore building block

The genome of complex organisms is stashed away inside each cell's nucleus, a little like a sovereign shielded from the threatening world outside.

New research looks at the role of geography in human adaptation

New research indicates that natural selection may shape the human genome much more slowly than previously thought. Other factors -- the movements of humans within and among continents, the expansions and contractions of populations, and the vagaries of genetic chance - have heavily influenced the distribution of genetic variations in populations around the world.

Greater oversight needed in sharing of genetic information online

With just $399 and a bit of saliva in a cup, consumers can learn about their genetic risk for diseases from breast cancer to diabetes. Now, thanks to social networking sites set up by personal genomics companies, they can also share that information with family, friends and even strangers on the Internet.

Discovery of new genetic immune disorder in children

Your immune system plays an important function in your health - it protects you against viruses, bacteria, and other toxins that can cause disease. In autoinflammatory diseases, however, the immune system goes awry, causing unprovoked and dangerous inflammation.

Scientists uncover mode of action of enzyme linked with several types of cancer

Scientists at the Institute for Research in Immunology and Cancer (IRIC) of the Université de Montréal have discovered a key mechanism used by cells to efficiently distribute chromosomes to new cells during cell multiplication.

Oxidative stress strongly evident in the in-utero environment of the fetus with Down syndrome

A paper published in the Proceedings of the National Academy of Sciences by Tufts Medical Center and Tufts University researchers reports that amniotic fluid surrounding Down syndrome fetuses shows oxidative stress, a condition that could harm fetal cells and play a role in affected individuals. The results demonstrate secondary adverse consequences of Down syndrome and suggest potential prenatal therapies.

Scientists create pig stem cells

Scientists have managed to induce cells from pigs to transform into pluripotent stem cells - cells that, like embryonic stem cells, are capable of developing into any type of cell in the body. It is the first time in the world that this has been achieved using somatic cells (cells that are not sperm or egg cells) from any animal with hooves (known as ungulates).

Closing gaps in the human genome using sequencing by synthesis

Sequence gaps in human chromosome 15 have been closed by the application of 454 technology. Researchers writing in BioMed Central's open access journal Genome Biology have described a simple and scalable method for finishing non-structural gaps in genome assemblies.

Glioblastoma may originate in neural stem cells

University of Michigan scientists have found that a deficiency in a key tumor suppressor gene in the brain leads to the most common type of adult brain cancer. The study, conducted in mice that mimic human cancer, points the way to more effective future treatments and a way to screen for the disease early.
