Gene variation associated with resistance to chemotherapy drug in women with breast cancer

Researchers have found links between an individual's genetics and their response to treatment with chemotherapy. The findings, by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and colleagues, show how a genetic variant, located in the SOD2 gene, may affect how a person responds to the chemotherapy drug cyclophosphamide. Cyclophosphamide is used in the treatment of breast and other cancers.

Researchers discover why Lou Gehrig's disease speeds along more rapidly in some patients than others

University of Florida scientists have discovered why a paralyzing brain disorder speeds along more rapidly in some patients than others - a finding that may finally give researchers an entry point toward an effective treatment for amyotrophic lateral sclerosis, often referred to as ALS or Lou Gehrig's disease.

Adolescents suffering from anxiety and depression should be screened for insomnia

The genes that play a role in adolescent insomnia are the same as those involved in depression and anxiety, according to a research abstract presented at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies.

Genetic and environmental relations between insomnia and intrusive thinking

The genetic factors that cause increased sleep problems during times of stress seem to be the same as those that make people with intrusive and ruminative thoughts have a higher prevalence of insomnia, according to a research abstract that will be presented on Tuesday, June 9, at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies.

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 shows how cells tell time

In a new study appearing online this week in the Proceedings of the National Academy of Sciences, Dr. Liu and his co-workers have found that this mold, which uses a protein called FRQ as the main gear of its clock, marks time by a sequence of changes in the protein's chemical structure.

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.

Stopping fatty change in heart cells

Heart failure is one of the world's most frequent causes of death - caused by conditions such as diabetes and obesity. With people who are overweight, the heart has to do more work in order to pump the blood through the circulatory system and this causes an increase in blood pressure.

New ‘molecular clock’ provides more accurate method of dating ancient human migration

Researchers at the University of Leeds have devised a more accurate method of dating ancient human migration - even when no corroborating archaeological evidence exists.

Small molecules mimic natural gene regulators

In the quest for new approaches to treating and preventing disease, one appealing route involves turning genes on or off at will, directly intervening in ailments such as cancer and diabetes, which result when genes fail to turn on and off as they should.

The colourful world of synesthesia

David Eagleman, Ph.D will explore the brilliant scope of the human mind in his forthcoming lecture at the University of Sydney on the perplexing cognitive condition, Synesthesia.

Researchers examine 'invading' bacteria in DNA - advanced warfare on the most elemental of levels

Researchers at Texas A&M University's Artie McFerrin Department of Chemical Engineering have discovered how certain types of bacteria integrate the DNA that they have captured from invading enemies into their own genetic makeup to increase their chances of survival.

Noninvasive screening test detects digestive cancers in multiple organs

Mayo Clinic researchers have demonstrated that a noninvasive screening test can detect not only colorectal cancer but also the common cancers above the colon -- including pancreas, stomach, biliary and esophageal cancers. This is one of more than 100 Mayo Clinic studies being presented at Digestive Disease Week 2009 in Chicago, May 30 - June 4.

Gene that stops or suppress cancer plays a role in cancer stem cells

A gene well known to stop or suppress cancer plays a role in cancer stem cells, according to a new study from the University of Michigan Comprehensive Cancer Center. The researchers found that several pathways linked to the gene, called PTEN, also affected the growth of breast cancer stem cells.

Linking microRNAs with cells that regulate the immune system could lead to new disease therapies

Linking genetic material microRNAs with cells that regulate the immune system could one day lead to new therapies for treating cancer, infections and autoimmune diseases, according to a Henry Ford Hospital study.

Discovery of gene that regulates tumors in neuroblastoma

Virginia Commonwealth University researchers have identified a gene that may play a key role in regulating tumor progression in neuroblastoma, a form of cancer usually found in young children. Scientists hope the finding could lead to an effective therapy to inhibit the expression of this gene.

Eye cancer patients want genetic testing to predict metastasis risk

If you had cancer and a genetic test could predict the risk of the tumor spreading aggressively, would you want to know - even if no treatments existed to help you?

Rapamycin epilepsy-prevention effect may be widely applicable

A drug with potential to prevent epilepsy caused by a genetic condition may also help prevent more common forms of epilepsy caused by brain injury, according to researchers at Washington University School of Medicine in St. Louis.
