Discovery of genetic link between obesity and colon cancer risk

A new study reveals the first-ever genetic link between obesity and colon cancer risk, a finding that could lead to greater accuracy in testing for the disease, said a researcher at the University of Alabama at Birmingham (UAB).

Molecule provides new understanding of cause of colon cancer

Scientists investigating a molecule known to play a key role in causing colon cancer have made a series of ground-breaking discoveries that could have major implications for future treatment of the disease, responsible for 655,000 deaths worldwide per year. Their findings are published in the journal Cancer Research.

New gout gene discovery

Researchers have identified two new genes - and confirmed the role of a third gene - associated with increased risk of higher levels of uric acid in the blood, which can lead to gout, a common, painful form of arthritis.

A DNA-based vaccine shows promise against avian flu

Though it has fallen from the headlines, a global pandemic caused by bird flu still has the United States' Centers for Disease Control and Prevention on high alert. Yet, to date, the only vaccines that have proven even semi-effective are produced in chicken eggs, take five to six months to prepare and act against a single variant of the H5N1 virus, which mutates incredibly quickly.

Multiple sclerosis patients have higher spinal fluid levels of suspicious immune molecule

A protein that helps keep immune cells quiet is more abundant in the spinal fluid of patients with multiple sclerosis (MS), further boosting suspicion that the protein, TREM-2, may be an important contributor to the disease.

Genetic link found to sleep disorder narcolepsy

New genetic research may help explain the unusual and distressing sleep disorder narcolepsy.

Sequencing thousand and one genomes

Researchers at the Max Planck Institute for Developmental Biology in Tuebingen, Germany, reported the completion of the first genomes of wild strains of the flowering plant Arabidopsis thaliana. The entire genomes of two individuals of this species, one from Ireland, the other from Japan, have now been compared in great detail. They were found to be astonishingly different from each other, as Detlef Weigel and his colleagues write in Genome Research.

Women warned about talcum powder ovarian cancer risk

Scientists have issued a warning to women about using talcum powder - they say it increases their risk of developing ovarian cancer.

Breast, ovarian cancer prediction models more accurate for white women than Asian-American women

Two widely used prediction models for identifying a woman's risk for breast and ovarian cancer appear to be less reliable for Asian-American women compared with white women, according to a study in the October issue of the Journal of Clinical Oncology, Reuters Health reports.

New York City blacks more likely than other races to have high blood pressure, report finds

New York City blacks have the highest rate of high blood pressure of any racial or ethnic group in the city, according to a report released on Wednesday by the New York City Department of Health and Mental Hygiene, the Staten Island Advance reports.

Gene variant boosts risk of fatty liver disease

Researchers at UT Southwestern Medical Center have found that individuals who carry a specific form of the gene PNPLA3 have more fat in their livers and a greater risk of developing liver inflammation.

Sun exposure may have an anti-melanoma effect

Italian researchers have found a link between vitamin D and the risk of developing a melanoma and they say that individuals with certain variants in a vitamin D-related gene, called BsmI, may be at an increased risk of developing melanoma.

Genetic fishing expedition yields surprising catch important to mammals

Johns Hopkins investigators report the discovery of master controllers of a gene critical to human and all mammalian development by trawling, implausibly enough, through anonymous genetic sequences using tiny zebrafish embryos.

No such thing as a 'safe' suntan

Three review papers from leading researchers in the fields of cell biology, dermatology and epidemiology have looked closely at the effects on skin of UV radiation, including that from indoor tanning beds.

Muscle stem cell identity confirmed

A single cell can repopulate damaged skeletal muscle in mice, say scientists at the Stanford University School of Medicine, who devised a way to track the cell's fate in living animals. The research is the first to confirm that so-called satellite cells encircling muscle fibers harbor an elusive muscle stem cell.

Genetic screening effective for initial HIV treatment

A major study from a team of researchers from Weill Cornell Medical College and Massachusetts General Hospital has found that a recent change to HIV-treatment guidelines recommending genetic screening is cost-effective under certain conditions. The new recommendation suggests conducting a genetic screening test prior to prescribing the drug abacavir, one of the preferred first-line drugs for the treatment for HIV-infected adults.

Ethics of screening for Down Syndrome under question

A new analysis has revealed some troubling facts regarding the universally available genetic screening test for Down syndrome.

Prostate cancer genes behave like those in embryo

Gene activity in prostate cancer is reminiscent of that in the developing fetal prostate, providing further evidence that all cancers are not equal, Johns Hopkins researchers report. The finding could help scientists investigate how to manipulate the genetic program to fight a disease whose biology remains poorly understood despite more than half a century of investigation.

New results help predict treatment response in colorectal cancer

Genetic testing can identify a group of patients with advanced colorectal cancer who are likely to survive on average twice as long if treated with the drug cetuximab, late breaking results show.
