RNA molecules can orchestrate gene activity across vast portions of the human genome

Large, seemingly useless pieces of RNA - a molecule originally considered only a lowly messenger for DNA - play an important role in letting cells know where they are in the body and what they are supposed to become, researchers at Stanford University School of Medicine have discovered.

New drug resistance screening method

A growing number of drug-resistant strains of HIV are a threat to the effectiveness of current treatments despite anti-HIV drug cocktails decreasing the number of HIV-related deaths and improving the quality of life for HIV patients.

Link between ciliary signaling and cancer

Submarines have periscopes. Insects have antennae. And increasingly, biologists are finding that most normal vertebrate cells have cilia, small hair-like structures that protrude like antennae into the surrounding environment to detect signals that control cell growth.

Breast cancer survival runs in the family

The chances of developing breast cancer are to some extent inherited, but important new findings suggest survival also runs in the family.

Key finding on ALS related protein

Chemists from UCLA and the University of Florence in Italy may have solved an important mystery about a protein that plays a key role in a particular form of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, a progressive, fatal neurodegenerative disorder that strikes without warning.

Support for chromosomal theory of cancer found in cancers' development of drug resistance

Thirty-six years into the war on cancer, scientists have not only failed to come up with a cure, but most of the newer drugs suffer from the same problems as those available in the pre-war days: serious toxicity, limited effectiveness and eventual resistance.

Scientists discover role of ataxia telangiectasia mutated protein in DNA repair

Scientists from the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), National Cancer Institute (NCI), and Integrative Bioinformatics Inc. have made an important discovery about the role of an enzyme called ataxia telangiectasia mutated protein (ATM) in the body's ability to repair damaged DNA.

Discovery of gene and mechanism essential to the embryonic development of the epididymis

Human sperm cells travel up to 6 meters in their transit from testes to penis, and most of that journey occurs in the epididymis, a tightly coiled tube that primes the cells for their ultimate task: fertilization.

New genetic test advances detection and diagnosis of muscular dystrophy

A new genetic test targeting the most common types of muscular dystrophy--those caused by mutations in the dystrophin gene--is far quicker with greater accuracy and sensitivity than existing tests.

Men and women with multiple sclerosis equally transmit the genetic risk of the disease to their children

The research contradicts the results of a recent study, which found affected fathers were more likely than affected mothers to transmit the risk of developing MS to their children.

Notch2 locus predicts prognosis in brain tumor patients

PLoS ONE has just published a study which defines a gene locus on chromosome 1 that predicts prognosis of brain tumor patients and may even set the basis for the development of more efficient drugs to combat brain cancer.

New insight into the mechanism by which glial cells recognize and myelinate axons

In a host of neurological diseases, including multiple sclerosis (MS) and several neuropathies, the protective covering surrounding the nerves - an insulating material called myelin - is damaged.

Breakthrough in understanding of noroviruses

A breakthrough announced this week by scientists at the University of Southampton's School of Medicine will lead to greater understanding of noroviruses, the most common cause of non-bacterial gastroenteritis around the world.

Gene variant increases risk for alcoholism following childhood abuse

Girls who suffered childhood sexual abuse are more likely to develop alcoholism later in life if they possess a particular variant of a gene involved in the body's response to stress, according to a new study led by researchers at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH).

Absence of a gene called CD38 is a protective barrier to obesity

A search for the molecular clues of longevity has taken Mayo Clinic researchers down another path that could explain why some people who consume excessive calories don't gain weight.

Link between depression and low levels of folate

In research published in the July edition of the Journal of Epidemiology and Community Health, the York team led by Dr Simon Gilbody, concluded that there was a link between depression and low folate levels, following a review of 11 previous studies involving 15,315 participants.

A new system for collaboration in cell communication

Investigators from the Institute of Research in Biomedicine (IRB Barcelona) have identified a new signalling mechanism among cells in the fruit fly, Drosophila melanogaster.

Autism reversed in mice

Scientists in the United States have been able to reverse the effects of autism in specially bred mice.

New genetic marker characterizes aggressiveness of cancer cells

Levels of a small non-coding RNA molecule called let-7 appear to define different stages of cancer better than some of the "classical" markers for tumor progression, researchers from the University of Chicago report in the June 25, 2007, early online edition of the Proceedings of the National Academy of Sciences.
