Protein ATM prevents DNA damage from persisting through generations

A protein long known to be involved in protecting a cell from genetic damage has been found to play an even more important role in protecting the cell's offspring.

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.

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.

Training autistic brains to recognize visual and vocal cues

To understand the meaning of a conversation, kids automatically do what adults do - besides processing the meaning of words, they unconsciously "read" the expression on a person's face and listen to their tone of voice, then integrate that information with the context at hand to discern meaning, be it humor, anger, irony or straightforwardness.

Thousands of children and teens diagnosed with diabetes each year in the U.S.

According to a major national study, as many as 15,000 children and adolescents in the United States are diagnosed with type 1 diabetes, and about 3,700 youth are diagnosed with type 2 diabetes each year.

Role of environmental factors in the development of Parkinson's disease

Scientists at the Buck Institute for Age Research have shown that combining two environmental toxic substances accelerated age-related degeneration in neurons associated with Parkinson's disease (PD) in mice.

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.

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).

Pediatric chronic disease poses future health and welfare challenges

The increased incidence of chronic conditions among American children predicts serious strains on health care and social welfare systems in the future, caution investigators from Massachusetts General Hospital (MGH) and Harvard School of Public Health (HSPH).

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.

Scoliosis gene found

Physicians have recognized scoliosis, the abnormal curvature of the spine, since the time of Hippocrates, but its causes have remained a mystery -- until now. For the first time, researchers have discovered a gene that underlies the condition, which affects about 3 percent of all children.
