Spread of endogenous retrovirus K is similar in the DNA of humans and rhesus monkeys

According to paleontologic and molecular studies, the chimpanzee (Pan troglodytes) is the closer relative to the humans (Homo sapiens) and that both lineages had a common ancestor at 5 to 7 million years ago.

African-American men have a slightly higher risk of PSA recurrence

African-American men are more likely to have their prostate cancer return after treatment, but their disease is no more aggressive when it does recur than that of their white counterparts, according to a study led by Duke Prostate Center researchers.

Network approach finds potential breast cancer susceptibility gene

Like a crossword-puzzle solver who uses the letters in some answers to figure out others, researchers at Dana-Farber Cancer Institute and an international group of collaborators have used data on genes involved in inherited forms of breast cancer to identify a gene linked to non-hereditary cases of the disease.

Genomic technologies to identify toxic chemicals should be developed

A new report from the National Research Council recommends that government agencies enhance their efforts to incorporate genomic data into risk assessments of chemicals and medicines, and calls for a concerted effort to fully develop these methods' potential to protect public health.

Cautious optimism for new Alzheimer's medications

Alzheimer's disease takes a long time to develop, which suggests that it may be possible to design drugs that work early in the disease process, to delay the start of symptoms.

Antibody repairs myelin in lab study of multiple sclerosis and related disorders

Mayo Clinic researchers have found that a human antibody administered in a single low dose in laboratory mouse models can repair myelin, the insulating covering of nerves that when damaged can lead to multiple sclerosis and other disorders of the central nervous system.

Better understanding of what genomic changes paved the way for modern humans

Researchers have answered a similarly vexing (and far more relevant) genomic question: Which of the thousands of long stretches of repeated DNA in the human genome came first?

Smoking appears to have no effect on the progression of multiple sclerosis

Contrary to an earlier report, smoking appears to have no effect on the progression of multiple sclerosis (MS), according to a study published in the October 9, 2007, issue of Neurology®, the medical journal of the American Academy of Neurology.

Relatives of patients with Parkinson's disease may have an increased risk of developing dementia

Parkinson's disease is characterized by a decline in the functions of the central nervous system, such as motor skills and speech. Several studies have shown an increased risk of dementia in first-degree relatives of Parkinson's disease patients, while other studies have not confirmed the association, according to background information in the article.

One injection of gene therapy spreads through brain in animal study

By targeting a site in a mouse brain well connected to other areas, researchers successfully delivered a beneficial gene to the entire brain - after one injection of gene therapy.

New insight on jumping genes

Keck Graduate Institute (KGI) announced that Dr. Animesh Ray, KGI professor and director of KGI's PhD program, has published a paper in the international online journal PLoS ONE that sheds new light on the evolution of moveable genetic elements, or "jumping genes."

Link between woman's hips and daughter's risk of breast cancer

In a study of the maternity records of more than 6,000 women, David J.P. Barker, M.D., Ph.D., and Kent Thornburg, Ph.D., of Oregon Health & Science University discovered a strong correlation between the size and shape of a woman's hips and her daughter's risk of breast cancer.
