Microarray-based genomic selection accelerates discovery of subtle DNA variations

A new technology developed by scientists at Emory University will allow researchers to more easily discover subtle and overlooked genetic variations that may have serious consequences for health and disease.

Improving working memory by computerized strategy in ADHD

Attention-deficit/hyperactivity disorder (ADHD), a state of serious impairments in both learning ability and social functioning, is one of many labels for one of the most prevalent conditions in child psychiatry, and, undoubtedly, the most controversial, which partly persists into adulthood.

Transthyretin protein may accelerate atherosclerosis

Scientists report in the November 2007 issue of the Journal of Lipid Research that a protein called transthyretin (TTR) that is present in the blood may accelerate the development of atherosclerosis - a potentially fatal heart disease in which the arteries are progressively narrowed and hardened over time, reducing blood flow to the heart.

A tumor-blocking protein may be key in developing deadly form of pancreatic cancer

A tumor-blocking protein previously implicated in prostate and breast cancer development may also be behind the most aggressive type of pancreatic cancer. Researchers at the Kimmel Cancer Center at Jefferson in Philadelphia have discovered that the protein pp32 – which normally applies the brakes on a cancer-causing gene – is missing in an aggressive form of pancreatic cancer.

Genome update defines landscape of breast and colon cancers

One year after completing the first large-scale report sequencing breast and colon cancer genes, Johns Hopkins Kimmel Cancer Center scientists have studied the vast majority of protein-coding genes which now suggest a landscape dominated by genes that each are mutated in relatively few cancers.

Feline virus, antiviral drug studied to understand drug resistance

Researchers at Ohio State will spend the next two years testing their theories about just how an AIDS-like virus in cats is able to resist the powerful medicines that are thrown against it.

Natural selection at the genetic level

In a molecular tour de force, researchers at the University of Wisconsin-Madison have provided an exquisitely detailed picture of natural selection as it occurs at the genetic level.

First animal model of age-related macular degeneration

Researchers at the University of Pennsylvania School of Medicine have created the first animal model of age-related macular degeneration (AMD) caused by a mutation known to produce disease in people, an important first step in developing treatments.

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?

Injectable antibody reverses cognitive deficits in mice

A special protein can be injected into the body to reverse learning problems in mice that have an animal version of Alzheimer's disease, Saint Louis University researchers have found.

Mario Capecchi shares Nobel Prize in medicine for knockout mice technology

Mario R. Capecchi, Ph.D., distinguished professor of human genetics and biology at the University of Utah's Eccles Institute of Human Genetics and a Howard Hughes Medical Institute investigator, has won the 2007 Nobel Prize in Physiology or Medicine.

Three new genes found that cause lung cancer

Researchers at Cold Spring Harbor Laboratory (CSHL) have discovered three genes that interact with cancerous results in 20% of lung cancers.

Latest death in Indonesia from bird flu takes toll up to 87

The Indonesian health ministry says the 44-year-old woman was from Pekan Baru city on Sumatra, and was apparently treated for fever at several hospitals before finally being admitted to Arifin Achmad hospital on October 4th where she died the following day.
