- Losses of long-established genes contribute to human evolution
12-13-2007 · EurekAlert!
While it is well understood that the evolution of new genes leads to adaptations that help species survive, gene loss may also afford a selective advantage. A group of scientists at the University of California-Santa Cruz led by biomolecular engineering professor David Haussler has investigated this less-studied idea, carrying out the first systematic computational analysis to identify long-established genes that have been lost across millions of years of evolution leading to the human species.

- Repair of DNA by Brca2 gene prevents medulloblastoma
05-18-2007 · EurekAlert!
Investigators at St. Jude Children's Research Hospital have gained some of the first major insights into how certain genes known to prevent cancer also guide the normal development of the nervous system before birth and during infancy by repairing DNA damage.

- Isolation of a new gene family essential for early development
08-22-2007 · EurekAlert!
Researchers at BRIC, University of Copenhagen, have identified new gene family essential for embryonic development. The family controls the expression of genes crucial for stem cell differentiation, and the results may contribute significantly to the understanding of cancer development. The results are published in Nature, and it follows up on two other high-impact articles on related gene families published in Nature and Cell by the same researchers within the last year.

- Notorious cancer gene may work by destroying messenger
03-19-2007 · EurekAlert!
A new study suggests how a notorious cancer gene may contribute to tumor growth. The insight emerged from a long-running study of a protein called PMR1, the key player in an unusual mechanism that cells use to quickly stop production of certain important proteins.

- What memories are made of
01-03-2007 · EurekAlert!
Unraveling the differences between various kinds of memories depends on understanding changes that happen in the brain at the molecular level, says a professor at the University of Wisconsin-Milwaukee. To probe the exact role that genes and proteins play in the brain in response to experience, Fred Helmstetter compares fMRI in humans with gene expression in rats.

- New Alzheimer's findings: High stress and genetic risk factor lead to increased memory decline
08-27-2007 · EurekAlert!
High stress levels may contribute to memory loss among people at risk for developing Alzheimer's disease. The å4 variant of the apolipoprotein E (APOE) gene contributes to the risk for memory loss related to Alzheimer's disease.

- Insulin regulates the secretion of the antiaging hormome Klotho
11-27-2007 · EurekAlert!
Dr. Carmela Abraham, a professor of biochemistry and medicine at Boston University School of Medicine, reports this week in the Proceedings of the National Academy of Sciences new findings on Klotho, an antiaging gene that is associated with life span extension in rodents and humans. Dr. Abraham's interest in Klotho stems from her studies comparing the expression of genes in young and old brains.
