Comparing chimp, human DNA
10-12-2006 · EurekAlert!Most of the big differences between human and chimpanzee DNA lie in regions that do not code for genes, according to a new study. Instead, they may contain DNA sequences that control how gene-coding regions are activated and read.

- Comparing chimp and human DNA
10-12-2006 · EurekAlert!
Scientists look to the chimpanzee genome to better understand our own. In a new study, researchers used comparative genomics to investigate the properties of a set of 202 carefully screened "highly accelerated regions." They searched for stretches of DNA that were highly conserved between chimpanzees, mice and rats, comparing those sequences to the human genome sequence in order to unravel the evolutionary forces at work behind the human genome's fastest evolving regions.

- Where broken DNA is repaired
08-02-2007 · EurekAlert!
Intricate DNA repair mechanisms in cell nuclei are constantly working to fix damaged DNA, but for mammalian cells, exactly where the repair work happens has been an unanswered question. By comparing computer models of damaged human DNA with microscopic images of radiation-induced damage in human cells, researchers at Lawrence Berkeley National Laboratory and their colleagues have found evidence for specific regions where broken DNA is concentrated for repair.

- Neuron cell stickiness may hold key to evolution of the human brain
11-02-2006 · EurekAlert!
The stickiness of human neurons may have been a key factor in why the human brain evolved beyond the brains of our primate relatives. In a study comparing the genomes of humans, chimpanzees and other vertebrates, researchers at the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Joint Genome Institute (JGI) found a strikingly high degree of genetic differences in DNA sequences that appear to regulate genes involved in nerve cell adhesion molecules.

- Human trial results show excellent safety data, from Geovax's DNA/MVA AIDS vaccines
02-06-2007 · EurekAlert!
GeoVax Labs, Inc. an Atlanta-based biotechnology company, today reported successful early results from two ongoing AIDS prevention Phase I human vaccine trials. Results from the first low-dose trial indicate a good safety profile as well as positive immune responses in human volunteers receiving 1/10th dose of GeoVax's AIDS vaccine. Results from a second larger full-dose trial also indicate a good safety profile in participants.

- LSU professor involved in genome sequencing of the first marsupial
05-09-2007 · EurekAlert!
Since the launch of the Human Genome Project, which released a first draft of the entire sequence of human DNA in 2001, many researchers have dedicated themselves to creating a library of comprehensive, species-specific genetic sequence "maps" available for study. Scientists at LSU recently took part in a multi-institutional effort spearheaded by the Broad Institute of MIT and Harvard University to sequence the complete genome of the gray, short-tailed opossum, Monodelphis domestica.

- 'Junk' DNA now looks like powerful regulator, Stanford researcher finds
04-23-2007 · EurekAlert!
Large swaths of garbled human DNA once dismissed as junk appear to contain some valuable sections, according to a new study by researchers at the Stanford University School of Medicine and the University of California-Santa Cruz. The scientists propose that this redeemed DNA plays a role in controlling when genes turn on and off.

- The wider view from a detailed focus
06-13-2007 · EurekAlert!
A major study of the organization and regulation of the human genome published today changes our concept of how our genome works. The exhaustive analysis of 1 percent of the genome gives an extensive view of genetic activity alongside the cellular machinery that allows DNA to be read and replicated. The complex tapestry of interwoven elements revealed today suggests that "our perspective of transcription and genes may have to evolve," the researchers state.

- New study suggests Concord grape juice may provide protection against breast cancer
08-09-2007 · EurekAlert!
According to a new study, published in the current issue of the Journal of Medicinal Foods, natural compounds in Concord grape juice protected healthy human breast cells from DNA damage. Healthy human breast cells were exposed in a test tube to an environmental carcinogen, benzo(a)pyrene, that is able to initiate a chain of events leading to breast cancer. However, the introduction of Concord grape juice compounds blocked the connection of the carcinogen to the DNA of the healthy cells.
