First molecular-scale images of DNA binding to an adenovirus enzyme

The images, which appear on the cover of the October 2004 issue of Molecular and Cellular Proteomics, show how binding to DNA may stimulate the enzyme and are already being used to design new antiviral drugs to block this interaction.

Studies of human genetic variation have found strong evidence for the action of natural selection

One of the most comprehensive studies of the forces that have shaped patterns of human genetic variation has found strong evidence for the action of natural selection, which may help explain why certain people are at risk for a variety of conditions and others are not.

Flaw in DNA helps explain cancers and aging

Their finding explains how oxidative DNA damage - a process long believed to underlie cancers and aging - can create permanent genetic damage.

Computer model of damaged DNA bends the rules

Our knees may become stiff when injured, but banged up DNA becomes flexible, suggests the most detailed computer model of damaged DNA to date. Further, this flexibility explains how the body's enzymes recognize and fix damaged DNA.

What is Telomere crisis?

Telomere crisis is an important early event in the development of breast cancer, and its occurrence can be identified with precision, according to recent findings by a team of scientists at the Department of Energy's Lawrence Berkeley National Laboratory and the University of California at San Francisco.

Gene associated with susceptibility to developing type 1 diabetes

A new gene mutation identified by researchers at Baylor College of Medicine in Houston is part of the constellation of genes associated with susceptibility to developing type 1 diabetes. It could also play a role in the devastating complications of diabetes such as kidney failure.

The structure of AGT shows how one human protein reduces the potency of chemotherapy

The fine details of this x-ray structure may help scientists find ways to fight certain cancers, such as brain tumors, which express high levels of AGT making them resistant to chemotherapy.

First university-based research center devoted to studying epigenetics

With a $5 million, five-year federal grant, The Johns Hopkins University School of Medicine is establishing what is believed to be the first university-based research center devoted to studying epigenetics

Antarctic worms may hold the key to future storage of organ transplants

The secret to Antarctic worms’ survival in the most extreme conditions may have implications for future storage of organ transplants, say University of Otago researchers.

International research team have decoded the genetic blueprint of the tularemia (rabbit fever) bacterium

Two teams of researchers, one based in the United States and the other in Europe, have decoded the genetic blueprint of the tularemia (rabbit fever) bacterium, a highly infectious human and animal pathogen.

Research uncovers critical pieces of human genome

Researchers have found precisely the same sequences in the genomes of humans, rats, and mice; sequences that are 95 to 99 percent identical to these can be found in the chicken and dog genomes, as well.

Overview of West Nile virus before season starts

West Nile virus is a newly emergent virus of the family Flaviviridae, found in both tropical and temperate regions. It mainly infects birds, but is also the cause of a number of conditions in humans, horses, and some other mammals. It is transmitted by bites of infected mosquitoes.

DNA free radical damage research

Certain prostate cancer cell lines are unable to repair DNA damage caused by "free radicals," according to scientists at the National Institute of Standards and Technology (NIST) and National Institutes of Health (NIH). This type of damage has been implicated before in the development of prostate cancer, but the new research provides the first solid evidence that the normal repair process is altered in prostate cancer cells, possibly leading to a cascade of events that culminate in further DNA damage and cellular dysfunction.

Completion of the sequencing of human chromosome 19

The United States Department of Energy (DOE) Joint Genome Institute (JGI) and Stanford University report today the completion of the sequencing of human chromosome 19, the most gene-rich of all the human chromosomes. This achievement is described in the April 1, 2004 edition of the journal Nature.

The National Cancer Institute has awarded USC scientists $3.5 million for a study of the enzyme that faithfully copies our genetic information

The National Cancer Institute has awarded USC scientists $3.5 million for a study of the enzyme that faithfully copies our genetic information, enabling it to pass from one generation to the next. The grant will fund structural, biochemical and computer studies designed to reveal how the enzyme, DNA polymerase, makes so few mistakes.

How rat's genetic blueprint stacks up against those of mice and humans

An international research team, supported by the National Institutes of Health (NIH), today announced it has completed a high-quality, draft sequence of the genome of the laboratory rat, and has used that data to explore how the rat's genetic blueprint stacks up against those of mice and humans.
