Genomic analysis may one day be a primary diagnostic tool for physicians deciding on a course of treatment for trauma

The researchers showed that state-of-the-art techniques for rapidly analyzing changes in activity of all human genes will likely produce useful insights into the health of critically ill patients. The findings, which are available online and will be published in the March 29 issue of the Proceedings of the National Academy of Sciences, make it possible for physicians to begin answering important questions about critical care through genomic analysis.

DNA weak links may provide clues to cancer biology

The chromosomes of mammals, including humans, contain regions that are particularly prone to breaking under conditions of stress and in cancer. Now, new research by geneticists at Duke University Medical Center finds that yeast cells also contain such weak links in DNA and begins to reveal the molecular characteristics of these links that might help to explain them.

Genetic examinations of trauma, burn victims produce consistent results

A genetic tool with the potential to identify which trauma and burn patients are most likely to become seriously ill has worked consistently in a wide range of experimental clinical settings - an important hurdle to overcome before the method is routinely used in emergency rooms and intensive care units.

DNA ejection from single phage particles

Studying phage, a primitive class of virus that infects bacteria by injecting its genomic DNA into host cells, researchers have gained insight into the driving force behind this poorly understood injection process, which has been proposed in the past to occur through the release of pressure accumulated within the viral particle itself.

Air Genome Project to sample air using whole genome shotgun sequencing

The J. Craig Venter Institute is launching a pilot project to better understand the diversity of microbes in urban air. In addition to more deeply characterizing the microbes we breathe every day, researchers anticipate that the results will provide information vital to designing systems that detect potentially dangerous biological substances in the air.

Genome clues to amoebic dysentery

Each year, there are an estimated 50 million cases of amoebic dysentery, causing up to 100,000 deaths, mostly in developing countries. On Thursday 24 February 2005, researchers at the Wellcome Trust Sanger Institute and their colleagues reported in Nature magazine the genome sequence of the parasite that causes the disease, Entamoeba histolytica.

Caution against FDA approval of race-based pharmaceutical

New York University Sociologist Troy Duster concludes that a pharmaceutical to combat heart disease among blacks is based on faulty research and urges the Food and Drug Administration to obtain more reliable data before approving the drug.

Common epigenetic problem doubles cancer risk

In experiments with mice, a team of scientists from the United States, Sweden and Japan has discovered that having a double dose of one protein is sufficient to change the normal balance of cells within the lining of the colon, thereby doubling the risk that a cancer-causing genetic mutation will trigger a tumor there.

Novel genetic test helps detect mutations that may be missed by conventional DNA test

Researchers have identified a genetic test that when used with DNA testing would detect a higher number of genetic mutations in colorectal cancer patients, according to a study in the February 16 issue of JAMA, a theme issue on medical applications of biotechnology.

The link between intelligence and dementia

Scientists have turned to the brightest brains in Britain in a bid to understand the link between intelligence and dementia.

New primate-specific gene family that spans about 10% of human chromosome 2

A team of scientists led by Peer Bork, Ph.D., Senior Bioinformatics Scientist at the European Molecular Biology Laboratory, report today in the journal Genome Research that they have identified a new primate-specific gene family that spans about 10% of human chromosome 2.

Findings could lead to new asthma treatment based on individual genetic profiles

Children who suffer from acute asthma attacks share a genetic profile that appears to be unique to these children, according to a new study by researchers at Cincinnati Children's Hospital Medical Center. The discovery opens the door to the possibility of designing treatments specifically tailored to children who suffer from the severest forms of asthma.

Novel nanotechnology detects human DNA mutations

Researchers at Nanosphere, Inc. have reported unprecedented benefits in the company's technology for the medical analysis of human DNA.

New insight into how tumor cells can become resistant to anti-cancer therapy

The scientists observed that a protein called P-glycoprotein (P-gp), which causes resistance to chemotherapy in many tumor types, is able to physically “jump” or transfer between tumor cells and retain its functional properties, protecting otherwise sensitive cells from the effects of anti-cancer treatment in vivo and in vitro.

Scientists are a step closer to developing drug targets to treat fungal meningitis

Scientists are a step closer to developing drug targets to treat fungal meningitis -- the infection linked to at least three deaths on Vancouver Island -- thanks to the sequencing of two Cryptococcus genomes by an international team that included researchers at the University of British Columbia and the BC Cancer Agency's Michael Smith Genome Sciences Centre in Vancouver.

Human Genome Project may have made traditional race-based measurements of human differences obsolete

New and sophisticated methods for studying the relationship between human genetic differences, the environment, health and behavior, all made possible by the completion of the Human Genome Project, have made traditional race-based measurements of human differences obsolete

Scientists discover that microRNAs regulate thousands of human genes

For many years, DNA and proteins have been viewed as the real movers and shakers in genomic studies, with RNA seen as little more than a messenger that shuttles information between the two.

Missing sequence of the human Y chromosome may contain genes controlling stature and tumor development

Scientists have reported in the journal Genome Research that they have successfully cloned and characterized a previously intractable DNA sequence: a 554-kilobase-pair genomic segment near the centromere of the human Y chromosome. This sequence contains eight putatively active genes that could be implicated in sex-associated height differences and gonadal tumor development.
