DNA News and Research

RSS

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

UiO researchers discover enzyme critical for spread of cancer

Potential diagnostic method to identify subset of patients with chronic fatigue syndrome

For the first time, researchers have landed on a potential diagnostic method to identify at least a subset of patients with chronic fatigue syndrome (CFS), a complex disorder with no known definitive cause or cure.

New gene delivery vehicle opens route to the heart of cells in solid tumors

There are plenty of effective anticancer agents around. The problem is that, very often, they cannot gain access to all the cells in solid tumors. A new gene delivery vehicle may provide a way of making tracks to the heart of the target.

MRSA outbreak tracked and contained using DNA sequencing

Scientists have used DNA sequencing for the first time to effectively track the spread of, and ultimately contain, an outbreak of methicillin-resistant Staphylococcus aureus (MRSA), according to new research published in The Lancet Infectious Diseases.

DNA sequencing helps detect MRSA outbreaks in hospitals

This study used DNA sequencing to examine an outbreak of MRSA in a hospital, to uncover new cases and, as the study developed, to intervene in the outbreak to end it more quickly. Sequencing illuminated each person infected and described the transmission of MRSA between people coming to the hospital and within the hospital.

Biofactory introduces FastFraX FMR1 Identification Kit at MEDICA 2012

The Biofactory, a biomedical incubator based in Singapore, has launched a new genetic test at MEDICA 2012, the world's largest medical trade fair. Called FastFraX, this genetic test is able to effectively screen for Fragile X Syndrome (FXS), a genetic condition that is the most common form of inherited intellectual disability.

Gene variants involved in glutamatergic transmission appear to increase risk of depression

Researchers using a new approach to identifying genes associated with depression have found that variants in a group of genes involved in transmission of signals by the neurotransmitter glutamate appear to increase the risk of depression.

Antioxidant imbalance in abnormal sperm

An imbalance exists in oxidative stress markers, such as reactive nitrogen species, reactive oxygen species, and total antioxidant capacity, in infertile men with abnormal semen parameters, report researchers.

Whole genome sequencing could become prenatal standard of care

Whole genome sequencing of the DNA code of prenatal samples accurately and quickly identifies the location of chromosomal abnormalities, and could become a prenatal standard of care, researchers propose.

Autism Speaks releases biological and clinical data from 383 new AGRE families

Autism Speaks, the world's leading autism science and advocacy organization, is proud to announce the release of biological and clinical data from 383 new families participating in Autism Speaks Autism Genetic Resource Exchange (AGRE) to researchers. AGRE is a resource for scientists that is comprised of clinical and biological data from families who have two or more children on the autism spectrum.

Longer looks: People with mental disabilities have a vote; Genome sequencing raises hope - also anxiety

I may get Alzheimer's disease, I was told after getting my DNA analyzed. I could suffer the consequences of an abnormal blood clot in my heart or my brain. Or perhaps I'll suffer from a disease called primary myelofibrosis that's caused by an overactive bone marrow. All of these were possible outcomes, based on my genetic profile. In each case, the test only gives an increased risk for disease, not a definitive diagnosis.

Immunomic Therapeutics initiates JRC-LAMP-vax vaccine Phase I trial in Sugi allergy

Immunomic Therapeutics, Inc., a leader in developing novel allergy immunotherapies, announced today that it has dosed the first patient in a Phase I clinical trial of its lead candidate, JRC-LAMP-vax vaccine, at its clinical site in Honolulu, Hawaii. Initial subjects include Japanese ex-patriates previously exposed to Japanese red cedar, or "Sugi," as it is known in Japan.

Plexxikon updates Zelboraf Phase 1 data on BRAF V600E mutation-positive melanoma

Plexxikon today announced that updated Phase 1 clinical data of Zelboraf (vemurafenib) were presented at the Society for Melanoma Research (SMR) 2012 Congress, held November 8-11 in Los Angeles, CA.

Study reveals increased risk of leukemia among Chernobyl cleanup workers

A 20-year study following 110,645 workers who helped clean up after the 1986 Chernobyl nuclear power plant accident in the former Soviet territory of Ukraine shows that the workers share a significant increased risk of developing leukemia. The results may help scientists better define cancer risk associated with low doses of radiation from medical diagnostic radiation procedures such as computed tomography scans and other sources.

ACS Prized Science video features advances in personalized medicine

Personalized medicine - the promise of customizing treatments that will work best for each individual patient - could get a boost from advances in understanding how the proteins that help determine health and disease take the three-dimensional shapes needed to work in the body. That's the message of the latest episode of the 2012 edition of a popular video series from the American Chemical Society (ACS), the world's largest scientific society.
