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).

Brown University researchers describe new method to test HIV mutations

Tests that can distinguish whether HIV-positive people are infected with a drug-resistant strain or a non-resistant strain allow patients to get the most effective treatment as quickly as possible. In the November edition of the Journal of Molecular Diagnostics, a team of Brown University researchers describes a new method that works faster and more sensitively in lab testing than the current standard technologies.

Neutrophils kill invading microorganisms, starve microbes to death

The most frequent immune cells in the human blood, so-called neutrophils, efficiently kill invading microorganisms and slowly starve microbes to death by removing crucial trace elements. This is shown by researchers from Umeå University in Sweden in a study published in a special issue of Metallomics.

New blood test could help pair cancer patients with suitable therapy for their disease

CANCER RESEARCH UK-funded scientists have developed a blood test that could help pair cancer patients with the most suitable therapy for their disease and then track the tumour's progress to see if the treatment is working, according to research published today (Thursday) in Clinical Cancer Research.

Different Crohn's disease treatments affect children's gut microbes in distinct ways

Different treatments for Crohn's disease in children affects their gut mi-crobes in distinct ways, which has implications for future development of microbial-targeted therapies for these patients, according to a study led by researchers from the Perelman School of Medicine at the University of Pennsylvania.

How important is a mother’s diet before pregnancy? An interview with Dr Matt Silver

In humans, much is already known about the impact of maternal undernutrition during pregnancy, and its impact on growth, development and disease throughout the life course. However, until recently little was known about the effects of the nutritional environment around the time of conception.

Sense oligonucleotide antidote reverses actions of antisense antithrombotic drug, prevents bleeding

Researchers from Isis Pharmaceuticals (Carlsbad, CA) and Prysis Biotechnologies (Pudong, Shanghai, China) have demonstrated proof-of-concept for using a sense oligonucleotide to undo the effects of an antisense drug, an antithrombotic agent in this novel study.

Forces in external environmental and oxidation are greatest threats to DNA, study finds

A study led by Indiana University biologist Patricia Foster and colleagues has found that forces in the external environment and oxidation are the greatest threats to an organism's ability to repair damage to its own DNA.

Blocking the production of CHD4 protein may help increase effectiveness of AML treatments

Preclinical experiments led by a team of researchers at VCU Massey Cancer Center have shown that blocking the production of a protein known as chromodomain helicase DNA-binding protein 4 (CHD4) may help increase the effectiveness of first-line treatments for acute myeloid leukemia (AML), a particularly lethal blood cancer that is increasing in incidence among older adults.

ASF launches Autism Sisters Project to accelerate research into 'Female Protective Effect'

The Autism Science Foundation, a not-for-profit organization dedicated to supporting and funding autism research, today announced the launch of the Autism Sisters Project, a new initiative that will give unaffected sisters of individuals with autism the opportunity to take an active role in accelerating research into the "Female Protective Effect."

GENALICE’s Population Calling analysis module improves diagnosis, treatment of complex DNA diseases

Today, GENALICE is setting a new standard for ultra-fast and highly reliable detection of all DNA changes in large patient cohorts. In a one-hour online event, the complete genomes of 800 Alzheimer Disease (AD) patients were processed, and by ingeniously using the aggregate information from the complete group, detection of DNA changes, or variants, in individual patients was enhanced.

Quest Diagnostics scientists demonstrate new molecular combing technique that predicts cystic fibrosis, muscular dystrophy

Genetic testing for mutations beyond those currently recommended in medical guidelines may aid the identification of more couples at risk of having a child with cystic fibrosis, according to a study presented today at the 2015 American Society of Human Genetics Annual Meeting, which runs through October 10 in Baltimore, Maryland.

ATA announces research grants to support projects proposed by young researchers

The American Thyroid Association is pleased to announce that grants have been awarded to support projects proposed by leading young researchers. Three of these projects involve the genetic analysis of thyroid tumors carrying the BRAFV600E mutation, which is associated with the development of some forms of thyroid cancer and increased risk for distant metastases, more advanced disease, and higher mortality.

Tamoxifen drug clears MRSA, reduces mortality

Researchers at University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences have found that the breast cancer drug tamoxifen gives white blood cells a boost, better enabling them to respond to, ensnare and kill bacteria in laboratory experiments. Tamoxifen treatment in mice also enhances clearance of the antibiotic-resistant bacterial pathogen MRSA and reduces mortality.
