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).

Inovio to update HVTN 080 Phase I clinical study for HIV at HVTN Conference

Inovio Pharmaceuticals, Inc., a leader in the development of therapeutic and preventive vaccines against cancers and infectious diseases, announced today that Dr. Spyros Kalams will provide an update of interim immune responses and safety results from the HVTN 080 Phase I clinical study of Inovio's PENNVAX-B HIV DNA vaccine in a preventive setting.

Research on fruit flies reveal novel human pain gene

While it has become clear in recent years that susceptibility to pain has a strong inherited component, very little is known about actual "pain genes" and how they work. In the November 12th issue of Cell, researchers at Children's Hospital Boston and their collaborators report on a novel human pain gene. People with minor variations in this gene showed clear differences in susceptibility to acute heat pain and chronic back pain.

PenCLAHRC provides funding to support C. difficile research

The Peninsula Collaboration for Leadership in Applied Health Research and Care (PenCLAHRC) has provided funding to support joint research between the University of Exeter and the Royal Devon & Exeter NHS Foundation Trust to investigate why some cases of Clostridium difficile infection (CDI) are more difficult to treat than others and also why some cases result in more incidences of relapses.

NCI awards $11.5 million to Fred Hutchinson Center for breast cancer research

The National Cancer Institute has awarded $11.5 million to Fred Hutchinson Cancer Research Center to lead a five-year, Seattle-based breast cancer research consortium. The goal of the endeavor is to positively impact breast cancer prevention, detection, treatment and care of women who have or are at risk for the disease.

PPH uses Xenex PX-UV disinfection system to destroy microorganisms causing HAIs

Palomar Pomerado Health (PPH) today announced it is the first health system in California to use the Xenex PX-UV disinfection system in its patient and operating rooms. The Xenex system is the fastest, safest and most cost-effective method for the advanced cleaning of hospital rooms in the world today, scientifically proven to destroy all major classes of microorganisms that cause hospital acquired infections (HAIs), such as MRSA and Clostridium difficile (C. diff).

Novel mechanism regulating circadian rhythm identified

Scientists from the Florida campus of The Scripps Research Institute have identified for the first time a novel mechanism that regulates circadian rhythm, the master clock that controls the body's natural 24-hour physiological cycle. These new findings could provide a new target not only for jet lag, shift work, and sleep disturbances, but also for disorders that result from circadian rhythm disruption, including diabetes and obesity as well as some types of cancer.

MqsA and MqsR protein complex can disrupt drug-resistant biofilm formation

When a foreign object such as a catheter enters the body, bacteria may not only invade it but also organize into a slick coating - a biofilm - that is highly resistant to antibiotics. Like sophisticated organized crime rings, biofilms cannot be defeated by a basic approach of conventional means. Instead doctors and drug developers need sophisticated new intelligence that reveals the key players in the network and how they operate. New research led by biologists at Brown University provides exactly that dossier on some key proteins in the iconic bacterium E. coli.

Marker for aggressive form of idiopathic pulmonary fibrosis discovered

A diagnosis of idiopathic pulmonary fibrosis is not much better than a death sentence, given a survival rate averaging 4 to 6 years as the disease robs its victim of the ability to breathe.

Cyclacel announces publication of sapacitabine in British Journal of Cancer

Cyclacel Pharmaceuticals, Inc., a biopharmaceutical company developing oral therapies that target the various phases of cell cycle control for the treatment of cancer and other serious diseases, announced today publication of data demonstrating that its sapacitabine oral nucleoside analog works synergistically with histone deacetylase (HDAC) inhibitors to induce significant reductions in tumor cell growth in both in vitro and in vivo preclinical models.

Researchers identify molecular cascade that drives sprouting in brain after stroke

A stroke wreaks havoc in the brain, destroying its cells and the connections between them. Depending on its severity and location, a stroke can impact someone's life forever, affecting motor activity, speech, memories, and more.

Genetic constitution can influence changes in tumor growth: Study

The genes we possess not only determine the color of our eyes and hair and how our bodies grow, they might also influence the changes that occur in tumors when we develop cancer.

New discovery can develop diagnostic test to identify gene mutation in AML

Decoding the DNA of a woman who died of acute myeloid leukemia (AML) has led researchers at Washington University School of Medicine in St. Louis to a gene that they found to be commonly altered in many patients who died quickly of the disease.

Epimutation in BRCA1 gene may cause early-onset of breast cancer

An Australian research team from the Peter MacCallum Cancer Centre, the University of Melbourne and the University of Queensland has identified a new risk factor for developing breast cancer. This has been published online in the journal Cancer Prevention Research.

Lung cancer in smokers versus non-smokers shows different genetic mutations

A group of scientists at B.C. Cancer Agency have found that lung cancers in smokers have different genetic mutations and look different than lung cancer in non-smokers. According to senior scientist at the BC Cancer Agency Research Centre Wan Lam, this finding is significant because it means that from now on, research, treatments and diagnostics should be tailored to the distinct genetic variations in the different lung cancers instead of expecting that a one-size fits all approach will work. He said, “At the current time, treatment does not distinguish between these different types. The subtypes are all grouped together. But with this work, we are beginning to tease out the subtypes.” The study was presented Tuesday at a conference in Philadelphia of the American Association of Cancer Research.
