DNA News and Research

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).

Mutations make Staph more resistant to antibiotics

Scientists suppress NCoR1 protein and create mighty mice

A team of researchers at EPFL, the University of Lausanne and the Salk Institute created super strong, marathon mice and nematodes by reducing the function of a natural inhibitor, suggesting treatments for age-related or genetically caused muscle degeneration are within reach.

Regulated gene transcription more complex than previously thought

Cells develop and thrive by turning genes on and off as needed in a precise pattern, a process known as regulated gene transcription. In a paper published in the Nov. 9 issue of the Journal of Neuroscience, researchers at the University of California, San Diego School of Medicine say this process is even more complex than previously thought, with regulated genes actually relocated to other, more conducive places in the cell nucleus.

Study reveals role of circadian rhythms in regenerative capacity of skin stem cells

The investigation reveals the role of the daily biological clock (circadian rhythms) in the regenerative capacity of skin stem cells. Disruption of this rhythm results in premature tissue ageing and a greater predisposition to the development of skin tumours. The

Genetic sequencing key to fundamentally understanding diseases

What started back in 2004 as a three-person start-up may well be on its way to becoming a multi-million euro success story. Advanced by a team of young Dutch scientists pushing disruptive biotech innovations onto the market, the SME FlexGen is attracting the attention of some key investors and demonstrating the added value that public support can offer to innovative SMES, with the Eurostars funding programme leading the way.

Maryland anesthesiologist named 2011 Researcher of the Year

Often on the mind of Gary Fiskum, PhD, are the more than 250,000 people in the U.S. who get resuscitated from cardiac arrest each year, the 6 million living with traumatic brain injuries, and the wounded warriors whose brain whose brains sustain enormous G-forces from roadside bombs in the war zone.

Novel mathematical method reveals genetic distinction between individuals

At a time when profound gaps remain in our understanding of how one person's genes differ from another person's, developing accurate methods to interpret the human genome is essential to uncover population history, population relationships and the genetic basis of some of the most common diseases affecting society.

Johns Hopkins researchers unravel how breast cancer metastasizes

The spread of breast cancer is responsible for more than 90 percent of breast cancer deaths. Now, the process by which it spreads—or metastasizes—has been unraveled by researchers at Johns Hopkins. Reporting in two papers, the researchers have discovered the switch that enables breast cancer cells to travel to and be received in the lungs.
