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).

Researchers find new evidence to support structure-based classification system for viruses

Professor Robert Sinclair at the Okinawa Institute of Science and Technology Graduate University and Professor Dennis Bamford and Dr. Janne Ravantti from the University of Helsinki have found new evidence to support a classification system for viruses based on viral structure.

Study finds biochemical pathway that triggers regrowth of breast cancer stem cells after chemotherapy

Working with human breast cancer cells and mice, researchers at Johns Hopkins say they have identified a biochemical pathway that triggers the regrowth of breast cancer stem cells after chemotherapy.

Epigenetic changes that affect formation of new muscle cells may be contributing factor to obesity

Obesity is associated with reduced muscle mass and impaired metabolism. Epigenetic changes that affect the formation of new muscle cells may be a contributing factor, according to new research from Lund University, Sweden.

U of T study uncovers gene that may play key role in obesity

A University of Toronto (U of T) study on fruit flies has uncovered a gene that could play a key role in obesity in humans.

Scientists explore role of salt and immune system in raising blood pressure of females

Many of us have noted how our hands and feet swell after eating too much salt. Now scientists are exploring how high salt intake can also make cells throughout the body of females swell, rupture, dump their contents and die, triggering an immune reaction that contributes to chronic high blood pressure.

Danish research may pave way for immunological treatment of cancer

Researchers from Aarhus University have found an important piece of the puzzle leading towards an understanding of how our innate immune system reacts against viral infections and recognises foreign DNA, for example from dying cancer cells.

Scientists engineer smallest CRISPR-Cas9 system to date

Scientists at the Center for Genome Engineering, within the Institute for Basic Science0, in collaboration with KIM Eunji and KIM Jeong Hun have engineered the smallest CRISPR-Cas9 to date, delivered it to the muscle cells and in the eyes of mice via adeno-associated viruses and used it to modify a gene causing blindness.

New imaging technology catches DNA naturally fluorescing

Many of the secrets of cancer and other diseases lie in the cell's nucleus. But getting way down to that level -- to see and investigate the important genetic material housed there -- requires creative thinking and extremely powerful imaging techniques.

Stem cells collected from fat more stable than previously thought, Penn study shows

Adult stem cells collected directly from human fat are more stable than other cells - such as fibroblasts from the skin - and have the potential for use in anti-aging treatments, according to researchers from the Perelman School of Medicine at the University of Pennsylvania.

Researchers provide insight into causes of left or right-handedness

A preference for the left or the right hand might be traced back to that asymmetry. "These results fundamentally change our understanding of the cause of hemispheric asymmetries," conclude the authors. The team report about their study in the journal eLife.

DNA computer could be important step towards development of smart, 'intelligent' drugs

Researchers at Eindhoven University of Technology present a new method that should enable controlled drug delivery into the bloodstream using DNA computers.

New method that detects NMD efficiency could help in treatment of many diseases

In cells, DNA is first converted to RNA, and RNA is next converted to proteins--a complicated process involving several other steps. Nonsense-mediated RNA decay is a processing pathway in cells that, like a broom, cleans up erroneous RNA to prevent its productive conversion into an aberrant protein, which could lead to disease.
