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).

Epigenetic modification may be cause of adult throat cancers linked to alcohol, tobacco use

A team of researchers at the Research Institute of the McGill University Health Centre has found an epigenetic modification that might be the cause of 15% of adult cancers of the throat linked to alcohol and tobacco use.

Genetic testing at UMMC helps doctors identify effective medication for heart stent patients

The University of Maryland Medical Center is now offering a simple genetic test to patients who receive heart stents to determine whether they have a genetic deficiency that affects how they respond to a common drug to prevent blood clots.

Forensic experts need statistical models to give weight to DNA-evidence

How do forensic scientists deal with complex DNA-evidence found at crime scenes? Giulia Cereda developed new statistical models to analyse them.

UCM scientists design biosensor capable of detecting cancer autoantibodies at early stages

Before a malignant tumor is developed, the immune system tries to fight against proteins that are altered during their formation, producing certain cancer antibodies.

Study shows how phage-resistant cells become susceptible upon co-incubation with sensitive bacteria

Bacteriophages (phages) are probably the most abundant entities in nature, often exceeding bacterial densities by an order of magnitude.

Roswell Park study provides new insights into gene mutations that can lead to cancer

Predisposition to cancer and cancer progression can result from gene mutations that cause elevated rates of genetic damage.

Study strengthens therapeutic potential for niacin-based diet in treatment of Parkinson's disease

People with certain forms of early-onset Parkinson's disease may benefit from boosting the amount of niacin in their diet, according to new research from the University of Leicester.

Researchers identify new subgroup of cervical cancers with different genetic features

A team of University of South Carolina scientists led by Carolyn Banister and Phillip Buckhaults has identified a new subtype of cervical cancer that, like most cervical cancers, is triggered by human papillomavirus (HPV) but whose growth is not directed by the virus, suggesting that therapy targeting these tumors' distinct genomic pathways may improve patient outcomes over standard treatment.

Surveillance machinery in cells recognizes and destroys defective genetic material, research shows

New research out of Case Western Reserve University School of Medicine describes a mechanism by which an essential quality control system in cells identifies and destroys faulty genetic material. The findings were published online December 23 in Nature Communications.

MGH researchers identify gene mutations linked to rare congenital condition involving lack of nose

Researchers from Massachusetts General Hospital led a large, international research team that has identified gene mutations associated with a rare congenital condition involving the absence of a nose and often accompanied by defects involving the eye and reproductive systems.

Archaeologist discovers 800-year-old genomes from bacterial infection in Byzantine skeleton

Eight hundred years ago, in a hardscrabble farming community on the outskirts of what was once one of the fabled cities of the ancient world, Troy, a 30-year-old woman was laid to rest in a stone-lined grave.

Retroviruses almost several hundred million years older than previously thought

Retroviruses - the family of viruses that includes HIV - are almost half a billion years old, according to new research by scientists at Oxford University.

Scientists crack genetic code to identify men at risk for prostate cancer that spreads after treatment

Canadian prostate cancer researchers have discovered the genetic fingerprint that explains why up to 30 per cent of men with potentially curable localized prostate cancer develop aggressive disease that spreads following radiotherapy or surgery.

Johns Hopkins researchers identify new biological target for treating spinal muscular atrophy

Johns Hopkins researchers along with academic and drug industry investigators say they have identified a new biological target for treating spinal muscular atrophy.

Epigenetic changes favor development of fatty liver in humans and mice

Mice with a strong tendency to obesity already exhibit epigenetic changes at six weeks of age, inducing the liver to amplify its production of the enzyme DPP4 and release it into the circulation. Over the long term, this favors the development of a fatty liver.

UI scientists reveal how high-dose vitamin C damages cancer cells

Vitamin C has a patchy history as a cancer therapy, but researchers at the University of Iowa believe that is because it has often been used in a way that guarantees failure.

Penn study finds evidence of AD neuropathology in post-mortem brains of LBD patients

Patients who had a diagnosis of Parkinson's disease (PD) with dementia (PDD) or dementia with Lewy bodies (DLB) and had higher levels of Alzheimer's disease (AD) pathology in their donated post-mortem brains also had more severe symptoms of these Lewy body diseases (LBD) during their lives, compared to those whose brains had less AD pathology, according to research from the Perelman School of Medicine at the University of Pennsylvania.
