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).

New DNA-based test could better predict treatment outcomes for prostate cancer patients

Researchers at The Ontario Institute for Cancer Research and University Health Network, have identified a new DNA-based test that could be used to better predict how prostate cancer patients will respond to treatment and to prevent relapse.

Effecting changes to FosB gene could help control addiction, depression

Regulation of a single, specific gene in a brain region related to drug addiction and depression is sufficient to reduce drug and stress responses, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published October 27 online in the journal Nature Neuroscience.

Mayo Clinic study finds that chromosomal rearrangements can help trace lineage of lung cancer

A diagnostic test based on chromosomal rearrangements can trace the lineage of lung cancer to determine whether two separate lung cancers in the same patient are independent tumors or a tumor that has spread to another region of the lung, a Mayo Clinic study has found. For patients with multiple tumors, that distinction could mean the difference between early stage cancer that may be cured by surgery and incurable late-stage disease.

Study reveals ETEC bacteria's genetic composition

Enterotoxigenic Escherichia coli (ETEC) bacteria are responsible each year for around 400 million cases of diarrhoea and 400,000 deaths in the world's low- and middle-income countries. Children under the age of five are most affected.

Researchers refine diagnostic tools to predict treatment outcomes for children with neuroblastoma

Oncology researchers studying gene mutations in the childhood cancer neuroblastoma are refining their diagnostic tools to predict which patients are more likely to respond to drugs called ALK inhibitors that target such mutations. Removing some of the guesswork in diagnosis and treatment, the researchers say, may lead to more successful outcomes for children with this often-deadly cancer.

Researchers find way to defeat elusive target proteins in cancer cells

Researchers at Dana-Farber/Boston Children's Cancer and Blood Disorders Center have found a way to defeat one of the most tantalizing yet elusive target proteins in cancer cells - employing a strategy that turns the protein's own molecular machinations against it.

Scientists may have discovered new way to repair damaged tissue

By transforming human scar cells into blood vessel cells, scientists at Houston Methodist may have discovered a new way to repair damaged tissue. The method, described in an upcoming issue of Circulation (early online), appeared to improve blood flow, oxygenation, and nutrition to areas in need.

Researchers discover new genetic cause of rare, complex form of epilepsy

A research team led by scientists at the Scripps Translational Science Institute has used whole genome sequencing to identify a new genetic cause of a severe, rare and complex form of epilepsy that becomes evident in early childhood and can lead to early death.

Researchers obtain detailed picture of how Gas5 RNA interacts with steroid hormone receptors

It arises from what scientists previously described as "junk DNA" or "the dark matter of the genome," but this gene is definitely not junk.

Zinc supplements more beneficial for some people with diabetes

Researchers at the Johns Hopkins University School of Medicine and elsewhere have found that genetic differences may account for why zinc supplements are more beneficial to some people than to others for the prevention and control of diabetes. The results of their pilot study of a population of Old Order Amish is believed to be the first to point out the relevance of small genetic differences in response to zinc supplementation at play in diabetes management.

Olaparib shows promise for advanced cancers associated with BRCA1 and BRCA2 mutations

Olaparib, an experimental twice-daily oral cancer drug, produces an overall tumor response rate of 26 percent in several advanced cancers associated with BRCA1 and BRCA2 mutations, according to new research co-led by the Abramson Cancer Center of the University of Pennsylvania.

Scientists develop human stem cell disease model of Parkinson's disease in a dish

A team of scientists led by The New York Stem Cell Foundation Research Institute successfully created a human stem cell disease model of Parkinson's disease in a dish. Studying a pair of identical (monozygotic) twins, one affected and one unaffected with Parkinson's disease, another unrelated Parkinson's patient, and four healthy control subjects, the scientists were able to observe key features of the disease in the laboratory, specifically differences in the patients' neurons' ability to produce dopamine, the molecule that is deficient in Parkinson's disease.

Joslin researcher identifies molecular pathway that causes neural tube defects in diabetic pregnancies

Mary R. Loeken, Ph.D., Investigator in the Section on Islet Cell and Regenerative Biology at Joslin Diabetes Center and Associate Professor of Medicine at Harvard Medical School, has discovered a molecular pathway responsible for neural tube defects in diabetic pregnancies. Her latest research findings in this pathway were published in the October issue of Diabetes.

Researchers develop mouse model that reproduces most typical features of Noonan syndrome

Noonan syndrome is a rare disease that is characterised by a set of pathologies, including heart, facial and skeletal alterations, pulmonary stenosis, short stature, and a greater incidence of haematological problems (mainly juvenile myeloid leukaemia, or childhood leukaemia).

New research suggests that brain aging can be postponed if placed on a high-fat diet

New Danish-led research suggests that signs of brain aging can be postponed in mice if placed on a high-fat diet. In the long term, this opens the possibility of treatment of children suffering from premature aging and patients with Alzheimer's and Parkinson's disease. The research project is headed by the Center for Healthy Aging, University of Copenhagen and the National Institute of Health.

Effects of unhealthy lifestyle persist even after atherosclerosis treatment

Almost everyone knows that improving your eating habits will most likely improve your health. What most people may not know, however, is that the effects of poor eating habits persist long after dietary habits are improved. In a new report appearing in the November 2014 issue of the Journal of Leukocyte Biology, scientists use mice to show that even after successful treatment of atherosclerosis (including lowering of blood cholesterol and a change in dietary habits) the effects of an unhealthy lifestyle still affect the way the immune system functions.

Research findings could pave way for new treatments against filoviruses

Filoviruses like Ebola "edit" genetic material as they invade their hosts, according to a study published this week in mBio, the online open-access journal of the American Society for Microbiology.
