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).

Study identifies abnormal brain gene expression patterns in autism

A study led by Eric Courchesne, PhD, director of the Autism Center of Excellence at the University of California, San Diego School of Medicine has, for the first time, identified in young autism patients genetic mechanisms involved in abnormal early brain development and overgrowth that occurs in the disorder. The findings suggest novel genetic and molecular targets that could lead to discoveries of new prevention strategies and treatment for the disorder.

WCI technique uses MRS to detect oncometabolites

Researchers at Winship Cancer Institute have developed a technique for detecting an "oncometabolite", a chemical produced by some brain tumors' warped metabolism, via non-invasive imaging.

GUCY2C gene mutation leads to familial diarrhea syndrome

When the intestines are not able to properly process our diet, a variety of disorders can develop, with chronic diarrhea as a common symptom. Chronic diarrhea can also be inherited, most commonly through conditions with genetic components such as irritable bowel syndrome. Researchers in Norway, India, and at the HudsonAlpha Institute for Biotechnology have identified one heritable DNA mutation that leads to chronic diarrhea and bowel inflammation.

Researchers explain how obscurins suppress breast cancer formation

A new discovery published online in The FASEB Journal may lead to a new tool to help physicians assess breast cancer risk as well as diagnose the disease. In the report, researchers from Johns Hopkins University and the University of Maryland, explain how proteins, called "obscurins," once believed to only be in muscle cells, act as "tumor suppressor genes" in the breast.

Scientists create worm model of back-up telomere repair strategy

Rapidly dividing cancer cells are skilled at patching up damage that would stop normal cells in their tracks, including wear and tear of telomeres, the protective caps at the end of each chromosome.

Meditation improves ability to cope with stress and increases telomerase activity

Calmly meditating produces exciting, beneficial effects on your body. It can protect your DNA against cancer-promoting genetic developments and free you from everyday stresses and distractions. That's why meditation is one of the most powerful, but often neglected, tools for maintaining optimal health.

New drug makes chemotherapy more effective in treating acute myeloid leukemia

Doctors at Washington University School of Medicine in St. Louis have shown that a new drug makes chemotherapy more effective in treating acute myeloid leukemia, a cancer of the white blood cells. Instead of attacking these cells directly, the drug helps drive them out of the bone marrow and into the bloodstream, where they are more vulnerable to chemotherapy.

Mayo Clinic researchers train mouse immune systems to eradicate skin cancer from within

Mayo Clinic researchers have trained mouse immune systems to eradicate skin cancer from within, using a genetic combination of human DNA from melanoma cells and a cousin of the rabies virus. The strategy, called cancer immunotherapy, uses a genetically engineered version of the vesicular stomatitis virus to deliver a broad spectrum of genes derived from melanoma cancer cells directly into tumors.

Study identifies new hypervariable regions in human gut viruses

A growing body of evidence underscores the importance of human gut bacteria in modulating human health, metabolism, and disease. Yet bacteria are only part of the story. Viruses that infect those bacteria also shape who we are. Frederic D. Bushman, PhD, professor of Microbiology at the Perelman School of Medicine at the University of Pennsylvania, led a study published this month in the Proceedings of the National Academy of Sciences that sequenced the DNA of viruses -- the virome -- present in the gut of healthy people.
