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).

Scientists receive NIH grants to explore sudden unexpected death in epilepsy

Nine groups of scientists will receive funding totaling $5.9 million in 2014 to work together on increasing the understanding of sudden unexpected death in epilepsy (SUDEP), the leading cause of death from epilepsy. The consortium becomes the second Center Without Walls, an initiative to speed the pace of research on difficult problems in epilepsy by promoting collaborative research.

Findings open new avenues for research to predict risk of therapy-related AML

For a small percentage of cancer patients, treatment aimed at curing the disease leads to a form of leukemia with a poor prognosis. Conventional thinking goes that chemotherapy and radiation therapy induce a barrage of damaging genetic mutations that kill cancer cells yet inadvertently spur the development of acute myeloid leukemia (AML), a blood cancer.

Researchers reveal that genetic mutations may cause more cases of ALS

Genetic mutations may cause more cases of amyotrophic lateral sclerosis (ALS) than scientists previously had realized, according to researchers at Washington University School of Medicine in St. Louis and Cedars-Sinai Medical Center in Los Angeles. The scientists also showed that the number of mutated genes influences the age when the fatal paralyzing disorder first appears.

Scientists suspect role of mini-chromosomes in cancers, diseases caused by gene mutations

Cancers are due to genetic aberrations in certain cells that gain the ability to divide indefinitely. This proliferation of sick cells generates tumors, which gradually invade healthy tissue. Therefore, current therapies essentially seek to destroy cancer cells to stop their proliferation. Through high-throughput genetic sequencing of glioblastoma cells, one of the most deadly brain tumors, a team of geneticists from the University of Geneva's (UNIGE) Faculty of Medicine discovered that some of these mutations are caused by supplemental extrachromosomal DNA fragments, called double minutes, which enable cancer cells to better adapt to their environment and therefore better resist to treatments meant to destroy them.

Genetics may play major role in Lou Gehrig's disease, study reveals

Genetics may play a larger role in causing Lou Gehrig's disease than previously believed, potentially accounting for more than one-third of all cases, according to one of the most comprehensive genetic studies to date of patients who suffer from the condition also known as amyotrophic lateral sclerosis, or ALS.

Promising anti-malarial compound uses novel mechanism to kill malaria parasite

An international research collaborative has determined that a promising anti-malarial compound tricks the immune system to rapidly destroy red blood cells infected with the malaria parasite but leave healthy cells unharmed. St. Jude Children's Research Hospital scientists led the study, which appears in the current online early edition of the Proceedings of the National Academy of Sciences.

Growth genes seem different in Hunger Winter children

Individuals conceived in the severe Dutch Famine, also called the Hunger Winter, may have adjusted to this horrendous period of World War II by making adaptations to how active their DNA is. Genes involved in growth and development were differentially regulated, according to researchers at the Leiden University Medical Center, Harvard University, and Columbia University's Mailman School of Public Health.

Scientists seek to improve stem cell transplant outcomes using DNA sequencing, mathematical modeling

Is the human immune system similar to the weather, a seemingly random yet dynamical system that can be modeled based on past conditions to predict future states? Scientists at VCU Massey Cancer Center's award-winning Bone Marrow Transplant (BMT) Program believe it is, and they recently published several studies that support the possibility of using next-generation DNA sequencing and mathematical modeling to not only understand the variability observed in clinical outcomes of stem cell transplantation, but also to provide a theoretical framework to make transplantation a possibility for more patients who do not have a related donor.
