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 use mouse model to better understand mechanism involved in atrial fibrillation

Atrial fibrillation is the most common heart arrhythmia in humans. This condition increases the risk of heart failure, stroke, dementia and death, and current treatments have suboptimal efficacy and carry side effects.

Discovery about DNA-reeling bacteria can help inform strategies to stop bacterial infection

A new study from Indiana University has revealed a previously unknown role a protein plays in helping bacteria reel in DNA in their environment -- like a fisherman pulling up a catch from the ocean.

Neutrophil extracellular traps could cause organ damage in malaria

Malaria is one of the world's deadliest infectious diseases: a small mosquito bite delivers numerous malaria parasites into the bloodstream. The human body defends itself valiantly against the parasite, which usually results in periodic flu-like symptoms and severe fever. Severe cases of the disease are accompanied by tissue damage and result in potentially fatal organ failure.

Simple blood test can better identify patients at risk of relapse for B-cell lymphoma

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma, a cancer that begins in certain immune system cells and can occur almost anywhere in the body. More than 28,000 people are diagnosed with DLBCL each year.

NCATS funds 'All of Us Research Program' to evaluate innovative DNA sequencing tools

The All of Us Research Program has selected the HudsonAlpha Institute for Biotechnology, Huntsville, Alabama, to evaluate the use of leading-edge DNA sequencing technologies that could someday improve diagnosis and treatment of many diseases, both common and rare.

Development and assessment of NGS-based microsatellite instability assay

The assay has a clinically relevant five-day turnaround time and can be conducted on as little as 20 ng genomic DNA with a batch size of up to forty samples in a single run.

Researchers develop new cheap method to identify aggressive tumors

Researchers at Karolinska Institutet in Sweden have developed a new cheap method that can identify highly heterogeneous tumors that tend to be very aggressive, and therefore need to be treated more aggressively. The technique is presented in the scientific journal Nature Communications.

Researchers uncover novel molecular clues for tumor aggression in neurofibromatosis type 1

Researchers at the Johns Hopkins Kimmel Cancer Center report that their study of tumor samples from people with the rare genetic syndrome neurofibromatosis type 1 (NF1) has uncovered novel molecular clues about which tumors are most likely to be aggressive in those with NF1

Yale scientists build powerful genomic research platform to study cervical cancer

Yale Cancer Center scientists have built a powerful genomic research platform to study cervical cancer, a disease that often is untreatable if it progresses after surgery or primary chemo-radiation treatment.

Father’s nutritional pattern affects child’s cardiovascular health

While couples often change their lifestyle in order to conceive faster, including crash diets, a new study in mice throws up the possibility that this kind of extreme dietary modification by the father might result in adverse effects on the child conceived in this manner.

Vaping helps 50,000 cigarette smokers quit in England each year

Thousands of cigarette smokers have been able to quit in the UK by switching to e-cigarettes, also known as vapes, claims a new study published in the journal Addiction.

Leading children's hospitals to use multi-year federal grant to scale up genomics research collaboration

With a shared vision of accelerating genomic discovery and improving patient outcomes, leaders from Boston Children's Hospital, Children's Hospital of Philadelphia, and Cincinnati Children's Hospital came together in 2015 to form the Genomics Research and Innovation Network.

Scientists successfully create age-resistant mice with hyper-long telomeres

Researchers have shown that it is possible to extend the life of mice by generating hyper-long telomeres, without using any gene modifying technologies.

Genes remember having low social status in the past

A new study in monkeys, published on October 14, 2019, in the Proceedings of the National Academy of Sciences, shows that organisms at the bottom of the social hierarchy live shorter lives. Moreover, they experience more sickness, and may continue to experience health problems despite moving up later. Adverse experiences of social life continue to reflect in their genes much longer than the actual experience, in the form of changes in gene expression via altered gene regulation.

Measuring development in young children: the DNA clock

Scientists have come up with a new discovery that could transform our understanding of how childhood growth and development are measured – the DNA clock. The study, published in the Proceedings of the National Academy of Science, is the first paper to...

Skin's circadian clock is independent of the eyes or brain, study finds

Squids, octopuses, cuttlefish, amphibians, and chameleon lizards are among the animals that can change the color of their skin in a blink of an eye. They have photoreceptors in their skin that operate independently of their brain. The photoreceptors are part of a family of proteins known as opsins.

Epigenetic changes can lead to development of GISTs, other cancers

Most cases of gastrointestinal stromal tumor (GIST), a type of soft-tissue cancer (sarcoma), are caused by mutations in genes that can be effectively targeted with drugs that inhibit the activity of rogue cancer-promoting enzymes.
