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).

Lack of adequate sleep can interfere with fundamental cellular process

Lack of adequate sleep can do more than just make you tired. It can short-circuit your system and interfere with a fundamental cellular process that drives physical growth, physiological adaptation and even brain activity, according to a new study from the University of Tennessee, Knoxville.

University of Kansas professor recognized with MERIT Award

Emily Scott, professor of medicinal chemistry at the University of Kansas, has been recognized with a MERIT Award from the National Institutes of Health's National Institute of General Medical Sciences. It's a rare and important recognition -- researchers can receive them only once in a career.

Mayo Clinic cancer experts find gaps in current colorectal cancer screening approaches

Colorectal cancer remains the second leading cause of cancer death for men and women combined in the U.S. The goal of screening is to reduce the number of people who die from this common cancer. According to Mayo Clinic cancer experts there are gaps in current screening approaches in terms of detection accuracy, patient willingness to use them, and accessibility.

New online tool may allow researchers explore formation of hair follicles

A new online database will empower researchers exploring how hair follicles and the surrounding skin develop, according to an article published recently in the journal Developmental Cell. The work is central to understanding the interactions between stem cells and their environment - or "niche cells" - during fetal development, and will specifically facilitate future attempts to make skin grafts with functional hair follicles or to regenerate lost hair in patients.

Study reports discovery of new class of DNA repair enzyme

This year's Nobel Prize in chemistry was given to three scientists who each focused on one piece of the DNA repair puzzle. Now a new study, reported online Oct. 28 in the journal Nature, reports the discovery of a new class of DNA repair enzyme.

New clinical trial on breast cancer may help treat and control disease

A new clinical trial at Sanford Health is exploring how genetic changes that occur during breast cancer might help health care providers better identify, treat and control the disease.

Study reveals mechanism behind protein-related diseases

Dartmouth researchers have found that some proteins turn into liquid droplets on the way to becoming toxic solids implicated in neurodegenerative diseases and other genetic disorders.

SLU VTEU awarded $5.8 million NIH contract to support 'omics' research initiative

Saint Louis University's Vaccine and Treatment Evaluation Unit has received a five-year, $5.8 million contract from the National Institutes of Health to support an "omics" research initiative to study the safety and effectiveness of vaccines and other ways to fight infectious diseases.

Certain drugs could be used to treat gastric cancers with particular pattern of mutations

Gastric cancer, otherwise known as stomach cancer, does not respond well to existing treatments and it is currently the third leading cause of cancer death in the world (after lung and liver cancer). Researchers have discovered that certain drugs, currently used to treat breast, ovarian and pancreatic cancers, could also be used to treat certain gastric cancers with a particular pattern of mutations (genomic molecular fingerprint).

New research shows that autophagy can operate in cell nucleus to guard against start of cancer

Autophagy, literally self-eating or the degradation of unwanted cellular bits and pieces by the cell itself, has been shown for the first time to also work in the cell nucleus. In addition, in this setting it plays a role in guarding against the start of cancer, according to new research from the Perelman School of Medicine at the University of Pennsylvania.

IDT’s innovative Alt-R CRISPR-Cas9 System improves genome editing potency, reduces cell toxicity

Integrated DNA Technologies, introduces a new approach to CRISPR—its innovative Alt-R CRISPR-Cas9 System, based on the naturally occurring S. pyogenes CRISPR RNA system.

UAB researcher awarded NIH grant to study pathogenesis of thrombotic microangiopathy

University of Alabama at Birmingham researcher X. Long Zheng, M.D., Ph.D., has received a five-year, $2.5 million National Institutes of Health grant to study the pathogenesis of thrombotic microangiopathy, or TMA. In simple terms, this means looking for factors that cause or aid the onset of extensive microscopic clots in small blood vessels throughout the body. Though tiny, these spots can damage kidneys, heart and brain, and they can cause death.

New paper device could rapidly and inexpensively assess hepatitis B, male infertility

Scientists have developed a new paper device that analyzes DNA and could rapidly and inexpensively assess disparate conditions including hepatitis B and male infertility, which together affect millions of people around the world. The test, reported in the Journal of the American Chemical Society, could be of particular help diagnosing people in low-income areas.

Researchers identify inherited gene variation associated with pediatric acute lymphoblastic leukemia

Researchers studying two generations of a family affected by pediatric acute lymphoblastic leukemia (ALL) have identified an inherited variation in the ETV6 gene that is associated with an increased risk of developing the disease. St. Jude Children's Research Hospital investigators led the study, which appears in the October 28 issue of the journal Lancet Oncology.

Researchers identify role of cGAS enzyme in autoimmune diseases

Activating an enzyme that sounds an alarm for the body's innate immune system causes two lethal autoimmune diseases in mice, while inhibiting the same enzyme rescues them, UT Southwestern Medical Center researchers report.

Study uncovers new genetic variants linked to increased risk of testicular cancer

A new study of more than 25,000 men has uncovered four new genetic variants associated with increased risk of testicular cancer.

Experts reveal link between excess body weight and colorectal cancer risk

Experts speaking at the 23rd United European Gastroenterology Week (UEG Week 2015) in Barcelona, Spain today revealed compelling evidence of the link between excess body weight and risk of colorectal cancer (CRC). John Mathers, Professor of Human Nutrition from the Institute of Cellular Medicine at Newcastle University in the UK presented data showing an overall increase of 18% in relative risk of CRC per 5 unit increase in BMI.

Four microRNAs appear to play critical roles in controlling cholesterol, triglyceride metabolism

Four tiny segments of RNA appear to play critical roles in controlling cholesterol and triglyceride metabolism. In their report receiving advance online publication in Nature Medicine, a Massachusetts General Hospital-based research team describes finding how these microRNAs could reduce the expression of proteins playing key roles in the generation of beneficial HDL cholesterol, the disposal of artery-clogging LDL cholesterol, control of triglyceride levels and other risk factors of cardiovascular disease.

Researchers develop multiplexed screening approach to study cancer development in mice

In a novel use of the CRISPR/Cas9 system, which can be deployed to switch genes off, researchers from Germany, the UK and Spain have developed a multiplexed screening approach to study and model cancer development in mice. The scientists mutated genes in the adult mouse liver uncovering their cancer-causing roles and determining which combinations of genes cooperate to cause liver cancer.

UTMB researchers find mechanisms to determine when pregnant women go into labor

During the last few weeks of a woman's pregnancy, many keep an overnight bag ready to go at a moment's notice in case they begin to go into labor. They do this because there is no clear signal that labor is about to begin - before the body makes it abundantly clear that this process has started. Understanding the mechanisms that initiate this process is especially important when treating women at risk of going into labor early.
