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).

Fructose common in western diet can damage brain genes

A range of diseases -- from diabetes to cardiovascular disease, and from Alzheimer's disease to attention deficit hyperactivity disorder -- are linked to changes to genes in the brain. A new study by UCLA life scientists has found that hundreds of those genes can be damaged by fructose, a sugar that's common in the Western diet, in a way that could lead to those diseases.

First breakthrough in gene therapy against aging

In September 2015, then 44 year-old CEO of BioViva USA Inc. Elizabeth Parrish received two of her own company's experimental gene therapies: one to protect against loss of muscle mass with age, another to battle stem cell depletion responsible for diverse age-related diseases and infirmities.

Researchers develop real-time single molecule electronic DNA sequencing platform

Researchers from Columbia University, with colleagues at Genia Technologies, Harvard University and the National Institute of Standards and Technology report achieving real-time single molecule electronic DNA sequencing at single-base resolution using a protein nanopore array.

NASA's research program uses omics to look more closely at individual health

NASA's Human Research Program is releasing the first half of a video series entitled Omics: Exploring Space Through You to highlight its Twins Study, in conjunction with its National DNA Day Reddit Ask Me Anything event at 10 a.m. CDT/11 a.m. EDT, Monday, April 25, 2016. The series explores space through you by using omics to look more closely at individual health.

Wellderly study finds link between cognitive decline genes and healthy aging

An eight-year-long accrual and analysis of the whole genome sequences of healthy elderly people, or "Wellderly," has revealed a higher-than-normal presence of genetic variants offering protection from cognitive decline, researchers from the Scripps Translational Science Institute (STSI) reported today in the journal Cell.

CUMC researchers identify new neurodevelopmental syndrome

A multicenter research team led by Columbia University Medical Center has discovered a new neurodevelopmental syndrome and the genetic mutations that cause it. The discovery is an important step toward creating targeted therapies for individuals with this syndrome, which causes severe developmental delays, abnormal muscle tone, seizures, and eye complications.

Researchers use highly accurate biomarker to measure aging in HIV infected patients

Thanks to combination antiretroviral therapies, many people with HIV can expect to live decades after being infected. Yet doctors have observed these patients often show signs of premature aging.

Subtle changes in protein-coding gene may cause different genetic disorders

It has been disorienting to the scientific and medical community as to why different subtle changes in a protein-coding gene causes many different genetic disorders in different patients -- including premature aging, nerve problems, heart problems and muscle problems. no other gene works like this. According to a new study, co-authored by Binghamton University faculty Eric Hoffman, it has to do with cell "commitment."

Scientists develop CRISPRainbow to study genome structure in real time

CRISPRainbow, a new technology using CRISPR/Cas9 developed by scientists at UMass Medical School, allows researchers to tag and track up to seven different genomic locations in live cells. This labeling system, details of which were published in Nature Biotechnology, will be an invaluable tool for studying the structure of the genome in real time.

Scientists identify transposable element in certain bird genomes

In rare instances, DNA is known to have jumped from one species to another. If a parasite's DNA jumps to its host's genome, it could leave evidence of that parasitic interaction that could be found millions of years later -- a DNA 'fossil' of sorts.

Scientists map core genes involved during DNA uptake in strep bacteria

Bacteria possess the ability to take up DNA from their environment, a skill that enables them to acquire new genes for antibiotic resistance or to escape the immune response. Scientists have now mapped the core set of genes that are consistently controlled during DNA uptake in strep bacteria, and they hope the finding will allow them to cut off the microbes' ability to survive what doctors and nature can throw at them.

Researchers find new insights on disease stages for gastric cancer patients

Diagnosis of gastric cancer in the early stages is difficult because of the lack of simple and cheap methods of inspection and specific markers of gastric cancer while the symptoms of the disease are vague and tend to overlap with other common and benign conditions. Better tumor characterization and more individualized treatment planning can be expected only with the implementation of better diagnostic tools combined with advances in molecular and genetic analysis.

Nivolumab drug shows survival benefit in phase III trial of patients with head and neck cancer

The immunotherapy drug nivolumab has become the first to show a survival benefit in head and neck cancer, after a major international trial found that it was more effective than standard chemotherapy.

Actin filaments may be key to molecular machinery that forms, stores long-term memories

Thank the little "muscles" in your neurons for allowing you to remember where you live, what your friends and family look like and a lot more.

Newly discovered player in epigenetic regulation closely linked to known cancer promoters

If genes form the body's blueprint, then the layer of epigenetics decides which parts of the plan get built. Unfortunately, many cancers hijack epigenetics to modulate the expression of genes, thus promoting cancer growth and survival.

Scientists discover new diagnostic marker for liver cancer

Scientists may have discovered a significant new diagnostic marker for liver cancer, according to a paper published in the April 18 online issue of Nature Cell Biology.

UNC scientists develop new optogenetic tool to study function of different proteins

Scientists at the University of North Carolina School of Medicine have developed a way to embed light-responsive switches into proteins so that researchers can use lasers to manipulate protein movement and activity within living cells and animals.

Researchers develop new method for identifying DNA mutations in single cancer cell

Researchers at The University of Texas MD Anderson Cancer Center have announced a new method for detecting DNA mutations in a single cancer cell versus current technology that analyzes millions of cells which they believe could have important applications for cancer diagnosis and treatment. The results are published in the April 18 online issue of Nature Methods.

Oxidized mitochondrial nucleoids released from neutrophils may contribute to SLE pathogenesis

Researchers at the Baylor Institute for Immunology Research have discovered that the neutrophils of systemic lupus erythematosus (SLE) patients release oxidized DNA from their mitochondria that can stimulate an unwanted immune response.
