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 reveal how C. difficile wreaks havoc on guts, causes life-threatening diseases

In a new paper in the journal Infection and Immunity, the researchers lay out for the first time exactly how C. difficile wreaks havoc on the guts of animals in a short time, and causes severe diarrhea and life-threatening disease in humans.

Research findings could someday lead to new treatments for patients with autism and cancer

In recent years, scientists have found a surprising a connection between some people with autism and certain cancer patients: They have mutations in the same gene, one that codes for a protein critical for normal cellular health. Now scientists have reported in the ACS journal Biochemistry that the defects reduce the activity and stability of the protein.

Study provides new insights into early events that shape cancer

A study led by researchers from Brigham and Women's Hospital suggests a new way to trace cancer back to its cell type of origin. By leveraging the epigenome maps produced by the Roadmap Epigenomics Program - a resource of data collected from over 100 cell types - the research team found that the unique genetic landscape of a particular tumor could be used to predict that tumor's cell type of origin.

UT Dallas study reports new gene therapy approach

Bioengineers at The University of Texas at Dallas have created a novel gene-delivery system that shuttles a gene into a cell, but only for a temporary stay, providing a potential new gene-therapy strategy for treating disease.

Nicotine metabolite supports learning, memory by amplifying action of primary chemical messenger

Nicotine's primary metabolite supports learning and memory by amplifying the action of a primary chemical messenger involved in both, researchers report.

Study findings could lead to new potential drug targets for allergic diseases

Scientists have discovered over 30 new genes that predispose people to allergies and asthma, some of which could be targets for new drugs.

Duke researchers demonstrate genetic therapeutic technique to treat DMD patients

Duke researchers have demonstrated a genetic therapeutic technique that has the potential to treat more than half of the patients suffering from Duchenne Muscular Dystrophy (DMD).

Researchers assemble comprehensive map of human epigenome

Virtually every cell in the body carries an identical genome. But how is it possible that each of the body's 200 different types of specialized cells - in the heart, brain, bone, skin and elsewhere - develops from the same DNA instruction book?

Epigenome may hold promise for conquering diseases

The human genome project captured the public imagination when its first draft was published 14 years ago this week in the international science journal Nature, but the epigenome may hold the real promise for conquering disease.

New facts provide baseline for future studies of epigenome's role in human development, diseases

While genomics is the study of all of the genes in a cell or organism, epigenomics is the study of all the genomic add-ons and changes that influence gene expression but aren't encoded in the DNA sequence. A variety of new epigenomic information is now available in a collection of studies published Feb. 19 in Nature by the National Institutes of Health Roadmap Epigenomics Program.

UCSD researchers make new attempt to develop malaria vaccine candidate

Researchers at University of California, San Diego School of Medicine used algae as a mini-factory to produce a malaria parasite protein. The algae-produced protein, paired with an immune-boosting cocktail suitable for use in humans, generated antibodies in mice that nearly eliminated mosquito infection by the malaria parasite.

Lupus Research Institute announces this year's Novel Research Grants

As the Lupus Research Institute celebrates its 15th anniversary, the engine of innovation moves forward at accelerated speed with the announcement of this year's Novel Research Grants bringing new talent from a wide diversity of specialties. Each project lives up to the strictest definition of novel – wholly original, never-been-done-before.

TDF monotherapy ‘reasonable’ option in entecavir-resistant HBV

Researchers from the Republic of Korea have found that the efficacy of tenofovir disoproxil fumarate monotherapy is comparable to that of TDF plus entecavir in chronic hepatitis B patients with genotypic resistance to entecavir.

Long-term TDF ‘promising’ in Chinese HBV patients after multiple antiviral failures

Long-term tenofovir disoproxil fumarate therapy is effective in Chinese patients with chronic hepatitis B virus infection who have relapsed after treatment with multiple nucleos(t)ide analogues, research suggests.

First comprehensive maps and analyses of human epigenomes revealed

Two dozen scientific papers published online simultaneously on Feb. 18, 2015 present the first comprehensive maps and analyses of the epigenomes of a wide array of human cell and tissue types. Epigenomes are patterns of chemical annotations to the genome that determine whether, how, and when genes are activated.

Facts about precision medicine

President Barack Obama is requesting an increase of $215 million in the 2016 federal budget to launch the Precision Medicine Initiative. This boost in funding for research will give genetic causes of cancer a national focus specifically around precision or "personalized" treatments for cancer in the future.

Fetal exposure to drugs can cause neurological problems

Research suggests that fetal exposure to chemicals or drugs can cause neurological problems. Babies whose mothers take the epilepsy drug valporic acid (VPA) during pregnancy, for example, appear to have an elevated risk of developing an autism spectrum disorder.
