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).

MI-ONCOSEQ program identifies NAB2-STAT6 fusion in solitary fibrous tumors

It started with a 44-year-old woman with solitary fibrous tumor, a rare cancer seen in only a few hundred people each year. By looking at the entire DNA from this one patient's tumor, researchers have found a genetic anomaly that provides an important clue to improving how this cancer is diagnosed and treated.

Research shows genetic factors increase risk of visceral leishmaniasis

A new study published in Nature Genetics last week shows that genetics likely influence whether an individual develops visceral leishmaniasis, a lethal form of the parasitic disease transmitted by sandflies, the New York Times reports.

Study identifies 24 new copy number variants linked with autism

University of Utah (the U) researchers, in collaboration with several groups from around the country, published a paper on Monday, Jan. 14, 2013, following one of the biggest studies of its kind, that extends our understanding of genes related to autism spectrum diseases (ASDs) and advances methods for early detection and treatment.

Experimental vaccine elicits antibodies that can protect against Ebola virus infection

Researchers at the National Institutes of Health (NIH) and Oregon Health & Science University (OHSU) have found that an experimental vaccine elicits antibodies that can protect nonhuman primates from Ebola virus infection.

Genetics researchers identify 25 additional copy number variations associated with autism

Genetics researchers have identified 25 additional copy number variations (CNVs)—missing or duplicated stretches of DNA—that occur in some patients with autism. These CNVs, say the researchers, are "high impact": although individually rare, each has a strong effect in raising an individual's risk for autism.

Aggressive breast cancer’s metastasis molecular switch identified

Scientists at Weill Cornell Medical College have discovered the molecular switch that allows aggressive triple negative breast cancer cells to grow the amoeba-like protrusions they need to crawl away from a primary tumor and metastasize throughout the body. Their findings, published in Cancer Cell, suggest a novel approach for developing agents to treat cancer once it has spread.

Sequencing-based test effectively detects many fetal genetic defects

Researchers have developed a new screening test that allows detection of fetal abnormalities in maternal blood by deep sequencing cell-free DNA extracted from plasma.

Human papillomavirus an etiologic factor in 6% of OCSCC cases

High-risk human papillomavirus is an etiologic factor in approximately 6% of cases of oral cavity squamous cell carcinoma, according to epidemiologic research.

‘PapGene’ test detects endometrial and ovarian cancers

Researchers have adapted the papanicolaou smear test currently used to detect cervical cancer so that it can be used to screen women for endometrial and ovarian cancers.

Repression of PTB protein in fibroblasts can convert pluripotent stem cells into functional neurons

Repression of a single protein in ordinary fibroblasts is sufficient to directly convert the cells - abundantly found in connective tissues - into functional neurons. The findings, which could have far-reaching implications for the development of new treatments for neurodegenerative diseases like Huntington's, Parkinson's and Alzheimer's, will be published online in advance of the January 17 issue of the journal Cell.

Cancer researchers solve mystery of how Chd5 protein exerts its beneficial effects

A team of cancer researchers at Cold Spring Harbor Laboratory (CSHL) has solved the mystery of how one of the most powerful of the body's natural tumor-suppressing proteins, called Chd5, exerts its beneficial effects.

Johns Hopkins develops PapGene test to diagnose ovarian and endometrial cancers

Using cervical fluid obtained during routine Pap tests, scientists at the Johns Hopkins Kimmel Cancer Center have developed a test to detect ovarian and endometrial cancers. In a pilot study, the "PapGene" test, which relies on genomic sequencing of cancer-specific mutations, accurately detected all 24 (100 percent) endometrial cancers and nine of 22 (41 percent) ovarian cancers. Results of the experiments are published in the Jan. 9 issue of the journal Science Translational Medicine.

UMDNJ develops rapid detection test for Exserhilum rostratum

A rapid detection test for Exserhilum rostratum, the fungus primarily responsible for 39 deaths among patients injected last year with a contaminated steroid medication, has been developed by a research team led by David S. Perlin, PhD, Executive Director of the Public Health Research Institute (PHRI) at the University of Medicine and Dentistry of New Jersey-New Jersey Medical School.

Link between environmental tobacco smoke and dementia syndromes

Passive smoking, also known as 'second-hand' smoke or environmental tobacco smoke (ETS), is known to cause serious cardiovascular and respiratory diseases, including coronary heart disease and lung cancer.

TSRI chemists develop new cell-marking method

Chemists at The Scripps Research Institute (TSRI) have found an easier way to perform one of the most fundamental tasks in molecular biology. Their new method allows scientists to add a marker to certain cells, so that these cells may be easily located and/or selected out from a larger cell population.

Several genes may control body-fat responses to fast-food diets

Researchers at UCLA say it's not just what you eat that makes those pants tighter - it's also genetics. In a new study, scientists discovered that body-fat responses to a typical fast-food diet are determined in large part by genetic factors, and they have identified several genes they say may control those responses.
