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).

Horse genome sequence assembled

The first draft of the horse genome sequence has been deposited in public databases and is freely available for use by biomedical and veterinary researchers around the globe, leaders of the international Horse Genome Sequencing Project announced today.

ViroPharma receives orphan drug designation for Maribavir

ViroPharma Incorporated today announced that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation for maribavir for prevention of cytomegalovirus (CMV) viremia and disease in the populations at-risk.

Single transcription factor GABP a major player in cell growth

When cells go about the business of dividing, they can get sidelined. Maybe there aren't enough nutrients. Maybe there aren't the right signals to resume multiplying. Either way, cells go quiet.

Human proteins evolving slowly thanks to multi-tasking genes

Many human proteins are not as good as they might be because the gene sequences that code for them have a double role which slows down the rate at which they evolve, according to new research published in PLoS Biology.

Selenium reduces prostate cancer risk in men taking extra vitamin E

A new study is suggesting that for certain groups of men a high dietary intake of selenium may reduce their risk of prostate cancer.

Scientists step closer to understanding the relationship between aging and cancer

Wielding a palette of chromosome paints, scientists at the Salk Institute for Biological Studies have taken a step closer to understanding the relationship between aging and cancer by visualizing chromosomes of cells from patients with a heritable premature aging disease known as Werner Syndrome.

Self-assembling nanostructures of DNA

Wouldn't it be great if we could get computer chips to grow on trees? Or at least use the specific bonds of DNA molecules to get nanostructures to grow themselves right in the test tube?

New type of nanoparticle created by spray pyrolysis

Researchers at the University of California, Davis, have created a new type of nanoparticle that could be used in tests for medical diagnostics, environmental pollution, and contamination of food products.

Scientists test technique for identifying newly recognized DNA variations that may influence disease risk

Rather than focus on errors and alterations in DNA sequence, the new technique highlights variations in the number of copies of a particular gene.

Nventa Bio issued U.S patent for heat shock protein fusion to treat influenza

The patent provides coverage for compositions of fusion proteins comprised of an influenza antigen fused to a heat shock protein (Hsp), as well as DNA encoding such fusion proteins and their use in immunotherapy.

Salmonella survives better due to altered DNA

Since 1995 there has been a considerable increase in the number of infections with a specific type of Salmonella bacteria transmitted via food.

Nanocarrier stimuli-activated gene delivery

One approach to developing tumor-specific drug delivery agents is to create nanomaterials that release a therapeutic payload only after reaching their intended target.

RNA used to turn on genes to alleviate disease

A new technique that employs RNA, a tiny chemical cousin of DNA, to turn on genes could lead to therapeutics for conditions in which nudging a gene awake would help alleviate disease, researchers at UT Southwestern Medical Center say.

Simple diagnostic test detects genetic signs of lung cancer in sputum

DNA coughed up along with phlegm could point to lung cancer, say researchers at the University of Maryland School of Medicine who are developing an inexpensive and non-invasive gene probe to help diagnose early stage lung cancer in current and former smokers.

Variations in SORL1 gene may factor in development of Alzheimer's disease

Variations in a gene known as SORL1 may be a factor in the development of late onset Alzheimer's disease, an international team of researchers has discovered. The genetic clue, which could lead to a better understanding of one cause of Alzheimer's, is reported in Nature Genetics online, and was supported in part by the National Institutes of Health (NIH).
