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).

Micronics receives two new patents on microfluidic technologies

Micronics, Inc. today announced that it has been issued two patents from the United States Patent and Trademark Office (USPTO) for novel microfluidic devices and methods. These new patents relate to the company’s focus on the development of rapid and easy to use clinical diagnostic products.

Sequencing thousand and one genomes

Researchers at the Max Planck Institute for Developmental Biology in Tuebingen, Germany, reported the completion of the first genomes of wild strains of the flowering plant Arabidopsis thaliana. The entire genomes of two individuals of this species, one from Ireland, the other from Japan, have now been compared in great detail. They were found to be astonishingly different from each other, as Detlef Weigel and his colleagues write in Genome Research.

Existing anti-obesity drugs may be effective against flu, hepatitis and HIV

Viruses dramatically increase cellular metabolism, and existing anti-obesity drugs may represent a new way to block these metabolic changes and inhibit viral infection, according to a study published today in the journal Nature Biotechnology.

New way to control protein activity could lead to cancer therapies

Investigators at the Stanford University School of Medicine have found a way to quickly and reversibly fine-tune the activity of individual proteins in cells and living mammals, providing a powerful new laboratory tool for identifying - more precisely than ever before - the functions of different proteins.

Gene variant boosts risk of fatty liver disease

Researchers at UT Southwestern Medical Center have found that individuals who carry a specific form of the gene PNPLA3 have more fat in their livers and a greater risk of developing liver inflammation.

Genetic fishing expedition yields surprising catch important to mammals

Johns Hopkins investigators report the discovery of master controllers of a gene critical to human and all mammalian development by trawling, implausibly enough, through anonymous genetic sequences using tiny zebrafish embryos.

New drug might make tumor cells more sensitive to therapy

Scientists at St. Jude Children's Research Hospital have shown that it might be possible to make tumor cells more sensitive to irradiation and some types of chemotherapy by treating them with a drug that cripples their ability to repair DNA damage caused by these therapies.

DNA vaccine developed at the Karmanos Cancer Institute fights HER2-positive cancers

Researchers at the Barbara Ann Karmanos Cancer Institute and Wayne State University School of Medicine have developed a HER2 DNA vaccine that has shown to be effective on drug resistant tumors in mice. The study was reported in the September 15 issue of Cancer Research, a journal of the American Association for Cancer Research.
