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).

Research study to determine association of CYP2D6 variation with tamoxifen therapy

Among women with early stage breast cancer, genetic variation of a certain enzyme appears to be associated with clinical outcomes for women treated with tamoxifen, according to a study in the October 7 issue of JAMA.

Study reveals large structural differences between natural prions and man-made synthetic analogs

A collaboration between scientists at Vanderbilt University and the University of California, San Francisco has led to the first direct information about the molecular structure of prions. In addition, the study has revealed surprisingly large structural differences between natural prions and the closest synthetic analogs that scientists have created in the lab.

Scientists develop new molecule that can deliver genetic-based drugs into cells

Theresa M. Reineke, associate professor of chemistry in the College of Science, and colleagues in her lab at Virginia Tech and at the University of Cincinnati have developed a new molecule that can travel into cells, deliver genetic cargo, and packs a beacon so scientists can follow its movements in living systems.

Call for new policies on access to biobanked children's DNA

Scientists look for clues about therapies and cures for life-threatening childhood illnesses in children's DNA -- it seems only logical to do so. But the decision as to who should have access to DNA samples from children provides a unique ethical conundrum, says a Tel Aviv University researcher in a recent publication for the esteemed journal Science, co-authored by colleagues from The Netherlands and Canada.

Researchers show that DNA methylation plays a crucial role for cancer stem cells

During cell division, whether hematopoietic stem cells (HSCs) will develop into new stem cells (self-renewal) or differentiate into other blood cells depends on a chemical process called DNA methylation.

AOAC Research Institute certifies Idaho's E.coli O157:H7 test

Idaho Technology, Inc. (ITI) has been granted Performance Tested Methods Status by the AOAC Research Institute (Certificate No. 100901) for its E.coli O157:H7 test used with the R.A.P.I.D.® LT Food Security System (FSS). The assay uses real-time PCR technology to identify the presence of E.coli O157:H7 in raw ground beef and uncooked spinach food samples.

Gene mutation linked to age-related hearing loss

Patients who exhibited a certain genetic mutation of anti-oxidant enzymes are three times more likely to develop age-related hearing loss (ARHL), according to new research presented at the 2009 American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO, in San Diego, CA.

Hepatitis B Foundation calls for consistent monitoring and referral of HBV infected children

An expert panel of nationally recognized pediatric liver specialists convened by the Hepatitis B Foundation is calling for more consistent monitoring and referral of children chronically infected with the hepatitis B virus (HBV). The panel's recommendations for pediatricians and other primary care practitioners stress the need for routine monitoring of children with chronic HBV infections, and timely consultation with a pediatric liver specialist.

Researchers identify that KLF17 gene with Id1 gene can regulate breast cancer metastasis

Researchers at The Wistar Institute have identified a key gene (KLF17) involved in the spread of breast cancer throughout the body. They also demonstrated that expression of KLF17 together with another gene (Id1) known to regulate breast cancer metastasis accurately predicts whether the disease will spread to the lymph nodes.

Two-thirds of tonsil tumour samples show evidence of HPV-16 gene: Study

It is estimated that more than 7,000 people are diagnosed with head and neck cancer each year in the UK and approximately 3,500 cases result in death. These cancers include tumours of the mouth, lips, throat and voice-box, and some have been linked to the sexually transmitted infection, HPV-16. Scientists at Liverpool analysed the DNA of more than 90 cancerous tissue samples to look for genes that indicated infection.
