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).

BCCA, UBC scientists identify new breast cancer genes

Scientists at the BC Cancer Agency and University of British Columbia have identified new breast cancer genes that could change the way the disease is diagnosed and form the basis of next-generation treatments.

Brain size and IQ secret may lie in genes: Study

The study, conducted by a team of more than 200 scientists from 100 institutions worldwide, measured the size of the brain and its memory centers in thousands of MRI images from 21,151 healthy people while simultaneously screening their DNA. According to the researchers, a variant in a gene called HMGA2 affected the brain size, as well as a person's intelligence.

Caffeine increases eye's ability to produce tears

Researchers at the University of Tokyo's School of Medicine have shown for the first time that caffeine intake can significantly increase the eye's ability to produce tears, a finding that could improve treatment of dry eye syndrome. This common eye condition affects about four million people age 50 and older in the United States.

Allied Healthcare announces Coridon license to vector technology

Allied Healthcare Group (ASX: AHZ) has announced an update on the progress of Coridon, its investment company founded by Professor Ian Frazer and working on developing the next generation of vaccines. Included in these activities, Cordon has entered into a license agreement with Nature Technology Corporation (NTC) and has contracted VGXI Inc. in the US for production of clinical material for the Phase I study scheduled to begin later this year.

More insight into tangled proteins in Alzheimer's disease

In Alzheimer's disease, brain neurons become clogged with tangled proteins. Scientists suspect these tangles arise partly due to malfunctions in a little-known regulatory system within cells. Now, researchers have dramatically increased what they know about this particular regulatory system in mice. Such information will help scientists better understand Alzheimer's and other diseases in humans and could eventually provide new targets for therapies.

Individuals with low-quality genes may produce offspring with even more inferior chromosomes

Evolutionary biologists at the University of Toronto have found that individuals with low-quality genes may produce offspring with even more inferior chromosomes, possibly leading to the extinction of certain species over generations.

UCSF scientists assemble high-value genetic resource to help researchers

One of the ultimate ways of understanding what impact any particular gene has in human health or disease is to disrupt it-knocking it down or wiping it out in a worm, fly or mouse and gauging what happens next. Now scientists at the University of California, San Francisco (UCSF) Diabetes Center and the Gladstone Institute for Cardiovascular Disease have assembled a large publicly available resource to help researchers determine the importance of genes in mice and better gauge what roles they might play in disease.

FDA grants 510(k) clearance for QIAGEN’s molecular detection PCR technology

QIAGEN N.V. today announced that the U.S. Food and Drug Administration (FDA) has granted two 510(k) clearances for its real-time PCR (polymerase chain reaction) instrument Rotor-Gene Q MDx and a compatible test for the detection of Influenza A/B, the artus Infl A/B RG RT-PCR Kit, for in vitro diagnostic use.

Two related enzymes play a key role in development of T-ALL

Columbia University Medical Center (CUMC) scientists have demonstrated that two related enzymes - phosphoinositide-3 kinase (PI3K) gamma and delta - play a key role in the development of T-cell acute lymphoblastic leukemia (T-ALL), a highly aggressive childhood leukemia that is difficult to treat.

Genes linked to major brain functions and disorders

An international team of researchers have found the genes that increase or reduce the risk of certain mental illnesses and Alzheimer's disease. They claim that some genes that may explain individual differences in brain size and intelligence as well. The team of more than 200 scientists at 100 institutions said this was the largest-ever brain study to date.

Gene function preserved despite structural differences in the DNA

Chloroplasts, the plant cell's green solar power generators, were once living beings in their own right. This changed about one billion years ago, when they were swallowed up but not digested by larger cells. Since then, they have lost much of their autonomy.

$Researchers identify 32 genetic regions associated with osteoporosis, fracture$

Researchers identify 32 genetic regions associated with osteoporosis, fracture

Thirty-two previously unidentified genetic regions associated with osteoporosis and fracture have been identified by a large, worldwide consortium of researchers, including Stanford Prevention Research Center chief John Ioannidis, MD, DSc. Variations in the DNA sequences in these regions confer either risk or protection from the bone-weakening disease. Many, but not all, of the regions encode proteins involved in pathways known to involve bone health.
