DNA News and Research

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).

Scientists discover new genetic variants, pave way for early detection of ovarian cancer

An international consortium of scientists has discovered new genetic variants in five regions of the genome that affect the risk of ovarian cancer in the general population, according to two separate studies published today (Sunday), online in Nature Genetics.

Penn study reveals structure of cell division's key molecule

On average, one hundred billion cells in the human body divide over the course of a day. Most of the time the body gets it right but sometimes, problems in cell replication can lead to abnormalities in chromosomes resulting in many types of disorders, from cancer to Down Syndrome.

APC gene mutation affects DNA methylation in colon cancer: Research

Colon cancer is the second most common cancer in the United States and causes more than 50,000 deaths each year. It has been known for some time that mutations in the APC gene occur in more than 85 percent of all sporadic colon cancers. Now researchers at Huntsman Cancer Institute at the University of Utah demonstrate in a study featured today in Cell the mechanism by which mutation of the APC gene affects a cellular process known as DNA methylation.

Researchers discover evolutionary nature of bacteria to spread chronic infectious disease

Researchers from the Center for Genomic Sciences at Allegheny General Hospital (AGH) in Pittsburgh have made a landmark discovery about the evolutionary nature of bacteria in the setting of chronic infectious disease. Reporting today in the journal PLos Pathogens, the AGH team documents for the first time that bacteria engage in a process called horizontal gene transfer to evolve rapidly during the course of a single infection.

Conference to discuss frontline of immunological research, its clinical application

The immune system is evolved to protect our body against a variety of infectious agents which can cause serious and often fatal diseases. We now appreciate that the immune system is also involved in surveillance of malignant transformation of normal cells that constitute our body, as well as rejection of transplanted organs.

Blood vessel growth promoting microRNA predicts diabetes: Study

For the first time, scientists have found that blood levels of some ribonucleic acids (microRNAs) are different among people with type 2 diabetes and those who subsequently develop the disease compared to healthy controls, according to research reported in Circulation Research: Journal of the American Heart Association.

Global regulator for DNA trade needed

Amid growing concern that synthetic life sciences pose biosecurity and biosafety risks, scrutiny is increasing into the burgeoning DNA sequence trade. Research published today in the Bulletin of the Atomic Scientists, published by SAGE, looks at the necessity of a global regulator for DNA trade, and the significant barriers to creating one.

New genetic analysis technique isolates culprit gene in families with inherited single-gene kidney diseases

A University of Michigan-led research team has identified a gene responsible in some families for a devastating inherited kidney disorder, thanks to a new, faster method of genetic analysis not available even two years ago. The success offers hope that scientists can speed the painstaking search for the genes responsible for many rare diseases and test drugs to treat them.

Simian immunodeficiency virus is at least 32,000 to 75,000 years old

An ancestor of HIV that infects monkeys is thousands of years older than previously thought, suggesting that HIV, which causes AIDS, is not likely to stop killing humans anytime soon, finds a study by University of Arizona and Tulane University researchers.

Myrexis to present poster on cancer metabolism inhibitor program

Myrexis, Inc., a biotechnology company focused on discovering, developing, and commercializing novel treatments for cancer, today announced it will present a poster at the Cancer and Metabolism: Pathways to the Future meeting in Edinburgh, Scotland, as well as two additional posters at the 22nd European Organisation for Research and Treatment of Cancer (EORTC), National Cancer Institute (NCI) and American Association for Cancer Research (AACR) Symposium on "Molecular Targets and Cancer Therapeutics" November 16-19, 2010, in Berlin, Germany.

Researchers decode key DNA in evolution of aging, development and fertility

UC Irvine researchers have deciphered how lowly fruit flies bred to rapidly develop and reproduce actually evolve over time. The findings, reported in the Sept. 15 online issue of Nature, contradict the long-held belief that sexual beings evolve the same way simpler organisms do and could fundamentally alter the direction of genetic research for new pharmaceuticals and other products.

Generex presents Ii-Key hybrids product development at Gene based Vaccines conference

Generex Biotechnology Corporation today announced presentations in respect of the technologies and development products of its wholly-owned subsidiary, Antigen Express, Inc. The presentations were made at the conference Gene based Vaccines: Optimizing Development and Delivery 2010 held September 13 and 14, 2010 in Vienna, Austria and at the Immunotherapeutics and Vaccine Summit held in Cambridge, MA from August 17-19, 2010.

Scripps Research Institute receives grant to develop DNA sequencing technology

Scripps Research Institute Professor Reza Ghadiri, Ph.D., has been awarded a four-year, $5.1 million grant as part of a National Institutes of Health (NIH) initiative to spur the development of the next generation of DNA sequencing technologies, which could enable biomedical researchers and health care workers to routinely sequence a person's DNA.

Researcher discover enzyme for brain tumor malignancy

Tom Wurdinger, a Dutch researcher who is connected to Harvard (Boston) and the VUmc Cancer Center in Amsterdam, has discovered the enzyme playing a very important role in the return of malign brain tumor after surgery and radiation. By making this enzyme inactive, the cancer cell can become disorganized and blow itself up.

Devil genome sequenced: Hope for endangered Tasmanian Devils

Tasmanian Devil Salem died at age seven but made a difference to her endangered species. Only 50 micrograms of her tissue was taken and processed by Australian genetic scientist Elizabeth Murchison, using new US technology, to produce the first devil genome sequence. As a result, the fight against devil facial tumor disease now has a draft DNA reference map. This was presented at a genetic conference in Hobart yesterday.

Scientists discover 13 genes linked to human body mass

Johns Hopkins scientists who specialize in unconventional hunts for genetic information outside nuclear DNA sequences have bagged a weighty quarry 13 genes linked to human body mass. The experiments screened the so called epigenome for key information that cells remember other than the DNA code itself and may have serious implications for preventing and treating obesity, the investigators say.
