This news release is available in German. In the majority of cases, the onset of cancer is characterised by a minor change in a person's genetic material. A cell's DNA mutates in a particular area to the extent that the cell no longer divides in a controlled manner, but begins to grow uncontrollably. In many cases, this type of genetic mutation involves chemical changes to individual building blocks of DNA. These changes are induced by smoking tobacco and consuming foods such as cured meats. This is because the contents of these materials can chemically react with and change building blocks of cellular DNA, thereby creating DNA adducts. Up to now, scientists have been able to determine whether gene samples contain adducts and if so, how many. However, the procedure is laborious and finding out exactly where a building block in the genetic code has been altered into an adduct has not been possible. Researchers from the team led by Shana Sturla, professor of Food and Nutrition Toxicology, have succeeded for the first time in amplifying gene samples containing DNA adducts while retaining references to these adducts. This type of amplification is a prerequisite for the majority of technologies used by … Continue reading →

There were no witnesses to the gruesome murder of a South Carolina mother and her 3-year-old daughter inside a busy apartment complex four years ago. But a new technology that can create an image of someone using DNA samples left at crime scenes might bring police closer to catching the killer. Reston, Va.-based Parabon Nanolabs, with funding from the Department of Defense, has debuted a breakthrough type of analysis called DNA phenotyping which the company says can predict a person's physical appearance from the tiniest DNA samples, like a speck of blood or strand of hair. The DNA phenotyping service, commercially known as "Snapshot," could put a face on millions of unsolved cases, including international ones, andgenerate investigative leads when the trail has gone cold. "This is particularly useful when there are no witnesses, no hits in the DNA database and nothing to go on," Dr. Ellen McRae Greytak, Parabon's director of bioinformatics, told FoxNews.com. - Dr. Ellen McRae Greytak, Parabon Nanolabs "Traditional forensic analysis treats DNA as a fingerprint, whereas Snapshot treats it as a blueprint -- a genetic description of a person from which physical appearance can be inferred," Greytak said. Parabon's new technology reads the parts of … Continue reading →

Ancient DNA from these animals reveals they are a highly distinct evolutionary lineage. view more Credit: Mike Lee / South Australian Museum Scientists have finally managed to extract DNA from Australia's extinct giant kangaroos - the mysterious marsupial megafauna that roamed Australia over 40,000 years ago. A team of scientists led by Dr Bastien Llamas and Professor Alan Cooper from the University of Adelaide's Australian Centre for Ancient DNA (ACAD) have extracted DNA sequences from two species: a giant short-faced kangaroo (Simosthenurus occidentalis) and a giant wallaby (Protemnodon anak). These specimens died around 45,000 years ago and their remains were discovered in a cold and dry cave in Tasmania. Relatively good preservation conditions in the cave allowed enough short pieces of DNA to survive so researchers could reconstruct partial "mitochondrial genomes" - genetic material transmitted from mother to offspring and widely used to infer evolutionary relationships. "The ancient DNA reveals that extinct giant wallabies are very close relatives of large living kangaroos, such as the red and western grey kangaroos," says lead author Dr Bastien Llamas, ACAD senior research associate. "Their skeletons had suggested they were quite primitive macropods … Continue reading →

DNA molecules provide the "source code" for life in humans, plants, animals and some microbes. But now researchers report an initial study showing that the strands can also act as a glue to hold together 3-D-printed materials that could someday be used to grow tissues and organs in the lab. This first-of-its-kind demonstration of the inexpensive process is described in the brand-new journal ACS Biomaterials Science & Engineering. Andrew Ellington and colleagues explain that although researchers have used nucleic acids such as DNA to assemble objects, most of these are nano-sized -- so tiny that humans can't see them with the naked eye. Making them into larger, visible objects is cost-prohibitive. Current methods also do not allow for much control or flexibility in the types of materials that are created. Overcoming these challenges could potentially have a big payoff -- the ability to make tissues to repair injuries or even to create organs for the thousands of patients in need of organ transplants. With this in mind, Ellington's group set out to create a larger, more affordable material held together with DNA. The researchers developed DNA-coated nanoparticles made of either polystyrene or polyacrylamide. DNA binding adhered these inexpensive nanoparticles to … Continue reading →
