Fly study finds two new drivers of RNA editing

RNA editing gives organisms a way to adapt the instructions that their DNA provides for making proteins. Few people would have described RNA editing as a simple process, but a new paper in Nature Communications demonstrates the process as more complex and difficult to predict than previously assumed. The study, done in living fruit flies, discovered two new mechanisms that govern editing in a key neurodevelopmental gene. …read more

RNA-interference pesticides will need special safety testing

Standard toxicity testing is inadequate to assess the safety of a new technology with potential for creating pesticides and genetically modifying crops, according to a Forum article published in the August issue of BioScience. The authors of the article, Jonathan G. Lundgren and Jian J. Duan of the USDA Agricultural Research Service, argue that pesticides and insect-resistant crops based on RNA interference, now in exploratory development, may have to be tested under elaborate procedures that assess effects on animals’ whole life cycles, rather than by methods that look for short-term toxicity. …read more

Study visualizes mRNA transport in test tube

(Phys.org) —Much of biomedical science – both mystifying and awe-inspiring to the lay public – depends on an unwavering focus on things that can’t be easily seen, like the inner-workings of cells, in order to determine how and why disease develops. New research authored by Thomas Sladewski, a University of Vermont graduate student working in the laboratory of Kathleen Trybus, Ph.D., and colleagues, provides a rare “picture” of the activity taking place at the single molecular level: visual evidence of the mechanisms involved when a cell transports mRNA (or messenger RNA) to where a protein is needed to perform a cellular function. …read more

Illumina Announces Favorable Outcome of Its Patent Litigation Against Life Technologies, Inc.

SAN DIEGO–(BUSINESS WIRE)– Illumina, Inc. (NAS: ILMN) announced today that District Court Judge Cathy Ann Bencivengo of the U.S. District Court for the Southern District of California granted Illumina’s motion for summary judgment that its sequencing systems do not infringe U.S. Patent Nos. 5,616,478; 5,958,698 and 6,001,568, being asserted by Life Technologies Corporation in a lawsuit filed against Illumina in 2009. The Court ruled that, “Life Tech cannot establish, as a matter of law, that the accused Illumina systems infringe” the patents.

Jay Flatley, Illumina’s President and CEO, stated, “We are obviously very pleased with the favorable outcome of this suit. Since Life Technologies filed this patent infringement suit against Illumina in 2009, we have consistently believed and strongly argued that our sequencing technology does not infringe any of the patents Life Technologies asserted against us in this case. The federal court’s ruling has now vindicated our position. While our policy is to respect the valid and enforceable intellectual property rights of others, and take licenses where appropriate, this case demonstrates we are determined to defend vigorously any unfounded claims of infringement.”

Illumina Announces Outcome of Its Patent Litigation Against Syntrix Biosystems, Inc.

SAN DIEGO–(BUSINESS WIRE)– Illumina, Inc. (NAS: ILMN) today announced that a federal jury in Tacoma, Washington found that Illumina’s BeadChip array product infringed U.S. Patent No. 6,951, 682, asserted by Syntrix Biosystems, Inc. The federal jury ordered Illumina to pay approximately $96 million in damages to Syntrix based on a royalty rate of six percent for BeadChip products sold by Illumina from 2005 through May 2012. United States District Court Judge Benjamin H. Settle, however, dismissed from the case claims that Illumina’s alleged infringement was willful and that Illumina misappropriated Syntrix’s trade secrets. The Syntrix patent expires on September 17, 2019.

Illumina continues to believe that Syntrix’s claims are without merit. Illumina intends to file post-trial motions asking the court to vacate the jury’s finding and to rule as a matter of law that the BeadChip does not infringe Syntrix’s patent.

Jay Flatley, Illumina’s President and CEO, stated, “We strongly disagree with this verdict and plan to appeal the present finding of infringement. In the meantime, we will continue to sell the products that are the subject of this suit and no damages will be payable to Syntrix until all appropriate appeals have been taken, which may take a number of years.” Mr. Flatley continued, “Our BeadChip products are based on Dr. David Walt‘s technology that was licensed from Tufts University when Illumina was founded in 1998. Like many other companies, we respect the valid and enforceable intellectual property rights of others. Consistent with our policy, we believe we acted properly with respect to the Syntrix ‘682 patent. We continue to feel very strongly about our position that Syntrix’s allegations are without merit and that, ultimately, our position will be vindicated.”

Arrowhead Receives Notice of Patent Allowance for New Protease Sensitive Masking Chemistry for DPC siRNA Delivery System

PASADENA, Calif.–(BUSINESS WIRE)– Arrowhead Research Corporation (NAS: ARWR) , a targeted therapeutics company, today announced that it has received a Notice of Allowance from the U.S. Patent and Trademark Office for U.S. Patent Application Number 13/336,028 entitled, “In Vivo Polynucleotide Delivery Conjugates Having Enzyme Sensitive Linkages.” This new IP expands the Dynamic Polyconjugate (DPC) platform, broadly protecting Arrowhead’s next generation DPC polymer masking technology. Using this masking technology, DPCs can be engineered for long circulation times and improved tissue-targeting characteristics. In addition, hepatocyte-targeted DPCs formulated using this new masking technology have shown to be highly potent upon subcutaneous administration. The company has previously reported target gene knockdown of 99% in monkeys after a single subcutaneous injection of 1 mg/kg, with >80% knockdown for 3 months. Additional data will be reported at upcoming scientific conferences and through peer-reviewed publications.

“This patent protects a new masking chemistry that broadens the reach of DPC-enabled RNAi therapeutics. It enables efficient subcutaneous delivery of siRNA and opens up new therapeutic area targets including oncology,” said Dr. Chris Anzalone, President and CEO of Arrowhead. “Arrowhead scientists continue to discover innovative solutions for siRNA delivery and we look forward to providing updates on how these technologies are being deployed to create new drug candidates.”

Molecules assemble in water, hint at origins of life

(Phys.org)—The base pairs that hold together two pieces of RNA, the older cousin of DNA, are some of the most important molecular interactions in living cells. Many scientists believe that these base pairs were part of life from the very beginning and that RNA was one of the first polymers of life. But there is a problem. The RNA bases don’t form base pairs in water unless they are connected to a polymer backbone, a trait that has baffled origin-of-life scientists for decades. If the bases don’t pair before they are part of polymers, how would the bases have been selected out from the many molecules in the “prebiotic soup” so that RNA polymers could be formed? …read more

Paired genes in stem cells shed new light on gene organization and regulation

Whitehead Institute researchers have determined that DNA transcription, the process that produces messenger RNA (mRNA) templates used in protein production, also runs in the opposite direction along the DNA to create corresponding long noncoding RNAs (lncRNAs). Moreover, the mRNAs and lncRNAs are transcribed coordinately as stem cells differentiate into other cell types. This surprising finding could redefine our understanding of gene organization and its regulation.
