New RNA-based therapeutic strategies for controlling gene expression

New RNA-based therapeutic strategies for controlling gene expression
2012-02-06
(Press-News.org) New Rochelle, NY, February 2, 2012—Small RNA-based nucleic acid drugs represent a promising new class of therapeutic agents for silencing abnormal or overactive disease-causing genes, and researchers have discovered new mechanisms by which RNA drugs can control gene activity. A comprehensive review article in Nucleic Acid Therapeutics, a peer-reviewed journal published by Mary Ann Liebert, Inc., details these advances.

Short strands of nucleic acids, called small RNAs, can be used for targeted gene silencing, making them attractive drug candidates. These small RNAs block gene expression through multiple RNA interference (RNAi) pathways, including two newly discovered pathways in which small RNAs bind to Argonaute proteins or other forms of RNA present in the cell nucleus, such as long non-coding RNAs and pre-mRNA.

Keith T. Gagnon, PhD, and David R. Corey, PhD, University of Texas Southwestern Medical Center, in Dallas, review common features shared by RNAi pathways for controlling gene expression and focus in detail on the potential for Argonaute-RNA complexes in gene regulation and other exciting new options for targeting emerging forms of non-coding RNAs and pre-mRNAs in the article "Argonaute and the Nuclear RNAs: New Pathways for RNA Mediated Control of Gene Expression."

"The field of RNA mediated control of gene expression is rapidly evolving and the article by Gagnon and Corey provides a highly informative and up to date review of this exciting and often surprising area of biomedical research. We are delighted to publish this important review for the field," says Co-Editor-in-Chief Bruce A. Sullenger, PhD, Duke Translational Research Institute, Duke University Medical Center, Durham, NC.

Hubble zooms in on a magnified galaxy

Hubble zooms in on a magnified galaxy
2012-02-06
Thanks to the presence of a natural "zoom lens" in space, NASA's Hubble Space Telescope got a uniquely close-up look at the brightest "magnified" galaxy yet discovered. This observation provides a unique opportunity to study the physical properties of a galaxy vigorously forming stars when the universe was only one-third its present age. A so-called gravitational lens is produced when space is warped by a massive foreground object, whether it is the sun, a black hole or an entire cluster of galaxies. The light from more-distant background objects is distorted, brightened ...

'First light' taken by NASA's newest CERES instrument

First light taken by NASAs newest CERES instrument
2012-02-06
The doors are open on NASA's Suomi NPP satellite and the newest version of the Clouds and the Earth's Radiant Energy System (CERES) instrument is scanning Earth for the first time, helping to assure continued availability of measurements of the energy leaving the Earth-atmosphere system. The CERES results help scientists to determine the Earth's energy balance, providing a long-term record of this crucial environmental parameter that will be consistent with those of its predecessors. CERES arrived in space Oct. 28, 2011, carried by NASA's newest Earth-observing satellite, ...

NASA satellites see wind shear battering Tropical Depression Iggy

NASA satellites see wind shear battering Tropical Depression Iggy
2012-02-06
NASA satellites have watched as wind shear has torn Cyclone Iggy apart over the last day. NASA infrared satellite imagery showed that Iggy's strongest thunderstorms have been pushed away from the storm's center and visible imagery shows the storm is being stretched out. Iggy is weakening and heading for a landfall between Geraldton and Perth. When NASA's Aqua satellite passed over Tropical Cyclone Iggy on Feb. 1 at 1805 UTC (1:05 p.m. EST), the Atmospheric Infrared Sounder (AIRS) instrument aboard captured an infrared look at the cyclone. AIRS data showed that the strongest ...

A battle of the vampires, 20 million years ago?

2012-02-06
CORVALLIS, Ore. – They are tiny, ugly, disease-carrying little blood-suckers that most people have never seen or heard of, but a new discovery in a one-of-a-kind fossil shows that "bat flies" have been doing their noxious business with bats for at least 20 million years. For bats, that's a long time to deal with a parasite doing its best vampire impression. Maybe it is nature's revenge on the vampire bat, an aggressive blood consumer in its own right that will feed on anything from sheep to dogs and humans. The find was made by researchers from Oregon State University ...

Breastfeeding and lung function at school age: Does maternal asthma modify the effect?

2012-02-06
Breastfeeding is associated with improved lung function at school age, particularly in children of asthmatic mothers, according to a new study from researchers in Switzerland and the UK. "In our cohort of school age children, breastfeeding was associated with modest improvement in forced mid-expiratory flow (FEF50) in our whole group and with improvements in forced vital capacity (FVC) and forced expiratory volume at 1 second (FEV1) only in the children of asthmatic mothers," said Claudia E. Kuehni, MD, MSc, professor at the Institute of Social and Preventive Medicine ...

Classic portrait of a barred spiral galaxy

Classic portrait of a barred spiral galaxy
2012-02-06
Most spiral galaxies in the Universe have a bar structure in their centre, and Hubble's image of NGC 1073 offers a particularly clear view of one of these. Galaxies' star-filled bars are thought to emerge as gravitational density waves funnel gas toward the galactic centre, supplying the material to create new stars. The transport of gas can also feed the supermassive black holes that lurk in the centres of almost every galaxy. Some astronomers have suggested that the formation of a central bar-like structure might signal a spiral galaxy's passage from intense star-formation ...

New procedure repairs severed nerves in minutes, restoring limb use in days or weeks

2012-02-06
American scientists believe a new procedure to repair severed nerves could result in patients recovering in days or weeks, rather than months or years. The team used a cellular mechanism similar to that used by many invertebrates to repair damage to nerve axons. Their results are published today in the Journal of Neuroscience Research. "We have developed a procedure which can repair severed nerves within minutes so that the behavior they control can be partially restored within days and often largely restored within two to four weeks," said Professor George Bittner from ...

New technique dissolves blood clots in the brain and lowers risk of brain damage after stroke

2012-02-06
Johns Hopkins neurologists report success with a new means of getting rid of potentially lethal blood clots in the brain safely without cutting through easily damaged brain tissue or removing large pieces of skull. The minimally invasive treatment, they report, increased the number of patients with intracerebral hemorrhage (ICH) who could function independently by 10 to 15 percent six months following the procedure. At the International Stroke Conference taking place January 31 through February 2 in New Orleans, the researchers will present their findings from 93 patients, ...

New technology to tackle treatment-resistant cancers

2012-02-06
Free-flowing cancer cells have been mapped with unprecedented accuracy in the bloodstream of patients with prostate, breast and pancreatic cancer, using a brand new approach, in an attempt to assess and control the disease as it spreads in real time through the body, and solve the problem of predicting response and resistance to therapies. In comparison to a previous generation of systems, the researchers state their test showed a significantly greater number of high-definition circulating tumour cells (HD-CTCs), in a higher proportion of patients, by using a computing-intensive ...

NYU Courant researchers weigh methods to more accurately measure genome sequencing

2012-02-06
Lost in the euphoria of the 2003 announcement that the human genome had been sequenced was a fundamental question: how can we be sure that an individual's genome has been read correctly? While the first full, individual genome was sequenced a decade ago, given the vast genetic variation across the world's seven billion people, not to mention the differences in makeup even among close relatives, the question of accurate sequencing for individuals has continued to vex researchers. With companies now projecting they can sequence a genome for a $1,000, down from $25,000 ...
