rAAV/ABAD-DP-6His attenuates oxidative stress induced injury of PC12 cells

rAAV/ABAD-DP-6His attenuates oxidative stress induced injury of PC12 cells
2014-05-07
(Press-News.org) The effects of Amyloid beta (Aβ)-Aβ-binding alcohol dehydrogenase (ABAD) may exacerbate Alzheimer's disease pathology. Therefore, blocking Aβ-ABAD-mediate effects with ABAD decoy peptide (ABAD-DP) may be a potential therapeutic strategy for Alzheimer's disease. Dr. Jiang Wu and team from the First Hospital of Jilin University in China successfully constructed a recombinant adenovirus constitutively secreting and expressing Aβ-ABAD decoy peptide (rAAV/ABAD-DP-6His). Their results showed that rAAV/ABAD-DP-6His increased superoxide dismutase activity in hydrogen peroxide-induced oxidative stress-mediated injury of PC12 cells. Moreover, rAAV/ABADDP-6His decreased malondialdehyde content, intracellular Ca2+ concentration, and the level of reactive oxygen species. rAAV/ABAD-DP-6His maintained the stability of the mitochondrial membrane potential. In addition, the ATP level remained constant, and apoptosis was reduced. Overall, the experimental findings, published in the Neural Regeneration Research (Vol. 9, No. 5, 2014), indicate that rAAV/ABAD-DP-6His generates the fusion peptide, Aβ-ABAD decoy peptide, which effectively protects PC12 cells from oxidative stress injury induced by hydrogen peroxide, thus exerting neuroprotective effects.

Starting signal for antiviral defense

2014-05-07
In human cells, DNA occurs only in the cell nucleus as the carrier of genetic information. In order to protect it, specialized proteins regularly scan the individual strands for defects, and repair them. One example of this is the protein Rad50, a DNA sensor that binds to DNA and detects defective sites. A team of scientists headed by Prof. Jürgen Ruland of the TUM together with colleagues from the LMU have now discovered another important task performed by Rad50. There is normally no DNA in the cytoplasm surrounding the cell nucleus. However, if any does turn up there, ...

Amyloid-β (Aβ) plaques and neurofibrillary tangles are the main pathological hallmarks of Alzheimer's disease, as well as the loss of neurons and synapses. recent reports have shown that estrogen exerts neuroprotective effects. However, large clinical trials in postmenopausal women indicated adverse side-effects of estrogens, such as increased incidence of breast cancer and metrocarcinoma, thereby preventing clinical use of estrogen. Tongluojiunao (TLJN) is an herbal medicine consisting of two main components, geniposide and ginsenoside Rg1. Prof. Qian Hua and ...

Discovery offers new possibilities for clean energy research

2014-05-07
University of Houston physicists have discovered a new thermoelectric material offering high performance at temperatures ranging from room temperature up to 300 degrees Celsius, or about 573 degrees Fahrenheit. "This new material is better than the traditional material, Bismuth telluride, and can be used for waste heat conversion into electricity much more efficiently," said Zhifeng Ren, M.D. Anderson Chair professor of physics at UH and the lead author of a paper describing the discovery, published online by Nano Energy. Ren, who is also principal investigator at the ...

Ability to isolate and grow breast tissue stem cells could speed cancer research

Ability to isolate and grow breast tissue stem cells could speed cancer research
2014-05-07
LA JOLLA—By carefully controlling the levels of two proteins, researchers at the Salk Institute have discovered how to keep mammary stem cells—those that can form breast tissue—alive and functioning in the lab. The new ability to propagate mammary stem cells is allowing them to study both breast development and the formation of breast cancers. "What we've shown is that we can take these cells out of a mouse and study them and regulate them in the laboratory by providing them with a specific factor," says Peter C. Gray, a staff scientist in Salk's Clayton Foundation ...

Today's offenders are tomorrow's victims in gangs

2014-05-07
HUNTSVILLE, TX (5/7/14) -- Gang members are twice as likely to become both a victim and an offender of a crime than non-gang members, as single acts of violence often lead to retribution between gangs as a whole, according to a new study. "In other words, gang members are not distinctly offenders or victims; instead, gang membership is a common source of both forms of violence," said David Pyrooz, an assistant professor at Sam Houston State University, College of Criminal Justice and principal author of the study. "Today's criminal offender is tomorrow's victim, and today's ...

Arctic study sheds light on tree-ring divergence problem

2014-05-07
SAN FRANCISCO -- Changes in tree-ring density in the Arctic may be evidence of changes in light intensity during the trees' growth, according to a new study by San Francisco State University researcher Alexander Stine. The finding has direct implications for the tree-ring "divergence problem," a phenomenon that has received considerable media attention but has been widely misinterpreted, said Stine, an assistant professor of Earth & climate sciences. Tree rings consist of a low density ring, which forms early in the growing season, and a high density ring that forms ...

Newly found dinosaur is long-nosed cousin of Tyrannosaurus rex

Newly found dinosaur is long-nosed cousin of Tyrannosaurus rex
2014-05-07
Scientists have discovered a new species of long-snouted tyrannosaur, nicknamed Pinocchio rex, which stalked the Earth more than 66 million years ago. Researchers say the animal, which belonged to the same dinosaur family as Tyrannosaurus rex, was a fearsome carnivore that lived in Asia during the late Cretaceous period. The newly found ancient predator looked very different from most other tyrannosaurs. It had an elongated skull and long, narrow teeth compared with the deeper, more powerful jaws and thick teeth of a conventional T. rex. Palaeontologists were uncertain ...

Melting an entire iceberg with a hot poker: Spotting phase changes triggered by impurities
2014-05-07
"What a curious feeling," says Alice in Lewis Carroll's tale, as she shrinks to a fraction of her size, and everything around her suddenly looks totally unfamiliar. Scientists too have to get used to these curious feelings when they examine matter on tiny scales and at low temperatures: all the behaviour we are used to seeing around us is turned on its head. In research published today in the journal Nature Communications, UCL scientists have made a startling discovery about a familiar physical effect in this unfamiliar setting. Phase transitions are a category of ...

Sprites form at plasma irregularities in the lower ionosphere

Sprites form at plasma irregularities in the lower ionosphere
2014-05-07
Atmospheric sprites have been known for nearly a century, but their origins were a mystery. Now, a team of researchers has evidence that sprites form at plasma irregularities and may be useful in remote sensing of the lower ionosphere. "We are trying to understand the origins of this phenomenon," said Victor Pasko, professor of electrical engineering, Penn State. "We would like to know how sprites are initiated and how they develop." Sprites are an optical phenomenon that occur above thunderstorms in the D region of the ionosphere, the area of the atmosphere just above ...

International molecular screening program for metastatic breast cancer AURORA at IMPAKT

2014-05-07
While research has made great strides in recent decades to improve and significantly extend the lives of patients with early breast cancer, the needs of patients with advanced or metastatic disease have largely been ignored. Moreover, despite the fact that the overall breast cancer death rate has dropped steadily over the last decade and significant improvements in survival have been made, metastatic breast cancer represents the leading cause of death among patients with the disease. In this context the Breast International Group (BIG) recently launched AURORA, which ...
