Fox Chase Cancer Center scientists identify immune-system mutation

...iller cells to the CD4 helper T cell lineage. This indicates that Th-POK is a master regulator of the maturation process." Understanding the development of critical components of the immune system can contribute to medical advances in stimulating desirable immune responses and halting undesirable immune react...

Study Demonstrates Gene Expression Microarrays are Comparable and Reproducible

...eswere the largest source of variation.“This study indicates that microarrays have a high degree ofreproducibility, as long as standardized protocols are carefullyfollowed,?said Jacobson. These promising results will allow this sameresearch group to proceed with a larger gene expression analysis of 600stage I ...

Ancient olfaction protein is shared by many bugs, offering new pest control target

In the battle against insect pests, new research indicates that it may all come down to the sense of smell. A group of Rockefeller University scientists who had previously identified a key gene essential for the sense of smell in fruit flies now shows that this gene's function appears to be evolutionarily co...

Research on Worms Yields Clues on Aging

...extended the lives of worms with no mutations.That indicates the anticonvulsants may affect aging partly throughtheir influence on the neural system involved in the insulin signalingpathway and partly through an independent mechanism, according toKornfeld."Our experiments show there is an important connection ...

New imaging method gives early indication if brain cancer therapy is effective, U-M study shows

...ge relates to the effectiveness of treatment. This indicates a different mixture of cell death pathways within the tumors. In the end, any change is good. When you think about it, if the treatment is not having an effect, the tumor will continue to grow without any change to water diffusion," Ross said. The r...

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

... to measure oxygen," Bradley said. "Their behavior indicates they are regulating oxygen." Bradley and Hetz will next work on developing a comprehensive model of insect breathing. "We'd like to expand our present model to explain all aspects of insect breathing. And we'd like to examine insects that do not sho...

NC State scientist finds soft tissue in T. rex bones

...recognizable organic features. Since current data indicates that living birds are more closely related to dinosaurs than any other group, Schweitzer compared the findings from the T. rex with structures found in modern-day ostriches. In both samples, transparent branching blood vessels were present, and many ...

Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed

... Dome from 1997-99, along with other calculations, indicates ice in that area has lost only 200 to 400 meters of its thickness in the last 20,000 years, said Edwin Waddington, a UW professor of Earth and space sciences. Like water on a hillside, Siple Dome ice flows down into adjacent ice streams, where it co...

UCSD discovery may help extend life of natural pesticide

...spread." According to the researchers, prior work indicates that there are other receptors that also contribute to Bt resistance. Combining pesticides that work through different receptors or designing pesticides that can work through more than one receptor type could thwart the development of resistance. "T...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

...are often similar across species. "This new result indicates that the way in which the most functionally important proteins are assembled into machinery from one species to another is also, to a certain degree, conserved," said Ideker. "The circuitry is not exactly the same. In fact, there are striking differe...

Researchers devise way to mass-produce embryonic stem cells

...r two key proteins. The presence of these proteins indicates that a stem cell has not differentiated. In the bioreactor experiment, 94 percent of the stem cells tested positive for these proteins, compared to about 85 percent of the cells grown in the flask. The researchers are now working on ways to program ...

Increased risk of osteoporosis associated with gene that one in five people have

...than normal urinary concentration of a marker that indicates bone resorption and had significantly lower than normal bone density in regions of the upper femur near the hip joint. "The data suggest that this particular variation of the gene produces an enzyme that breaks down estrogen faster than usual, leadi...

Scientists identify molecule that regulates well-known tumor suppressor

...by activity of the tumor suppressor PTEN. Research indicates that PTEN exerts its tumor suppressor activity by inhibiting PKB/Akt signaling that is critical for cell survival. Many human cancer cells exhibit mutations in the PTEN gene, but other cancers have the normal PTEN gene. While it is clear that without...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

... that becomes attracted to these traits. Our study indicates what happens in the brain of the viewer as he or she becomes physiologically attracted to these traits." She added, "This brain system probably evolved for an important reason ?to drive our forebears to focus their courtship energy on specific indiv...

Reservoirs may accelerate the spread of invasive aquatic species, researchers say

... and the copepod Eurytemora affinis. Some evidence indicates that the spread of zebra mussels, an economically important invasive species, may also have made use of reservoirs to spread. Havel, Lee, and Vander Zanden argue for research aimed at comparing rates of invasion in freshwater lakes and reservoirs tha...

Silence the gene, save the cell: RNA interference as promising therapy for ALS

...uron cells," Aebischer notes. Recent research also indicates that mutant SOD1 gene expression in neighboring glial cells is also implicated in motor neuron death. Lead author Cedric Raoul and colleagues targeted the cause of the disease by using RNA interference to silence the defective gene, preventing it fr...

Live vaccines more effective against horse herpes virus

...niversity virologist says his preliminary research indicates that vaccines containing weakened live viruses, called modified live vaccines (MLV), appear to be more effective in preventing horse herpes than other more widely used vaccines. "It's important that people know that the MLV has been in use for decad...

Gladstone investigators discover how resting T cells avoid HIV infection

...roduce its antiviral effects. The new Nature study indicates that this is not the case in resting T-cells. The Greene lab showed that in activated T cells, however, Vif, one of HIV's nine genes, counters the antiviral effect of A3G by binding to it and accelerating its destruction as well as decreasing is prod...

New polysaccharide may help combat multidrug resistance in cancer

...increased resistance to drug treatment. "Our work indicates that hyaluronan antagonists, for example small hyaluronan oligomers, reverse the malignant properties of cancer cells, including proliferation, invasiveness, and drug resistance," explains Dr. Toole. "Hyaluronan oligomers are non-toxic, non-immunogen...
