St. Jude study solves mystery of mammalian ears

...rtment of Developmental Neurobiology. “There are a variety of causes for hearing loss, including side effects of chemotherapy for cancer. One strength of St. Jude is that researchers have the ability to ask some very basic questions about how the body works, and then use those answers to solve medical proble...

Scratch no more: Gene for itch sensation discovered

...Normal mice scratched vigorously when exposed to a variety of itch-producing substances, but the knockout mice scratched much less. "The fact that the knockout mice still scratched a little suggests there are additional itch receptors," Chen says. "We know of some proteins that are similar to GRPR, so now we...

Cells re-energize to come back from the brink of death

... 1 issue of “Cell.” Apoptosis is triggered by a variety of factors, including gene mutations that can make the cell become cancerous. During apoptosis, the membrane covering the cell’s mitochondria develop holes and leak a molecule called cytochrome c, which triggers the activity of enzymes called caspase...

CSIRO scientists join fight to save 'Tassie devil'

... The integrated research team at AAHL will use a variety of techniques including microscopy, microarrays and a range of molecular techniques to search for infectious agents, markers for disease and to determine where the tumours originate. “We will be working in a number of areas including establishi...

Study shows big power of small RNAs, not just proteins, in halting cancer

...on. By comparing levels of miRNAs in cells with a variety of pre-cancerous genetic lesions, CSHL researchers found a connection between changes in the p53 pathway and the loss of a specific family of miRNAs, known as miR-34. The fact that p53 uses miRNAs to stop tumor cell growth reveals a completely new d...

Brightening prospects of using fluorescent nanotubes in medical applications

...e that has restricted fluorescent nanotubes from a variety of medical applications, including anti-cancer treatments. In a paper published online in the Journal of the American Chemical Society on June 7, they describe a method that can successfully produce large batches of highly fluorescent nanotubes. “...

Breakthrough developments in rheumatoid arthritis reported

...e with these antibodies who also have a particular variety of HLA, a complex of genes that regulate immune function, have a 30 times higher risk of developing rheumatoid arthritis than those without these genetic risk factors. Scientists at the University of Colorado are now analyzing the genes from 2,5...

U-M researchers discover gene switched off in cancer can be turned on

...rticular, although they found similar results in a variety of other cancer cell lines tested. A potential target to treat lung cancer is particularly crucial as the death rate from lung cancer has not changed in 30 years. Newer treatments are much less toxic and extend lives by months, but the same people wh...

Newly discovered antibody may be body's natural defense against Alzheimer's

... forms of other proteins that accumulate in a wide variety of diseases, such as Parkinson's, Lewy body dementia and Prion disease (the human form of ‘Mad Cow' disease), to name a few," says Dr. Relkin. Since beta amyloid oligomers are much less abundant in the body than the single-molecule variety, the r...

Penn researchers link cell's protein recycling systems

... this molecular link can be used to benefit a wide variety of neurodegenerative diseases because accumulation of toxic proteins is a common underlying feature of age-related neurodegeneration.” Taylor and his group study fruit flies in which the proteasome is disabled by a genetic mutation, which results...

Bacteria ferry nanoparticles into cells for early diagnosis, treatment

... can potentially deliver specific molecules into a variety of cells," said Akin, the first author of a research paper appearing online this week in the journal Nature Nanotechnology. Experiments were carried out in cultures of human cancer cells, including intestinal, oral, liver, ovarian and breast cance...

Researchers demonstrate way to control tree height

...ngineering techniques. It opens the door to a wide variety of new products for the ornamental and nursery industries, experts say, if regulatory hurdles can be overcome – a big “if.” The findings were recently published in the journal Landscape Plant News. “From a science perspective, this is a very ...

Human genetic 'deserts' are teeming with significant life

...ll be surprised if we do not find the same kind of variety in these structures”, he says. “Our work has shown that the human genome is far more complex than anyone could have imagined, even ten years ago. Understanding these complexities is essential to the development of effective and safe genetic medic...

CU study reveals why starling females cheat
