Harnessing the ID in glioma

2012-12-17
(Press-News.org) Gliomas are the most common form of brain tumor. They are highly aggressive and effective treatments are not currently available. The tumors contain glioma initiating cells (GICs), a population that is highly similar to neural stem cells. GICs drive tumor progression and must stay in a particular extracellular niche in order to maintain their cancer-promoting, stem cell-like characteristics.

In this issue of the Journal of Clinical Investigation, researchers led by Antonio Iavarone at Columbia University report on the role of ID proteins in glioma. ID proteins allow stem cells to stay anchored in a particular extracellular niche.

Using a mouse model of glioma, Iavarone and colleagues found that ID proteins were also responsible for retaining GICs in the extracellular niche that allowed them to maintain their cancer promoting properties. In human glioma patients, the expression of a group of Id-regulated genes was correlated with clinical outcomes.

These results suggest that ID proteins are important regulators of glioma and may be suitable therapeutic targets.

Physicians should not prescribe ADD drugs to healthy people

2012-12-17
Physicians in Canada should consider refusing to prescribe cognitive enhancement medications — also used to treat attention deficit disorder (ADD) — to healthy patients, states an analysis article in CMAJ (Canadian Medical Association Journal). Lack of evidence for benefits and possibility of harm, limited health care resources and professional integrity of physicians are reasons why this use is not acceptable. Prescription stimulants such as methylphenidate and dextroamphetamine are often used by people for "cognitive enhancement" to increase focus, concentration and ...

Rationing soft drink sizes: A good public health move

2012-12-17
New York City's limit of a maximum 16-ounce size of sugar-sweetened drinks for sale in eating establishments is a positive public health move and should be replicated in Canada, argues an editorial in CMAJ (Canadian Medical Association Journal). "Because sugary drinks are the leading source of dietary calories in North America, New York City's latest measure is a rational strategy to combat obesity on a population level," writes Dr. Matthew Stanbrook, Deputy Editor, Practice, CMAJ. "The scientific case for reducing sugar consumption is stronger than ever. Recent evidence ...

New technology allows scientists to capture and preserve cancer cells circulating in the bloodstream

New technology allows scientists to capture and preserve cancer cells circulating in the bloodstream
2012-12-17
Scientists from the RIKEN Advanced Science Institute in Japan and University of California Los Angeles report a new nanoscale Velcro-like device that captures and releases tumor cells that have broken away from primary tumors and are circulating in the bloodstream.This new nanotechnology could be used for cancer diagnosis and give insight into the mechanisms of how cancer spreads throughout the body. The device provides a convenient and non-invasive alternative to biopsy, the current method for diagnosis of metastatic cancer. It could enable doctors to detect tumor cells ...

Surviving sepsis with LECT2

2012-12-17
Failure to launch an adequate immune response may be at the root of septic shock, according to a study published in The Journal of Experimental Medicine on December 17th. Bacterial sepsis is a potentially deadly blood infection that results in massive immune activation and inflammation. Sepsis therapies have traditionally focused on quelling this exaggerated inflammatory response. But a recent study challenged this approach by showing that patients with sepsis had abnormally low levels of an inflammatory protein called LECT2. The new study by Jiong Chen and colleagues ...

Study uncovers mechanism used by BRCA1 to suppress tumors

2012-12-17
WASHINGTON -- A new study by Georgetown University Medical Center researchers reveals how a well-known tumor suppressor gene may be functioning to stop cancer cell growth. The findings, published online today in Oncogene, focus on the gene BRCA1, which is mutated in a majority of families who have hereditary breast and/or ovarian cancers, according to senior author Ronit I. Yarden, PhD, assistant professor in the Department of Human Science at the School of Nursing & Health Studies. "There is a debate in the scientific community about whether BRCA1 enzymatic activity ...

Cats are able to navigate complex combinations of wet and dry foods to achieve a consistent intake of protein, fat and carbohydrate

2012-12-17
Even when provided with complex combinations of different wet and dry foods, cats are able to select and combine the foods in different amounts to achieve a consistent intake of protein, fat and carbohydrate, i.e. macronutrient intake. Published this month in the Journal of Comparative Physiology B, the research shows that cats regulate their macronutrient intake by altering their food selection despite differences in the macronutrient content, moisture level and texture of foods. The research was conducted by scientists from the WALTHAM® Centre for Pet Nutrition – the ...

Brain imaging identifies bipolar disorder risk in adolescents

2012-12-17
Researchers from the University of New South Wales and Black Dog Institute in Sydney, Australia have used brain imaging technology to show that young people with a known risk of bipolar (but as yet have no signs of the condition) have clear and quantifiable differences in brain activity when compared to controls. "We found that the young people who had a parent or sibling with bipolar disorder had reduced brain responses to emotive faces, particularly a fearful face. This is an extremely promising breakthrough," says study leader UNSW Professor Philip Mitchell. "We ...

What's in a genome?

2012-12-17
The species in question is the fruit fly Drosophila mauritiana, a close relative of the well known (and previously sequenced) Drosophila melanogaster that swarms around our fruit bowls in summer. Nolte and colleagues now present a complete genomic sequence, annotating it to indicate the various genes it contains. The information will naturally be extremely useful to all those who are working on this organism. But the present study goes much, much further. Schlötterer's group has recently developed powerful analytic methods for measuring the genetic variability of populations. ...

Preventive detention for oxidizing agents

2012-12-17
Oxidative stress is believed to cause a number of diseases. Up to now, it has been common practice to measure oxidative stress levels by determining the oxidation state of a small molecule called glutathione in cell extracts. Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have been the first to discover that cells under stress deposit their oxidized glutathione in a cellular waste repository. This protects cells from oxidative stress – and questions the validity of the conventional measuring method. Cancer, Alzheimer's, arteriosclerosis– ...
