Researchers explain molecular mechanism that induces HER2+ tumours to ignore cell signals

About 30% of breast cancer patients have tumours that show rapid growth and invasion through the body. A common denominator in all of these cases is the presence of a large number of Her2 proteins in tumour cellular membranes. Consequently, these aggressive tumours are referred to as HER2+. Scientists working in the Metastasis Laboratory (MetLab) at IRB Barcelona headed by ICREA researcher Roger Gomis, have described the molecular mechanism that induces HER2+ tumours to ignore the signals that protect cells from excessive growth.

Research finds ways to tackle drug resistance in melanoma

The past year has brought to light both the promise and the frustration of developing new drugs to treat melanoma, the most deadly form of skin cancer. Early clinical tests of a candidate drug aimed at a crucial cancer-causing gene revealed impressive results in patients whose cancers resisted all currently available treatments.

Diogenes study investigates optimum diet composition for preventing, treating obesity

Researchers at the Faculty of Life Sciences (LIFE), University of Copenhagen, can now unveil the results of the world's largest diet study: If you want to lose weight, you should maintain a diet that is high in proteins with more lean meat, low-fat dairy products and beans and fewer finely refined starch calories such as white bread and white rice.

Response to PLX4032 drug short lived in BRAF-mutated metastatic melanoma patients

Researchers with UCLA's Jonsson Comprehensive Cancer Center have found that melanoma patients whose cancers are caused by mutation of the BRAF gene become resistant to a promising targeted treatment through another genetic mutation or the overexpression of a cell surface protein, both driving survival of the cancer and accounting for relapse.

New NIVI tissue-imaging technique can accurately detect cancer cells

The long, anxious wait for biopsy results could soon be over, thanks to a tissue-imaging technique developed at the University of Illinois.

Researchers discover cells’ response to sour tastes

This Thanksgiving, when you bite into the cranberry sauce and the tartness smacks your tongue as hard as that snide comment from your sister, consider the power of sour. Neurobiology researchers at the University of Southern California have made a surprising discovery about how some cells respond to sour tastes.

Chronic high fat cholesterol diet may lead to Alzheimer's disease

Research from the Laboratory of Psychiatry and Experimental Alzheimers Research at the Medical University Innsbruck (Austria) demonstrated that chronic high fat cholesterol diet in rats exhibited pathologies similar to Alzheimer's disease. The results were published in Molecular Cellular Neuroscience with lead author Dr. Christian Humpel. The study was co-authored by PhD students, Celine Ullrich and Michael Pirchl, from the same Laboratory.

Diabetes drug may counteract against Alzheimer's disease: Research

Metformin, a drug used in type 2-diabetes might have the potential to also act against Alzheimer's disease. This has been shown in a study from scientists of the German Center for Neurodegenerative Diseases (DZNE), the University of Dundee and the Max-Planck-Institute for Molecular Genetics.

Best diet: High protein and low good carbs

A group of European researchers have found that eating more protein and fewer refined carbohydrates helps to stay within normal weight. The team showed that men and women who had lost at least eight percent of their body weight on a low-calorie diet were kept on a maintenance diet high in protein and low in refined carbohydrates for six months. They were least likely to regain any weight, and were also the least likely to drop out of the study.

Bacterial study confirms TLR2 signaling vital for activating human airway epithelial cells

Researchers from the Boston University School of Medicine (BUSM) have demonstrated that commensal species of the genus Neisseriae are low inducers of human airway epithelial cell responses as compared to the pathogenic species.

DFG announces establishment of eleven new Collaborative Research Centres

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) will establish eleven new Collaborative Research Centres (CRC) as of 1 January 2011. This decision was made recently by the responsible Grants Committee at its autumn meeting in Bonn. The new CRCs will receive a total of - 94.4 million (including a 20 percent programme allowance for indirect project costs) for an initial funding period of four years.

Amorfix introduces high affinity antibodies against cancer primary cells

Amorfix Life Sciences, a product development company focused on diagnostics and therapeutics for misfolded protein diseases, today announced that together with its partner Epitomics, high affinity antibodies to prion protein disease specific epitopes (DSEs) have been produced, which bind preferentially to several cancer primary cells and tumor cell lines, but not normal cells.

Disrupting estrogen pathway can halt expansion of breast cancer stem cells: Research

Breast cancer stem cells (CSCs), the aggressive cells thought to be resistant to current anti-cancer therapies and which promote metastasis, are stimulated by estrogen via a pathway that mirrors normal stem cell development.

FDA clears BG Medicine's Galectin-3 test to identify high risk patients with cardiovascular disease

BG Medicine, Inc., a U.S.-based life sciences company, announced today that the U.S. Food and Drug Administration has cleared the company's Galectin-3 test for use in conjunction with clinical evaluation as an aid to assess the prognosis of patients diagnosed with chronic heart failure. This marks the first time the FDA has cleared a test to measure galectin-3 blood levels, and is the first novel cardiac test cleared by the FDA in five years.

Parkinson Society Canada awards Quebec scientists $573,384 for research

Quebec Parkinson researchers receive a record $573,384 in funding from Parkinson Society Canada to increase their efforts to identify the causes of this degenerative brain disease for which there is currently no cure. At a Research Innovation event in Montreal this evening, hosted by Parkinson Society Quebec in partnership with McGill University and the CHUM, 11 Parkinson scientists will be lauded for their efforts in getting closer to a cure.

GFAP levels predict brain injury, death in critically ill children on ECMO

Johns Hopkins Children's Center scientists have discovered that high blood levels of a protein commonly found in the central nervous system can predict brain injury and death in critically ill children on a form of life support called extra-corporeal membrane oxygenation or ECMO.
