Exposure to arsenic can turn normal stem cells into cancer stem cells

Researchers at the National Institutes of Health have discovered how exposure to arsenic can turn normal stem cells into cancer stem cells and spur tumor growth. Inorganic arsenic, which affects the drinking water of millions of people worldwide, has been previously shown to be a human carcinogen.

Emotional response of persons linked to series of television adverts

What effect does a TV advert have on a viewer? How does it bring about a change in their knowledge, emotions or intentions? These questions have existed alongside advertising ever since it began. Through a psycho-physiological study developed jointly by El Bureau de la Comunicaci-n, the Tecnalia Centre for Applied Research, and the UPV/EHU, it has been possible to measure the emotional response of a person to a series of television adverts.

Study: Functional link between two major causes of treatment failure in breast cancer

Research from The Cancer Institute of New Jersey (CINJ) shows a functional link between two major causes of treatment failure in breast cancer, showing the protein behind one of these causes plays a role in increasing the drug resistance properties of the other.

Researchers identify how neural cells build up resistance to opioid pain drugs within hours

Researchers at the University of Montreal's Sainte-Justine Hospital have identified how neural cells are able to build up resistance to opioid pain drugs within hours. "A better understanding of these mechanisms will enable us to design drugs that avoid body resistance to these drugs and produce longer therapeutic responses, including prolonged opioid analgesia", lead author Dr. Graciela Pineyro said.

Novel method creates 3-D clusters of pancreatic beta-cells

Three-dimensional clusters of pancreatic beta-cells that live much longer and secrete more insulin than single cells grown in the laboratory are valuable new tools for studying pancreatic diseases such as diabetes and for testing novel therapies.

TLR4/MD-2 protein complex triggers morphine-induced inflammation

A University of Colorado Boulder-led research team has discovered that two protein receptors in the central nervous system team up to respond to morphine and cause unwanted neuroinflammation, a finding with implications for improving the efficacy of the widely used painkiller while decreasing its abuse potential.

Combination treatment effective against melanoma

Research from The Cancer Institute of New Jersey (CINJ) shows that a coordinated effort to block signaling pathways that promote cancer cell growth and survival enhances programmed cell death in melanoma.

Cell graphs link structure of human tissue to corresponding biological function

Computer scientists and biologists in the Data Science Research Center at Rensselaer Polytechnic Institute have developed a rare collaboration between the two very different fields to pick apart a fundamental roadblock to progress in modern medicine. Their unique partnership has uncovered a new computational model called "cell graphs" that links the structure of human tissue to its corresponding biological function.

Scientists discover new serine protease: NSP4

Neutrophil granulocytes comprise important defences for the immune system. When pathogenic bacteria penetrate the body, they are the first on the scene to mobilise other immune cells via signal molecules, thereby containing the risk. To this end, they release serine proteases - enzymes that cut up other proteins to activate signal molecules. Scientists at the Max Planck Institute of Neurobiology in Martinsried have now discovered a new serine protease: neutrophil serine protease 4, or NSP4.

MEK1 mutation does not necessarily make BRAF mutant melanomas resistant to inhibitors

A second mutation found in the tumors of patients with BRAF-mutated metastatic melanoma does not contribute to resistance to BRAF inhibitor drugs, a finding that runs counter to what scientists expected to be true.

Metformin may slow growth rate of prostate cancer in men

The use of metformin in men with prostate cancer before prostatectomy helped to reduce certain metabolic parameters and slow the growth rate of the cancer, according to the results of a phase II study.

Brain images show nerves ‘crisscrossing’ in neat but complex patterns: Study

New images of the brain reveal a deceptively simple pattern of organization in the wiring of this complex organ. Instead of nerve fibers travelling randomly through the brain like spaghetti, as some imaging has suggested, the new portraits reveal two-dimensional sheets of parallel fibers ‘crisscrossing’ other sheets at right angles in a grid-like structure that folds and contorts with the convolutions of the brain. This same pattern appeared in the brains of humans, rhesus monkeys, owl monkeys, marmosets and galagos, researchers report Thursday in the journal Science.

Thermally content mice might serve as meaningful research subjects

Nine out of 10 drugs successfully tested in mice and other animal models ultimately fail to work in people, and one reason may be traced back to a common fact of life for laboratory mice: they're cold, according to a researcher at the Stanford University School of Medicine.
