Molecular flexibility shown to help pharmaceutical drugs bind to their targets
Scientists have discovered an alternative way to create a stronger binding between pharmaceutical drugs and the part of the body they are targeting -- a development that can be used to fight a variety of diseases, including breast cancer. The study published in PLOS Computational Biology shows that flexible molecules, instead of rigid ones, as previously thought, can bind more effectively to the proteins causing the disease.

Insights on lung micro-environment explain why cancer spreads to the lungs
The same mechanisms that that prevent people from having an inflammatory response to harmless environmental exposures in day-to-day life could also all allow rogue cancer cells to spread to the lungs, according to new research from The Ohio State University Comprehensive Cancer Center. Researchers have discovered and described how the lung's unique underlying immune environment enables cancer to readily spread to the organ.

Excess weight linked to 8 more cancer types
There's yet another reason to maintain a healthy weight as we age. An international team of researchers has identified eight additional types of cancer linked to excess weight and obesity: stomach, liver, gall bladder, pancreas, ovary, meningioma (a type of brain tumor), thyroid cancer and the blood cancer multiple myeloma.

UCF technology for killing metastatic breast cancer cells discovered, licensed
A University of Central Florida cancer researcher has discovered a way to kill spreading breast cancer cells and her new technology has generated a licensing agreement that will accelerate the therapy's path to clinical trials. Metastatic cancer cells that spread from the original tumor to the brain, lungs and bones are the leading cause of death for most cancer patients, said Annette Khaled, the researcher who made the discovery. Her work is featured in the September edition of Clinical Cancer Research.

50 years after the release of the film 'Fantastic Voyage,' science upstages fiction
Fifty years to the day after the film 'Fantastic Voyage' was first shown in theaters, the Polytechnique Montréal Nanorobotics Laboratory is unveiling a unique medical interventional infrastructure devoted to the fight against cancer. The outcome of 15 years of research conducted by Professor Sylvain Martel and his team, it enables microscopic nanorobotic agents to be guided through the vascular systems of living bodies, delivering drugs to targeted areas.

Fateful evolution: New study improves accuracy of cancer diagnosis
In a new study, Carlo Maley, a researcher at Arizona State University's Biodesign Institute, uses evolutionary theory to make predictions about which BE patients will go on to develop cancer. The results, which appear in the current issue of the journal Nature Communications, point the way toward more accurate medical assessments for patients with BE and the development of early-warning beacons of disease known as biomarkers.

Smokers with newly discovered genetic markers have higher lung cancer risk
University of Hawai'i Cancer Center researchers discovered new genetic markers associated with a fast rate of nicotine metabolism, which potentially leads smokers to smoke more, thereby, increasing their risk for lung cancer.

Johns Hopkins scientists track metabolic pathways to find drug combination for pancreatic cancer
Cancer researchers have long observed the value of treating patients with combinations of anti-cancer drugs that work better than single drug treatments. Now, in a new study using laboratory-grown cells and mice, Johns Hopkins scientists report that a method they used to track metabolic pathways heavily favored by cancer cells provides scientific evidence for combining anti-cancer drugs, including one in a nanoparticle format developed at Johns Hopkins, that specifically target those pathways.

Nanofiber scaffolds demonstrate new features in the behavior of stem and cancer cells
A discovery in the field of biomaterials may open new frontiers in stem and cancer cell manipulation and associated advanced therapy development. Novel scaffolds are shown enabling cells to behave in a different but controlled way in vitro due to the presence of aligned, self-assembled ceramic nanofibers of an ultra-high anisotropy ratio augmented into graphene shells.

New study provides important insight into how tumors metastasize
Research has shown that the growth of cancerous tumors is affected by Transforming growth factor (TGFbeta) in the body's cells; TGFbeta both suppresses and stimulates tumor development, but it has not been understood how this happens. A new study published in the journal Science Signaling today reveals important details behind this process.

Analog DNA circuit does math in a test tube
Duke University researchers have created strands of synthetic DNA that, when mixed together in a test tube in the right concentrations, form an analog circuit that can add, subtract and multiply as the molecules form and break bonds. While most DNA circuits are digital, their device performs calculations in an analog fashion by measuring the varying concentrations of specific DNA molecules directly, without requiring special circuitry to convert them to zeroes and ones first.

Melatonin boost a key to fighting breast cancer
Melatonin, a hormone produced in the human brain, appears to suppress the growth of breast cancer tumors. Researchers at Michigan State University published this finding in the current issue of Genes and Cancer. While treatments based on this key discovery are still years away, the results give scientists a key foundation on which to build future research.

Brief rapamycin therapy in middle-aged mice extends lives
In mice, the drug rapamycin is known to extend lives and delay some age-related problems. Questions remain about about how it promotes healthy aging, when, how much and how long to administer rapamycin, and how to avoid serious side effects. A new study showed brief therapy during middle age with rapamycin dramatically extended mouse lives. Findings revealed the need to further examine how gender and dose influence side effects and the drug's impact on susceptibility to and protection from different types of cancer.

Expecting the worst increases side-effects in breast cancer patients on hormone therapies
A study of women receiving hormone therapies such as tamoxifen as part of their treatment for breast cancer has found that the number and seriousness of side effects they experienced were influenced by their expectations. The study, published in Annals of Oncology, found that women who had higher expectations of suffering more and worse side-effects before their treatment began did, in fact, experience more after two years of adjuvant hormone therapy.
