Researchers describe a novel mechanism by which glioblastoma tumors resist targeted therapies A Ludwig Cancer Research study has uncovered an entirely novel mechanism by which glioblastoma (GBM), the most common kind of brain cancer, evades targeted therapies. Published in the current issue of the journal Science, the paper describes how GBM tumor cells essentially hide the signaling molecule targeted by such therapies, adding a layer of complexity to current models of drug resistance in...

Study Finds Drug-Resistant Melanoma Treatments May Be Enhanced
2013-11-22 09:27:11

April Flowers for redOrbit.com - Your Universe Online More than 8,000 Americans are killed each year by melanoma -- the deadliest form of skin cancer. The presence of mutations in a gene known as the BRAF gene drives approximately 40 percent of advanced melanoma tumors. New medications, called BRAF inhibitors, have shown an ability to rapidly shrink melanoma tumors, however BRAF-mutated tumors often resist early treatment and only partially respond to BRAF inhibitors, which leaves...

EPFL researchers have shown that copper is essential for the energy production of malignant cells, and that reducing its intake via food and water can slow down tumor growth Copper imbalances have been associated with a number of pathological conditions, including cancer. Publishing in PNAS scientists at EPFL have found that copper in drinking water – given at the maximum levels permitted in public water supplies – accelerated the growth of tumors in mice. On the other hand, reducing...

New Driver Of Breast Cancer Discovered

UT Southwestern Medical Center A team of researchers at UT Southwestern has found that as cholesterol is metabolized, a potent stimulant of breast cancer is created – one that fuels estrogen-receptor positive breast cancers, and that may also defeat a common treatment strategy for those cancers. The multidisciplinary team discovered that a cholesterol metabolite called 27-hydroxycholesterol, or 27HC, promotes tumor growth in estrogen-receptor positive breast cancers, which are the...

Genetic Pathway Could Be New Target For Pediatric Tumor Treatment
2013-11-07 11:27:12

redOrbit Staff & Wire Reports - Your Universe Online Low-grade gliomas – a type of pediatric brain tumor that is difficult to care for medically – could potentially be treated using a known genetic pathway, according to new research published in Thursday’s edition of the journal Neuro-Oncology. In laboratory studies, Dr. Fausto Rodriguez, assistant professor of pathology and oncology at Johns Hopkins, and colleagues reported that the mammalian target of the rapamycin (mTOR)...

Transferring the gut microbes from a mouse with colon tumors to germ-free mice makes those mice prone to getting tumors as well, according to the results of a study published in mBio®, the online open-access journal of the American Society for Microbiology. The work has implications for human health because it indicates the risk of colorectal cancer may well have a microbial component. "We know that humans have a number of different community structures in the gut. When you think about...

Study confirms that vascular normalization is the way these drugs improve patient survival Advanced imaging techniques may be able to distinguish which patients' tumors will respond to treatment with anti-angiogenic drugs and which will not. In patients newly diagnosed with the dangerous brain tumor glioblastoma, Massachusetts General Hospital (MGH) researchers report, those for whom treatment with the anti-angiogenic drug cediranib rapidly 'normalized' abnormal blood vessels around their...

May Be Able to Recreate Conditions That Keep Cancer Cells from Growing after They Have Spread New York, NY (PRWEB) October 27, 2013 Oncologists have long puzzled over the fact that after cancer treatment, single cancer cells that are dispersed throughout the body – so-called disseminated tumor cells – are quick to grow and form secondary tumors called metastases in certain organs, while in other organs they metastasize more slowly, sometimes decades later. Such is the case with head...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
