IU research finds link between molecular mechanisms in prostate cancer and Ewing's sarcoma
Medical researchers at Indiana University have found evidence for a link between prostate cancer, which affects millions of men age 50 and older, and Ewing's sarcoma, a rare form of cancer that affects children and young adults. The results appear in the journal Cell Reports.

Terminally ill cancer patients fare poorly after surgery
Patients with disseminated advanced cancer who undergo surgery are far more likely to endure long hospital stays and readmissions, referrals to extended care facilities and death, UC Davis researchers have found.

A new look at vitamin D challenges the current view of its benefits
It's widely accepted that vitamin D is good for bones. But what if it plays a much larger role in health than is currently accepted? Recent research at the Buck Institute points in that direction -- at least in the nematode worm. The study shows vitamin D works through longevity genes and impacts processes associated with many human age-related diseases. The research is prompting some clinicians to call for universal vitamin D supplementation.

Quantum leap in the reliability of mass spectrometry-based proteomics
Modern mass spectrometry systems enable scientists to routinely determine the quantitative composition of cells or tissue samples. However, different analysis software packages often produce different results from the same raw data. An international team of researchers led by Professor Stefan Tenzer from the Mainz University Medical Center has now addressed this problem by comparing and modifying various analysis software packages to ensure that the different software solutions produce consistent results.

Study indicates that advances in precision medicine have improved breast cancer treatment
A new study examines how one early example of precision medicine -- tumor genome testing -- is being used in women with breast cancer to reduce overtreatment and maximize the benefits of chemotherapy. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the study found that physician recommendations and final treatment decisions correlated highly with test results, suggesting genome testing helped physicians identify which patients could most benefit from chemotherapy, and those for whom chemotherapy could be safely omitted.

What proportion of cancer deaths are attributable to smoking around the US?
The proportion of cancer deaths attributable to cigarette smoking varied across the United States but was highest in the South, where nearly 40 percent of cancer deaths in men were estimated to be connected to smoking in some states, according to a new article published online by JAMA Internal Medicine.

New guideline on calcium and vitamin D supplementation

Genetic hallmarks of acute lymphoblastic leukemia subtype uncovered
An international team of researchers from the St. Jude Children's Research Hospital - Washington University Pediatric Cancer Genome Project (PCGP) and the Children's Oncology Group (COG) has identified the genetic changes that underpin a subtype of the most common cancer found in children. This form of B-precursor acute lymphoblastic leukemia (B-ALL) features genetic changes to two transcription factors known as DUX4 and ERG, proteins that closely control the activities of other crucial genes in human blood cells.

Study suggests that autophagy inhibitors could improve efficacy of chemotherapies

Boosting levels of known antioxidant may help resist age-related decline
Researchers have found that a specific detoxification compound, glutathione, helps resist the toxic stresses of everyday life -- but its levels decline with age and this sets the stage for a wide range of health problems. It may be possible to restore glutathione levels and help prevent some of the metabolic declines associated with aging.

A key to unlocking the mystery of triple negative breast cancer
The study suggests screening breast cancer patients for the prolactin receptor could improve the prognosis for patient and may help them avoid unnecessary and invasive treatments. The researchers found that prolactin hormone was able to reduce the aggressive behavior of cancerous cells. It does so by decreasing their ability to divide and form new tumors.

Fighting cancer with the power of immunity
Researchers at MIT's Koch Institute for Integrative Cancer Research have developed a new strategy for using immunotherapy to treat cancer. The researchers used a combination of four different therapies to activate both branches of the immune system, producing a coordinated attack that led to the disappearance of large, aggressive tumors in mice.

Discovery of blood biomarkers for early pancreatic cancer detection
Pancreatic cancer is one of the most lethal forms of cancer. Early detection is essential to improve prognoses. Working toward that goal, a collaboration of researchers in Japan has discovered proteins in the blood which improve the detection of pancreatic cancer. When used in combination with conventional pancreatic cancer biomarkers, it enables the diagnosis of early stage pancreatic cancer, which was previously thought to be difficult.

A new view of the immune system
Pathogen epitopes are fragments of bacterial or viral proteins. Nearly a third of all existing human epitopes consist of two different fragments. Known as 'spliced epitopes', these types of epitopes have long been regarded as rare. The fact that they are so highly prevalent might, among other things, explain why the immune system is so highly flexible. Results from this study have been published in the current issue of the journal Science.*

Combating drug resistance in acute myeloid leukemia with a ceramide-based therapeutic
Researchers at the Medical University of South Carolina Hollings Cancer Center have discovered a mechanism that confers resistance to drugs used to treat certain types of acute myeloid leukemia. Targeting this pathway with a novel lipid-based therapeutic showed efficacy in a preclinical model of AML. These findings were reported in an article published in the Oct. 13, 2016 issue of Blood.

Where does cisplatin bind?
Cisplatin is one of the most widely used agents in cancer chemotherapy. It cross-links DNA, which can kill cells. But which part of the genome is more affected, and which is less affected? A Chinese team have now set up a universal, genome-wide assay to detect the specific cisplatin action sites. In the journal Angewandte Chemie they report initial results, which support the notion that the mitochondrial genome is one of cisplatin's main targets.
