Urging HPV vaccine for boys could protect more people at same price
Whether vaccinating US boys against HPV in addition to girls is worth the cost has been hotly debated. But with HPV-related cancers in men on the rise, and coverage in girls stagnating below the levels needed to ensure that most people are protected, research suggests that devoting a portion of HPV funding to boys -- rather than merely attempting to improve female coverage -- may protect more people for the same price.

'Quantum jitters' could form basis of evolution, cancer
Duke researchers have discovered 'quantum jitters,' in which DNA's four basic building blocks temporarily change shapes, fooling DNA-replication machinery into making a copying mistake. This shape-shifting is exceedingly rare and only flickers into existence for a thousandth of a second. But these jitters occur with the same frequency as DNA copying mistakes, a hint that this might be the basis of the genetic mutations that drive evolution and diseases like cancer.

Molecules in prostate tumors might predict whether RT can help prevent recurrence
A new study has identified a group of molecules in prostate-cancer cells that doctors might one day use to distinguish which patients should be treated with radiation therapy if rising PSA levels indicate their cancer has recurred after surgical removal of the prostate.

Deadly to cancer cells only
Parvoviruses can destroy cancer cells and are currently being tested in a preliminary clinical trial to treat malignant brain cancer. For their replication, the viruses need a particular enzyme in the cell. Scientists from the German Cancer Research Center have now discovered that in healthy human cells, parvoviruses are unable to activate this enzyme. In many cases of malignant brain cancer, however, the enzyme is permanently active. As a result, this enables the viruses to replicate and to destroy the cancer cells.

Honey, I shrunk the ants: How environment controls size
Until now scientists have believed that the variations in traits such as our height, skin colour, tendency to gain weight or not, intelligence, tendency to develop certain diseases, etc., all of them traits that exist along a continuum, were a result of both genetic and environmental factors. But they didn't know how exactly these things worked together. By studying ants, McGill researchers have identified a key mechanism by which epigenetic factors influence the expression of all of these traits.

Scientists show proteins critical in day-night cycles also protect cells from mutations
New research from The Scripps Research Institute shows that two proteins critical for maintaining healthy day-night cycles also protect against mutations that could lead to cancer. The new study shows that the two proteins have an unexpected role in DNA repair, possibly protecting cells from cancer-causing mutations triggered by UV radiation.

Regenstrief study finds natural language processing accurately tracks colonoscopy quality
An accurate system for tracking the quality of colonoscopies and determining the appropriate intervals between these procedures could contribute to both better health outcomes and lower costs. Clinician-researchers from the Regenstrief Institute have created and tested such a system in the nation's first multiple institution colonoscopy quality measurement study utilizing natural language processing and report that it is as accurate but less expensive than human review.

Childhood leukemia study reveals disease subtypes, new treatment option
A new study of acute lymphoblastic leukemia (ALL), a blood cancer that primarily affects young children, has revealed that the disease has two distinct subtypes, and provides preliminary evidence that about 13 percent of ALL cases may be successfully treated with targeted drugs that have proved highly effective in the treatment of lymphomas in adults.

Radiation plus immunotherapy combo revs up immune system to better attack melanoma, Penn study suggests
Treating metastatic melanoma with a triple threat --including radiation therapy and two immunotherapies that target the CTLA4 and PD-1 pathways -- could elicit an optimal response in more patients, one that will boost the immune system's attack on the disease, suggests a new study from a multidisciplinary team of researchers from Penn's Abramson Cancer Center published today in Nature.

Cancer-linked protein helps control fate of intestinal stem cells
An international group of researchers has shown that a regulatory protein involved in controlling how cancer spreads through the body also influences the fate of stem cells in the intestine of mice. The results show that the Snai1 protein plays an important role in deciding the fate of intestinal stem cells and the different functions that these cells can adopt.

Innovative light therapy reaches deep tumors
Using a mouse model of cancer, researchers at Washington University School of Medicine in St. Louis have devised a way to apply light-based therapy to deep tissues never before accessible. Instead of shining an outside light, they delivered light directly to tumor cells, along with a photosensitive source of free radicals that can be activated by the light to destroy cancer. And they accomplished this using materials already approved for use in cancer patients.

African-American cancer patients' depression symptoms under-recognized, CWRU study finds
Case Western Reserve University nurse scientist Amy Zhang, who has long examined quality-of-life issues in cancer patients, wondered whether depression in African-American cancer patients has been under-recognized for treatment.Accurately assessing depression in cancer patients is difficult in general because the physical symptoms of cancer and depression -- low energy, lack of sleep and loss of appetite -- are so similar.

Researchers map 'genomic landscape' of childhood adrenocortical tumors for the first time
In an advance that could lead to better identification of malignant pediatric adrenocortical tumors, and ultimately to better treatment, researchers have mapped the 'genomic landscape' of these rare childhood tumors. Their genomic mapping has revealed unprecedented details, not only of the aberrant genetic and chromosomal changes that drive the cancer, but the sequence of those changes that trigger it.

Viagra in combination with new drugs can have anti-cancer, antibacterial, and therapeutic effects
Chaperone proteins play an important role in protein folding in human cells and in bacteria and are promising new targets for drugs to treat cancer and Alzheimer's disease and for novel antiviral drugs and antibiotics. How existing drugs such as Viagra or Cialis and a derivative of the drug Celebrex, for example, can reduce the activity of a specific chaperone protein, with the potential for anti-tumor and anti-Alzheimer's disease effects, is described in a Review article in DNA and Cell Biology.
