Cathepsin Cannibalism
Aug 14, 2012
Researchers for the first time have shown that members of a family of enzymes known as cathepsins - which are implicated in many disease processes - may attack one another instead of the bodily proteins they normally degrade. Dubbed "cathepsin cannibalism," the phenomenon may help explain problems with drugs that have been developed to inhibit the effects of these powerful proteases... Read More
Killing Prostate Cancer Cells Without Harming Other Healthy Cells
Aug 14, 2012
Experimenting with human prostate cancer cells and mice, cancer imaging experts at Johns Hopkins say they have developed a method for finding and killing malignant cells while sparing healthy ones. The method, called theranostic imaging, targets and tracks potent drug therapies directly and only to cancer cells... Read More
Daily Aspirin May Decrease Cancer Mortality
Aug 14, 2012
A large new observational study finds more evidence of an association between daily aspirin use and modestly lower cancer mortality, but suggests any reduction may be smaller than that observed in a recent analysis... Read More
How Iron Levels And A Faulty Gene Can Cause Bowel Cancer
Aug 13, 2012
HIGH LEVELS of iron could raise the risk of bowel cancer by switching on a key pathway in people with faults in a critical anti-cancer gene, according to a study published in Cell Reports*... Read More
Drugs May Help To Diagnose Undetectable Prostate Cancer
Aug 12, 2012
Researchers have successfully developed and tested a new prostate cancer screening method that uses the combined power of a novel drug therapy and changes in PSA levels over time to identify men with a high PSA who are more likely to have aggressive prostate cancer despite negative biopsies...

New Prostate Cancer Screening Test Shows Promise
Aug 11, 2012
According to a new study published in the Journal of Urology researchers at NewYork-Presbyterian Hospital and Weill Cornell Medical Center have successfully developed and tested a new prostate cancer-screening test... Read More
Using Heat As A Cancer Treatment
Aug 10, 2012
Research at Bangor University has identified a switch in cells that may help to kill tumors with heat. Prostate cancer and other localized tumors can be effectively treated by a combination of heat and an anti-cancer drug that damages the genes. Behind this novel therapy is the enigmatic ability of heat to switch off essential survival mechanisms in human cells... Read More
Significant Breakthrough Has Implications For Throat And Cervical Cancer
Aug 10, 2012
A major breakthrough by scientists at Queen's could lead to more effective treatments for throat and cervical cancer. The discovery could see the development of new therapies, which would target the non-cancerous cells surrounding a tumour, as well as treating the tumour itself... Read More
No Proven Benefit For PET And PET/CT In Ovarian Cancer
Aug 09, 2012
Only in certain cases are recurrences detected more reliably than with conventional techniques Due to the lack of studies, there is currently no proof that patients with ovarian cancer can benefit from positron emission tomography (PET) alone or in combination with computed tomography (CT)...

The Value Of Calcium And Vitamin D Supplements Questioned
Aug 09, 2012
Prescribing calcium and vitamin D supplements for men at risk of bone loss from hormonal treatment for prostate cancer seems like good medicine. But new research from epidemiologists at Wake Forest Baptist Medical Center showed that this type of supplementation did not prevent bone loss and, in fact, may increase the risk of cardiovascular disease and aggressive prostate cancer...
