Researchers unveil new gene subgroup in prostate cancer
(University Health Network) Prostate cancer researchers have drawn a molecular portrait that provides the first complete picture of localized, multi-focal disease within the prostate and also unveils a new gene subgroup driving it. The discoveries, published online today in Nature Genetics, are a further step along the road to personalizing prostate cancer medicine say study co-leads, Dr. Robert Bristow, a clinician-scientist at Princess Margaret Cancer Centre, and Dr. Paul Boutros, an investigator at the Ontario Institute for Cancer Research.

'Pain sensing' gene discovery could help in development of new methods of pain relief

Complex signaling between blood and stem cells controls regeneration in fly gut
(Buck Institute for Age Research) Having a healthy gut may well depend on maintaining a complex signaling dance between immune cells and the stem cells that line the intestine. Scientists report significant new insight into how these interactions control intestinal regeneration after an infection. It's a dance that ensures repair after a challenge, but that also goes awry in aging fruit flies. The work offers important new clues into possible causes of age-related human maladies, including IBS and colorectal cancer.
