A switch in cells that help kill prostate tumors with heat has been discovered by scientists.
Prostate cancer and other localized tumours 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. Although thermotherapy is now more widely used, the underlying principles are still unclear.
"The discovery is reminiscent of a Russian doll were a set of smaller wooden figures is placed inside a larger doll. The existence of such hidden genes may explain why the human genome has a much smaller number of genes than initially expected," leader of the Genome Biology group, Dr Thomas Caspari said.
"Our work may also help to improve heat-treatment of cancer for the benefit of patients. This research success was a real team effort made possible by the generous funding from Cancer Research Wales and the European Leonardo DaVinci Program," he added.
The study was recently published in the Journal of Cell Science.
