Scientists Discover How To Reactivate Cancer’s Dormant “Kill Switch”
Ovarian cancer presents late. The peak incidence is at age 75 which is about 10 years later than most cancers. Theories about why this is so suggested that there is a period of dormancy, and that the cancer becomes overt because of some unexplained change.
This research suggests that many aggressive and hard to treat cancers including ovarian cancer hijack normal protective functions that would otherwise limit cancer invasion. This protective mechanism limits cellular metabolism by blocking DNA and RNA transcription,with consequent reduction in enzyme and protein activity which would otherwise promote cancer growth.
When this process is hijacked, the protection is lost. This research suggests that the protective mechanism can be restored using synthetic RNA fragments to alter cellular metabolism.
This discovery has the potential to provide a new target for precision therapy by restoring cancer dormancy.
