Ancient Virus May Fuel Cancer Today
Relics of Primate Ancestors' Past
Scientists have discovered that an ancient virus that infected primate ancestors tens of millions of years ago may be playing a role in cancer development today. This finding stems from the observation of "flecks" of DNA left behind by the virus in the human genome.
Harnessing Ancient Immunity
Intriguingly, these ancient viral fragments have been found to assist the body in fighting cancer. The researchers believe that the immune system, which has evolved to recognize and defend against viruses, may inadvertently target cancer cells that contain similar viral DNA.
Potential Cancer Cause
However, the remnants of these ancient viruses may also pose a risk. The study suggests that under certain circumstances, these DNA fragments can become activated, potentially triggering or promoting cancer development.
Further Research Needed
The precise mechanisms by which these ancient viral fragments influence cancer are still being investigated. The researchers emphasize the need for further research to fully understand the implications of this discovery and explore potential therapeutic applications.
