For decades, the scientific community has known that inflammation, accelerated aging and cancer are somehow intertwined, but the connection between them has remained largely a mystery, Dr. Schneider said. What was known, due in part to past studies by Schneider and his team, was that a gene called AUF1 controls inflammation by turning off the inflammatory response to stop the onset of septic shock. But this finding, while significant, did not explain a connection to accelerated aging and cancer.
When the researchers deleted the AUF1 gene, accelerated aging occurred, so they continued to focus their research efforts on the gene. Now, more than a decade in the making, the mystery surrounding the connection between inflammation, advanced aging and cancer is finally being unraveled.
The current study reveals that AUF1, a family of four related genes, not only controls the inflammatory response, but also maintains the integrity of chromosomes by activating the enzyme telomerase to repair the ends of chromosomes, thereby simultaneously reducing inflammation, preventing rapid aging and the development of cancer
