“When there is DNA damage, it rushes onto the scene and stops your cells from dividing so the DNA can be repaired,” Dr. Joshua Schiffman, a pediatric oncologist at the Huntsman Cancer Institute in Salt Lake City and a senior author of the study said. He explained also the vulnerability that humans have: humans inherit one allele of TP53 from each of their parents, and both of them must be functional to fight off cancer; studies show that if one of the alleles is defective, cancer is certain to develop sooner or later. What can I do to benefit of this scientific discovery ? The researchers believe that reinforcing the protection offered by TP53 would be enough to prevent our own cells from becoming cancerous. They hope to create a drug that mimics the actions of TP53 and even imagining other possibilities.
