Epigenetic Regulation in Cancer Development
Quick fact
Epigenetic changes can be as important as genetic mutations in driving cancer, but unlike mutations, they are reversible—and that reversibility is the basis for a whole class of promising cancer drugs.
Why this is interesting
Every cell in your body has the same DNA, yet cells become muscles, neurons, or immune cells by reading different parts of the genetic script. So how can cancer arise not from mutations, but from cells mistakenly turning key genes on and off?
