Virtually all 37.2 trillion cells in our bodies have the same DNA, the spiraling molecule that contains the genetic instructions required to make us who we are. But if every cell works from the same playbook, how and why does the human body have so many different types of cells? Why do some become skin cells while others become muscle cells, heart cells or brain cells?

The answer is epigenetics — a complex set of processes that determine when and to what extent certain genetic instructions are carried out. Epigenetic processes are vital for healthy cellular function and, when things go awry, they can play major roles in disease.

Scientists in VAI’s Department of Epigenetics seek to understand how epigenetic changes may either protect us from or predispose us to complex diseases such as cancer, Parkinson’s and metabolic disorders. By investigating the epigenetic processes that fine-tune DNA, our scientists aim to pinpoint the origins of these complex diseases and determine how they are impacted by our past, present and future.
