How Does Epigenetics Explained | Penn Medicine Work?

Imagine your body is like a giant toy box, and epigenetics is like a special set of instructions that tell which toys get played with and which stay tucked away.

At Penn Medicine, scientists are studying these instructions to understand how our bodies work, and how things can go wrong, like when someone gets sick or grows old.

Like a Switch for the Toy Box

Think of your toy box as having switches on the outside. When you flip a switch up, it means the toys inside get played with more often. When you flip it down, those toys stay quiet and don’t come out so much.

Epigenetics is like flipping these switches, without changing the actual toys themselves. These switches can be turned on or off by things in our environment, like food, stress, or even the air we breathe.

How Penn Medicine Helps Us Understand

Scientists at Penn Medicine are like detective toy box watchers. They look closely at how these switches change over time and what happens when they're flipped, helping us understand diseases, aging, and even how to stay healthy for longer.

It's like having a special map that shows which toys should be played with more often, not by changing the toys, but by learning how to use the switches better!

Examples

  1. A child inherits a gene for tallness, but doesn't grow tall because the gene is switched off by epigenetics.
  2. A person eats too much sugar, and their body starts switching off genes that help with metabolism.
  3. Smoking changes how genes are turned on or off in lung cells.
