More About PPAR-delta Activation in the Muscle Cell
The PPAR-delta receptor activates certain genes in a muscle cell, resulting in the burning of fat. This animation includes audio narration: please make sure your computer's volume is up so that you can hear it.
PPAR-delta Activation in the Muscle Cell Background PPAR-delta is one of a family of receptors that is related to the metabolism and storing of fat. Like PPAR-gamma, it also activates certain genes. However, PPAR-delta's activation signals the muscle cell to burn fat for energy. This led to the creation of a PPAR-delta-activated mouse, which can run significantly longer distances than regular mice, and which are more resistant to obesity.

PPAR-delta Activation in the Muscle Cell Teaching Tips
The animations in this section have a wide variety of classroom applications. Use the tips below to get started but look for more specific teaching tips in the near future. Please tell us how you are using the animations in your classroom by sending e-mail to biointeractive@hhmi.org.
- Use the animations to make abstract scientific ideas visible and concrete.
- Explain important scientific principles through the animations. For example, the biological clocks animations can be used to demonstrate the fundamentals of transcription and translation.
- Make sure that students learn the material by repeating sections of the animations as often as you think necessary to reinforce underlying scientific principles. You can start, restart, and play back sections of the animations.
- Urge students to use the animations in accordance with their own learning styles. Students who are more visually oriented can watch the animations first and read the text later, while others might prefer to read the explanations first and then view the graphics.
- Incorporate the animations into Web-based learning modules that you create to supplement your classroom curricula.
- Encourage students to incorporate the animations into their own Web-based projects.
