Investigative Case 10:  SHH- Silencing the Hedgehog Pathway

Open-Ended Investigations

To learn more about the hedgehog pathway, you could explore the Hedgehog Pathway Signaling Database (Ramirez-Weber, 2006), which contains relevant information, images, and references to research articles. You may wish to form a group to develop a proposal for a new investigation. For example:

Note: Your instructor could set up a proposal peer review process in your class, simulating what is done by major funders such as the National Science Foundation and the National Institutes of Health.
