Health Focus: Diabetes

Glucose is transported through the blood, powering cells throughout the body. However, if the level of glucose gets too high, it can cause the chronic problems associated with diabetes mellitus. Atomic structures have revealed how glucose levels are regulated in the body and are providing new hope for combating the disease. To learn more, browse PDB-101 resources related to diabetes.


2017 Video Challenge for High School Students: Molecular View of Diabetes Treatment and Management

In this video challenge, we would like you to focus on pharmacological treatments available for type 1 and type 2 diabetes and the common side effects of these treatments. Submit your video between March 7, 2017 and May 22, 2017. Learn more about the challenge, its timeline, the rules, and the resources.
