Abstract

This case study follows a young cystic fibrosis (CF) patient named Lucas. Through Lucas's story and interactions between his parents and pediatrician, students learn about the scientific background and basis of CF. By reviewing email correspondence between Lucas's parents and various doctors, students gain an overview of CF research. CF has become a model disease in certain undergraduate biology classrooms due to its relatively clear mechanism and genetic basis. This case asks students to come up with their own ideas to improve on an existing line of research - gene therapy - in treating CF. During the process, students will gain a better appreciation of the innovative nature of science and develop research skills such as finding, understanding and analyzing primary literature. The activity was originally designed for first- and second-year students as part of an extracurricular case competition, but may be used for any undergraduate biology level. The case assumes basic (high school level) knowledge of genetics, biochemistry, cell biology and physiology.


Objectives

  • Describe the genetic and cellular basis of CF.
  • Describe the basic mechanism of gene therapy and its challenges.
  • Access, and derive meaning from, the scientific literature in order to identify further avenues of research to explore.
  • Summarize a selected area of CF research.
  • Demonstrate the creative and collaborative nature of scientific inquiry by working with peers to formulate original solutions within the given constraints.
  • Convey scientific information and ideas effectively in writing.
