AP Biology Research Project - Cell Signaling Diseases Project
INTRODUCTION
Communication between cells is important in order to ensure that all cells are performing their required functions. Cell
to cell communication usually takes the form of a signal transduction pathway. You can think of such a pathway as a row
of dominoes, all standing on their ends. Push one domino over, and the rest fall, due their direct or indirect association
with the first one you pushed over.
Some signals that cells send only work over a short distance. For example, in the brain, neurotransmitters allow one
neuron to excite its neighbor. The signal travels no further. Other signals, however, do travel a further distance.
Hormones, for example, are secreted by a source organ and travel to target cells, equipped with specialized receptors, in
remote regions of the body. Unfortunately, signal transduction might go awry. Because there are so many players and
so many steps in the process, it is easy to see how this might happen. To complete this project you will need to:
1. Review information about how problems in cell signaling can lead to diseases:
a. Explain the stages of a normal signal transduction pathway.
i. Understand the role of extracellular molecules (or ligands) in normal signal transduction.
ii. Recognize the role of protein kinases, cyclic AMP or calcium in the regulation of cellular
biochemical pathways in non-diseased cells.
iii. Describe what a cell does when it receives a signal (what kinds of cellular processes are altered
upon receipt of a signal)
b. Explain how the disease you have researched results from a disruption of this signal transduction
pathway (whether it be at reception, transduction or response)
2. Share this information in a visual and oral presentation
Your responsibility is to develop a poster that explains the basics of the disease and its relationship to a faulty
signal transduction pathway. Much of this research is "cutting edge." Your poster must explain both the
"normal" pathway and the "faulty" pathway and describe treatments and/or research being done for the
disease. Pictures and graphics are also necessary. I do not expect you to work at the graduate level on this
project but I do expect you to be able to explain, in your own words, the basics of the mechanism and the way in
which the failure of the mechanism leads to disease.

1. Format - poster - 10 points
• All information must be typed; use headings and appropriate font sizes
• Pictures and graphics included; at least three including
o A picture or drawing of a person with the disease or a picture or drawing of
organs and/or tissues affected by the disease.
o A picture or drawing of the normal, working cell signaling pathway(s)
involved.
o A picture or drawing of the faulty cell signaling pathway(s) involved.
• Neat/colorful presentation - no spelling or grammatical errors
• Include name(s) in lower right corner of poster

poster
2. Content - 16 points
