Compare and contrast signal transduction via tyrosine kinase
receptors, G-protein receptors, and the IP3/DAG receptor pathways.
Explain how it is possible for a primary messenger to illicit more
than one response depending on the cell receiving the signal. In
other words, how is it that increasing the concentration of one
hormone can activate pathways in some tissues and activate or
inhibit pathways in other tissues?
Signal transduction refers to any process of changing one signal
to signal of another type. An example would be a series of pulsing
lights into the sound for the word: "Help". Discuss how this
transduction could be done by a device.
Signal Transduction:
A) Explain how growth factors, acting through the signal
transduction pathway, regulate cell
proliferation. Names of specific proteins and their
function must be given.
B) Give 2 specific examples of how an alteration in the signal
transduction pathway can lead to cancer
Cell Cycle Regulation:
Describe the mechanism by which the cell cycle is regulated by
mitogens. In your answer, be sure to include the following:
a) The phases of the cell cycle and protein whose concentrations
vary during...
