초록/해제  
요약During my dissertation in the lab of John Albeck, I have worked on various projects involving measurement of single-cell kinase signaling activity in response to stress using live-cell biosensors. This included optimizing and publishing methodology, the use of live-cell biosensors to measure cellular response to pro-inflammatory cytokines and oxidative stress, and the development of new biosensors. In Chapter 1, I introduce the methods we use to measure signal transduction in real time using fluorescent biosensors, which includes optimizations that I contributed to the lab. This protocol was accepted for publication as a chapter in Methods of Molecular Biology. In Chapter 2, with the help of my co-mentor Amir Zeki, I delve into the application of biosensors and show my finding that spatially coordinated ERK signaling (SPREADs) increased when airway epithelial cells are exposed to pro-inflammatory stimuli like those seen in common airway diseases. I then investigated the potential mechanisms of SPREADs and their suppression by hydrocortisone and metabolic stress that coincides with increased AMPK activity. Chapter 3 focuses on using live-cell microscopy to understand how the RNA-recognition motif of the translation protein eIF4B regulates the cell's ability to form stress granules and suppress protein synthesis following treatment with sodium arsenate. Finally, in Chapter 4, I discuss my work developing, validating, and optimizing Far-Red FRET biosensors for ERK (REKAR67 and REKAR76) and AMPK (RAMPKAR2). Including the use of RAMPKAR2 to understand the single-cell dynamics of AMPK, ATP:ADP ratio, and glycolysis. This last chapter includes work from two different publications in preparation for submission.
