Classes 7-8 Cytoplasmic Growth Signaling Be able to describe Ras structure and function. What kind of protein is it? How is it regulated (Fig. 5.30)? How many forms of Ras do humans express? Be able to describe how Ras interacts with multiple downstream partners. What mechanisms render ras oncogenic? Also, how does Ras become oncogenic in the absence of ras mutations? Be able to describe how Ras interacts with the growth factor receptor signaling machinery. How did fly genetics help...
How can a signaling molecule be interpreted in different ways by cells in the body?
29. Consider the following LAN with one Ether switch S, one intra-domain router R, and two hosts X and Y Assume switch S has been just powered on. 1. Describe the routing and address resolution steps performed at X, Y, and S when X sends an IP packet to Y. 2. Describe the routing and address resolution steps performed at X, Y, and S when Y replies an IP packet to X. 3. Describe the routing and address resolution steps...
Describe how a single protein in the tyrosine kinase signaling pathway possesses all the protein functions that characterize signal transduction.
What is the difference between graded and discrete signaling? Describe three ways in which signals may be combined to convey different meanings.
7. Describe correct handwashing technique. When must handwashing be performed?
related to insulin signaling This is related to insulir cell signaling 1) Describe the steps between the binding of an insulin molecule at the surface and the activation of the effector PI3K of the target cell 2) How does the action of the insulin receptor differ from other ligands that act by means of receptor tyrosine kinases? 3) What is the relationship between type 2 diabetes and insulin production? How is it that a drug that increases insulin sensitivity might...
Growth factor signaling through receptor tyrosine kinases (RTKs) results in multiple phenotypic changes. These changes are elicited in part by RTK activation of distinct yet specific intracellular signaling pathways. Describe the mechanism whereby a growth factor leads to the activation of several different yet specific pathways, and how that specificity is achieved. Begin with the growth factor and end with activation of the different intracellular signaling pathways. You must be comprehensive in your answer. Answer in no more than six...
Problem Five One of the transducers in many growth factor signaling cascades is ras. a) How can mutations in ras (found in some types of cancers) contribute to transforming a normal cell into a tumor cell? b) Describe how ras plays a role in MAPK signaling pathways.
