Cell Signaling

It allows cells to perform various cellular activities, coordinate, and interact with other cells. All cells of an organism receive signals from their environments and respond accordingly. Even the unicellular eukaryotes receive signals secreted by other cells and respond. In the case of yeast, mating takes place by signaling between the yeast cells. Communication by cell signaling in a multicellular organism has become a vast and important part of various fields of biology.

Help constructing a concept map? Example provided below. Many studies have indicated that autophagy and apoptosis play an important role in the pathogenesis of spinal cord injury. In recent years, research on autophagy-related signal transduction pathways has demonstrated that the phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway is closely associated with the initiation of autophagy. However, the mechanism of the pathological relationship between this signaling pathway and apoptosis in spinal cord injury is unclear. In this study, we used an in vitro model of spinal cord injury to observe the mechanism of the PI3K/Akt/mTOR signaling pathway and the apoptosis of neurons via the mitochondrial pathway. Mitochondrial pathway apoptosis-related proteins were detected by western blot. Akt and mTOR phosphorylation levels peaked 4 h after mechanical damage and then decreased. Following administration of the PI3K-specific…
EGF-R patho Discuss how the EGF-R becomes activeo How does the active receptor recruit substrate, and how does substrate hold ontoreceptor? When held, what “options” in regards to what the receptor does tobound substrate?o What proteins are involved in the recruitment of ras to the receptor, and how doesras become active – what does it do then? Make sure you include the G-proteinstory.o When active, ras triggers the MAPK cascade – what is the end result of this path.o Discuss the most common mutation in the ras gene found in cancer cells – how doesthis mutation play a role in the cancer cell story?
Part A (Short Response): You are developing a TGF-β agonist, but you don’t yet know which specific proteins it is signaling through. You want to do a single Western blot to measure changes in signaling activity, regardless of which pathway is being activated. For which protein involved in these pathways could you measure the levels in the nucleus of cells and be confident in your results? Why? This part was already posted on chegg, but I didn't understand the answer. I need a thorough explanation, so I can fully understand. Part B (Short Response): There have been many attempts to block TGF-β signaling in cancer through many different mechanisms, but none of been very successful. Why do you think this is? I know they have gotten close to being successful, but I don't know what preventing their success.
5. Explain the signaling steps that take place after the EGF receptor is dimerized, up to the poiunt when Ras gets activated. Draw a schematic to make it easier for your classmates to understand.6. Explain why the RTK signaling pathway includes the extra complication of having a protein (Ras) that switches between GTP- and GDP-bound states. PLEASE ANDWER BOTH
DRAW IT Draw the following apoptotic pathway, whichoperates in human immune cells. A death signal isreceived when a molecule called Fas binds its cell-surfacereceptor. The binding of many Fas molecules to receptorscauses receptor clustering. The intracellular regions of thereceptors, when together, bind proteins called adaptorproteins. These in turn bind to inactive molecules ofcaspase-8, which become activated and then activatecaspase-3. Once activated, caspase-3 initiates apoptosis.

), create a simple flowchart depicting the MC1R pathway. There should be a minimum of five steps in the pathway. Be sure to include reception (protein binding to its ligand), a portion of the transduction pathway (what’s the intracellular reaction? What molecule works intracellularly?), and the cellular response (What’s produced from the cell?).
Cell signaling The maximum secretion rates of proteins are one type of limiting constraint on signal-ing processes since a cell cannot send a signal faster than it can secrete it. These maximum signalingrates can be estimated with maximum rates of transcription and translation. Consequently, proteins withstrong promoters can be synthesized at much higher rates. Immunoglobulins, which are important signal-ing molecules, have very strong promoters. Their maximum secretion rate is on the order of 2000 to 8000antibody molecules/cell/second, which corresponds to approximately 1 pg/cell/hr. Part AWhat would be the maximum signal (in pg/cell/hr) that a cell could send for the following situations: (1)Signal molecule A has a MW = 100,000 daltons and is secreted at a rate of 1000 molecules/cell/second. (2)Signal molecule B has a MW = 50,000 daltons and is secreted at 5000 molecules/cell/second.Part BWhich molecule is secreted at a higher rate? By how much?Part CIf equivalent fluxes of both…
