You stimulated the cell with a ligand and analyzed the response. Upon ligand treatment, the cell increased the expression of gene α and decreased expression of gene β. When you inhibit cyclic AMP production by treating the cell with an inhibitor of Adenylyl cyclase, the increased expression of gene α was not observed but the decrease gene β expression was still observed. a) What you can expect for gene α regulation by this ligand? What signaling mechanism could be used? b) To determine how gene β is regulated by the ligand via what signaling mechanism, provide your hypothesis and indicate a potential experiment that you can perform to test that.
The above answer did not address the question in the sense that the answer did not indicate which protein involved in the pathways could be measured in the nucleus of cells and be confident in the results? I reiterate the question as follows: 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?
What type of signal transduction is involved in signaling from hormones such as estrogen and testosterone? Explain the signal transduction pathway that occurs. 1. Is there a short term description for signal transduction, instead wrting multiple words to descripte the type of signal transduction? Can I just identify it as active signal transduction and inactive signal transduction. Based on my understanding, active singal transduction is for the fast react transdcution, while inactive signal transduction meanly refers the hormonal affacts on the system. 2. For Ion channels, specific enzymes are both involed activated and inactivated signal transduction?
What are three types of signaling processes based on their transduction distance? Give an example for each type. What are the signaling molecules in the plant? Please describe each of them briefly.
What key role does signal transduction play in the signaling process?
The hypothesis for the experiment shown in the picture is that the TamC3 and TamR3 cell lines function, and grow the absence of estrogen, receptor function. Reduced reliance on estrogen, receptor signaling alters mTOR pathway activity. If this hypothesis is true, then mediators of mTOR signaling (Akt or p70S6K) should have reduced levels of phosphorylation. Where would you look to see this? Why does the data in the picture not support the hypothesis?
How could we promote rapid or slow signaling for medical purposes? So there are many examples of slow and rapid signaling via coupled receptors. For an example, salivary gland secretion is rapid signaling and cell growth is slow signaling. These pathways could be twisted and used to resolve medical issues in a more natural and less damaging way. Are there any experiments that have or could be done to test out promoting rapid signaling to speed up slow processes such as cell growth in a severe wound? What experiments have or could be done to test out slowing down signaling that is fast like cells responding to their environment negatively (over-active allergies)? Thank you.
Two protein kinases, barley kinase and hops kinase, function sequentially in an intracellular signaling pathway. If either kinase contains a mutation that permanently inactivates it, no response is seen in cells when an extracellular signal is received. A mutation that permanently activates barley results in a response even when there is no extracellular signal. You characterize a double mutant in which hops has the inactivating mutation and barley has the activating mutation. You observe that a response is seen in the double mutants even in the absence of an extracellular signal. In the normal signaling pathway, does barley phosphorylate hops or does hops phosphorylate barley? Briefly explain your answer.
Even when not considering the different molecular signaling mechanisms, how can the three main body axes be inferred by just primitive streak

Put the following steps for the outline of the growth factor signaling pathway in order: Map Kinase Kinase is Phosphorylated Proteins involved in gene transcription are activated Growth factor binds to its receptor in the cytoplasmic membrane Receptor recruits adaptor protein and GEF Autophosphorylation of tyrosine residues on the receptor Structural change of the receptor activates Tyrosine Kinase Map Kinase Kinase Kinase is phosphorylated Ras, a small GTPase, is activated by the exchange of GTP for GDP Map Kinase is Phosphorylated Map Kinase enters the nucleus
