WRITE ABOUT A THEME: ORGANIZATION The properties of life emerge at the biological level of the cell. The highly regulated process of apoptosis is not simply the destruction of a cell; it is also an emergent property. Write a short essay (about 100–150 words) that hriefly explains the role of apoptosis in the development and proper functioning of an animal, and describe how this form of programmed cell death is a process that emerges from the orderly integration of signaling pathways.

- Figure 9.8 HER2 is a receptor tyrosine kinase. In 30 percent of human breast cancers, HER2 is permanently activated, resulting in unregulated cell division. Lapatinib, a drug used to treat breast cancer, inhibits HER2 receptor tyrosine kinase autophosphorylation (the process by which the receptor adds phosphates onto itself), thus reducing tumor growth by 50 percent. Besides autophosphorylation, which of the following steps would be inhibited by Lapatinib? Signaling molecule binding, dimerization, and the downstream cellular response. Dimerization, and the downstream cellular response. The downstream cellular response. Phosphatase activity, dimerization, and the downsteam cellular response.arrow_forwardThe best strategy for treating a specific type of human tumor can depend on identifying the type of cell that became cancerous to give rise to the tumor. For some tumors that have colonized a distant location (metastasized), identifying the parental cell type can be difficult. Because the type of IF protein expressed is cell-type-specific, using monoclonal antibodies that react with only one type of IF protein can help in this identification. What IF proteins would you produce monoclonal antibodies against to identify (a) a sarcoma of muscle cell origin, (b) an epithelial cell carcinoma, and (c) an astrocytoma (glial cell tumor)?arrow_forwardGive typed explanationarrow_forward
- Diagram (just use arrows in the same way you diagrammed in a former test a stimulus leading to the activation of PKC, for example) in as much detail as possible what happens to a mammalian cell when it is irradiated, leading to when the cycle stops due to DNA damage. Include and name the famous mammalian checkpoint protein known by its molecular weight, as well as name another protein it activates. This other protein's function can be described by a 3 letter acronym that contains the letter K. Mention the acronym. 1.arrow_forwardDescribe the steps of the signal transduction pathway for the cancer cells of today's Learn About It and Try It.arrow_forwardUnderstand how a cancer cell from a primary benign tumor is able to leave the primary benign tumor and enter the blood stream or lymph (migration), start to adhere and grow in a nearby environment like a blood vessel near an organ (invasion) and enter into a new organ to grow and form a secondary tumor ( extravasation). What proteins would be involved in these steps and what molecular changes in the ECM or basal lamina would need to occur as well as the cancer cell for this process to happen.arrow_forward
- Many common medications function by interrupting the normal operation of certain signal transduction pathways. Which of the following describes a possible mechanism by which a certain medication may interrupt a signal transduction pathway? A A medication enters the target cell and triggers apoptosis by causing the release of di- gestive enzymes from cell lysosomes. B A medication interacts with the phospholipid bi-layer of the cell membrane and in- creases its permeability. с D A medication binds to membrane-bound glucose proteins and acts as an allosteric in- hibitor that prevents the intake of glucose by the cell. A medication diffuses through the membrane of a target cell and inhibits an enzyme that normally synthesizes a second messenger.arrow_forwardA current focus of molecular medicine is to trigger or promote apoptosis of specific cells. several components of the apoptotic pathways are being targeted using this approach. for following, state specifically how the treatment would be expected to stimulate or inhibit apoptosis. c. Treatment of cells with organic compounds that enter the cell and bind with high affinity to the active site of Caspase-3arrow_forwardWhich of the following could result in the continuous activation of a cell signalling pathway? A mutation resulting in the inactivation of a protein phosphatase. A mutation resulting in the inactivation of adenylyl cyclase that forms cAMP. A mutation resulting in a receptor tyrosine kinase being unable to form a dimer. A mutation resulting in a ligand gated ion channel being unable to open.arrow_forward
- cells undergo programmed cell death. Write out the pathway(s), noting the changes (e.g., localization, phosphorylation, activation) When mammalian cells are irradiated, they stop dividing by arresting at cell cycle checkpoint. If the damage persists, the kinase (CdK), Cdk inhibitor, cytochrome c, DNA damage, mitochondria, p53, phosphorylation, transcription. each step.
