Textbook Question
Chapter 11, Problem 12TYU
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.

ment for some forms of cancer.

induced?
A

с
D
by causing ribosomes to increase the rate of protein synthesis
by triggering the division of mitochondria in the cell to increase ATP production
by increasing the expression of membrane-bound glucose protein channels

RAS is a signal transducer that acts as a switch for turning on cell division. Drag the descriptions below to their proper places on the
figure to show the sequence of events.
When growth factor
binds to the receptor,
the intracellular domain
activates RAS by
facilitating exchange of
GDP for GTP.
When no growth factor
is bound to the
extracellular receptor,
RAS is bound to GDP
and is inactive.
RAS activates the
first of three
sequential kinase
proteins termed the
MAP kinase cascade.
Cell proliferation
proceeds as the
machinery for cell
division is set in
motion.
The end result of the
MAP kinase cascade
is activation of a
transcription factor.

- 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_forwardurgntarrow_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_forward

Describe some of these diseases in the table below:arrow_forwardDiagram (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_forwardCancer is a complicated series of diseases characterized by over-proliferation of cells within a tissue. While in some instances the primary tumor is the ultimate cause of death, in many cases the primary tumor metastasizes, or moves, through the lymph system to invade other tissues. The migration of tumor cells requires changes in the adhesion properties of the cell that allow it to move and invade more readily. There are several molecules involved in cell-to-cell connections and cellular architecture: laminins, matrix metalloproteinases, cadherins, and integrins. While mutations in genes that control the cell cycle or recognize DNA damage are the causes of tumor cell formation, tumor cell spread to other tissues may be caused by mutations in the genes the code for these extracellular proteins. The loss of cellular connections, cellular identification and signaling, and tissue structure may lead to the release of expanding tumor cells into the circulatory and lymphatic systems.

- Understand 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).

- 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.
