Textbook Question
Chapter 9, Problem 2AC
Cancer cells divide out of control. Side effects of the cancer treatments chemotherapy and radiation therapy include loss of hair and of the intestinal lining, the latter producing severe nausea. What can you infer about the mechanisms of these treatments? What would you look for in an improved cancer therapy?

Describe one chemotherapeutic approach that can be used to treat prostate cancer? Your answer should include information about the molecular processes and interactions which are at the core of the treatment strategy
The growth fraction of the cancer types A 8, C, and D are 23%, 45%, 56%, and 78%, respectively. Which type of cancer is more suceptible
to the chemotherapy?
For many years, targeted therapies for cancer treatment continue to be developed, however more and more patients are developing resistance to targeted therapies. Discuss one mechanism of resistance to targeted therapies for cancer and provide an example of how might creatively combat it using clinical concepts.

- Discuss why certain cell types are less likely and others are more likely to develop cancer than others.arrow_forwardThis is a blank question. Thank you in advance, Bloom Syndrome Bloom syndrome is a rare genetic disorder. It is characterized by short stature and a long narrow face with prominent nose and ears. There is also increased sensitivity to light. People who have the disorder often develop rashes on their face, forearms, and hands when they have been exposed to the sun. In addition, these people often suffer from chronic obstructive pulmonary disorder (COPD) and have a higher chance of developing cancer. The cause of this genetic disorder is a mutation in the BLM gene located on chromosome 15. The immediate effect of this mutation is that there is a defect in the functioning of the DNA helicase enzyme. What would be the effect of this mutation on DNA replication? What stage of the cell cycle would be most affected?arrow_forwardBriefly summarize the conventional wisdom (DNA mutation theory) of the cause of cancer.

- Discuss why cancer treatment may involve a combinationof chemotherapy, radiation therapy, and surgery.arrow_forwardThe current way to gauge the effectiveness of chemotherapy is to track the size of the tumor. If the tumor shrinks, the chemotherapy is said to be "working." If cancer stem cells really do act the way we think they do, what will be the new way that the effectiveness of chemotherapy will be evaluated?arrow_forward"Cancer therapies directed solely at killing the rapidly dividing cells that make up the bulk of a tumor are unlikely to eliminate the cancer from many patients" is true or false.arrow_forward

Please list item by item. Explain in detail the main findings.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_forward
