- What separates cancer cells from normal cells? Describe one form of mutation that can increase the risk of a normal cell being cancerous.The 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?Although cancer is not a contagious disease in humans or other vertebrates, there have been rare cases in which cancers have spread from one organism to another. Describe three cases of these contagious cancers and what conditions might have led to their appearance. For an introduction to this topic, see http:// www.cancer.org/cancer/cancerbasics/is-cancer-contagious.
- Metastasis occurs when cells from a primary tumor invade and colonize other tissues. Metastasis is a complex, multistep process. Tumor cells must lose adhesion with other tumor cells, invade local tissues and vessels, move through the circulation, leave the vessels, and finally, establish new colonies at distant sites. Tumor cells gain the ability to cross epithelial layers and migrate through tissues by mutations, although the nature of the mutations that drive metastasis is poorly understood. Mutations that block expression of the E-cadherin gene are thought to be an important step in metastasis. The absence of E-cadherin expression could affect metastasis by blocking cell adhesion directly, by releasing signaling proteins bound to the cytoplasmic domain of E-cadherin, or by both mechanisms. To better understand how loss of E-cadherin contributes to metastasis, scientists created two cell lines that differed in their expression of E-cadherin. One cell line was blocked for expression…Which of the following mutations is MOST likely to cause cancer? A) a mutation that causes a cyclin gene to be expressed at all times during the cell cycle B) a mutation that causes an oncogene to be turned off so that no protein is made C) a mutation that causes a Cdk gene to be turned off so that no protein is made D) a mutation that causes a tumor suppressor gene to be over-expressedWhich of the following effectively describes the situation of someone with an inherited predisposition to cancer such as familial adenomatous polyposis or BRCA-associated familial breast cancer? Choose all that apply a) If they get malignant cancer, somatic mutations will not have been a factor b) Their cancer will most likely arise in their germ cells, not their somatic cells c) None of the answers effectively describes the situation d) Every cell of their body contains a gain-of-function allele of an oncogene e) Most cells in their body contain multiple cancer-causing mutations f) Every cell of their body contains a defective, loss-of-function allele of a tumor suppressor gene
- Benign tumors: a. are noncancerous growths that do not spread to other tissues b. do not contain mutations c. are malignant and clonal in origin d. metastasize to other tissues e. none of theseWhy would the failure of the p53 tumor supressor gene be more likely to cause cancer in a seventy year old person compared to a ten year old person? Group of answer choices A) The seventy year old is more likely to have pre-existing failures in cell cycle control B) cells divide more rapidly as people get older C) there are fewer mutations in genes controlling the cell cycle in older people D)the p53 gene never works well in old peopleone question with multiple parts! 1A) If you were a cancer biologist interested in developing new drugs that will slow down cancer cell metastasis, which of the following strategies would be most effective? a)Develop an activator of mitosis b)Make Her2 protein that is more active on the surface of the cancer cells c) Develop a molecule that increases telomerase activity d) Gene therapy to add a mutated p53 gene to the cancer cells 1B) You are a genetic counsellor, and a couple comes to you with concerns that if they have a child together the child could have the X-linked recessive disease Duchene muscular dystrophy. The man has the disease whereas the woman is a carrier. Which of the following would be a true statement to tell them? a) 100% of their male offspring will likely be carriers of the recessive allele that causes the disease b) 75% of their female offspring will likely be carriers of the recessive allele that causes the disease c) 100% of their male offspring will likely…
- Why is p53 considered a tumor suppressor protein? Question 12 options: a) Because p53 normally detects breaks in DNA. b) Because p53 normally causes progression from G1 to S phase to halt until damaged DNA is fully repaired. c) Because p53 normally repairs breaks in DNA. d) Because p53 normally stimulates transcription of Repair Polymerase. e) Because p53 normally reduces the mutation rate of DNA polymerase.The "initiation" stage of cancer refers to: a) The stage where DNA is mutated, and permanent DNA damage occurs b) The stage during which the mutated cells develop into a malignant cell population c) The stage during which "promoters" enhance the further development of the mutated cells d) The stage during which cancer breaks away from the primary origin and metastasizesWith regard to cancer cells, which of the following are true? A. Cancer cells are clonal, meaning that they are derived from many different cells that all underwent the same clonal mutation. Cells usually accumulate many mutations over time, and this results in cancerous growth. B. Almost all cancers are caused by oncogenic viruses. no Benign tumors are dangerous because they can easily invade surrounding tissue and spread to other locations in the body. DE. Cancer cells are unable to control their division.
