- Mammography is an accurate screening technique for the earlydetection of breast cancer in humans. Because this techniqueuses X rays diagnostically, it has been highly controversial. Canyou explain why? What reasons justify the use of X rays for sucha medical screening technique?Among the most prevalent pathologies that afflicthuman beings is heart disease, which can have a severeimpact on quality of life and can even result in prematuredeath. While heart disease mostly afflicts those who areolder, 1% or 2% of people in their 30s, and even in their20s, suffer from this disease. Genetic and environmentalcomponents of this disease exist. What strategy mightyou use to choose families to participate in a GWAS ofheart disease–causing genes? Explain your reasoning.Our government has finite funds to devote to cancer research.Discuss which of the following areas of research you think shouldreceive the most funding.A. Identifying and characterizing oncogenes and tumorsuppressorgenesB. Identifying agents in our environment that cause cancerC. Identifying viruses that cause cancer D. Devising methods aimed at killing cancer cells in the bodyE. Informing the public of the risks involved in exposure tocarcinogensIn the long run, in which of these areas would you expect successfulresearch to be the most effective in decreasing human mortalitydue to cancer?
- Why are cancers considered to be clonal in origin? OA. They are considered clonal in origin because they usually start out as a group of cells that undergoes mutation to lose control of cell division. OR They are considered clonal in origin because they have been important in the biotechnology industry for cloning genes. A They are considered clonal in origin because they usually are used in cloning experiments in laboratories that study cancer. OC. O D.hey are considered clonal in origin because they usually originate as a single cell that has acquired sufficient mutations to become cancerous. The description of "clonal" is actually a term coined by someone who really liked the Star Wars movies.If your father were diagnosed with an inherited disease that develops around the age of 50, would you want to be tested to find out whether you would develop this disease? If so, when would you want to be tested? As a teenager or sometime in your 40s? If not, would you have children?Studies have shown that there are significant differences in cancer rates among different ethnic groups. For example, the Japanese have very high rates of colon cancer but very low rates of breast cancer. It has also been demonstrated that when members of low-risk ethnic groups move to high-risk areas, their cancer risks rise to those of the high-risk area. For example, Japanese who live in the United States, where the risk of breast cancer is high, have higher rates of breast cancer than do Japanese who live in Japan. What are some of the possible explanations for this phenomenon? What factors may explain why the Japanese have higher rates of colon cancer than do other ethnic groups?
- Some germ-line mutations predispose individuals tocancer, yet often environmental factors (chemicals,exposure to radiation) are considered major risks fordeveloping cancer. Do these views of the cause ofcancer conflict, or can they be reconciled?Skin cancer carries a lifetime risk nearly equal to that of allother cancers combined. Following is a graph [modified fromK. H. Kraemer (1997). Proc. Natl. Acad. Sci. (USA) 94:11–14]depicting the age of onset of skin cancers in patients with orwithout XP, where the cumulative percentage of skin cancer is plotted against age. The non-XP curve is based on 29,757 cancerssurveyed by the National Cancer Institute, and the curverepresenting those with XP is based on 63 skin cancers from theXeroderma Pigmentosum Registry.Many human cancers result when a normal gene mutates and leads to uncontrolled growth (a tumor). Genesthat cause cancer when they mutate are called oncogenes. Chemotherapy is effective against many tumorsbecause it targets rapidly dividing cells and kills them.Unfortunately, chemotherapy has many side effects,such as hair loss or nausea, because it also kills many ofour normal cells that are rapidly dividing, such as thosein the hair follicles or stomach lining.Many scientists and large pharmaceutical companiesare excited about the prospects of exploiting theRNAi pathway to selectively inhibit oncogenes in lifethreatening tumors. Explain in very general terms howgene-silencing therapy might work to treat cancer andwhy this type of therapy would have fewer side effectsthan chemotherapy
- ames has conducted an occupational cohort study. He has studied coal miners and their rates of cancer, and has compared them to steel workers, and their rates of cancer. There were 50 coal miners and 20 steel workers. 25% of steel workers got cancer and 40% of coal miners got cancer. Please draw a 2 by 2 table that represents this scenario. What is the AR? What is the OR? Please interpret the OR and make sure to state a time frame ) What is the CIR?With regard to cancer cells, which of the following statementsare true?A. Cancer cells are clonal, which means they are derived from asingle mutant cell.B. To become cancerous, cells usually accumulate multiplegenetic changes that eventually result in uncontrolledgrowth.C. Most cancers are caused by oncogenic viruses.D. Cancer cells have lost the ability to properly regulate celldivision.Proto-oncogenes can be converted to oncogenes in a numberof different ways. In some cases, the proto-oncogene itselfbecomes amplified up to hundreds of times in a cancer cell.An example is the cyclin D1 gene, which is amplified in somecancers. In other cases, the proto-oncogene may be mutatedin a limited number of specific ways, leading to alterations inthe gene product’s structure. The ras gene is an example of aproto-oncogene that becomes oncogenic after suffering pointmutations in specific regions of the gene. Explain why thesetwo proto-oncogenes (cyclin D1 and ras) undergo such differentalterations to convert them into oncogenes
