- Explain in general what is meant by a proto-oncogene and how they are involved in the formation of a tumorThe P63 and P53 have similar functionalities in the cell, however, p53 is rarely associated directly with p63, suggesting that p63 may indirectly act as an oncogene by blocking p53 function. This hypothesis may also explain why p63 is associated with other indications of misinterpretation. I do understand the above statement, however once piece not clear – why would p63 block p53 function? Have these genes been shown to have opposing functions? From the background information provided above, it seems like they would have seminar functions. Explain.Which of the following could be classified as an oncogene? None are possible oncogenes A mutant of MAP kinase that was active with or without being phosphorylated All are possible oncogenes A mutant of MEK with significantly reduced enzyme activity A mutant cAMP phosphodiesterase that made it super-active
- Which of the following mutations will result in cancer? a. homozygous recessive mutation in a tumor-suppressor gene coding for a nonfunctional protein b. dominant mutation in a tumor-suppressor gene in which the normal protein product is overexpressed c. homozygous recessive mutation in which there is a deletion in the coding region of a proto-oncogene, leaving it nonfunctional d. dominant mutation in a proto-oncogene in which the normal protein product is overexpressedWhich of the following statements about cancer is false? (a) oncogenes arise from mutations in proto-oncogenes (b) tumor suppressor genes normally interact with growth-inhibiting factors to block cell division (c) more than 120 cancer-driving genes have been discovered (d) oncogenes were first discovered in mouse models for cancer (e) the development of cancer is usually a multistep process involving both oncogenes and mutated tumor suppressor genesThe palladin gene, which plays a role in pancreatic cancer (see theintroduction to this chapter), is said to be an oncogene. Which of itscharacteristics suggest that it is an oncogene rather than a tumorsuppressorgene?
- The Human papillomavirus (HPV) has been linked to an increased risk of cervical cancer. The HPV E6 and E7 proteins govern the cell via altering cellular proteins. The E6 protein interacts with the tumor suppressor protein p53 and directs its ubiquitin-mediated destruction. Can you elaborate about the P63 gene: its function and if it can be altered/mutated by HPV? If it does, what is the relationship between P53 and P63? Thank you!All of the following are characteristics of oncogenes EXCEPT Multiple Choice they are mutated proto-oncogenes. they cause cancer. they are genes that stimulate uncontrolled cell division. they are tumor suppressor genes.All but which of the following best explains the advantage of cancer cells expressing PKM2 over PKM1? OPKM1 has lower activity PKM2 allows for accumulation of glycolytic intermediates Serine is a more potent allosteric effector of PKM2 Higher serine levels lead to increased activity of PKM2 O O
- The myc oncogene increases expression of the glutamine transporter and glutaminase that converts glutamine to glutamate. How does this contribute to increased proliferation of those cancer cells? What are the reactions and enzymes that are a part of this?The mutation of which of the following proto-oncogenes can lead to an increased susceptability to cancer, due to faulty growth factors? Multiple Choice BRCA1 p53 Ras Bax 4In tumor cells obtained from patients with Burkittlymphoma, a cancer of the immune system’s B cells,the myc gene often appears close to one of the breakpoints of a reciprocal translocation between chromosomes 8 and 14. In this translocated position, myc is expressed at a higher-than-normal level. Scientists hypothesize that Myc protein overexpression in B cellscontributes to lymphoma formation.a. Explain how transgenic mice produced using pronuclear injection could be used to test this hypothesis. (Assume that you previously cloned a generegulatory region that is active specifically in Bcells throughout the life of the mouse.)b. Suppose you wanted to overexpress Myc only inthe immune cells of mice, starting at one week ofage. To restrict Myc transcription spatially, youwill use same promoter described in part (a). Torestrict Myc transcription temporally, you will usea cre transgene whose expression is controlled byheat shock (hs-cre). Describe the mouse you wouldcreate to accomplish…
