The Bcl-2 protein was initially discovered via its ability to contribute to progression of B-cells to a cancerous "lymphoma" phenotype.
1) Define the mutation that was associated with the change in Bcl-2 in these cells.
2) Is Bcl-2 an oncogene or a tumor suppressor gene?
3) Define the role of Bcl-2 in normal cellular function and how this changed in Bcl-2 associated lymphoma.
Describe the mutational event that produces the MYC oncogene in Burkitt’s lymphoma. Why does the particular mechanism for generating oncogenic MYC result in a lymphoma rather than another type of cancer? Describe another mechanism for generating oncogenic MYC.
D)
The level of carbon dioxide increases with the level of available oxygen.

The TPS3 gene provides instructions for making a protein called tumor protein p53. Known as the guardlan of the genome,
this protein acts as a tumor suppressor, which means that it regulates cell division by keeping cells from growing and dividing
t0o fast or in an uncontrolled way. The p53 protein is located in the nucleus of cells throughout the body, where it attaches
directly to DNA and plays a critical role in determining whether the DNA will be repaired or the damaged cell will self-
destruct (undergo apoptosis). If the DNA can be repaired, p53 activates other genes to fix the damage. If the DNA cannot be
repaired, this protein prevents the cell from dividing and signals it to undergo apoptosis.
Suppose chromosomes in a skin cell are damaged by ultraviolet radiation. If the damaged genes do not affect p53, which choice
correctly predict if the cell will become cancerous and why?
No, the cell will not…

- Some cancers are consistently associated with the deletion of a particularpart of a chromosome. Does the deleted region contain an oncogene or atumor-suppressor gene? Explain.arrow_forwardAlthough slow acting retroviruses lack oncogenes, retroviral infection can activate proto oncogenes leading to oncogenesis. a. Describe the mechanism of proto-oncogenes activation that can result from with infection with slow acting retroviruses. b. In what other ways can proto-oncogenes be converted to oncogenes?arrow_forwardIn addition, when ARF is artificially expressed in normal cells, a rapid increase in p53 levels is observed. Studies have demonstrated that ARF, when expressed, is associated with Mdm2. When associated, the two proteins display a particular pattern of localization restricted to the nucleolus. Suggest a mechanism by which ARF leads to p53 build-up.arrow_forward

No, the cell will…arrow_forwardThe p53 gene is a tumor-suppressor gene while Ras is a proto-oncogene. Mutation in either one can result in the transformation of a normal cell into a cancer cell. Explain the difference between the functions of the two proteins and how their mutation can lead to cancer development.arrow_forwardCellular levels of tumor suppressor protein p53 is maintained by a ubiquitin ligase protein, called Mdm2. Over expression of Mdm2 destabilizes p53. Another protein p19ARF inhibits the activity of Mdm2, thus stabilizing p53. Loss of p19ARF function converts normal cells into cancer cells With the above information, which of the following statements are true? Mdm2 is a tumor suppressor gene but p19ARF is an oncogene Both Mdm2 & P19ARF are oncogenes Both Mdm2 & P19ARF are tumor suppressor genes O Mdm2 is an oncogene but p19ARF is a tumor suppressor genearrow_forward
- The p53 protein was discovered through its association with SV40 T antigen and assumed initially to be an oncoprotein. a. What is the current consensus as the function of p53 and what evidence caused this change in view? b. How does the effect of mutation in the p53 gene differ from the effect of mutation in the RB gene what is the molecular basis for this difference ?arrow_forwardYou are analyzing the activity of the protein p53 in two different cell types. You notice that p53 has the same primary structure in both cells, but has a different function in each cell. What could be the reason for the functional difference in this case? A. p53 mRNA has been spliced differently in each cell type. B. p53 is phosphorylated on some amino acid residues in its transactivation domain in one cell type but not in the other cell type. C. The tetramerization domain of p53 is acetylated at the same amino acid residues in both cell types. D. All of the above E. B and C onlyarrow_forwardWhat is cell differentiation?

- Mutations in the RB gene are often associated with cancer. Explain how a mutation that results in a nonfunctional RB protein contributes to cancer.arrow_forwardIn rare instances, B cells can be found that have two immunoglobulin light chain alleles, both of which are rearranged in frame, and can encode functional light chain proteins. Yet, on the surface of the B cell, only one of the two light chain proteins is detected in the membrane-bound immunoglobulin receptor. The reason these rare cells have two functional light chain rearrangements but only express one of the two light chains as part of the B-cell receptor is: One of the two light chains is formed from rearrangement of a V gene segment that is a pseudogene. One of the two light chain proteins doesn’t form a stable complex with the heavy chain expressed in this cell. One of the two light chain alleles is not transcribed efficiently, and produces only low levels of protein. One of the two light chain alleles uses a V gene segment that is not targeted very often by the RAG recombinase. One of the two light chains is rapidly degraded after synthesis due to improper folding.arrow_forwardRelatively few inherited forms of cancer involve the inheritance of mutant oncogenes. Instead, most inherited forms of cancer are defects in tumor-suppressor genes. Give two or more reasons why inherited forms of cancer seldom involve activated oncogenes.arrow_forward
