Question
Chapter 16, Problem 1ITD
Summary Introduction
To review:
The risk related to mortality caused by cancer, based on a study on 442 women diagnosed with breast cancer, when two of their close relatives have breast cancer.
Introduction:
Cancer can be a genetic disease. It is developed by unlimited cell division, causing abnormal growth of cells. The abnormal cells are called tumor cells. Cancer is caused by certain mutations in cell, which alter the genes and with time, successively convert normal cells to cancer cells.

Describe error prone polymerases and the process of translesion synthesis (TLS). In regards to tumor biology, what is the mutator phenotype hypothesis? What are some ways in which error-prone polymerases could be targeted for potential anti-cancer treatments?

In Demircioglu et al (2019), the authors found that promoter switching for the ERBB2 gene was
often associated with mutations in other known oncogenes and tumor suppresor genes. However,
they argued that promoter switching may be correlated with cancer development and progression
regardless of additional mutations. What evidence did they have to support this idea ?
O They found that patients who had ERBB2 promoter switching but no other mutations in known oncogenes
(OG) and tumor suppressor genes (TSG) carried many other mutations in genes that may have contributed to
cancer progression and had not been identified as OG or TSG yet.
O They saw that patients that showed promoter switching but did not have any other identifiable mutations had
poorer prognosis than patients without promoter switching
This was actually a discussion point; the authors did not have any experimental evidence to support their
claim.
O They treated all patients that showed promoter switching with the same drug…

- Cellular 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_forwardWhy is it important to model cancer through the generation of induced pluripotent stem cells ?

- Cancer often results from a multistage process involving an initiating event (mediated by a viral infection or a carcinogenic chemical), followed by exposure to tumor promoters. Tumor promoters, a group of molecules that stimulate cell proliferation, cannot induce tumor formation by themselves. The phorbol esters, found in croton oil (obtained from the seeds of the croton plant, Croton tiglium), are potent tumor promoters. (Other examples of tumor promoters include asbestos and several components of tobacco smoke.) In one of the tumor-promoting actions of the phorbol esters, these molecules mimic the actions of DAG. In contrast to DAG, the phorbol esters are not easily disposed of. Explain the possible biochemical consequences of phorbol esters in an “initiated” cell. What enzyme is activated by both DAG and phorbol esters?arrow_forwardWhy is it important to model cancer through the generation of induced pluripotent stem cells ? Please explain in detailsarrow_forwardCancer can be defined as an abnormal proliferation of cells that defy the normal regulatory controls observed by normal cells. Recently, histone deacetylation therapies have been attempted in the treatment of certain cancers [reviewed by Delcuve et al. (2009)]. Specifically, the FDA has approved histone deacetylation (HDAC) inhibitors for the treatment of cutaneous T-cell lymphoma. Explain why histone acetylation might be associated with cancer and what the rationale is for the use of HDAC inhibitors in the treatment of certain forms of cancer.arrow_forward
- Personalized cancer treatments involve identifying specific pathways in an individual tumor and selecting drugs that are effective for the modified pathways. One way to do this is to take culture cells from a biopsy of a specific paient and test the effects of a battery of drugs on the patiets cells in culture. How might heterotypic interactions complicate this strategy? How might cells be cultured differently to minimize these complications (limit 5-6 sentences)?arrow_forwardIn the experiment below, mice were treated with a virus that inhibited expression of angiopoietin 2, MMP3 and MMP10 in the lung or with a control virus (Mock). Breast cancer cells that express the gene luciferase were then injected into the mammary glands of the mice. The metstasis of the tumors to the lungs could then be measured by imaging the presence of luciferase in the lungs. In 5-6 sentences, explain the data below and why knockout of Angpt2, MMP3 and MMP10 appears to inhibit metstastasis.arrow_forwardWe have studied Ras signal transduction pathway.
