Chapter 16, Problem 2ITD
Summary Introduction
To review:
The risk factor responsible for the death of a woman, if she carries a mutated BRCA1gene based on the given study.
Introduction:
Cancer is a disease developed due to unlimited cell division. It is a genetic disease in which changes take place in the genes due to mutations. Some mutations are hereditary and the cancer caused due to this are called familial cancers and the other cancers that are non-hereditary are known as sporadic cancers.

Describe the general process of cell signalling pathways: what events take place for a signal to cause cellular changes? Provide examples and how perturbation of these events can result in “cancer pathways”. In addition, describe in detail a typical cancer pathway and its strategy to activate gene expression. What is the origin of many cancer pathways, i.e., during which stage of an organism’s live process(es) are they physiologically activated? Why is this important for cancer development?

- 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…arrow_forwardThe MET oncogene is a growth factor receptor that is altered in many forms of cancer including lung and colon carcinomas as well as several forms of melanoma. One assay for characterizing the gene composition of tumor cells is Fluorescence in situ Hybridization (FISH) in which a fluorescently labeled DNA is used to show the presence of and level (i.e. number copies) of a gene inside cells. The experiment below is a FISH assay of two different tumor samples (Patient D and Patient E) using a MET gene probe labeled with a green fluorescent probe. The figure on the right presents the survival data from diagnosis of cancer patients with FISH data similar to Patient D or E. Based on this data, what has happened to the MET gene in Patient D population that has made their cancer more severe and reduced survival time (Limit 4-5 sentences).

However, one can predict whether a gene potentially encodes for a protein that influences carcinogenesis by examining their mutational profile. You sequence the genome of 4 cancers and identify 3 genes of interest. Which of the following genes has the best potential to an oncogene? Tumor 1 Tumor 2 Tumor 3 Tumor 4 Gene A S24F, N465T R33T T345S, G366R P367E, P368Y Gene B S34R, F360I S34R V254I S34E, T67Y Gene C S24F, I322E C255I, E344D S34E, P367Earrow_forward
- Which of the following statements are correct about cytoplasmic signaling in cancer cells? Multiple answers. A. Only minor modifications of cell control machinery are required for normal cells to become highly proliferating cancer cells B. Immediate early genes are induced in the presence of protein synthesis inhibitors C. Many immediate -early genes are oncogenes D. Delayed early genes are highly expressed in the presence of protein synthesis inhibitors E. Delayed early genes are highly expressed in normal cells in the absence of growth factorsarrow_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_forward1) Create a graph as a better way to display the data in the table 2) Determine which mutations (5q, 18q, 17p, Ras) caused the progression to each stage of tumorigenesis.arrow_forward
- Why is it important to model cancer through the generation of induced pluripotent stem cells ? Explain in detail the main findings. Please sort as a list.arrow_forwardThe best strategy for treating a specific type of human tumor can depend on identifying the type of cell that became cancerous to give rise to the tumor. For some tumors that have colonized a distant location (metastasized), identifying the parental cell type can be difficult. Because the type of IF protein expressed is cell-type-specific, using monoclonal antibodies that react with only one type of IF protein can help in this identification. What IF proteins would you produce monoclonal antibodies against to identify (a) a sarcoma of muscle cell origin, (b) an epithelial cell carcinoma, and (c) an astrocytoma (glial cell tumor)?arrow_forwardWhy is it important to model cancer through the generation of induced pluripotent stem cells ?

- Genetic tests that detect mutations in the BRCA1 and BRCA2 tumor-suppressor genes are widely available. These tests reveal a number of mutations in these genes—mutations that have been linked to familial breast cancer. Assume that a young woman in a suspected breast cancer family takes the BRCA1 and BRCA2 genetic tests and receives negative results. That is, she does not test positive for the mutant alleles of BRCA1 or BRCA2. Can she consider herself free of risk for breast cancer?arrow_forwardPlease answer question 8arrow_forwardIn what category of cancer-related genes is it possible to find inherited variants that are associated with cancer? Why? Group of answer choices 1. Tumor suppressor genes, because genes in this category are very important in the process of developing cancer. 2. Proto-oncogenes, because individuals who carry only one cancer-causing allele will have a wildtype phenotype. 3. Proto-oncogenes, because there are very few genes in this category, so mutations in them are rare. 4. Tumor suppressor genes, because individuals who carry only one cancer-causing allele will have a wildtype phenotype.arrow_forward
