Textbook Question
Chapter 16, Problem 2PDQ
Review the Chapter Concepts list on page 307. These concepts relate to the multiple ways in which genetic alterations lead to the development of cancers. The sixth concept states that DNA methylation and histone modifications contribute to the genetic alterations leading to cancer. Write a short essay describing how these changes in cancer cells contribute to the development of cancers.

Explain in detail the main findings. Please sort as a list.
Tumor suppressor genes and oncogenes are implicated in carcinogenesis. 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?

examine the process of gene expression. Include the following: Explain the regulation of gene expression in eukaryotic cells. Discuss mechanisms by which gene expression may be altered. How do these alterations induce cancer-causing mutations in cell DNA? Explain how cancer is formed. Describe genetic changes found in cancer cells and how these changes lead to alterations in cell behavior. Determine whether proteome data can be utilized in genetic disorder diagnosis. Relate the Human Genome Project data to the analysis of cancer genes. Relates the Human Genome Project's utility in pharmacogenomics and personalized medicine to diagnose and treat cancer

- Describe the differences between point mutations, chromosomal translocations, and gene amplification in the process of cancer.arrow_forwardOn the image, you can see the results of a DNA microarray used for cancer prognosis, where tissue samples from healthy and cancerous tissues were analyzed. cDNA from healthy cells and cancer cells were labeled with green and red fluorescence, respectively, mixed equally, and hybridized with the chip. It is known that gene A is more highly expressed in breast cancer type I, while genes B and C have lower expression in type II, which is highly aggressive. Based on the gene expression levels shown in the image, the cancer sample does not correspond to either type I or type II breast cancer, why is that?arrow_forwardGenetic 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_forward
- Why is it important to model cancer through the generation of induced pluripotent stem cells ? Explain in detail the main findings.arrow_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_forwardResearchers have identified some tumors that have no recurrent mutations or deletions in known oncogenes or tumor-suppressor genes and no detectable epigenetic alterations. However, these tumors often have large chromosomal deletions. What are some possible explanations that could account for the genetic causes behind these tumors?arrow_forward
