Summary Introduction
To review:
The reason for the apparent anomaly of the cancer cells to constitute both the hypomethylated and hypermethylated DNA (deoxyribonucleic acid) in the same cell.
Introduction:
Cancer epigenetics is a study of the epigenetic remodeling of the cancer cells. Epigenetics is the study of factors that contribute to the gene expression but do not modify the

- Why is it important to model cancer through the generation of induced pluripotent stem cells ? Please list item by item. Explain in detail the main findings.arrow_forwardDescribe how mutations in genome maintenance factors promote tumorigenesis. Why would inactivation of a mis- match repair gene cause colon cancer?arrow_forwardBecause the degree of DNA methylation appears to be a relatively reliable genetic marker for some forms of cancer, researchers have explored the possibility of altering DNA methylation as a form of cancer therapy. Initial studies indicate that while hypomethylation suppresses the formation of some tumors, other tumors thrive. Why would one expect different cancers to respond differently to either hypomethylation or hypermethylation therapies?arrow_forward
- Describe the differences between point mutations, chromosomal translocations, and gene amplification in the process of cancer.arrow_forwardDescribe 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?arrow_forwardPatients with XP suffer extremely high incidence of skin cancer but have not been found to have correspondingly high incidences of cancer of internal organs (e.g. colon cancer). What might this suggest about the kinds of DNA damage responsible for most internal cancers?arrow_forward
