- There are three broad categories of cancer-related genes: proto-oncogenes, tumor suppressor genes, and DNA stability/repair genes. Define each of these categories and indicate which one you think the RB1 gene belongs to and why.Why is it harder to develop a drug that targets a tumor suppressor gene compared to an oncogene (limit 3-4 sentences)?p53 is a gene / protein often associated with cancer. Why? What does p53 do? What kind of gene is it? Is it associated more with any one particular type of cancer or all cancers? Tell me more about p53, but please do not exceed one typed page.
- Compare and contrast oncogenes and tumor suppressors. Contrast oncogenes and proto-oncogenes. Describe the types of mutations that convert proto-oncogenes into oncogenes. Summarize some functions of common oncogenes in cell survival and uncontrolled growth. Contrast tumor suppressors to oncogenes. Describe the types of mutations in tumor suppressors that are found in common cancers. Summarize the functions of common tumor suppressors in cell survival and cell growth.There are many types of cancer. What do all types of cancer have in commonduring tumor progression, additional mutations occur within multiple cells of a tumor population, leading to multiple different clones of cells within that tumor. Some) but not all) clones may eventually metastasize, depending on the number and type of mutations that occur in those clones. true false
- To determine : The number of chromosomes in the HeLa cell. Concept introduction: HeLa cell is the oldest and commonly used cell line that was derived from the cervical cancer cells. HeLa cells differ from the normal cells in many ways. These cells have the ability to contaminate other cell lines. These cells have furthered the understanding of cancer, HIV and the cells in general. It is still used widely to grow viruses and to test anti-tumor medicines.In your own words, explain each of the hallmarks of cancer. (immortality, produce go signals, override stop signals, resist cell death, angiogenesis and how it relates to metastasis.Define the following terms: tumor, neoplasia, anaplasia, metastasis, proto-oncogene, oncogene, and tumor suppressor gene.
