- With regard to cancer cells, which of the following statementsare true?A. Cancer cells are clonal, which means they are derived from asingle mutant cell.B. To become cancerous, cells usually accumulate multiplegenetic changes that eventually result in uncontrolledgrowth.C. Most cancers are caused by oncogenic viruses.D. Cancer cells have lost the ability to properly regulate celldivision.Some germ-line mutations predispose individuals tocancer, yet often environmental factors (chemicals,exposure to radiation) are considered major risks fordeveloping cancer. Do these views of the cause ofcancer conflict, or can they be reconciled?Part A and B A. What are the Hallmarks of Cancer? A) Criteria that are used to identify tumors in patientsB) Criteria that are used to classify cancers in patientsC) Criteria that must be met for cancer development and maintenanceD) Criteria that must be met to prevent cancer B. What is not a Hallmark of Cancer? A) Sustained proliferative signalingB) Sustained apoptosisC) ImmortalityD) AngiogenesisE) Evasion of growth suppressors
- Explain how mutations in tumor-suppressor genes can be recessive at the level of the cell but cause dominantly inherited predispositions to cancer.Discuss the complete cell cycle in a human cell, mitosis and meiosis, and the regulatory components (i.e. the proteins associated with cellular checkpoints) of the cell cycle. Tumor growth results when the cell cycle checkpoints are ignored. Give an example of how tumor growth could result from either a loss-of-function or a gain-of-function mutation.Most forms of cancer involvea. the activation of a single oncogene.b. the inactivation of a single tumor-suppressor gene.c. the activation of multiple oncogenes.d. the activation of multiple oncogenes and the inactivation ofmultiple tumor-suppressor genes.
- Apart from p53, mention and describe the function of three tumor suppressor genes you knowTissues and differentiation a)Explain what is meant by termination and differentiation ).b) Explain the difference between an oncogenic and a tumour suppressor gene and describe how they are involved in the onset of cancerIn 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.
- EXPLAIN BRIEFLY: Explain the molecular mechanisms of cancers caused by a P53 gene mutation.Explain why mutations in tumor suppressor genes are recessive (both copies of the gene must be defective for the regulation of cell division to be defective), whereas mutations in oncogenes are dominant.Which of the following types of mutations would be advantageous to a cancer cell (select all that apply)? A. An inactivating mutation in a tumor suppressor gene B. Methylation of the promoter of a tumor suppressor gene C. An inactivating mutation in an oncogene D. Mutation that inactivated DNA repair gene E. An inactivating mutation in an oncogene
