- illustrate some of the molecular mechanisms leading from loss-of-function mutations in tumor-suppressor genes to increased predispositions to cancer?Apart from p53, mention and describe the function of three tumor suppressor genes you knowWhy are some chromosomal regions amplified/deleted in a specific manner in certain tumor types?
- What are Tumor-suppressor genes ?Distinguish between proto-oncogenes and tumor-suppressor genes. To become cancer promoting, do proto-oncogenes and tumor-suppressor genes undergo gain-of-function or loss-of-function mutations? Classify the following genes as proto-oncogenes or tumor-suppressor genes: p53, ras, BCL-2, JUN, MDM2, and p16.Define tumor-suppressor genes. Why is a mutation in a single copy of a tumor-suppressor gene expected to behave as a recessive gene?
