Match each of the changes that can contribute to cancer with its correct description. Loss of function of regulators that send old or damaged cells into apoptosis Hyperactivation of signalling pathways that tell the cell to grow and divide 1. Sustaining proliferative signalling Loss of function of structural proteins that anchor cells to surrounding tissue and/or activation of cell migration 2. Evading growth suppressors 3. Activating invasion and metastasis Loss of function of 4. Enabling replicative immortality regulators that stop inappropriate growth and cell division 5. Inducing angiogenesis 6. Resisting cell death Loss of function of regulators that force aging cells to exit the cell cycle and enter GO or replicative senescence

The Human papillomavirus (HPV) has been linked to an increased risk of cervical cancer. The HPV E6 and E7 proteins govern the cell via altering cellular proteins. The E6 protein interacts with the tumor suppressor protein p53 and directs its ubiquitin-mediated destruction.   Can you elaborate about the P63 gene: its function and if it can be altered/mutated by HPV?  If it does, what is the relationship between P53 and P63? Thank you!

Childhood exposure to all of the following risk factors increases susceptibility to cancer except. O a. drugs. b. viruses. O c. ionizing radiation. d. cigarette smoke.

The best strategy for treating a specific type of human tumor can depend on identifying the type of cell that became cancerous to give rise to the tumor. For some tumors that have colonized a distant location (metastasized), identifying the parental cell type can be difficult. Because the type of IF protein expressed is cell-type-specific, using monoclonal antibodies that react with only one type of IF protein can help in this identification. What IF proteins would you produce monoclonal antibodies against to identify (a) a sarcoma of muscle cell origin, (b) an epithelial cell carcinoma, and (c) an astrocytoma (glial cell tumor)?
