7 Dyes Might Be Injected Into A Tumor For What Reasons A These Dyes Will Selectively Kill Cancer Cells But Not Normal 1 (64.25 KiB) Viewed 162 times

7. Dyes might be injected into a tumor for what reasons: a. These dyes will selectively kill cancer cells but not normal cells when injected into the tumor. b. The dye can be traced back to the draining lymph node to assess for cancer metastasis. c. As a mark to help the oncologist know which tumors have already been biopsied. 8. Why are quiescent cancer cells resistant to cancer therapies? a. They are not. Indeed, they are easier to kill because they are weak. b. They are not using many activities that cancer therapies target, such as DNA replication and proliferation, protein synthesis, glucose metabolism, kinase signaling, and others. C. They migrate away from the therapy and thereby evade killing. d. Since they are not proliferative, they have extended time to repair DNA damage that might result from genotoxic therapies (e.g., radiation therapy) before replicating it. As a result of this repair, the quiescent cell retains less DNA damage from the therapy. e. They typically express high levels of MDR (Multi-Drug Resistance) enzymes. 9. What determines where a particular cancer will metastasize to? a. Blood flow. b. Gravity. c. Lymph flow. d. Proximity - the nearest next-door tissue is at greatest risk.
