Following exposure to an initiating agent (e.g., DMBA) a tumor promoting agent (or tumor promoter) (e.g., TPA) induces these exposed cells to undergo vigorous cell proliferation. Which statement is true about a "tumor promoter"? can causer cancer on its own enhances tumorigenesis through nongenetic mechanisms both?

Which of the following statements about cancer is false? (a) oncogenes arise from mutations in proto-oncogenes (b) tumor suppressor genes normally interact with growth inhibiting factors to block cell division (c) more than 120 cancer-driving genes have been discovered (d) oncogenes were first discovered in mouse models for cancer (e) the development of cancer is usually a multistep process involving both oncogenes and mutated tumor suppressor genes
Necrotic cells can be tumor promoting because: (select all answers that apply) A. they can release anti-inflammatory signaling molecules B. they express a gain-of-mutation in beclin-1 C. they release interleukins which then promote proliferation D. they recruit pro-inflammatory immune cells which then promote angiogenesis E. they release TGFbeta

Which of the following explains how DNA tumor viruses may cause human cancers? A. viral proteins infect other uninfected host cells B. viral proteins block the effect of tumor-suppressor genes which prevent uncontrolled cell division C. viral proteins turn off cell division D. viruses use reverse transcriptase to integrate the DNA tumor viruses into the host chromosome
