Of the following choices a loss of function mutation would most lukely contribute to cancer onset if the mutant gene codes for a :   telomerase   tumor suppressor protein   ATP synthesis enzyme    RNS binding protein

A 42-year-old woman comes to the physician for a follow-up examination after two separate Pap smears have shown dysplastic epithelial cells. Results of a molecular diagnostic test show DNA that encodes high-risk versions of the human papillomavirus E6 and E7 proteins. The viral E6 protein binds to the cellular p53 tumor suppressor gene, causing it to be degraded. Which of the following best describes the mechanism by which the E6 protein causes cervical cancer? (A) Arrests the cell cycle (B) Enhances tissue invasion and metastasis (C) Inhibits telomerase expression (D) Prevents apoptosis (E) Sustains angiogenesis

The deregulation of several signal transduction pathways is integral to the onset of cancer. These pathways involve both tumor promoters (the "gas pedals") and tumor suppressors (the "brake pedals"). Which would be a more effective treatment for cancer: A small molecule inhibitor that targets a tumor suppressor or one that targets a tumor promoter? Briefly explain your choice.
