Chapter 37, Problem 3DAA
Cervical Cancer Incidence In HPV-Positive Women In 2003, Michelle Khan and her coworkers published their findings on a 10-year study in which they followed cervical cancer incidence and HPV status in 20,514 women. All women who participated in the study were free of cervical cancer when the test began. Pap tests were taken at regular intervals, and the researchers used a DMA probe hybridization test (Section 15.3) to detect specific types of HPV in the women's cervical cells.
The results are shown in FIGURE 37.26 as a graph of the incidence rate of cervical cancer by HPV type. HPV- positive women are often infected by more than one type, so the data were sorted into groups based on the women's HPV status ranked by type: either positive for HPV16; or negative for HPV16 and positive for HPV18; or negative for HPV16 and HPV18 and positive for any other cancer-causing HPV; or negative for all cancer-causing HPV.
Follow-up time (months)
FIGURE 37.26 Cumulative incidence rate of cervical cancer correlated with HPV status in, 20,514 women aged 16 years and cider.
The data were grouped as follows:
● HPV16 positive
○ HFV16 negative and HPV18 positive
▼ All other cancer-causing HPV Types combined
∇ No cancer-causing HPV type was detected.
3. Is it possible to estimate from this graph the overall risk of cervical cancer that is associated with infection of cancer-causing HPV of any type?

Laura Brennan, a human papillomavirus (HPV) vaccine advocate and cervical cancer casualty, was diagnosed with HPV-16-associated
cervical cancer at age 24. In 2018, U.S. health officials extended the allowable age for the HPV vaccine to 45.
Determine which patients will have the greatest chance of protection from the Gardasil vaccine, which prevents infections of nine
strains of HPV including HPV-16 and HPV-18 and five additional types of cancer-causing HPV as well as strains HPV-6 and HPV-11 that
cause genital warts. Recall that vaccines train the body's immune system to recognize a particular infection (see figure).

- 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?

"The successful use of gene therapy to cure SCID syndrome (2000) is hoped to be a permanent cure for those patients because a good copy of the problem gene was inserted into the patients' blood stem cells in the bone marrow (hematopoietic stem cells). Once white blood cells enter the blood stream they have a limited life span, on the order of a few week to months. The blood stem cells are the cells that create more white blood cells to replace those that are lost. If the gene was only inserted into the circulating mature white blood cells, the patient would only be temporarily cured until those cells were used up or died."

- You are in the process of developing a monoclonal antibody against an Influenza virus spike protein "H7." You have isolated the B cells producing antibodies against the viral H7 protein and fused those specific B cells with a unique kind of mutant myeloma cells. The myeloma cells can't make any of the three following enzymes; dihydrofolate reductase (DHFR), thymidine kinase (TK), and hypoxanthine-guanosine phosphoribosyl transferase (HGPRT). The mutant unfused myeloma cells are grown in the laboratory in a nucleotide supplemented medium.

- Retroviruses can cause cancer, along with some viruses with DNA genomes. For example, herpes papillomavirus causes cervical cancer. The HPV genome encodes a protein called E6 that interferes with p53 function, and another protein called E7 that inhibits the function of Rb protein. Explain how HPV causes cancer. Are the viral E6 and E7 protein functions more similar to oncogenes or tumor suppressors?arrow_forwardExplain why a vaccine can prevent cervical cancer.arrow_forward Mr. Yeboah, diagnosed with a malignant tumour of the liver had it removed and was given a course of chemotherapy. Initially, tumour marker (AFP) activity activity was 7500KU/L (which is very high) but after treatment, this gradually declined to only 5KU/L. A routine follow up test was perfomedafter 3 months and the results was 15KU/L for AFP. The doctor suspected a relapse of the tumour and so referred Mr. Yeboahto an oncologist at a cancer centre who also did a re-check. AFP was recorded to be 5KU/L. Enquiries revealed that the hospital and the cancer centre use different instruments for the measurement of AFP. Both results are normal even though the values are significantly different because different methods were used.a) How can both labs confirm that the results are not clinically significant? b) How can both labs avoid this happening again?arrow_forward
