Retinoblastoma is a rare cancer in which tumors developin the retina of the eye. The tumors arise because of theloss of the Rb gene, which codes for a tumor suppressor.Hereditary retinoblastoma usually appears in children whohave inherited only one functional copy of Rb. Explain whythe nonhereditary form of retinoblastoma usually occurs laterin life.

A genetic predisposition to developing cancer is usually inheritedas a dominant trait. At the level of cellular function, are the allelesinvolved actually dominant? Explain why some individuals whohave inherited these dominant alleles do not develop cancer duringtheir lifetimes.
Some cancers show increased incidence with age while others peak at younger ages. Whydo you suppose that some cancers have increased incidence with age while others peak inchildren?
When the DNA of a human cell becomes damaged, the p53 geneis activated. What is the general function of the p53 protein?Is it an enzyme, transcription factor, cell-cycle protein, orsomething else? Describe three ways in which the synthesisof the p53 protein affects cellular function. Why is it beneficialfor these three things to happen when a cell’s DNA hasbeen damaged?
Marfan syndrome is due to a mutation in a gene that encodes aprotein called fibrillin-1. It is inherited as a dominant trait. Thefibrillin-1 protein is the main constituent of extracellular microfibrils.These microfibrils can exist as individual fibers or associatewith a protein called elastin to form elastic fibers. People with thedisorder tend to be unusually tall with long limbs, and they mayhave defects in their heart valves and aorta. Let’s suppose aphenotypically unaffected woman has a child with a man whohas Marfan syndrome.A. What is the probability this child will have the disease?B. If this couple has three children, what is the probability thatnone of them will have Marfan syndrome?
Glioblastoma multiforme (GBM) is the most commonand aggressive form of brain cancer in humans.Without any treatment, the mean survival rate is aboutthree months. Even with standard treatments such assurgical resection, radiation, and chemotherapy, themean survival rate is between seven and 14 months.GBM tumors differ in their spectrum of geneticchanges, and these changes may influence the effectof particular treatments. Answer the following questions about the relevance of particular mutations toparticular treatments and outcomes.a. Biopsies of about 20% of GBMs show the expression of a certain mutational variant of the EGFR(epidermal growth factor receptor) protein calledEGFRvIII. The same cancerous cells of theseGBMs also show the expression of normal, wildtype EGFR. Is the gene encoding EGFR a tumorsuppressor gene or a proto-oncogene?b. It is very difficult to induce cells expressingEGFRvIII to undergo apoptosis. If you werea radiologist treating a patient with a GBMthat expresses…
Explain what it means when cancer is said to have a hereditary component.
You have treated undifferentiated embryonic stem cells (ESCs) with sonic hedgehog (Shh)for several days. This should induce a neural fate in your ESCs and you hope that you havebeen successful in differentiating the ESCs into NSCs. What is one assay you could use to testwhether your cells had differentiated into NSC-like cells? Name and shortly describe the assay?
One major goal of modern cancer therapy is toidentify small molecules—anticancer drugs—that canbe used to inhibit the products of specific cancer-criticalgenes. If you were searching for such molecules, wouldyou design inhibitors for the products of oncogenes orthe products of tumor suppressor genes? Explain why youwould (or would not) select each type of gene.

In Model 1, if the length of the arrow represents time, then for those cancerous cells, what hap pens to the time that is necessary for the cell cycle? What implication might this have for doctors who are treating cancer patients? Why? Living things must grow and develop. At times they suffer injuries or damage, or cells simply wear out. New cells must be formed for the organism to survive. What process must occur to make a new, properly- functioning cell?

Explain why mutations in tumor suppressor genes are recessive (both copies of the gene must be defective for the regulation of cell division to be defective), whereas mutations in oncogenes are dominant.
Proto-oncogenes can be converted to oncogenes in a numberof different ways. In some cases, the proto-oncogene itselfbecomes amplified up to hundreds of times in a cancer cell.An example is the cyclin D1 gene, which is amplified in somecancers. In other cases, the proto-oncogene may be mutatedin a limited number of specific ways, leading to alterations inthe gene product’s structure. The ras gene is an example of aproto-oncogene that becomes oncogenic after suffering pointmutations in specific regions of the gene. Explain why thesetwo proto-oncogenes (cyclin D1 and ras) undergo such differentalterations to convert them into oncogenes
