how do tumor suppressor genes and proto-oncogenes causes cancer?
Suppose you discover a new gene called ABC that contributes to the efficiency of DNA damage repair. You have noticed that cells carrying mutations in this gene stop dividing and go into senescence. Do you think that mutations in this gene can cause cancer? Briefly explain your answer.

The vast majority of human cancers mutations in the p53 gene. What is the function of p53 normally in the cell? What happens when p53 is mutated? Is this a gain of function or loss of function mutation?
Every year, about a million Americans are diagnosed with cancer. This means that about 75 million Americans now living will eventually have cancer, And one in five will die of the disease. There are many kinds of cancers and many causes, such as smoking, overexposure to ultraviolet rays, a high fat and low fiber diet, and some workplace chemicals. Hundreds of millions of dollars are spent each year on searching for treatment, yet less money is spent on prevention. Should we devote more resources to treating cancer or to preventing it? Explain.
What is the role of regulatory gene mutations in cancer?
p53 iš an important tumor suppressor gene that is activated in response to a variety of stress signals. Upon activation it induces a cell cycle arrest or cell death. Hence, loss-of-function mutations in the p53 gene are found in almost every type of cancer. How do you predict loss-of-function mutations in the DNA binding domain of the p53 protein affect its function? OIt no longer will act as activator of gene expression O It no longer will act as repressor of gene expression O It no longer will act as activator or repressor of gene expression O It no longer will act as coactivator or corepressor
Some cancers have been treated with drugs that demethylate DNA.Explain how these drugs might work. Do you think the cancer-causinggenes that responded to the demethylation are likely to have beenoncogenes or tumor-suppressor genes? Explain your reasoning.
