In Metastatic Breast Cancer [such as in Breast Invasive Ductal Carcinoma; Breast Invasive Carcinoma, NOS; Breast Invasive Cancer, NOS; Invasive Breast Carcinoma; Breast Invasive Lobular Carcinoma; Breast Mixed Ductal and Lobular Carcinoma] what role does the genes Tp53 and Tp63 have? Would one of them affect the other (i.e. mutation, etc) or there is not relationship among the two genes at all.

In what category of cancer-related genes is it possible to find inherited variants that are associated with cancer? Why? Group of answer choices 1. Tumor suppressor genes, because genes in this category are very important in the process of developing cancer. 2. Proto-oncogenes, because individuals who carry only one cancer-causing allele will have a wildtype phenotype. 3. Proto-oncogenes, because there are very few genes in this category, so mutations in them are rare. 4. Tumor suppressor genes, because individuals who carry only one cancer-causing allele will have a wildtype phenotype.
Distinguish between proto-oncogenes and tumor-suppressor genes. To become cancer promoting, do proto-oncogenes and tumor-suppressor genes undergo gain-of-function or loss-of-function mutations? Classify the following genes as proto-oncogenes or tumor-suppressor genes: p53, ras, BCL-2, JUN, MDM2, and p16.
Genetic tests that detect mutations in the BRCA1 and BRCA2 oncogenes are widely available. These tests reveal a number of mutations in these genes—mutations that have been linked to familial breast cancer. Assume that a young woman in a suspected breast cancer family takes the BRCA1 and BRCA2 genetic tests and receives negative results. That is, she does not test positive for the mutant alleles of BRCA1 or BRCA2. Can she consider herself free of risk for breast cancer?
"Changes to the p53 protein structure can be caused by differences in DNA and can affect protein function." Can you give detailed explanation why this is causation and not correlation? The explanation should be related with mutation, structure changes during protein synthesis, chemical property changes in amino acids, and functions of p53 protein.
What significance do BRCA1 and BRCA2 have in regard to developing cancer, and what types of cancer are associated with these genes?
"In most differentiated tissues, daughter cells retain a memory of gene expression patterns that were present in the parent cell through mechanisms that do not involve changes in the sequence of their genomic DNA" is true or false.

Which of the following mutations will result in cancer? a. homozygous recessive mutation in a tumor-suppressor gene coding for a nonfunctional protein b. dominant mutation in a tumor-suppressor gene in which the normal protein product is overexpressed c. homozygous recessive mutation in which there is a deletion in the coding region of a proto-oncogene, leaving it nonfunctional d. dominant mutation in a proto-oncogene in which the normal protein product is overexpressed
The gene controlling ABO blood type and the gene underlying nail-patella syndrome are said to show linkage. What does that mean in terms of their relative locations in the genome? What does it mean in terms of how the two traits are inherited with respect to each other?
Which of the following effectively describes the situation of someone with an inherited predisposition to cancer such as familial adenomatous polyposis or BRCA-associated familial breast cancer? Choose all that apply a) If they get malignant cancer, somatic mutations will not have been a factor b) Their cancer will most likely arise in their germ cells, not their somatic cells c) None of the answers effectively describes the situation d) Every cell of their body contains a gain-of-function allele of an oncogene e) Most cells in their body contain multiple cancer-causing mutations f) Every cell of their body contains a defective, loss-of-function allele of a tumor suppressor gene
Classify the following genes as proto-oncogenes or tumor-suppressor genes: p53, ras, Bcl-2, telomerase, jun, and
The P63 and P53 have similar functionalities in the cell, however, p53 is rarely associated directly with p63, suggesting that p63 may indirectly act as an oncogene by blocking p53 function. This hypothesis may also explain why p63 is associated with other indications of misinterpretation. I do understand the above statement, however once piece not clear – why would p63 block p53 function? Have these genes been shown to have opposing functions? From the background information provided above, it seems like they would have seminar functions. Explain.
