Pancreatic cancer is clearly inherited as an autosomal dominant trait in the family illustrated in Figure 23.1. Yet most cases of pancreatic cancer are sporadic, appearing as isolated cases in families with no obvious inheritance. How can a trait be strongly inherited in one family and not inherited in another?
Cancer is an uncontrolled division of cell that has a defunct apoptosis mechanism. Usually, when cells come in close proximity to each other, they tend to get destroyed. This is a property of cell called as contact inhibition. But cancerous cells lack this property and hence they accumulate together and continue to divide in an uncontrolled manner thereby leading to tumors.

Thanks!Skin cancer carries a lifetime risk nearly equal to that of allother cancers combined. Following is a graph [modified fromK. H. Kraemer (1997). Proc. Natl. Acad. Sci. (USA) 94:11–14]depicting the age of onset of skin cancers in patients with orwithout XP, where the cumulative percentage of skin cancer is plotted against age. The non-XP curve is based on 29,757 cancerssurveyed by the National Cancer Institute, and the curverepresenting those with XP is based on 63 skin cancers from theXeroderma Pigmentosum Registry.

Would one of them affect the other (i.e. mutation, etc) or there is not relationship among the two genes at all.how do i expand this into 1000 words for a result section of a report The objective is to interpret the results of an RNA-Seq analysis to identify differentially expressed genes in breast cancer using figure 1. The data provided includes gene symbols, chromosome location, start and end points, strand, fold change, log2 fold change, p-value, and false discovery rate (FDR). The RNA-Seq analysis has identified several genes that are differentially expressed in breast cancer. These genes are located on various chromosomes and have varying levels of fold change, indicating the degree to which their expression levels differ between normal and cancerous cells. The gene with the highest fold change is EYA4, located on chromosome 6, with a fold change of 3604.4176. This indicates that the expression of this gene is over 3600 times higher in cancer cells compared to normal cells. The log2 fold change is 11.81555, which is a measure of the magnitude of the difference in gene expression. The…
- Describe the mutational event that produces the MYC oncogene in Burkitt’s lymphoma. Why does the particular mechanism for generating oncogenic MYC result in a lymphoma rather than another type of cancer? Describe another mechanism for generating oncogenic MYC.Question 1. Describe and explain the epidemiological evidence supporting the view that cancer develops through a multi-step process involving increasingly severe stages.. Question 2. Describe and explain the genetic evidence supporting the view that cancer develops through a multi-step process involving increasingly severe stages.Cancer-promoting mutations are likely to have different effects on the activity of proteins encoded byproto-oncogenes than they do on proteins encodedby tumor-suppressor genes. Explain.
- Under normal physiological conditions, proto-oncogenes and tumor suppressorshelp control cell growth and proliferation. When mutated, these proteinscontribute to the development of cancer. Briefly detail the molecular basis of thisphenomenonThe development of colon cancer is particularly well- studied, and often has a predictable order of mutations. Briefly describe the most common steps in the progression of colon cancer in the order of key genes mutated.Out of these 8 hallmarks ( sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, activating invasion and metastasis, deregulating cellular energetics and metabolism, and avoiding immune destruction). Rank them from least important to most for cancer development. Explain in 2-3 sentences how.
