Question
Chapter 18, Problem 7A
Summary Introduction
Introduction:
The comparative proteomics study involves comparison between proteomes (entire proteins that can be expressed by cells) from different tissues or cells from different sets of conditions. The main goal of this is to analyze changes in proteome in response to disease, development or environment.

Which disease or medical problem did Wassif et al. want to tackle with this mouse knockout? (If you cannot remember you may describe it.) B.) How did the phenotype of their mouse model differ from those of patients who had mutations in DHCR7 gene? And how was it similar? C.) What is one reason to explain the differences between the DHCR7 mouse knockout model and human patients with the mutations in the DHCR7 gene OTHER THAN the fact that they are two different organisms with differences in their biology? D.) With your BIOL2299 expertise, assume you generate a mouse knockout model of a human disease. Imagine one real world outcome from your study which can be applied in a clinical setting to help patients with that disease.

The swo-1 a mutation (insertion between C and G). 4. The swo-1 b mutation (C-to-T mutation for indicated C). 5.

- Design a strategy to make a subtracted-complete cDNA library from liver cells. Use a flowchart method to propose how this objective can be accomplished. The sizes of mRNA range from 2 kb to 15 kb. Briefly indicate your reasons for the sequence of steps..arrow_forwardCould quantitative PCR, which uses a DNA-binding dye, to show how many copies of the target DNA sequence could be used to quantify the amount of mRNA in a cell? Would you expect that a metabolically active tissue such as the liver would show more cDNA copies in such a method, compared to less metabolically active tissues such as skin cells? One reason that the types and amounts of mRNAs are quantified in different tissue types is to compare which genes are activated and which are inactive. It used to be thought that any gene that was transcribed was automatically translated. The discovery of RNA-degrading systems shows that the real situation in cells is more complemented. Do you believe that a larger amount of mRNA of a given type, say for alpha hemoglobin in immature red blood cells is a reliable indicator that more alpha hemoglobin protein will be made in those cells?arrow_forwardGiven: eukaryotic cells can make different proteins, using only one gene. How can a eukaryotic cell make different final proteins from the same gene? Note: some of the answers are actually correct statements, but they don't have anything to do with this question. A.Eukaryotes have 3 RNA polymerases instead of just one. B.Eukaryotes cannot perform simultaneous transcription and translation. C.Eukaryotes splice RNA and can do so in various arrangements. D.Eukaryotes lack the Shine Delgarno sequence.arrow_forward
- Telomerase is an attractive cancer target since 85% - 90% of tumors express telomerase (while normal cells express little to no telomerase). One paradigm in this model is the “cancer stem cell” hypothesis. Cancer stem cells (or tumor-initiating cells with stem-cell like properties) can self-renew, as well as give rise to heterogeneous tumor cell populations (essentially, they are believed to be responsible for the formation and maintenance of the tumor). If these cells are indeed “stem-like” they also divide more slowly, and presumably express telomerase (like normal stem cells).Do you think a treatment strategy that inhibits telomerase would be effective in treating cancer? How does the cancer stem cell hypothesis complicate or compliment these strategies? Justify your answer.arrow_forwardSeveral research studies are under way that involve the use of genetherapies to inhibit the growth of cancer cells. Oncogenes are mutant genes that are overexpressed and cause cancer. New gene therapies are aimed at silencing oncogenes by producing antisense RNA that recognizes the mRNAtranscribed from oncogenes. Based on your understanding of antisense RNA , explain how this strategy would prevent the growth of cancer cells.arrow_forwardCancer cells removed from a patient's tumor have increased gene expression of several hundred genes (including many cancer-causing genes). Scientists determine that the histones from the cancer cells have an overall/average lower affinity for DNA than histones from normal control cells. Which drug is most likely to help treat this patient's cancer? a. An inhibitor for HMT (histone methyltransferases) b. An inhibitor for HDM (histone demethylases) c. An inhibitor for HDACs (histone deacetylases) d. An inhibitor for HATs (histone acetyltransferase)arrow_forward
