Knock-out mouse phase is very common in the experimental research in this type of mouse the specific target gene is removed for that reason it helps the researchers to understand how the gene has effect on the mice or the function of the gene.
If the mouse is SERCA2a knock-out which means the mouse genome or DNA does not contain the gene which codes for SERCA2a protein. So that the SERCA2a concentration will be low or may be possible that the mouse does not express that protein as the responsible gene is missing.
You are looking at protein levels in a SERCA2a knock-out mouse. What would you expect to...
A “knock-out” of the cyclin-cdk inhibitor p19 was generated in mice. What this means is that the gene for p19 was functionally removed. As such, the mouse was p19-/- or genetically negative for p19 and none of its cells have the p19 protein being made. They also removed the cdk4 (cyclin dependent kinase-4) in some of the mice. On a tissue level, tumors were formed in the pituitary anterior lobe, and other tissues. What would you expect to happen to...
what effect on total protein concentration would you expect to see during dehydration? explain your reasoning.
6a) You want to use homologous recombination to generate a mouse that does not express a functional XPC gene (‘Knock-out’ or KO). To do this, you want to delete exon 10 and replace it with a gene that confers resistance to the drug Neomycin (NEO. The usual second selection with tk we discussed in class is not shown here). Using the diagram as a guide: illustrate on the diagram where you expect crossing over to occur and (below the diagram)...
What is the relationship between protein translation and gene expression? Would you expect to always see correlation between these two? Discuss a circumstance within the context of cancer where mRNA and protein expression may not correlate. Why is it important to look at both protein and RNA levels of a series of genes/proteins in a molecular pathway? Discuss this in the context of cancer associated pathways. Give a specific example of a pathway that is independent of gene expression in...
4. p53 is an important cancer suppressor gene. To study its function, it is very useful to have p53 knock-out mice. How can one best prepare a strain of p53 knock-out mice? Please start with the optimal method to introduce mutations into DNA, and then describe how you would incorporate such DNA into the mouse genome. List all major steps. please give detailed answer, thank you!
3.) a) What would you expect with regards to fasting glucose levels in a patient that had a pancreatic tumor characterized by rapid proliferation and uncontrolled growth of b-cells? b) How about a pancreatic tumor characterized by rapid proliferation and uncontrolled growth of a-cells? 4.) If a glucose tolerance test were performed on an animal that had been treated several days before with alloxan, what results would you expect? Why? 5.) Insulin is generally administered via either intramuscular or subcutaneous...
If the mutation is in isocitrate dehydrogenase, what would you expect to happen to the levels of : (increase/decrease) isocitrate a- ketoglutarate glyoxylate
B. You would like to test the hypothesis that your molecule can signal through bitter taste receptors using a genetic experiment. Because there are so many different bitter taste receptors, it would not be possible to knock all of them out. However, you do have access to the PLCbeta2 knockout mouse. Describe how you can construct a mouse that retains sweet taste but lacks bitter taste reception. If your hypothesis is correct, what results do you expect in the lick...
Would you expect to see an increase or decrease in total protein concentration in haemorrhage? Explain your reasoning PLEASE answer the question with YOUR OWN WORDS if you are going to copy it from somewhere els, don't answer it please
What would you expect to happen to a newly synthesized soluble protein if a mutation caused the deletion of the KDEL sequence? a. The protein would be returned to the ER in COPI-coated vesicles. b. The protein will be carried forward through the Golgi apparatus. c. The protein will be trapped in COPII vesicles . d. The protein will be incorporated into COPI vesicles. e. The protein will be recognized by KDEL receptors and a retrieval sequence (KDEL sequence) will...
