Textbook Question
Chapter 21, Problem 11PIAT
Will iPS cells be the cure for diabetes?
Type I diabetes is a form of diabetes that is due to the loss of insulin- producing cells of the pancreas. The potential of stem cells–in particular, induced pluripotent stem (iPS) cells–for therapy has gotten a lot of press. Can iPS cells be coaxed to differentiate into insulin-producing cells? Is there any evidence that they might actually work to cure type I diabetes?
What are iPS cells?
a. cells taken from early human embryos
b. cells taken from the pancreas of people without diabetes
c. cells derived by de-differentiating specialized adult cells
d. cells derived by differentiating pancreas precursor cells

Discuss the principles that govern the presence and maintenance of stem cells both in vivo and in vitro?
What is the current status of the technology, and its possible applications?
What are the pros and cons of the technology, and how do these issues personally affect people?
Why is it easier to manipulate embryonic stem cells to differentiate into various tissues than it is to manipulate a typical adult cell?
a.
As cells develop, signaling pathways can cause some genes to be turned off during development.
b.
Adult cells have different DNA content than do embryonic stem cells.
c.
Emybronic stem cells pose less of a threat for organ rejection as do an individual s own adult cells.
d.
It is no easier to manipulate emybronic stem cells to differentiate into various tissues than it is to manipulate a typical adult cell.

- 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 overexpressedarrow_forwardTGF-β1 is a protein that affects cell growth and differentiation. Scientists conducted an experiment where epithelial cells were treated with transforming growth factor beta 1 (TGF-β1) in the laboratory. At the end of the experiment, the epithelial cells had transformed through several stages from epithelial cells to embryonic stem cells (ESCs) to neural progenitor cells (NPCs), and finally to cortical neurons (CNs). The scientists observed the transformation of the cells by analyzing gene expression at certain stages (M1-M7) and determined the relative gene expression level, as shown in the graph. The graph shows the relative gene expression level for cells at different stages of differentiation. Which of the following claims could account for the differences in gene expression at each stage of cell differentiation, and how does this correlate with the distance of the genes on the chromosome? A - Cell differentiation is controlled by RNA translation, but there is no…arrow_forwardThe rb gene encodes a protein that inhibits E2F, a transcriptionfactor that activates several genes involved in cell division.Mutations in rb are associated with certain forms of cancer,such as retinoblastoma. Under each of the following conditions,would you expect the cancer to occur?A. One copy of rb is defective; both copies of E2F are functional.B. Both copies of rb are defective; both copies of E2F arefunctional.C. Both copies of rb are defective; one copy of E2F is defective.D. Both copies of rb and E2F are defective.arrow_forward
- Which of the following statements are correct about cytoplasmic signaling in cancer cells? Multiple answers. A. Only minor modifications of cell control machinery are required for normal cells to become highly proliferating cancer cells B. Immediate early genes are induced in the presence of protein synthesis inhibitors C. Many immediate -early genes are oncogenes D. Delayed early genes are highly expressed in the presence of protein synthesis inhibitors E. Delayed early genes are highly expressed in normal cells in the absence of growth factorsarrow_forwardRas is a proto-oncogene that is within the EGF pathway. The EGF receptor can activate the cell division pathway only when the EGF ligand binds to the receptor. A gain of function mutation occurs in only one copy of the Ras gene. What are all the possible consequences of this? Select all that apply. Group of answer choices The cell will undergo constant cell division The cell will still be normal as only one copy of Ras is mutated. Both copies must be mutated for the cell to undergo constant cell division There will be an increase of EGF ligands present in the cell The EGF receptor will always be active even with no EGF ligands bound and activate the pathway Ras will always be active and activate the proteins downstream that will turn on cell division Ras will be under the influence of the EGF receptor and will only activate if the EGF ligand is bound to the receptorarrow_forwardThe myc oncogene increases expression of the glutamine transporter and glutaminase that converts glutamine to glutamate. How does this contribute to increased proliferation of those cancer cells? What are the reactions and enzymes that are a part of this?arrow_forward
- Why does a single mutation in a proto-oncogene, turning it into an oncogene potentially lead to a cancerous phenotype, while it takes two mutations in tumor suppressor genes to lead to a cancerous phenotype?arrow_forwardThe p53 gene was discovered in 1979, but it was not clear whether the gene functioned as an oncogene or a tumor-suppressor gene. Several years later, researchers showed that both p53 alleles are inactivated in some mouse cancers. This evidence suggests A. the p53 gene is an oncogene because inactivated alleles would produce mutated signal transduction proteins that would result in stimulating cell division. B. the p53 gene is an oncogene because the cell would overproduce transcription factors to compensate for the inactive alleles, resulting in increased cell division. C. the p53 gene is a tumor-suppressor gene because inactivated alleles indicate a loss of protein function which allowed the cancer to develop D. the p53 gene is a tumor-suppressor gene because the cell would produce too few transcription factors for gene activation, resulting in decreased cell division.arrow_forwardHuman cells are highly resistant to transformation. Experiments have shown that 5 regulatory circuits (pathways) have to be altered before human cells can grow as tumor cells in immunocompromised mice. State each of these circuits. Explain how the alteration of the protein of that particular circuit leads to uncontrolled growth. the mitogenic signaling pathway controlled by Ras. the cell cycle checkpoint controlled by pRb. the alarm pathway controlled by p53. the telomere maintenance pathway controlled by hTERT. the signaling pathways are controlled by protein phosphatase 2A, which modulates the activity of the mTOR, Myc, β-catenin, and PKB/ Akt signaling proteins.arrow_forward
- Why are stem cells not more abundant in the human body? I learned that stem cells can proliferate into any kind of cell in the body. These cells can be very beneficial for repairing damaged tissues and replacing dead tissue. So, if stem cells have so many uses and benefits why are they not more abundant in the human body? What are the benefits and risks of an increase of stem cells? Do the benefits outweigh the possible problems? Is an increase in stem cell numbers only worth while when an injury has occurred such as in stem cell therapy? Thank youarrow_forwardGenetic tests that detect mutations in the BRCA1 and BRCA2 tumor-suppressor genes 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?arrow_forwardGenetic tests that detect mutations in the BRCA1 and BRCA2 oncogenes are widely available.
