- Overexpression of the Myc protein is a common feature of many types of cancer cells, contributing to their excessive cell growth and proliferation. By contrast, when Myc is overexpressed in most normal cells, the result is not excessive proliferation, but cell-cycle arrest or apoptosis.Which one of the following statements provides the most likely explanation for why overexpression of Myc can have such different outcomes in normal cells and in cancer cells? A. Normal cells contain checks and balances that prevent Myc-induced proliferation. B. In normal cells, Myc protein acts as a mediator in cell-cycle arrest and apoptosis. C. The target protein for Myc-induced proliferation is missing from most normal cells. D. In normal cells, when Myc is overexpressed, the excess Myc protein precipitates.How do somatic stem cells differ from embryonic stem cells?Cell specializations are usually a modification or elaboration of one of the basic cell functions. (True or fa1se?)
- New treatments for several conditions are being developed using stem cells in medical waste, such as biopsy material, teeth, menstrual blood, umbilical cords, and fatty tissue removed in liposuction. For example, fat samples from injured horses are used to grow stem cells to treat tendon injuries. Explain how the two defining characteristics of stem cells enable them to be used to replace damaged or diseased tissue, so that the new tissue functions as opposed to forming a scar.Define stem cells, and describe their two key properties.TGF-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…
