- Describe the effects of the mutation causing the p21 promoter to no longer bind p53 on cell signaling pathways and metabolism or cell cycle control.Describe the molecular mechanisms involved in P53’s role as a tumor repressor proteinWhy is it important to model cancer through the generation of induced pluripotent stem cells ? Explain in detail the main findings.
- illustrate some of the molecular mechanisms leading from loss-of-function mutations in tumor-suppressor genes to increased predispositions to cancer?Why is it important to model cancer through the generation of induced pluripotent stem cells ? Explain in detail the main findings. Please sort as a list.Explain the difference between a proto-oncogene and a tumor suppressor gene.
- Why is it important to model cancer through the generation of induced pluripotent stem cells ? Please explain in detailsAll four genes that are used to reprogram differentiated cells to function as pluripotent stem cells are transcription factors that are also known to be protooncogenes. Many of the early adult stem cell transplant experiments showed the development of cancers in the transplanted tissues. Explain.Describe the differences among embryonic, adult, and inducedpluripotent stem cells.
- Describe error prone polymerases and the process of translesion synthesis (TLS). In regards to tumor biology, what is the mutator phenotype hypothesis? What are some ways in which error-prone polymerases could be targeted for potential anti-cancer treatments?Please explain the role of gene expression in the process of a stem cell differentiating into a neuron rather than a liver cell. Hint: use the terms "serial activation of a subset of genes" and "master regulatory gene".Following are the characteristics of organoids, except: Organoids are in vitro 3D clusters of cells deriving exclusively from primary tissue or stem cells Organoids are capable of self-renewal and self-organization. 2D monolayer cultures are much closer to the in vivo situation than the organoids Spatially restricted cell-fate decisions contribute to self-organization in organoids.
