- Which negative regulatory molecule can trigger cell suicide (apoptosis) if vital cell cycle events do not occur? p53 p21 retinoblastoma protein (Rb) cyclin-dependent kinase (Cdk)In what important way does receptor-mediated endocytosis differ from phagocytosis? It transports only small amounts of fluid It does not involve the pinching off of membrane It brings in only a specifically targeted substance It brings substances into the cell, while phagocytosis removes substances.Cite evidence supporting a long evolutionary history for cell signaling molecules.
- liges 3. Tyrosine kinase receptors are pairs of proteins that span the plasma membrane. On the extracellular side of the membrane, one or more sites are present that bind to signaling ligands such as insulin or growth factors. On the intracellular side, the enas of peptide chains on each protein phosphorylate the other member of the pair, providing active docking sites that initiate cellular responses. The signal is switched off by dissociation of the ligand. For each ligand-receptor system, the equilibrium constant, k, controls the distribution of receptor-bound and unbound ligands. In systems with large values of k, a site is likely to be occupied, even at low concentrations of ligand. When k is small, the likelihood of binding is low, even when the concentration of ligand is high. To initiate a new stimulus response cycle for the receptor, the ligand must dissociate. Larger values of k mean that the receptor is more likely to be occupied and thus unavailable to bind another ligand.…Retinoblastoma: The Hits Just Keep Coming case study Part III – The Second Hit Questions A second hit might occur through epigenetic alterations. In the promoter of RB1, there is a CpG island. Knowing this, how might you predict that a cell could epigenetically inactivate RB1 transcription? A second hit might also occur through loss of heterozygosity (LOH). An example of how LOH may occur by reciprocal crossing over during mitosis is diagrammed in Figure 1 (next page). Discuss and interpret this model with your group. Write a brief explanation of (a) what LOH means and (b) how LOH by mitotic reciprocal crossing over can give rise to a cell lineage with functional loss of the wild-type copy of a tumor suppressor gene. . One of the ways that we know what the RB protein does in cells is that its inactivation is a common priority of tumor-initiating viruses. What advantage would a virus gain by inactivating RB function in its host cell? One example of a DNA virus (a virus that…Cleavage Ligand Precursor Receptor Inactive Receptor Active Cell Membrane 6. The figure above shows a model of a ligand precursor being cleaved to produce an active ligand that binds to a specific receptor.

(A) A change in the cytoskeletal attachment of transmembrane proteins (B) The presence of a large amount of the precursor form of the ligand (C) An increase in the ratio of the number of unsaturated to the number of saturated fatty acid tails of the membrane lipids (D) A mutation in the receptor gene that causes a substitution of a charged amino acid for a nonpolar amino acid in the ligand binding site of the receptor

- Fighting Cancer by Disrupting Mitosis Scientists have identified a number of toxins that disrupt mitosis. These toxins can be used in many different ways – some of them are used during scientific research to arrest the cell cycle at specific points so that the cells can be studied. Others have clinical applications as chemotherapeutic drugs that are useful in the treatment of cancer, as well as other types of disease. Study the list of toxins below, and use the information provided and your understanding of mitosis to answer the questions below. Note: some of these drugs are currently approved for clinical use, while others are still in development. For the purposes of this exercise, assume that all of them are available for use. Drug How it affects mitosis Status of drug Vincristine Prevents polymerization of tubulin Approved Paclitaxel Prevents depolymerization of tubulin and can result in multipolar spindle formation Approved Flavopiridol Blocks Cdk-1.
