You are studying the effects of potential anti-cancer drugs on the actin cytoskeleton of cells in culture. You notice that factor X causes the actin fibers to completely depolymerize. Factor Y causes large crosslinked networks of fibers to form . Factor Z causes large parallel fibers to form. Treadmilling and the development of a GTP cap are important characteristics of growing microtubules.
Colchicine inhibits microtubule formation while taxol stabilizes microtubules.
Axons and dendrites have different orientations of their microtubules. Which motor protein is likely to mediate transport of a vesicle towards the distal tip of an axon. Describe the 4 steps necessary for a cell to move. Most cancer cells divide rapidly and do not respond to certain checkpoint controls. One factor that scientists try to use in cancer therapeutics is to make cancer cells more checkpoints defective than they already are.
