Presentation Transcript

  1. Chapter 17 Cell Division and Apoptosis III

  2. Activation of a cyclin dependent kinase

  3. CdK activity can be suppressed by inhibitory phosphorylation

  4. CdK activity can be suppressed by inhibitory proteins

  5. The Rb protein acts as a brake in mammalian cells

  6. Programmed Cell Death - Apoptosis

  7. Digits in developing mouse paw are formed through apoptosis cells undergoing apoptosis

  8. Apoptosis causes tadpole to lose tail

  9. Necrosis vs. apoptosis

  10. DVD clip 77

  11. Caspase cascade occurs during apoptosis

  12. Procaspase is activated by an active caspase

  13. 4 types of intercellular signaling

  14. An animal cell depends on extracellular signals to survive or divide

  15. An animal cell depends on extracellular signals to differentiate. Without extracellular signals the cell will die

  16. Platelet derived growth factor was the first mitogen isolated stimulates cell division during wound healing

  17. Mitogens stimulate G1-Cdk and G1/S-Cdk activities

  18. Ras is activated by tyrosine kinase

  19. p27 suppresses CdK activity

  20. The Rb protein acts as a brake in mammalian cells

  21. Excessive stimulation of mitogenic pathways leads to cell cycle arrest or apoptosis

  22. Cell growth like cell division is also stimulated by extracellular signals

  23. Comparison of nerve cell size vs. lymphocyte size

  24. Fresh medium stimulates cell growth by adding mitogens

  25. Many types of normal animal cells need anchorage to grow and proliferate

  26. cell on small patch cell spread on large patch

  27. Myostatin inhibits proliferation of skeletal muscle cells
