#Unit 4. Cell Communication and Cell Signaling

  1. Tumors as well as normal tissues are likely to consist of small number of stem cells that have self-renewal capability and multipotentiality, precursor cells that have limited proliferative potency, and differentiated cells.

  2. Cancer stem cells are thought to be transformed from tissue specific stem cells, precursor cells and/or differentiated cells by genetic/epigenetic mutations.

  3. Cancer stem cells exist in special microenvironment “niche” and seem to keep their resistance to a variety of anti-cancer treatment methods.

  4. Cancer stem cells do not need microenvironment (hypoxic) for the maintenance of stemness, tumorigenesis, and resistance to anti-cancer treatments, chemotherapy and irradiation.

Following statements are regarding to the protein phosphatase Cdc14 function in budding yeast.

A. In budding yeast, the protein phosphatase Cdc14 throws the switch between two mutually antagonistic states during anaphase.

B. Cdc14 is kept inactive during most of the cell cycle, but is activated during anaphase by a GTPase signaling pathway known as the mitotic exit network.

C. Mitotic exit network is unresponsive to spindle position and becomes active in anaphase.

D. Cdc14 phosphatase activated by the activation of protein kinase cascade.

E. Cdc14 dephosphorylates APC/CCdh1 and Sic1 to promote mitotic cyclin degradation

and mitotic CDK inactivation, respectively. This process leads to exit from mitosis.
