Document Summary

Physiological basis of therapeutics: lecture 5 : cell cycle, cell division, and cancer, a cell"s life cycle. Internal factors (m-phase promoting factor, mpf: extracellular chemical factors (growth factors, decreased cell division, repressor genes (faulty repressors cause cancers, worn out telomeres (terminal dna segments) Monday, august 20, 2018: cyclin-cyclin-dependent kinase (cdk) complex, phosphorylation = adding phosphate to something, action of kinase, cyclin binds to kinase and helps determine when the kinase is turned. On/off: cell cycle checkpoints, normal cells have highly-regulated cell cycles, several key checkpoints regulate the cell cycle, orange t shaped lines stand for block/inhibits , cells progress through cycle with serveral checkpoints. For that reason one breakthrough "cure for cancer" is probably not likely to come along. There probably won"t be one date in history when people remember that the cure for cancer was announced just as infectious diseases weren"t conquered on one particular day.
