yeast as a model system for studying cancer and the transition of cells from quiescence to proliferation
Unlocking the secrets of cancer’s origins
Bakers’ yeast is a simple organism – yet the genetic and cellular processes that turn a spoonful of yeast into a frothy mass are the same that start human cells dividing and developing into cancer. By studying yeast as a model of cancer genesis, Dalhousie researchers Dr. Gerry Johnston and his colleague of 30 years, Dr. Rick Singer, have revealed many of the processes that prompt cells to switch from a non-dividing state to a state of rapid cell division. In-depth knowledge of the complex origins of cancer will help researchers develop more effective cancer therapies in the future.
