Abstract

The centriole duplication cycle normally maintains number at two centrioles per G1 cell. However, some circumstances can result in an aberrant increase in centriole number. Cells with extra centrioles display extended cell cycle arrest, longer interphase durations, and death, which result in a proliferative disadvantage relative to normal cells.
