Key Event Description
?
The disruption of the cell cycle leads to a decrease in the cell number. The cell cycle consists of G1, S, G2, M, and G0 phase. The cell cycle regulation is disrupted by the cell cycle arrest in certain cell cycle phase. The histone gene expression is regulated in cell cycle phases [Heintz et al., 1983].
How It Is Measured or Detected
?
The percentage of cells at G1, G0, S, and G2/M phases can be detected by flow cytometry [Li et al., 2013]. Cell cycle distribution was analyzed by fluorescence-activated cell sorter (FACS) analysis with a Partec PAS-II sorter [Zupkovitz et al., 2010]. The four cell cycle phases in living cells can be measured with four-color fluorescent proteins using live cell imaging [Bajar et al., 2016]. The incorporation of [3H]deoxycytidine or [3H]thymidine into cell DNA during S phase can be monitored as DNA synthesis [Heintz et al., 1982].
Domain of Applicability
?
The histone gene expression alters in each phase of cell cycle in human HeLa cell (Homo sapiens) [Heintz et al., 1982].
