aCell cycle phase was calculated from cell cycle distributions based on flow cytometric analysis.										bDoubling time was calculated from cell cycle distributions based on growth rates.										bCell cycle distributions shown in Figure 7A were corrected using BrdU incorporation values of 58.6% (c-myc+/+ cells), 28.4% (c-myc−/− cells), and 39.2% (A2 cells), respectively. These values were determined by pulse labeling of BrdU as in Materials and methods.										dCorrected cell cycle distributions were combined with growth rate values (doubling time).										eG1 phase duration from data in Figure 7B. Values for 50% labeling index are shown.
