  • The data are expressed as a percentage of acridine orange- and ethidium bromide-stained apoptotic cells, mean ± SE (n = 6 replicates).

  • b,c,d The data were analyzed by factorial analysis of variance. The method of post hoc multiple comparisons was used to determine statistical significance among all treatment conditions (i.e., dose and type of selenium compound) within a cell line. Values that do not share common superscripts are significantly different from each other (P < 0.05).
