Figure 4.

Quantification and analysis in percentage among subG1, G1, and G2/M phase cell number in HNSCC cell lines.

Notes: The statistical analysis from three independent experiments of Figure 3 regarding the change of the cell cycle in terms of percentages of subG1, G1, and G2/M phases was analyzed and illustrated ([A] OC3 cells; [B] OEC-M1 cells; and [C] FaDu cells). (a) subG1 phase; (b) G1 phase; and (c) G2/M phase. Data represent the mean ± standard error of the mean of three separate experiments. *Significant difference when compared with controls (plain medium) in each cell cycle phase (P<0.05) (Control represents control as plain medium).

Abbreviations: HNSCC, head and neck squamous cell carcinoma; DMSO, dimethyltetrazolium bromide.
