TV arrests cells at G₂/M phase and TM extends S phase. HeLa cells were treated with TV (10 µM), TM (2.5 µM), DMSO (D), or n-butanol (B) for 12 and 24 h. DNA was quantified by flow cytometry of PI-stained cells. (A) One representative cell cycle profile per treatment is shown. (B) Relative proportion of cells in phases are indicated as means (n = 3).
