Effects of the LRE541 extract on cell cycles of RKO and 7901. a Cell cycle progressions of 7901 and RKO when treated with increasing concentrations of the LRE541 extract for 48 h. b Quantification of living cells distributing in three distinct phases of the cell cycle (G0/G1, S, and G2/M phase). The data are shown as the mean ± SD of three independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001 vs. the control groups
