1603MED cells were treated with DMSO (vehicle, black), with LY364947 (red) or with SB431542 (orange). Cell cycle analysis by FACS measuring BrdU incorporation and 7AAD labelling at 48 hours upon inhibition. The percentage of cells in the different phases of the cell cycle is represented (G0/G1, S and G2/M phases). Bars represent the mean ± SD. Number of replicates is n≥3.
