Figure 1. Effect of LBH589 on cell cycle distribution of A549 and PC9 cells.

A, The asynchronously growing cells were incubated in medium with 5% FCS for 24 hours in the absence (control, C) or presence (L) of LBH589. The percentage of cells in different phases of the cell cycle was determined by flow cytometric analysis. B, Histogram representation of cell cycle data determined by flow cytometric analysis.
