Figure 2. Lithium chloride induces cell cycle arrest in PANC-1 cells and AsPC-1 cells.

PANC-1 cells (A) and AsPC-1 cells (B) were treated with 20 mM LiCl and analyzed by flow cytometry with PI staining. Data (Mean ± SEM) were representative of three independent experiments. P values are indicated by asterisks (relative to control): *P<0.05, **P<0.01, ***P<0.001.
