Lithium inhibits proliferation of human esophageal cancer cell line Eca-109 by inducing a G2/M cell cycle arrest

Figure 3 Lithium inhibited the proli-feration of Eca-109 cells by an arrest in G₂/M phase. Eca-109 cells were treated with lithium (20 mmol/L) for 0 h (A) and 24 h (B). Eca-109 cells were harvested and cell cycle profiles were obtained by staining with propidium iodide (PI).
