Mechanism of apoptotic effects induced selectively by ursodeoxycholic acid on human hepatoma cell lines

Figure 1 A: Cell cycle distribution of BEL7402 treated with UDCA (0. 8 mmol/L) for 48 h. The cell cycle distribution changed, the proportion of G₀-G₁ phase increased significantly (P < 0.05) and the proportion of S phase and G₂-M phase decreased significantly (P < 0.05); B: Cell cycle distribution of L-02 cells treated with UDCA (0.8 mmol/L) for 48 h. The cell cycle distribution of L-02 cells does not change.
