Guggulsterone induces apoptosis of human hepatocellular carcinoma cells through intrinsic mitochondrial pathway

Figure 2 Guggulsterone alters cell cycle in human HepG2 and L-02 cells. Human HepG2 (A) and L-02 cells (B) were treated with 0 μmol/L, 50 μmol/L and 75 μmol/L of GS for 24 h and the cell cycle was analyzed using flow cytometry, respectively. The histogram showed mean % of cell population in each phase of cell cycle. ^aP < 0.05 or ^bP < 0.01, vs the untreated control group.
