Peroxisome proliferator-activated receptor gamma ligands inhibit cell growth and induce apoptosis in human liver cancer BEL-7402 cells

Figure 1 Concentration and time effect of 15d-PGJ2 or TGZ on growth of BEL-7402 cells. (A) BEL-7402 cells were incubated with 20 µM 15d-PGJ2 or TGZ for 12, 24, 48, 72, 96 h. (B) BEL-7402 cells were incubated with various concentrations of 15d-PGJ2 for 48 h; (C) BEL-7402 cells were incubated with various concentra-tions of TGZ for 48 h. The value was represented as mean ± SEM (n = 3). ^aP < 0.05 and ^bP < 0.01 versus corresponding control group.
