FIG. 7.

The changes in caspase-3 protein expression in MGC803 cells after treatment with berberine and d-limonene, alone and in combination, for 24 and 48 h. The expression of caspase-3 (A) in MGC803 cells was detected by the FITC-conjugated secondary antibody, and FI was measured by laser scanning confocal microscopy. Data presented as mean±SD values of three independent experiments (B). P<.05, ^asignificantly different compared with the control group; ^bsignificantly different compared with the single drug treatments. The bar is 15 μm.
