Figure 4: (A) The number of early and late apoptotic cells (from total 10,000 cells) of HT-29 cells was increased following FKC treatment for 24 and 48 h. *P<0.05 compared to the control. (B) The effect of FKC on the mitochondrial membrane potential (Δ Ψm) of HT-29 cells. Δ Ψof HT-29 cells was significantly reduced by FKC in a dose- and time-dependent manner. *P<0.05 compared to the control. (C) FKC induces DNA fragmentation in HT-29 cells. Percentages of HT-29 cells that showed positive DNA fragmentation are represented in the upper quadrant from a dot plot.
