Figure 5. Effects of IND-2 on mitochondrial membrane potential and DNA fragmentation.
(A). HCT-116 cells in complete medium were exposed to IND-2 (0, 1, or 10 [.proportional]M) for 4 hr. Cells were then treated with the reagents of the MitoTracker Red and Alexa Fluor 488 annexin V kits for flow cytometry. Representative results from two independent experiments, each performed in triplicate, are shown. (B) IND-2 induced DNA damage in HCT-116 cells. Chromosomal DNA was extracted from HCT-116 cells and resolved on a 1% agarose gel at 40 V for 6 hr. Lane 1: ‘M’, Marker; Lanes 2–3: untreated HCT cells, 500 ng and 1 μg, respectively; Lanes 4–5: HCT cells incubated with IND-2 (2.5 μM) for 6 hr.
