R2 induced mitochondrial membrane potential depolarization (a and b) in AGS-EBV cells. AGS-EBV cells were cultured in R2 (0, 5, 10, 20 μg/mL) for 24 h. DMSO treatment was used as vehicle control. Cells were labeled with DIOC6 and then analyzed by flow cytometry to detect the levels of mitochondrial membrane potential. Relative expression levels were showed in b. Results obtained from a representative experiment are shown (n = 3). ** p < 0.01 was considered statistically significant
