Fig. 6From: Salidroside protects against foam cell formation and apoptosis, possibly via the MAPK and AKT signaling pathwaysEffect of salidroside pretreatment on ox-LDL–induced THP1 cell apoptosis. (a) THP1 cell apoptosis was determined by flow cytometry. The X and Y axes represent Annexin V and PI fluorescence, respectively; (b) The mean percentage of apoptotic THP1 cells measured by flow cytometry. THP1 cells were treated with or without salidroside for 5 h, followed by treatment with ox-LDL (150 μg/mL) for another 24 h. Data are expressed as mean ± standard deviation (SD). # p < 0.05 indicates significant difference from the control groupBack to article page
