Effects of VAS compounds on the PKC/NOX downstream signaling pathway. (A) Washed platelets (3.6 × 108 cells/ml) were pre-incubated with DMSO (solvent control), VAS compounds (2–10 μM), or Ro 31-8220 (2 μM) following stimulation with PDBu (150 nM) to trigger platelet aggregation. (B) The statistical analysis in (A). (C) After the reaction, platelet lysates were directly collected, and then subjected to Western blotting. Specific antibodies were used to detect PKC, IKKβ, and p38 MAPK. (D,E) Luciferase/luciferin and FITC-P-selectin antibody were used to detect ATP release and P-selectin using a microplate reader and flow cytometry, respectively. Data (B,D) are presented as means ± S.E.M. (n = 3). *p < 0.05, **p < 0.01, and ***p < 0.001, compared with the DMSO (solvent control) group. Data (C,E) are presented as means ± SEM (C, n = 4; E, n = 3). ***p < 0.001, compared with the resting group. ##p < 0.01 and ###p < 0.001, compared with the PDBu-treated (positive control) group. Comparisons were made by ANOVA.
