Figure Lengend Snippet: Effect of PARs silencing on FXa-mediated CCL2 and IL6 expression in human CFs ( A , B ; n = 8–9). Before exposure to FXa (100 nM), human atrial CFs were transfected with 10 μM of either scrambled F2R (PAR-1) or F2RL1 (PAR-2) specific siRNA and incubated for 48 h. Gene expression was measured by RT-qPCR after 4 h of incubation with FXa. Data were normalized to the housekeeping gene Cyclophilin-A. Statistical analysis was performed using the non-parametric Friedman test for paired samples ( CCL2 : overall p < 0.001; IL6 : overall p < 0.001) and Dunn’s multiple comparison test (** p < 0.01, **** p < 0.0001). Effect of silencing on F2R (PAR-1) and F2Rl1 (PAR-2) gene expression ( C , D ; n = 14). Data were analysed using the non-parametric Wilcoxon test for paired samples (*** p < 0.001). Effect of FXa inhibition by rivaroxaban on CCL2 and IL6 expression in human CFs ( E , F ; n = 4). Statistical analysis was performed using the non-parametric Friedman test for paired samples ( CCL2: overall p < 0.001; IL6: overall p < 0.001) and Dunn’s multiple comparison test (* p < 0.05). Results are expressed as median bars, with dots indicating individual human CF isolations.
Article Snippet: Human CFs (200 cells/cm 2 ) were seeded in 96-well plates, cultured for 24 h, and serum-starved for 24 h. Subsequently, cells were incubated with human FXa (100 nM) with or without PAR-1 antagonist (1 µM, SCH79797, Tocris, Bioscience, Bristol, UK).
