Figure Lengend Snippet: Fig. 7 Selective A2B receptor blockage with PSB603 (100 nM) attenuates NECA-induced overgrowth of cardiac fibroblasts (CFs) from the RV of MCT-treated rats. NECA (10 μM) with or without PSB603 (100 nM) was incorporated in culture media throughout the whole assay. The ordinates represent NECA- and/or PSB603-induced changes in cell growth (MTT assay, A) and type I collagen produc- tion (Sirius Red assay, B) compared to the control situation using the same cell batch in the absence of test drugs at culture days 7, 14, 21, and 28. Zero represents the similarity between the two values (drug vs. control); positive and negative values represent facilitation or inhi- bition of either cell growth or type I collagen production relative to control data obtained at the same time points. Each bar represents pooled data from 5 (CTRL) and 6 (MCT) animals; 3 to 4 replicas were performed for each experiment. The vertical bars represent SEM. *p < 0.05 (ANOVA, one-way analysis of variance) represents significant differences from control values obtained in the absence of test drugs; #p < 0.05 (ANOVA, one-way analysis of variance) repre- sents significant differences compared to the effect of NECA alone
