PCA based on the methylation profiles of the 57 differentially methylated cytosines (15% threshold) reported in this study (Table 1). Pre- and post-challenge individual sea bass (in red and blue, respectively) differ significantly along PC1 (p < 0.001), but not PC2. The insert illustrates the distribution of individual scores along PC1. Ellipses represent the 95% confidence limits over PC1 and PC2
