Correlation between fold regulations of chemokines. The correlation between gene expression fold regulation (FR) values of a Ccl2/Ccl7, b Ccl17/Ccl22, c Ccl3/Ccl4, d Ccl3/Il1a, e Ccl3/Il1b, f Ccl3/Il1rn, g Ccl4/Il1a, h Ccl4/Il1b, i Ccl4/Il1rn, j Il1a/Il1b, k Il1a/Il1rn, and l Il1b/Il1rn is illustrated. The individual data points display the FR values of each dose groups 0.1, 0.3, 1.0, and 3.0 mg/m3 CeO2 per time point (day 1, 28, 90). R = Spearman’s correlation coefficient, level of significance p ≤ 0.05; Spearman’s rank correlation analysis
