Microarray data was validated by performing qRT-PCR on mRNA levels of chemokine (C–C) ligand 2 (Ccl2), chemokine (C–C motif) ligand 4 (Ccl4), chemokine (C-X-C motif) ligand 2 (Cxcl2), v-Fos FBJ murine osteosarcoma viral oncogene homologue (Fos), matrix metallopeptidase 13 (Mmp13), nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, zeta (Nfkbiz), tumor necrosis factor (Tnf-α), and RAB3A, member RAS oncogene family (Rab3a) (n = 3; *p < 0.05, **p < 0.01, ***p < 0.001 compared to the PBS-treated group).
