mRNA expression in a mouse model of lupus nephritis’ kidney. ^a–d The same letters indicate no significant differences, whereas different letters show significant differences between the groups at the P<0.05 level. The following tables and figures are the same. TGF-β1: transforming growth factor beta 1; VEGF: vascular endothelial growth factor; NF-κB: nuclear factor kappa-B; IκB-α: inhibitor of nuclear factor kappa-B alpha; ICAM-1: intercellular cell adhesion molecule-1; VCAM-1: vascular cell adhesion molecule-1
