SR and SS rats were maintained for 4 weeks on high-salt diet alone (SR+HSD and SS+HSD), or supplemented with corn oil (SS+HSD+CO) or fish oil (SS+HSD+FO) as indicated. (A) ED1 stains of kidney sections. (B) NF-κB EMSA of renal nuclear extracts. (C) COX-2 expression of renal microsomal fractions by Western blot analysis. Values are mean ± SEM (n=10); #P<0.05 vs. SR+HSD, *P<0.05 vs. SS+HSD, +P<0.05 vs. SS+HSD+CO. Insets = representative ED1 stain (A), NF-κB EMSA (B), and COX-2 Western blot (C).
