Fig 5. Effect of Iron-Restricted Pair-Feeding on Renal MR Signaling in CKD Rats.

Fig 5

(A) The urinary sodium and potassium excretion ratio, (B) renal nuclear expression of MR, and (C) renal SGK1 gene expression at 16 weeks after a 5/6 nephrectomy in the Control-PF (white bar), CKD-PF (black bar), and CKD-IRPF (gray bar) groups (n = 6 in each group). MR, mineralcorticoid receptor; CREB, cAMP response element binding protein; SGK1, serum and glucocorticoid regulated kinase 1; Control-PF, Sham-operated rats fed a normal pair-feeding diet; CKD-PF, 5/6 nephrectomized rats fed a normal pair-feeding diet; CKD-IRPF, 5/6 nephrectomized rats fed an iron-restricted pair-feeding diet. *p < 0.05 versus the Control-PF group, p < 0.05 versus the CKD-PF group.
