Fig. 4.
High salt (HS) intake has no significant effect on the molecular clock components of the renal cortex. mRNA expression (copy count, n = 5) in 4-h intervals of Cry1 (A and B), Cry2 (C and D), Per1 (E and F), and Per2 (G and H) in the renal cortex of control and ETB-deficient (ETB def) rats maintained on normal salt or HS diet for 2 wk is shown. Symbols represent means ± SE, and lines represent cosinor analysis (Table 2).
