Expression of Na⁺ pump α₁- and α₂-subunit isoforms and Na⁺/Ca²⁺ exchanger type 1 (NCX1) in arterial myocytes from NT and OH rats. A–H: Western blot analysis of Na⁺ pump α₂-subunits (A and B), Na⁺ pump α₁-subunits (C and D), and NCX1 (E–H) protein expression in smooth muscle cell membranes from mesenteric arteries (A–F) and aortas (G and H) of NT and OH rats. A, C, E, and G: representative blots. All lanes were loaded with 30 μg membrane protein. Summarized data (B, D, F, and H) were normalized to the amount of β-actin and are expressed as means ± SE from 5 (B), 7 (D), 4 (F), and 5 (H) immunoblots (total of 22 rats). ***P < 0.001 vs. NT ASMCs.
