Effect of Chronic Kidney Disease on Changes in Vasopressin System Expression in the Kidney Cortex in Rats with Nephrectomy

Figure 4

Protein level of V1a and V2 vasopressin receptors and aquaporin 2. (a) V1a vasopressin receptor protein level in the kidney cortex in rats with 5/6 nephrectomy, 2/3 nephrectomy, 1/2 nephrectomy, or control group. CN: control group; N1/2: 1/2 nephrectomy group, N2/3: 2/3 nephrectomy group; N5/6: 5/6 nephrectomy group; V1aR: V1a vasopressin receptor. The bands represent two independent samples from each group of rats. Means ± SE are shown. P<0.001. (b) V2 vasopressin receptor protein level in the kidney cortex in rats with 5/6 nephrectomy, 2/3 nephrectomy, 1/2 nephrectomy, or control group. V2R: V2 vasopressin receptor. Other abbreviations as in (a). The bands represent two independent samples from each group of rats. Means ± SE are shown; P<0.001. (c) Aquaporin 2 protein level in the kidney cortex in rats with 5/6 nephrectomy, 2/3 nephrectomy, 1/2 nephrectomy, or control group. AQP2: aquaporin 2. Other abbreviations as in (a). The bands represent two independent samples from each group of rats. Means ± SE are shown; P<0.001.
