A: Western blot analysis of kidney angiotensin type-1 receptor (AT₁R) protein expression following 24 h of systemic 5% dextrose in water (sD₅W) + renal interstitial (RI) D₅W (open bar, group 1), systemic angiotensin II (sANG II) + RI scrambled (SCR) siRNA (solid bar, group 3), and sANG II + RI ghrelin receptor (GR) siRNA (shaded bar, group 4) infusions. Blot is normalized to β-tubulin. B: serum aldosterone measurements in response to the same treatments in A. Results are reported as ng/ml. Data represent means ±  SE. *P < 0.05 from sD₅W + RI D₅W and sANG II + RI GR siRNA treatments.
