Effects of bilateral nephrectomy (Nx) or sham operation (Sham) on eGFP in the PVN (A), SON (B), and SCN (C) in AVP-eGFP transgenic rats. Sections were obtained from untreated (A–C-a), sham-operated (A–C-b–d), and bilateral-nephrectomized rats (A–C-f–h) at 3, 12, and 20 h after treatment (each group at each time point, n = 6). Schematic anatomic representation of the nuclei (green shading) adapted from the rat brain atlas (A–C-e). OT optic tract, 3V third ventricle, pPVN parvocellular division of PVN, mPVN magnocellular division of PVN. Scale bar 100 µm
