Expression of mRNA in the hypothalamus (A–C) and brainstem (D–G) in rats with nocturnal melatonin administration at three concentrations (Mel2, n = 4; Mel10, n = 5 and Mel45, n = 8) and Placebo (P, n = 6) group. Graphs contain unpaired t-tests (WT, n = 4 vs SHR, n = 6) and one-way ANOVA results. AVP arginine vasopressin, GABAAR gamma-Aminobutyric acid A receptor, GAD65 glutamic acid, decarboxylase 65, GAD67 glutamic acid decarboxylase 67, GAT1 gamma-aminobutyric acid transporter, NTS the nucleus tractus solitarii, PVN the paraventricular nucleus, SCN the suprachiasmatic nucleus, SON the supraoptic nucleus. Data are visualised as individual datapoints and arithmetic mean ± the standard error of the mean
