Expression of α1a and α2a AR mRNA in the hypothalamic paraventricular nucleus (PVN) and adrenal medulla; values are normalized to GAPDH expression. Expression of α1a AR mRNA was upregulated in the PVN. Expression of α2a AR mRNA was downregulated in both the PVN and adrenal medulla. Values are mean ± SE. *P < 0.05, **P < 0.01 versus controls (t test.
