Urotensin II peptide and urotensin II receptor protein were investigated with immunohistochemistry and immunoblotting. To identify urotensin II-related and urotensin II receptor-related pathways, a whole transcriptome analysis was used. The adrenocortical effects of urotensin II receptor activation were also assessed by urotensin II infusion with\/without the urotensin II receptor antagonist palosuran in rats.<\/jats:p><jats:p>Results: Urotensin II was more expressed in pheochromocytoma than in aldosterone-producing adenoma tissue; the opposite was seen for the urotensin II receptor expression. Urotensin II receptor activation in vivo in rats enhanced (by 182 \u00b1 9%; P &amp;lt; 0.007) the adrenocortical expression of immunoreactive aldosterone synthase.<\/jats:p><jats:p>Conclusions: Urotensin II is a putative mediator of the effects of the adrenal medulla and pheochromocytoma on the adrenocortical zona glomerulosa.
