Abstract
AbstractPrimary aldosteronism (PA) is the most common cause of secondary hypertension with a prevalence of 5–10% in unreferred hypertensive patients. Aldosterone producing adenomas (APAs) constitute a large proportion of PA cases and represent a surgically correctable form of the disease. The WNT signaling pathway is activated in APAs. In other tumors, a frequent cause of aberrant WNT signaling is mutation in theCTNNB1gene coding for β-catenin. Our objective was to screen forCTNNB1mutations in a well-characterized cohort of 198 APAs. SomaticCTNNB1mutations were detected in 5.1% of the tumors, occurring mutually exclusive from mutations inKCNJ5, ATP1A1, ATP2B3andCACNA1D. All of the observed mutations altered serine/threonine residues in the GSK3β binding domain in exon 3. The mutations were associated with stabilized β-catenin and increased AXIN2 expression, suggesting activation of WNT signaling. By CYP11B2 mRNA expression, CYP11B2 protein expression and direct measurement of aldosterone in tumor tissue, we confirmed the ability for aldosterone production. This report provides compelling evidence that aberrant WNT signaling caused by mutations inCTNNB1occur in APAs. This also suggests that other mechanisms that constitutively activate the WNT pathway may be important in APA formation.
