Abstract

BACKGROUND: The Wnt/beta-catenin and cAMP signaling pathways play an important role in adrenal cortex tumorigenesis. Somatic activating mutations of the beta-catenin gene (CTNNB1) are the most frequent genetic defects identified both in adrenocortical adenomas (ACAs) and adrenocortical cancers (ACCs). PRKAR1A mutations leading to cAMP pathway dysregulation are observed in primary pigmented nodular adrenocortical diseases (PPNADs) and some sporadic ACAs. OBJECTIVE: The objective of the investigation was to study Wnt/beta-catenin dysregulation in adrenocortical tumors (ACTs) with cAMP pathway genetic alteration and search for secondary CTNNB1 somatic mutations in heterogeneous tumors. PATIENTS AND METHODS: Nine PPNADs, including five with macronodules, three ACAs with PRKAR1A somatic mutations, and one heterogeneous tumor with ACC developed within an ACA, were studied by immunohistochemistry and DNA sequencing. RESULTS: beta-Catenin accumulation was observed in all PPNADs, ACAs with PRKAR1A mutations, and the ACC component of the heterogeneous tumor. CTNNB1 somatic activating mutations were found in the macronodule of two of the five macronodular PPNADs, in one ACA with a PRKAR1A somatic mutation, and in the malignant part of the heterogeneous ACT. CONCLUSIONS: The Wnt/beta-catenin pathway is activated in PPNADs and ACAs with PRKAR1A mutations, suggesting a cross talk between the cAMP and Wnt/beta-catenin pathways in ACT development. In addition, the occurrence as an additional hit of a CTNNB1 somatic mutation is associated with larger or more aggressive ACTs. This underlines the importance of the Wnt/beta-catenin pathway in adrenal cortex tumorigenesis and the importance of genetic accumulation in the progression of ACTs.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
