Characterization of differential gene expression in adrenocortical tumors harbouring β-catenin (CTNNB1) mutations.


ABSTRACT: Mutations of β-catenin gene (CTNNB1) are frequent in adrenocortical adenomas (AA) and carcinomas (ACC). However, the target genes of CTNNB1 have not yet been identified in adrenocortical tumors. Our objective was to identify genes de-regulated in adrenocortical tumors harbouring CTNNB1 genetic alterations. We compared gene expression profiles of AA with (n: 3) and without (n: 4) CTNNB1 mutations using Affymetrix arrays.

<h4>Background</h4>Mutations of β-catenin gene (CTNNB1) are frequent in adrenocortical adenomas (AA) and adrenocortical carcinomas (ACC). However, the target genes of β-catenin have not yet been identified in adrenocortical tumors.<h4>Objective</h4>Our objective was to identify genes deregulated in adrenocortical tumors harboring CTNNB1 genetic alterations and nuclear accumulation of β-catenin.<h4>Methods</h4>Microarray analysis identified a dataset of genes that were differently expressed betwe  ...[more]
