Abstract excerpt
Sinonasal glomangiopericytoma (SN-GPC) is an uncommon mesenchymal tumor with myoid differentiation. Recently, mutations in exon 3 of the gene coding for β-catenin (CTNNB1) and its nuclear expression were discovered in SN-GPC. β-catenin protein is a key regulatory molecule of the canonical Wnt signaling pathway. The expression of β-catenin target proteins is not well characterized in SN-GPC. We examined three...
