Abstract

The Wilms' tumor 1 gene, WT1, encodes a zinc‐finger protein that is implicated in the development of Wilms' tumor. Mutant or aberrantly expressed WT1 isoforms have also been described in desmoplastic small round cell tumor, acute leukemias, mesothelioma, breast tumors and melanoma. During early development, WT1 is expressed in the brain and spinal cord, however its role in the malignancies that affect these tissues has not been previously investigated. In our study we have examined neural tumors including brain tumors and neuroblastomas for WT1 expression and for mutations affecting the zinc‐fingers. Although WT1 expression was detected in gliomas, medulloblastomas and neuroblastomas, neither zinc‐finger region mutations nor splicing anomalies affecting the KTS site were detected. We therefore conclude that WT1 does not play a significant role in the etiology of human neural tumors. © 2001 Wiley‐Liss, Inc.

## Abstract Desmoid tumors (aggressive fibromatosis) are locally invasive soft tissue tumors in which β‐catenin/TCF3 mediated Wnt signaling is activated. More than 80% of desmoid tumors contain activating mutations in β‐catenin. It has been shown that the Wnt signaling pathway interacts with Wilms'
