Wilms tumor 1 (WT1), a tumor suppressor gene, was originally identified in the homonymous renal neoplasm but is also involved in other cancers. Its function is still unclear, since it acts both as a pro- and an anti-oncogene. At least 14 WT1 transcriptional variants have been described; yet most investigations have focused on a small number of isoforms. We describe their structural features and review the evidence of their involvement in cancer with emphasis on neuroblastoma. In future, full characterization of all WT1 isoforms is expected to identify new molecular tumor markers and/or therapeutic targets.

Abstract
Wilms tumor 1 (WT1), a tumor suppressor gene, was originally identified in the homonymous renal neoplasm but is also involved in other cancers. Its function is still unclear, since it acts both as a pro- and an anti-oncogene. At least 14 WT1 transcriptional variants have been described; yet most investigations have focused on a small number of isoforms. We describe their structural features and review the evidence of their involvement in cancer with emphasis on neuroblastoma. In future, full characterization of all WT1 isoforms is expected to identify new molecular tumor markers and/or therapeutic targets.File in questo prodotto:
