A review of the Wilms' tumor 1 gene (WT1) and its role in hematopoiesis and leukemia

Abstract

One of the first clones of the Wilms tumor 1 (WT1) gene, WT33, was isolated from a B cell leukemia cell line in 1990. Now, 12 years on, WT1 has emerged as a potentially important target for antileukemic therapies. Our understanding of the role that WT1 plays during normal hematopoiesis is still limited, and there is a large amount of conflicting data concerning the precise manner in which WT1 gene expression contributes to leukemogenesis. However, interest in this field has intensified in the past 5 years. This review surveys the progress made in this area.
