Major isoforms of WT1--products of the tumour suppressor gene WT1, implicated in predisposition to Wilms' tumour--may preferentially interact with splicing factors, suggesting a role for WT1 in RNA processing.
OBJECTIVE Myelodysplastic syndromes (MDS) are a group of hematological neoplasms associated with ineffective hematopoiesis and that transform to acute leukemia. Distinguishing MDS from other cytopenias is sometimes difficult even for trained hematologists. WT1, the gene mutated in Wilms' tumor, was found expressed in acute myeloid leukemia and MDS. The amount of WT1 in peripheral blood and bone...
The Wilms' tumor 1 (WT1) gene is one of the regulating factors in cell proliferation and development. It is a double-functional gene: an oncogene and a tumor suppressor. This gene was found to be highly expressed in many leukemic cell lines and in patients with acute myeloid leukemia. In the present study, we demonstrated that the WT1 gene was commonly expressed in leukemic cell lines apart fro...
The identification of human Wilms' tumor gene 1 (WT1) protein-derived cytotoxic T lymphocyte (CTL) epitopes and the in vivo efficacy of WT1 peptide-based immunotherapy in a mouse model were reported in 2000. This successful basic research led to clinical studies of a WT1 peptide vaccine, and a positive impact on clinical response was first demonstrated in 2003 in the form of a reduction in blas...
The Wilms tumor suppressor WT1 encodes a zinc finger transcription factor that is expressed in glomerular podocytes during a narrow window in kidney development. By immunoprecipitation and protein microsequencing analysis, we have identified a major cellular protein associated with endogenous WT1 to be the inducible chaperone Hsp70. WT1 and Hsp70 are physically associated in embryonic rat kidne...
To evaluate the incidence and clinical impact of WT1 gene mutations in younger adult patients with cytogenetically normal acute myeloid leukemia (CN-AML), sequencing of the complete coding region was performed in diagnostic samples from 617 patients who were treated on 3 German-Austrian AML Study Group protocols. WT1 mutations were identified in 78 (12.6%) of the 617 patients; mutations cluster...
Although tumour suppressor gene hypermethylation is a universal feature of cancer cells, little is known about the necessary molecular triggers. Here, we show that Wilms' tumour 1 (WT1), a developmental master regulator that can also act as a tumour suppressor or oncoprotein, transcriptionally regulates the de novo DNA methyltransferase 3A (DNMT3A) and that cellular WT1 levels can influence DNA...
The zinc finger transcription factor, WT1, regulates many growth control genes, repressing or activating transcription depending on the gene and cell type. Based on earlier analyses of the effect of WT1 on androgen responsive genes, we hypothesized that there may be an interaction between the androgen signaling pathway and WT1, such that the commonly used Renilla luciferase control vectors were...
The WT1 tumor suppressor gene encodes a zinc finger transcription factor expressed in differentiating glomerular podocytes. Complete inactivation of WT1 in the mouse leads to failure of mesenchymal induction and renal agenesis, an early developmental phenotype that prevents analysis of subsequent stages in glomerular differentiation [1]. In humans with Denys-Drash Syndrome, a heterozygous germl...
Wilms' tumor or nephroblastoma is believed to arise from embryonic nephrogenic rests of multipotent cells that fail to terminally differentiate into epithelium and continue to proliferate. The WT1 tumor suppressor gene, a transcription factor controlling the mesenchymal-epithelial transition in renal development, is mutated in 10% to 15% of Wilms' tumors. This potentially explains the disordere...
