Mutations in the Wilms' tumor gene, WT1, can lead to syndromic steroid-resistant nephrotic syndrome and isolated steroid-resistant nephrotic syndrome. WT1 mutations have been identified in the majority of children with Denys-Drash or Frasier syndrome. WT1 mutations have not previously been identified in boys with sporadic isolated steroid-resistant nephrotic syndrome, but, recently, four boys w...
To evaluate if WT1 expression may predict relapse after allo-SCT, we analyzed WT1 levels on peripheral blood (PB) and bone marrow (BM) before and after allo-SCT in 24 AML patients with WT1 overexpression at diagnosis. Five copies of WT1/ABL × 10(4) from PB were identified as the threshold value that correlated with relapse after allo-SCT. The same correlation was not identified when WT1 express...
BACKGROUND The Wilms' tumor gene WT1 is overexpressed in endometrial cancer. Although recent studies have revealed that WT1 is a new prognostic factor, it remains unclear whether WT1 plays a pathophysiological role including cell proliferation. PATIENTS AND METHODS A series of 70 endometrial cancer patients who had undergone a curative resection was studied by immunohistochemistry to determin...
PURPOSE The Wilms' tumor antigen 1 (WT1) is overexpressed in several leukemias and solid tumors, but there is currently limited information regarding its role in prostate cancer. This study aimed to investigate WT1 expression in prostate cancer, and to determine the number and function of WT1-specific T cells in the peripheral blood of patients. EXPERIMENTAL DESIGN Immunohistochemistry was us...
The Wilms' tumor 1 (WT1) gene encodes a zinc finger which appears to be a transcriptional activator or repressor for many genes involved in cell differentiation, growth and apoptosis. In order to determine the relationship between WT1 and related proteins, WT1 was silenced with small interfering RNA (siRNA) and the protein expression pattern was analyzed by proteomics analysis including one-dim...
Although the zinc finger transcription factor Wt1 has been linked to female fertility, its precise role in this process has not yet been understood. We have sequenced the WT1 exons in a panel of patients with idiopathic infertility and have identified a missense mutation in WT1 in one patient out of eight. This mutation leads to an amino acid change within the zinc finger domain and results in ...
Wilms' tumour suppressor gene, WT1, is mutated/deleted in approximately 15% of Wilms' tumours, highly expressed in the majority of other cancers and is essential for normal embryonic development. The gene encodes multiple isoforms of a zinc-finger (ZF) protein with diverse cellular functions, in particular participating in both transcriptional and post-transcriptional gene regulation. Physical ...
Wilms' tumor (WT) is associated with loss of heterozygosity at chromosome 11p13, the site of the Wilms' tumor suppressor gene, WT1. Although the preferential loss of maternal alleles suggested that differential allelic expression of WT1 might occur, this has not been evident in normal fetal tissues or WTs. In this study, we show that the WT1 antisense regulatory region is differentially methyla...
Azoospermia is one of the major reproductive disorders which cause male infertility in humans; however, the etiology of this disease is largely unknown. In the present study, six missense mutations of WT1 gene were detected in 529 human patients with non-obstructive azoospermia (NOA), indicating a strong association between WT1 mutation and NOA. The Wilms tumor gene, Wt1, is specifically expres...
BACKGROUND The product of the Wilms' tumor gene, WT1 protein, is a tumor antigen for various kinds of cancer, and WT1 peptide-based cancer immunotherapy is widely anticipated as a new possibility for cancer treatment. The aim of this study was to investigate the expression of WT1 from quantitative and morphological perspectives in oral squamous cell carcinoma (OSCC), the most widespread maligna...
