The embryonic epicardium is an important source of cardiovascular precursor cells and paracrine factors that are required for adequate heart formation. Signaling pathways regulated by WT1 that promote heart development have started to be described; however, there is little information on signaling pathways regulated by WT1 that could act in a negative manner. Transcriptome analysis of Wt1KO epi...

BACKGROUND Denys-Drash syndrome (DDS) is associated with mutations of the Wilms' tumour 1 (WT1) gene, and is characterized by pseudohermaphroditism, a progressive glomerulopathy, and the development of Wilms' tumour. More than 90% of patients with DDS who carry constitutional intragenic WT1 mutations are at high risk (90%) for the development of Wilms' tumour. WT1 is a signalling protein with 9...

Breast cancer is the most common cancer among women all over the world. Since the clinical outcome of breast cancer may differ among some women who have the same clinicopathological stage, researchers focused on additional prognostic parameters to predict the tumor behavior. The aim of this study was to investigate the prognostic value of Wilms Tumor 1 (WT1) expression in tumor tissues and to c...

Cyclin A1 is a cell cycle protein that is expressed in testes, brain and CD34-positive hematopoietic progenitor cells. Cyclin A1 is overexpressed in a variety of myeloid leukemic cell lines and in myeloid leukemic blasts. Transgenic cyclin A1 overexpressing mice develop acute myeloid leukemia with low frequency. In this study, we looked for putative target genes of cyclin A1 in hematopoietic ce...

Wilms' tumor gene 1 (WT1) plays complex roles in tumorigenesis, acting as tumor suppressor gene or an oncogene depending on the cellular context. WT1 expression has been variably reported in both benign and malignant peripheral nerve sheath tumors (MPNSTs) by means of immunohistochemistry. The aim of the present study was to characterize its potential pathogenetic role in these relatively uncom...

The Wilms' tumour suppressor gene WT1 encodes a protein involved in urogenital development and disease. The salient feature of WT1 is the presence of four 'Krüppel'-type C(2)-H(2) zinc fingers in the C-terminus. Uniquely to WT1, an evolutionarily conserved alternative splicing event inserts three amino acids (KTS) between the third and fourth zinc fingers, which disrupts DNA binding. The ratio ...

Introduction/Background WT1 gene and its encoded protein are highly expressed in hematological malignancies solid tumors such as cancer of breast, lung, pancreas, ovary prostate (1). WT1-expression is examined by IHC or qPCR, while WT1- ELISA kit also available. We compared serum level (sWT1) with expression ovarian (OC) patients. Methodology studied 30 OC-cases 11 benign cyst...

BACKGROUND/AIM Pancytopenia is caused by acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), aplastic anemia (AA), or by non-hematological diseases. Because Wilms' tumor-1 (WT1) is overexpressed in patients with AML and MDS, its expression level may be helpful for diagnosing these hematological malignancies. PATIENTS AND METHODS We retrospectively investigated the WT1 transcripts in...

The TET2 DNA dioxygenase regulates cell identity and suppresses tumorigenesis by modulating DNA methylation and expression of a large number of genes. How TET2, like most other chromatin-modifying enzymes, is recruited to specific genomic sites is unknown. Here we report that WT1, a sequence-specific transcription factor, is mutated in a mutually exclusive manner with TET2, IDH1, and IDH2 in ac...

Wilms' tumor gene 1 (WT1) expression is a well-known predictor for relapse in acute myeloid leukemia. We monitored WT1 decrement along the treatment course to identify its significant role as a marker for residual disease in acute promyelocytic leukemia (APL) and tried to suggest its significance for relapse prediction. In this single center retrospective study, we serially measured PML-RARa an...
