Transcription factor Wilms' tumor 1 (WT1) was originally identified as a tumor suppressor for Wilms' tumor, but it is also overexpressed in a variety of cancer cells, suggesting a potential oncogenic function of WT1. It is important to understand molecular mechanisms underlying these dual functions of WT1 in tumorigenesis. In the current study, we report a synergistic role for signal transducer...
The Wilms tumor suppressor gene WT1 (wt1 in mouse) is unique among tumor suppressors because, in addition to its involvement in cancer [1] [2] and various other diseases [3] [4] [5] [6], it has an essential role in the development of certain organs. This is revealed by the phenotype of mice with inactivated wt1 alleles [7]. These animals exhibit a complete failure of kidney and gonad developmen...
The WT1 gene, which is heterozygously mutated or deleted in congenital anomaly syndromes and homozygously mutated in about 15% of all Wilms tumors, encodes tissue-specific developmental regulators. Through alternative mRNA splicing, four main WT1 protein isoforms are synthesized. All isoforms can bind to DNA via their zinc fingers, albeit with different affinities and specificities, and thereby...
The aberrant overexpression of Wilms tumor 1 (WT1) in myeloid leukemia plays an important role in blast cell survival and resistance to chemotherapy. High expression of WT1 is also associated with relapse and shortened disease-free survival in patients. However, the mechanisms by which WT1 expression is regulated in leukemia remain unclear. Here, we report that heat shock protein 90 (Hsp90), wh...
UNLABELLED The Philadelphia chromosome and the resulting BCR-ABL fusion gene represent the hallmark event in chronic myeloid leukemia (CML) and their discoveries radically changed the management of these patients. Currently Wilms tumor 1 gene (WT1) is intensively investigated as high WT1 expression levels have been demonstrated in case of multiple solid tumors and malignant hematological syndro...
Although the WT1 gene was originally isolated as a tumor suppressor gene from Wilms' tumor, oncogenic roles for WT1 have been reported in several tumors. Here, we present new findings of high levels of WT1 expression associated with the suppression of lymph node metastasis in patients with human lung squamous cell carcinoma (SCC). We investigated the effect of down-regulated WT1 gene expression...
Wilms tumor gene (WT1) protein is an attractive target for cancer immunotherapy. We aimed to investigate the feasibility of a combination therapy consisting of gemcitabine and WT1 peptide-based vaccine for patients with advanced pancreatic cancer and to make initial assessments of its clinical efficacy and immunologic response. Thirty-two HLA-A*24:02 patients with advanced pancreatic cancer wer...
BACKGROUND In human breast cancer, a growth status switched from estrogen-dependent to growth factor-dependent is a critical step during development of acquired tamoxifen resistance. However, the molecular mechanisms underlying this switch remain poorly understood. The Wilms' tumor suppressor gene, WT1, encodes a zinc-finger protein WT1 that functions as a transcription regulator. High levels o...
Clinical studies of WT1-targeted cancer vaccine are being performed. However, WT1-specific Th response in cancer patients remains unclear. Using quantitative real-time RT-PCR, we investigated IFN-gamma and IL-10 mRNA expression from Th cells by stimulation with helper peptide WT1(332). Seventeen patients, of whom 10 had achieved stable disease and the remaining 7 had progressive disease, were w...
Rationale: The embryonic epicardium is a crucial cell source of the cardiac fibrous skeleton as well as of the coronary system. Genetic lineage tracing systems based on Wt1 regulatory sequences provided evidence that epicardium-derived cells also adopt a myocardial fate in the mouse. Objective: To define the adequacy of Wt1-based lineage tracing systems for epicardial fate mapping. Methods and ...
