inflammatory cytokineinduced WT1 overexpression may promote the formation of psoriatic skin lesions via regulation of the proliferation and apoptosis of keratinocytes.
BRG1, the essential ATPase subunit of the SWI/SNF chromatin-remodelling complex, is required for expression of Wilms' tumour 1 (Wt1), fetal epicardium-derived cell activation and subsequent differentiation into coronary smooth muscle, and restoration of Wt1 activity upon myocardial infarction.
Study shows that WT1 expression in breast cancer (BC) occurs at low frequency. Also, the results demonstrate that WT1 plays a role in regulating the epithelial-mesenchymal balance of BC cells and that WT1-expressing tumors are mainly associated with a mesenchymal phenotype. WT1 gene expression also correlates with CYP3A4 levels and is associated with poor response to taxane treatment.
Study provides evidence that the renal specific phenotype of nail patella-like renal disease associated with LMX1B R246Q mutation may be due to dominant negative effect on WT1(- KTS) specific isoforms causing a disruption of the WT1 isoform ratio and subsequent decrease in key podocyte related genes.
MDS and acute myeloid leukemia were the major target diseases to provide proof of concept for the therapeutic potential of the WT1 peptide vaccine. WT1 vaccination-induced clinical responses or usefulness were also shown for chronic myeloid leukemia, multiple myeloma, and acute lymphoblastic leukemia, as well as various types of solid cancers. Non-Hodgkin's lymphoma and myeloproliferative neoplasms may be target diseases
Total heterogeneous methylation of WT1 conferred a significantly higher risk of Colorectal Cancer.The gene methylation status of blood leukocytes may be associated with CRC risk.
excessive expression of WT1 was detected in ovaries of Polycystic Ovary Syndrome patients providing novel insights into the relationship between hyperandrogenism and polycystic ovaries of PCOS and WT1.
WT1 isoforms containing or lacking an insert, KTS, between zinc finger 3 and 4 have different binding patterns to both DNA and RNA targets in acute myeloid leukemia. (Review)
study identifies a novel mechanism of hepatocellular carcinoma inhibition through beta-catenin-independent Wnt signalling, which is regulated by WT1-associated LEF1 repression. The study also highlights mangiferin as a promising Wnt inhibitor for HCC treatment.
our data demonstrate that WT1 protein undergoes proteolytic processing by caspase-3 in chemotherapeutic drugs-induced apoptosis. This processing is associated with a reduction of WT1 protein.
WT1 reduces malignancy of malignant mesothelioma cell lines and might be a new molecular target in mesothelioma therapy
WT1 overexpression indicates a poor prognosis in patients with some gynecological tumors, but more studies are needed to confirm these findings.
No increased frequencies were observed for WT1-specific T cells.
in vitro evidence to demonstrate that Wilms' tumor 1 (WT1) negatively regulates the expression of the atRA synthetic enzymes, ALDH1A1, ALDH1A2 and ALDH1A3, in the 293 cell line, leading to significant blockage of atRA production.
the results of the present study are consistent with the hypothesis that miR-590 may promote G401 cell proliferation via downregulation of it specific target gene, WT1 as miR-590 expression level increased in Wilms' tumor tissues compared with normal kidney tissues.
our data demonstrated that NR4A1 protein physically associates with the WT1 promoter, and enhanced WT1 promoter transactivation and knockdown of WT1 in MIN6 cells induced apoptosis. These findings suggest that NR4A1 protects pancreatic beta-cells against H2O2 mediated apoptosis by up-regulating WT1 expression.
Multiple studies provide evidence that WT1 plays a significant role in a variety of cancers occurring mainly in childhood and adolescence, but with involvement in some adult cancers. Also, Wt1 has a tumor suppressive function and oncogenic properties as well.
Study highlighted the importance of WT1 mutations in developmental renal disorders and showed that novel genetic technologies, particularly rapid sequencing techniques, have allowed the identification of far more WT1 mutations, relevant to clinical practice, and thus highlighting the range of WT1 disease and variable phenotype-genotype correlation.
Study reviews the dynamic expression pattern of WT1 gene during embryonic development and its many functions in the regulation of the expression of target genes acting in tissue development, growth, differentiation, and apoptosis. [review]
correlation between relapse and MRD(WT1) was stronger in blood than in bone marrow samples
WT1 interference with Wnt signaling represents an important mode of its action relevant to the suppression of tumor growth and guidance of development.
Sodium butyrate-induced hyperacetylation up-regulates WT1 expression in porcine kidney fibroblasts, suggesting the involvement of histone acetylation in the transcriptional modulation of WT1 in porcine kidney cells.
Results indicate that WT1 plays important roles in the development of porcine preimplantation embryos, but not in oocyte maturation.
WT1 is expressed in porcine fetal fibroblasts, but the levels of expression were much lower compared to porcine primary kidney fibroblasts and swine testis, and WT1 is essential for the maintenance of development and survival of porcine fetal fibroblasts
Study summarizes the different roles of WT1b gene in the embryonic zebrafish kidney and the adult kidney as well. [review]
While wt1a has a more fundamental and early role in pronephros development and is essential for the formation of glomerular structures, wt1b functions at later stages of nephrogenesis.
This gene encodes a transcription factor that contains four zinc-finger motifs at the C-terminus and a proline/glutamine-rich DNA-binding domain at the N-terminus. It has an essential role in the normal development of the urogenital system, and it is mutated in a small subset of patients with Wilm's tumors. This gene exhibits complex tissue-specific and polymorphic imprinting pattern, with biallelic, and monoallelic expression from the maternal and paternal alleles in different tissues. Multiple transcript variants have been described. In several variants, there is evidence for the use of a non-AUG (CUG) translation initiation site upstream of and in-frame with the first AUG. Authors of PMID:7926762 also provide evidence that WT1 mRNA undergoes RNA editing in human and rat, and that this process is tissue-restricted and developmentally regulated.
