Focal segmental glomerulosclerosis (FSGS) is a pathological lesion rather than a disease, with a diverse etiology. FSGS may result from genetic and non‑genetic factors. FSGS is considered a podocyte disease due to the fact that in the majority of patients with proven‑FSGS, the lesion results from defects in the podocyte structure or function. However, FSGS does not result exclusively from podocyte‑associated genes, however also from other genes including collagen IV‑associated genes. Patients who carry the collagen type IVA3 chain (COL4A3) or COL4A4 mutations usually exhibit Alport Syndrome (AS), thin basement membrane neuropathy or familial hematuria (FH)...

Background: To develop cancer antigen-targeted immunotherapeutic strategies for malignant pleural mesothelioma (MPM), we investigated the individual and coexpressions of the cancer-associated antigens mesothelin (MSLN), cancer antigen 125 (CA125), and Wilms tumor 1 (WT1) in both epithelioid and non-epithelioid MPM. Methods: All available hematoxylin and eosin-stained slides from patients who were diagnosed with MPM (1989-2010) were reviewed. We constructed tissue microarrays from 283 patients (epithelioid = 234; non-epithelioid = 49)...

The Wilms tumor protein 1 (WT1) has been implicated in the control of several genes in sexual development, but its function in gonad formation is still unclear. Here, we report that WT1 stimulates expression of Kdr, the gene encoding VEGF receptor 2, in murine embryonic gonads. We found that WT1 and KDR are co-expressed in Sertoli cells of the testes and somatic cells of embryonic ovaries. Vivo-morpholino-mediated WT1 knockdown decreased Kdr transcripts in cultured embryonic gonads at multiple developmental stages...

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 blast cells of vaccine-treated patients with myelodysplastic syndromes (MDS). Since then, data on WT1 peptide vaccine-treated patients with immunological and/or clinical response have been accumulated...

The Wilms' tumor 1 (WT1) gene is believed to act as a canonical tumor suppressor. However, it has also been reported to function as an oncogene. Germline WT1 deletion is associated with Wilms' tumor and exogenous WT1 cDNA introduction into cells induces the transcriptional suppression of its oncogenic target genes. In contrast, high WT1 expression is associated with poor prognosis in patients with various cancers. Why WT1 acts as a tumor suppressor under certain conditions, but as an oncogene under other conditions is unknown...

Previous work showed that the activation of protein kinase A (PKA) signaling promoted mitochondrial fusion and prevented podocyte apoptosis. The cAMP response element binding protein (CREB) is the main downstream transcription factor of PKA signaling. Herein, we show that the pKA-agonist pCPT-cAMP prevented the production of adriamycin (ADR)-induced reactive oxygen species and apoptosis in podocytes, which were inhibited by CREB RNAi. The activation of PKA enhanced mitochondrial function and prevented the ADR-induced decrease of mitochondrial respiratory chain complex I subunits, NADH-ubiquinone oxidoreductase complex (ND) 1/3/4 genes, and protein expression...

Wilms' tumor (WT) is the most frequent malignant renal tumor in children. The survival rate is lower in patients with recurrence, and the factors that influence relapse in WT are not fully understood. Loss of heterozygosity on chromosome 16q (LOH 16q) has been reported to be associated with the relapse in WT, but this remains controversial. We performed a meta-analysis to clarify this. PUBMED, EMBASE, and the Cochrane Library were searched up to March 17, 2017. Ten studies involving 3385 patients were ultimately included in the meta-analysis...

Triple negative breast cancer (TNBC) is highly aggressive and has a few therapeutic treatments, so new targeted therapy and biomarkers are required to provide alternative choices for treating TNBC patients. Recent studies showed that vasculogenic mimicry (VM), the formation of blood channels by aggressive cancer cells that mimic endothelial cells, is a factor contributing to poor prognosis in TNBC. Wilms' tumor 1 (WT1) gene has been found to be highly expressed in TNBC, and has 4 major distinct isoforms; isoform A (-17AA/-KTS; -/-), isoform B (+17AA/-KTS; +/-), isoform C (-17AA/+KTS; -/+) and isoform D (+17AA/+KTS; +/+)...

In many cancers, microRNA-193a (miR-193a) is a suppressor miRNA, but its underlying anti-oncogenic activity in breast cancer is not known. In this study, we found decreased miR-193a (specifically, miR-193a-5p) expression not only in breast cancer cell lines but also in breast cancer tissues as compared with the adjacent non-tumor tissues. Ectopic miR-193a overexpression inhibited the proliferation, colony formation, migration, and invasion of MDA-MB-231 and BT549 cells. miR-193a reduced Wilms' tumor 1 (WT1) expression and repressed luciferase reporter activity by binding WT1 coding region sequences; mutation of the predicted miR-193a binding site abolished this effect...

BACKGROUND: Cancer-related gene expression data mostly originate from unfractionated bulk samples, leading to "expression averaging" of heterogeneous populations. Multicolor flow cytometry (FCM) may distinguish heterogeneous populations based on the phenotypic characterization of single-cells, but is not applicable for RNA targets. Here, we evaluated the PrimeFlow™ RNA assay, a novel FCM-based assay designed to measure gene expressions, in two cancer entities with high and low RNA target levels...

The Wilms tumor suppressor gene (WT1) encodes an essential transcription factor regulating mammalian urogenital development. However, the function of WT1 in human endometrium is still unclear. The current study examined the involvement of WT1 in the regulation of IGF-binding protein-1 (IGFBP-1) and prolactin (PRL), which are specific markers of decidualization, in human endometrial stromal cells (ESCs) undergoing decidualization. ESCs isolated from proliferative-phase endometrium were incubated with cyclic adenosine monophosphate (cAMP) to induce decidualization...

Wilms' tumor suppressor 1 (WT1) plays an important role in cell proliferation and mesenchymal-epithelial balance in normal development and disease. Here, we show that following podocyte depletion in three experimental models, and in patients with focal segmental glomerulosclerosis (FSGS) and membranous nephropathy, WT1 increased significantly in cells of renin lineage (CoRL). In an animal model of FSGS in RenWt1(fl/fl) reporter mice with inducible deletion of WT1 in CoRL, CoRL proliferation and migration to the glomerulus was reduced, and glomerular disease was worse compared with wild-type mice...

BACKGROUND: Focal segmental glomerulosclerosis (FSGS) is considered a subset of the podocytopathies. The molecular pathogenesis of podocytopathy is still unknown. There has not been an experimental animal model of isolated podocytopathy induced by antibody in C57BL/6 strain, which is widely used as the genetic background. Nephrin is closely associated with the slit diaphragm of the glomerular podocyte, and has recently received attention as a potential therapeutic target. The function of nephrin, especially its role in FSGS development via podocytopathy, is being elucidated...

Pancreatic ductal adenocarcinoma (PDA) is characterized by a very poor prognosis, despite novel chemotherapeutic treatments. Moreover, the majority of PDA patients with complete surgical resection show recurrence within 5 years of resection. Therefore, new targeted cancer vaccines are urgently needed to extend PDA patient survival. The Wilms' tumor 1 (WT1) antigen was identified as an excellent antigen in a list of 75 tumor-associated antigens by a National Cancer Institute prioritization project based on several factors, such as therapeutic function...
