The WT1 gene is a tumor-suppressor gene that was isolated as a gene responsible for Wilms' tumor, a childhood kidney neoplasm. We have previously reported that the WT1 gene is strongly expressed in leukemia cells with an increase in its expression levels at relapse and an inverse correlation between its expression levels and prognosis, thus making it a novel tumor marker for leukemic blast cell...
The Wilms' tumor gene WT1 is a recessive oncogene that encodes a putative transcription factor implicated in nephrogenesis during kidney development. In this report we analyze expression of WT1 in the murine urogenital system. WT1 is expressed in non-germ-cell components of the testis and ovaries in both young and adult mice. In situ mRNA hybridization studies demonstrate that WT1 is expressed ...
Wt1 is a tumour suppressor gene, mutation of which is a cause of Wilms' tumour, a childhood renal nephroblastoma. Wt1 is expressed in a rich pattern during renal development suggesting that it acts at three stages: determination of the kidney area, the differentiation of nephrons and maturation of glomeruli. Wt1-/- mice confirm that Wt1 is essential for the inception of kidney development; cell...
Wilms' tumor gene 1 (WT1) plays complex roles in tumorigenesis, acting as tumor suppressor gene or an oncogene depending on the cellular context. A high WT1 expression level was described in various types of human bone and soft-tissue sarcomas, including osteosarcoma (OS), but its function in carcinogenesis is not yet well understood. This study investigated WT1 both in human OS tissues and in ...
Wilms tumor gene protein 1 is associated with ovarian cancer metastasis and modulates cell invasion.
BACKGROUND Although metastatic disease is the primary cause of death from epithelial ovarian carcinoma, to the authors' knowledge the cellular mechanisms that regulate intraperitoneal metastasis are largely unknown. Metastasizing ovarian carcinoma cells encounter a collagen-rich microenvironment because the submesothelial matrix is comprised mainly of interstitial collagens Types I and III. M...
The Wilms' tumour suppressor protein WT1 plays a central role in the development of the kidney and also other organs. WT1 can act as a transcription factor with highly context-specific activator and repressor functions. We previously identified Brain Acid Soluble Protein 1 (BASP1) as a transcriptional cosuppressor that can block the transcriptional activation function of WT1. WT1 and BASP1 are ...
Mutations of the Wilms' tumour-1 (WT1) gene in humans can lead to childhood kidney cancer, life-threatening glomerular nephropathy and gonadal dysgenesis. The WT1 protein is normally expressed in the developing genitourinary tract, heart, spleen and adrenal glands and is crucial for their development, however it's function at the molecular level is yet to be fully understood. The protein is pre...
The product of the Wilms' tumor gene, WT1, is essential for male sex determination and differentiation in mammals. In addition to causing Wilms' tumor, mutations in WT1 often cause two distinct but overlapping urogenital defects in men, Denys-Drash syndrome and Frasier syndrome. In this study we investigated the regulation of the sex determination gene SRY by WT1. Our results showed that WT1 up...
The Wilms' tumour gene, WT1, encodes a zinc-finger transcription factor that is inactivated in a subset of Wilms' tumours. Mutation analysis in human patients and genetic experiments in mice have revealed that WT1 has a role much wider than just tumour suppression. Alternative splicing, RNA editing, and the use of alternative translation initiation sites generate a multitude of isoforms, which ...
Wilms' Tumour 1 gene (WT1) is required for the correct development of the urogenital system. To examine its regulation and expression, we created several transgenic mouse lines containing a beta-galactosidase reporter driven by the human WT1 promoter. A 5 kb promoter weakly recapitulated a subset of the endogenous Wt1 expression pattern. In contrast, 470 and 280 kb YAC transgenes reproduced the...
