WT1 is a tumor suppressor gene with a key role in urogenital development and the pathogenesis of Wilms' tumor. Two alternative splice sites in the WT1 transcript allow the gene to encode four proteins. These carry four Krüppel-type zinc fingers and to date have primarily been implicated in transcriptional control of genes involved in growth regulation.(More)
The Wilms' tumour suppressor gene (WT1) encodes a protein(s) with 4 zinc fingers that is essential for the development of the genitourinary system. A considerable body of evidence exists to support the idea that WT1 binds DNA and functions as a transcription factor. However, we have shown recently by confocal microscopy and immunoprecipitation studies that(More)
As health care systems worldwide struggle with rising costs, a consensus is emerging to refocus reform efforts on value, as determined by the evaluation of patient outcomes relative to costs. One method of using outcome data to improve health care value is the disease registry. An international study of thirteen registries in five countries (Australia,(More)
WT1 is essential for normal kidney development, and genetic alterations are associated with Wilms' tumor, Denys Drash (DDS), and Frasier syndromes. Although generally considered a transcription factor this study has revealed that WT1 interacts with an essential splicing factor, U2AF65, and associates with the splicing machinery. WT1 is alternatively spliced(More)
The Wilms tumor suppressor gene WT1 is implicated in the ontogeny of genito-urinary abnormalities, including Denys-Drash syndrome and Wilms tumor of the kidney. WT1 encodes Kruppel-type zinc finger proteins that can regulate the expression of several growth-related genes, apparently by binding to specific DNA sites located within 5' untranslated leader(More)
Phosphorylation of the alpha-1 subunit of rat Na+,K(+)-ATPase by protein kinase C has been shown previously to decrease the activity of the enzyme in vitro. We have now undertaken an investigation of the mechanism by which this inhibition occurs. Analysis of the phosphorylation of recombinant glutathione S-transferase fusion proteins containing putative(More)
We have previously demonstrated that leukotriene B4 (LTB4) induces in vitro a transient state of hyperadhesiveness in cultured human umbilical vein endothelial cells (HUVEC) for neutrophils (PMN). The magnitude of this response is intermediate of that conferred by thrombin and by platelet-activating factor (PAF). This report shows that the LTB4 response was(More)
During the peri- and early postnatal period, nephrogenesis is completed and kidney growth is accomplished both by cellular proliferation and enlargement. The number of nephrons in a given species is predetermined, whereas cellular growth can be influenced by environmental factors in an age-dependent manner. Unilateral nephrectomy or a high-protein diet(More)
Neurokinin A, a member of the tachykinin family of neuropeptides, has been identified as a mitogen for cultured smooth muscle cells. Tachykinin-induced DNA synthesis has previously been shown to be mediated by a receptor-specific mechanism and to correlate with accumulation of phosphatidylinositol 4,5-bisphosphate breakdown products. In the present(More)
