The major podocyte protein nephrin is transcriptionally activated by the Wilms' tumor suppressor WT1.
NPHS1 encodes the structural protein nephrin, which has a crucial role in the filtration barrier of the glomerular podocyte. Mutations or deregulation of NPHS1 are associated with a variety of renal diseases, including the Finnish type congenital nephrotic syndrome. This study analyzed a potential regulation of nephrin by the Wilms' tumor protein, Wt1. Using an inducible U2OS osteosarcoma cell ...
متن کاملThe tumor suppressor gene hypermethylated in cancer 1 is transcriptionally regulated by E2F1.
The Hypermethylated in Cancer 1 (HIC1) gene encodes a zinc finger transcriptional repressor that cooperates with p53 to suppress cancer development. We and others recently showed that HIC1 is a transcriptional target of p53. To identify additional transcriptional regulators of HIC1, we screened a set of transcription factors for regulation of a human HIC1 promoter reporter. We found that E2F1 s...

متن کاملMutations of the p53 tumor suppressor gene occur infrequently in Wilms' tumor.
Mutations of the p53 tumor suppressor gene occur frequently in a variety of adult-onset tumors, including colon, breast, lung, and brain, yet are infrequently identified in pediatric malignancies. Wilms' tumor, a common solid tumor of childhood, can be associated with mutations of the WT1 gene. Alterations of the p53 gene have been shown to modulate the ability of WT1 to transactivate its targe...
متن کاملThe Wilms' tumor 1 tumor suppressor gene represses transcription of the human telomerase reverse transcriptase gene.
Regulation of the human telomerase reverse transcriptase (hTERT) gene is the primary determinant for telomerase enzyme activity, which is found in tumor cells but is largely absent from normal somatic cells. Recent studies have shown that Myc protein can transcriptionally activate the hTERT gene. However, little is known about the repression mechanism of the hTERT gene and telomerase enzyme. He...
