Sp1 is a critical regulator of the Wilms' tumor-1 gene.
We performed deletion analysis of WT1-reporter constructs containing up to 24 kilobases of 5'-flanking and first intron WT1 sequence in stably transfected cultured cells as an unbiased approach to identify cis elements critical for WT1 transcription. Although not a tissue-specific element, a proximate 9-base pair CTC repeat accounted for approximately 80% of WT1 transcription in this assay. Enh...
متن کاملIn silico screening of G-Quadruplex Structures in Wilms tumor 1 Gene Promoter
Introduction: X-ray diffraction studies have revealed that guanines in a DNA stands may be arranged in quartet and form a structure called G-quadruplexs. Bioinformatics studies suggested the formation of G-quadruplex structure in human crucial genes, including Wilms tumor 1 (WT1). The aim of this study was to in silico analysis of the guanine-rich sequence in the promoter region of the WT1 gene...
متن کاملSp1 binding is critical for promoter assembly and activation of the MCP-1 gene by tumor necrosis factor.
The monocyte chemoattractant protein-1 gene (MCP-1) is induced by the inflammatory cytokine tumor necrosis factor through the coordinate assembly of an NF-kappaB-dependent distal regulatory region and a proximal region that has been suggested to bind Sp1 as well as other factors. To provide a genetic correlation for Sp1 activity in this system, a cell line homozygous for a targeted truncation o...
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...
متن کاملThe E2F3-Oncomir-1 axis is activated in Wilms' tumor.
Oncomir-1 is an oncogenic cluster of microRNAs (miRNA) located on chromosome 13. Previous in vitro studies showed that it is transcriptionally regulated by the transcription factor E2F3. In this report, we combine expression profiling of both mRNA and miRNAs in Wilms' tumor (WT) samples to provide the first evidence that the E2F3-Oncomir-1 axis, previously identified in cell culture, is deregul...
