  • Characterization of the 5′-Flanking Region of the rat TIS11 gene
    Molecular and Cellular Biochemistry, 2000
    Co-Authors: Tomiyasu Murata, Yoshiro Niimi, Norio Kaneda
    Abstract:

    To understand the mechanism underlying the transcriptional regulation of the immediate early gene TIS11, we characterized the 5′-Flanking Region of the rat TIS11 gene. When fused to the luciferase reporter gene, the 5.3-kb 5′-Flanking Region of the rat TIS11 gene exhibited functional promoter activity in pheochromocytoma PC12 and hepatoma H4IIE cells. 5′-Deletion analyses indicated that multiple negative and positive regulatory Regions were present in the 5′-Flanking Region, and that some of these Regions functioned in a cell type-specific manner. Promoter activity of the rat TIS11 gene was enhanced by phorbol 12-myristate 13-acetate (PMA) in both cell lines, and the PMA-responsiveness resided within the 5′-Flanking Region. The induction of promoter activity by PMA was completely blocked by GF109203X or PD98059, inhibitors of protein kinase C and mitogen-activated protein (MAP) kinase kinase, respectively. These results suggested that induction of the rat TIS11 promoter by PMA is mediated by activation of the protein kinase C/MAP kinase cascade.

  • Binding of kidney nuclear proteins to the 5′-Flanking Region of the rat gene for Ca2+-binding protein regucalcin: Involvement of Ca2+/calmodulin signaling
    Molecular and Cellular Biochemistry, 1999
    Co-Authors: Tomiyasu Murata, Masayoshi Yamaguchi
    Abstract:

    Ca2+-binding protein regucalcin is expressed in the kidney cortex of rats, as assayed by Northern blot analysis. The existence of kidney nuclear factor which binds to the 5'-Flanking Region of the rat regucalcin gene was investigated. When nuclear extracts obtained from the kidney cortex of rats were used in gel mobility-shift assays, two protein-DNA complexes were uniquely formed with the DNA fragment containing the 5'-Flanking Region of the rat regucalcin gene. Competition gel shift experiments indicated the specific binding Region of kidney cortex nuclear proteins in the 5′-Flanking Region of the rat regucalcin gene. The two nuclear protein-DNA complexes were formed with the same mobility in rat kidney cortex and liver, which possess detectable amounts of regucalcin mRNA in Northern blot analysis. The binding activities of nuclear factors from kidney cortex to the 5′-Flanking Region of the rat regucalcin gene were inhibited by a single intraperitoneal administration of trifluoperazine, an antagonist of calmodulin, to rats. The present study demonstrates that kidney cortex nuclear proteins specifically bind to the 5′-Flanking Region of the rat regucalcin gene, and that the binding activity may be partly mediated through the Ca2+/calmodulin-dependent process.

  • Cloning of the 5′-Flanking Region of the murine bone morphogenetic protein-7 gene
    Molecular and Cellular Biochemistry, 2002
    Co-Authors: Matthias Simon, Denis Feliers, Mazen Arar, Basant Bhandari, Hanna E. Abboud
    Abstract:

    BMP-7, a member of the bone morphogenetic protein subfamily of the TGFβ-superfamily is highly expressed in the murine kidney. BMP-7 is involved in fetal nephron development and mesenchymal to epithelial cell differentiation. Constitutive BMP-7 expression is found in tubular and glomerular epithelial cells of the adult kidney. BMP-7 may play a role in physiology and pathophysiology of the adult kidney since BMP-7 gene expression in acute renal ischemia is diminished and injection of recombinant BMP-7 into rats with ischemic acute renal failure preserves renal function. In order to investigate the transcriptional regulation of BMP-7, this study was undertaken to clone and characterize the promoter of the murine BMP-7 gene. A 1394 bp sequence of the 5′-Flanking Region of the BMP-7 gene was isolated and subcloned. No TATA and CAAT box consensus motifs could be identified as shown for promoters of other BMPs. Using in vitro transfection assays, the 5′-Flanking Region revealed moderate to strong basal promoter activity. PMA increased basal BMP-7 promoter activity. Thus BMP-7 gene transcription might involve at least in part a PKC-dependent pathway. The cloning of a 5′-Flanking Region of the BMP-7 gene should provide a useful tool for future studies on the transcriptional regulation of BMP-7 gene expression.
