Structure and mapping of the fosB gene. FosB downregulates the activity of the fosB promoter.

ABSTRACT: We have determined the genomic structure of the fosB gene and shown that it consists of 4 exons and 3 introns at positions also found in the c-fos gene. By deletion analysis we have characterized a region upstream of the TATA box which is the promoter region of the gene. Several consensus sequences have been identified, including an SRE and AP-1 binding site whose relative positions are identical to those in the 5' upstream region of the c-fos gene. We have also shown that FosB and c-Fos can downregulate the activity of the fosB promoter to a similar extent. The fosB gene is located in the [A1-B1] region of mouse chromosome 7.

DNA methylation directly downregulates human cathelicidin antimicrobial peptide gene (CAMP) promoter activity.

Project description:LL-37, the active product of human cathelicidin antimicrobial peptide (CAMP) has a broad spectrum of antibacterial activity. LL-37 also has important physiological functions in immune regulation, angiogenesis and in modulating apoptosis. The roles of LL-37 in oral squamous cell carcinoma (OSCC) are still not clear. The correlation between DNA methylation and human CAMP expression is also unknown. Here human CAMP/LL-37 expression was assessed by immunohistochemistry in normal and OSCC tissues. The results indicated that low expression of CAMP/LL-37 correlated with histological differentiation and lymph node metastasis and also promoted tumor progression. A cell-specific methylation pattern in the promoter region of human CAMP was detected. Treatment with 5-aza-2'-deoxycytidine, a DNA demethylation reagent can increase human CAMP expression in epithelial cancer cells. The reporter assay showed that unmethylated human CAMP promoter activity was significantly higher than methylated promoter activity. Taken together, these results suggested that human CAMP/LL-37 might act as a tumor-suppressor in OSCC and DNA methylation might play roles during carcinogenesis via directly downregulating human CAMP promoter activity.

Tumor necrosis factor-{alpha} downregulates intestinal NHE8 expression by reducing basal promoter activity.

Project description:NHE8 transporter is a member of the sodium/hydrogen exchanger (NHE) family. This transporter protein is expressed at the apical membrane of epithelial cells of kidney and intestine and contributes to vectorial Na(+) transport in both tissues. Although NaCl absorption has been shown to be reduced in diarrhea associated with colitis and enteritis, little is known about the role of Na(+)/H(+) exchange and the involvement of NHE isoforms in the pathogenesis of inflammatory disorders and the mechanism of inflammation-associated diarrhea. This study investigated the role of NHE8 in the setting of inflammatory states. Jejunal mucosa was harvested from trinitrobenzene sulfonic acid (TNBS) colitis rats or lipopolysaccharide (LPS) rats for RNA extraction and brush-border membrane protein purification. The human NHE8 gene promoter was cloned from human genomic DNA and characterized in Caco-2 cells. The promoter was further used to study the mechanisms of TNF-alpha-mediated NHE8 expression downregulation in Caco-2 cells. Results from Western blot and real-time PCR indicated that NHE8 protein and mRNA were significantly reduced in TNBS rats and LPS rats. In Caco-2 cells, TNF-alpha produces similar reduction levels in the endogenous NHE8 mRNA expression observed in our in vivo studies. The downregulation of NHE8 expression mediated by TNF-alpha could be blocked by transcription inhibitor actinomycin D, suggesting the involvement of transcriptional regulation. Further studies indicated that the human NHE8 gene transcription could be activated by Sp3 transcriptional factor, and TNF-alpha inhibits human NHE8 expression by reducing Sp3 interaction at the minimal promoter region of the human NHE8 gene. In conclusion, our studies suggest that TNF-alpha decreases NHE8 expression in inflammation induced by TNBS and LPS, which may contribute to the diarrhea associated with inflammation.

Genome-wide mapping of autonomous promoter activity in human cells.

Project description:Previous methods to systematically characterize sequence-intrinsic activity of promoters have been limited by relatively low throughput and the length of the sequences that could be tested. Here we present 'survey of regulatory elements' (SuRE), a method that assays more than 108 DNA fragments, each 0.2-2 kb in size, for their ability to drive transcription autonomously. In SuRE, a plasmid library of random genomic fragments upstream of a 20-bp barcode is constructed, and decoded by paired-end sequencing. This library is used to transfect cells, and barcodes in transcribed RNA are quantified by high-throughput sequencing. When applied to the human genome, we achieve 55-fold genome coverage, allowing us to map autonomous promoter activity genome-wide in K562 cells. By computational modeling we delineate subregions within promoters that are relevant for their activity. We show that antisense promoter transcription is generally dependent on the sense core promoter sequences, and that most enhancers and several families of repetitive elements act as autonomous transcription initiation sites.

IL-6 downregulates transcription of NTPDase2 via specific promoter elements.

Project description:Bile ductular proliferation is markedly upregulated in biliary fibrosis and cirrhosis. However, the mechanisms regulating this upregulation in bile ductular proliferation have not been defined. Recently, we demonstrated that expression of the ectonucleotidase nucleoside triphosphate diphosphohydrolase-2 (NTPDase2/Entpd2) by portal fibroblasts (PF) is a critical regulator of bile ductular proliferation. Since interleukin 6 (IL-6) is markedly upregulated in biliary cirrhosis, our aims were to determine the role and mechanism of IL-6 in the regulation of NTPDase2 by PF. We found that IL-6 downregulated NTPDase2 protein expression in a concentration-dependent and time-dependent fashion but did not alter PF alpha-smooth muscle actin expression. IL-6 markedly downregulated NTPDase2 mRNA expression. Expression of the IL-6 receptor gp130 but not the IL-6 receptor gp80 was detected in PF. Two transcription start sites were identified in rat Entpd2 by the method of RNA ligase-mediated rapid amplification of 5' cDNA ends. The minimal promoter construct, but not shorter constructs, was downregulated by IL-6. Three putative IL-6 response elements were identified in silico and mutated. Mutation of all three response elements, but not fewer elements, completely abolished the IL-6 response. Thus IL-6 transcriptionally downregulates NTPDase2 expression by PF via actions at specific promoter elements independently of myofibroblastic differentiation. This effect may represent a novel signaling pathway by which bile ductular proliferation is dysregulated in biliary cirrhosis and thus provides a potential therapeutic approach for the regulation of bile ductular growth.

Rat gene 33: analysis of its structure, messenger RNA and basal promoter activity.

Project description:Several overlapping cDNA and genomic DNA clones corresponding to mRNA g33 and gene 33, respectively, were isolated and characterized. The mRNA g33 molecule is 2971 nt in length, exclusive of a poly(A+) tail, and encodes a putative 459 amino acid protein (49,946 daltons). The 13.2 kbp gene consists of four exons, three introns, and has two initiation sites located 27 and 30 bp downstream from a TATA box. Transfection of H4IIE cells with a fusion gene 33 (-1900 to +32)/luciferase construct (pSL330A) gave rise to readily detectable luciferase activity. In addition, primer extension analysis of the gene 33/luciferase mRNA transcribed in these experiments showed that transcription initiates in the gene 33 DNA at two sites consistent with those found in vivo. Analysis of the effect of 5' deletions on basal promoter activity showed that, in relation to the promoter activity of pSL330A, approximately 40% of the activity is lost between -1643 and -1050, another approximately 40% between -550 and -475, and deletion to -55 causes a total loss of detectable luciferase activity.

The RAD17 Promoter Sequence Contains a Potential Tail-Dependent G-Quadruplex That Downregulates Gene Expression upon Oxidative Modification.

Project description:Our laboratory has recently proposed that the oxidation of guanine (G) to 8-oxo-7,8-dihydroguanine (OG) in G-rich promoter regions of DNA repair genes can serve as a regulatory mechanism of gene transcription. These regions also have the potential to fold into G-quadruplexes (G4). The human RAD17 promoter sequence has such a region in the template strand of the gene. In this work, the potential G-quadruplex sequence (PQS) of the RAD17 gene promoter was analyzed in different sequence contexts. With two extra nucleotides of the native sequence on either side of the G4, the structure was found to fold into a hybrid-like G4, similar to the hybrid-1 fold that the human telomere sequence can adopt. With only one nucleotide on either side of the PQS, the topology of the structure was observed to be mixed, and without extra nucleotides on the ends, the sequence adopted a parallel fold. Next, the sequence was studied with synthetic incorporation of the oxidative modification OG into specific sites and installed into the promoter of plasmids with a luciferase gene. These plasmids were transfected into a human cell line to observe the effect of the G4s on transcription. The RAD17 PQS was found to decrease luciferase expression with the presence of OG that is consistent with RAD17 expression under oxidative stress. This serves as an example of how oxidative modification could affect transcription in the context of a G4.

Transcription initiation mapping in 31 bovine tissues reveals complex promoter activity, pervasive transcription, and tissue-specific promoter usage.

Project description:Characterizing transcription start sites is essential for understanding the regulatory mechanisms that control gene expression. Recently, a new bovine genome assembly (ARS-UCD1.2) with high continuity, accuracy, and completeness was released; however, the functional annotation of the bovine genome lacks precise transcription start sites and contains a low number of transcripts in comparison to human and mouse. By using the RAMPAGE approach, this study identified transcription start sites at high resolution in a large collection of bovine tissues. We found several known and novel transcription start sites attributed to promoters of protein-coding and lncRNA genes that were validated through experimental and in silico evidence. With these findings, the annotation of transcription start sites in cattle reached a level comparable to the mouse and human genome annotations. In addition, we identified and characterized transcription start sites for antisense transcripts derived from bidirectional promoters, potential lncRNAs, mRNAs, and pre-miRNAs. We also analyzed the quantitative aspects of RAMPAGE to produce a promoter activity atlas, reaching highly reproducible results comparable to traditional RNA-seq. Coexpression networks revealed considerable use of tissue-specific promoters, especially between brain and testicle, which expressed several genes in common from alternate loci. Furthermore, regions surrounding coexpressed modules were enriched in binding factor motifs representative of each tissue. The comprehensive annotation of promoters in such a large collection of tissues will substantially contribute to our understanding of gene expression in cattle and other mammalian species, shortening the gap between genotypes and phenotypes.

DNA methylation of the PLIN1 promoter downregulates expression in chicken lines.

Project description:Evidence suggests that Perilipin-1 (PLIN1) is subject to functional regulation by epigenetic modifications in women with obesity. However, whether chicken PLIN1 expression is regulated by DNA methylation is unknown. Here, Sequenom MassARRAY and real-time polymerase chain reaction (PCR) were conducted to analyze the promoter methylation status and expression of the PLIN1 gene in Northeast Agricultural University broiler lines divergently selected for abdominal fat content. We found that chicken PLIN1 expression was significantly higher in adipose tissue of fat-line broilers than in lean lines at 1-7 weeks of age, and was significantly positively correlated with abdominal fat percentage (AFP) in chicken adipose development (Pearson's r=0.627 , P<0.001 ). The region analyzed for DNA methylation was from -12 to -520 ?bp upstream of the translation start codon ATG, and had five CpG sites, where only the DNA methylation levels of CpG5 located at position -490 ?bp were significantly higher in lean compared to fat chickens at 5 and 6 weeks ( P<0.05 ) and were significantly negatively correlated with PLIN1 mRNA levels and AFP ( P<0.05 ). These results shed new light on the regulation of hypertrophic growth in chicken adipose development.

Structure and promoter activity of the gene for the erythroid transcription factor GATA-1.

Project description:We have cloned the gene for the chicken erythroid transcription factor GATA-1 (formerly Eryf1, NF-E1, or GF-1). The gene is composed of six exons, two of which encode the two finger domains of the protein. Transcription of GATA-1 in chicken embryonic erythroid cells initiates from multiple sites clustered approximately 200 base pairs upstream from the start of protein-coding sequence. A number of sequence motifs for known DNA-binding proteins are found to be protected in DNase I-footprinting experiments by either erythroid or brain nuclear extracts or by both. Notably, a cluster of three GATA-1 sites is protected by the erythroid extract, as well as by purified GATA-1. We find that the upstream region of the gene functions as a powerful promoter when transfected into embryonic erythroid cells. In primary chicken embryo fibroblasts the promoter exhibits lower activity, which is increased when the cells are cotransfected with a second plasmid expressing the GATA-1 cDNA. The results suggest that GATA-1 protein plays an autoregulatory role in its own expression.
