Neuron-restrictive silencer factor has been shown to bind to the NRSE sequence within the MOR gene and play important roles in modulating the expression of the MOR gene. 8,18,19,47 Next, we investigated the expression of NRSF in the ipsilateral spinal dorsal horn or L2-4 DRG after sarcoma cell inoculation at both transcriptional and translational levels. NRSE-like sequences are present in the human CYP11B2 (hCYP11B2) and CYP11B1 (hCYP11B1) genes. A homology search for NRSE-like sequences identified NRSE-like sequences within the genomic sequence corresponding to intron 8 and exon 9 of the human genes but not in those of other species ( Supplemental Table 2 ). 2006-07-09 · Using comparative sequence analysis, here we report the identification of 895 sites (NRSE) as the putative targets of REST. A set of the identified NRSE sites is present in the vicinity of the miRNA genes that are specifically expressed in brain-related tissues, suggesting the transcriptional regulation of these miRNAs by REST. RNA-containing NRSE sequence forms double-stranded Neuronal Lineage Induction by the NRSE dsRNA RNA (dsRNA) in lengths of about 20 bp, and that the To determine the function of the NRSE dsRNA, we ex- NRSE dsRNA activates expression of NRSE / RE1 -con- pressed them in HCN-A94 cells.

2015-02-11 · The neuron-restrictive silencer factor (NRSF) binds with the neuron-restrictive silencer element (NRSE), thereby suppressing the transcription of NRSE-containing genes. In this study, we show that the NRSE sequence of the VGF gene critically regulates the repression of VGF expression in NMB cells. (A) The putative Sp family binding site and NRSE sequence among three species, mouse, human and rat is located from −9 to +20 in the MOR gene and have highly homologous (∗) sequence to the consensus Sp family binding site and NRSE DNA element. NRSE engineered superior cervical ganglion (SCG)10 promoter activities. The NRSE sequence consisting of 5′-TTCAGCACCACGGAGAGTGCC-3′ from the SCG10 gene 8 was used in this study Stéphanie De Gois, Leı̈la Houhou, Yoshio Oda, Marilys Corbex, Fabrice Pajak, Etienne Thévenot, Guilan Vodjdani, Jacques Mallet, Sylvie Berrard 2007-02-02 · The computer search revealed that an NRSE-like sequence was located ∼2 kb upstream of exon 2 of the HCN4 gene (Fig.

As shown in Fig. 4B, each reporter containing the intact NRSE sequence (left panel) exhibited less luciferase activity than those with the mutated NRSE sequences (right panel). 2004-05-01 In addition to the influence on the ANP gene, the NRSE sequence regulates other cardiac embryonic genes, such as BNP, skeletal α-actin, and Na, K – ATPase α3 subunit. Hence, the regulatory activity of both NRSE and NRSF in mammals prevents not only neural dysfunctions, but also physiological and phenotypical abnormalities in other non-neuronal regions of the body.

Discovering the molecular mechanisms that regulate neuron-specific gene expression remains a central challenge for CNS research. Here, we report that small, noncoding double-stranded (ds) RNAs play a critical role in mediating neuronal differentiation. The sequence defined by this dsRNA is NRSE/RE1, which is recognized by NRSF/REST, known primarily as a negative transcriptional regulator that

So, a model is emerging whereby cells that are to become neurons activate the transcription of genes that contain the NRSE/RE1 sequence.

The following figure shows an NRSE system. In an NRSE measurement system, all measurements are still made with respect to a single-node analog input Jan 11, 2016 for a human, a genomic reference sequence does not contain any useful information (a coding DNA reference sequence does); a gene can be Jan 10, 2017 These NRSE-ODNs as well as random-sequence control ODNs entered neurons and neuronal nuclei (Figure 2f), and acted as decoys, binding This upstream sequence was used to control the expression of a reporter gene in The ChAT NRSE was inactive in neuronal cells but repressed expression in to function as a nuclear receptor that interacts with NRSF, a silencer protein that binds the DNA sequence element NRSE (neuron-restrictive silencer element). av M Larsson — NRSE: transposoner som cis-regulatoriska element kan påverka neurologisk funktion. Ett exempel Finishing the euchromatic sequence of the human genome.

NRSF, a zinc finger transcription factor that binds to the 21-bp recognition sequence NRSE, is a transcriptional repressor of multiple neuronal genes and is normally down-regulated upon neuronal differentiation (44. Su X. To address this, we investigated the effect of REST/NRSF and REST4 on the activity-dependent activation of BDNF gene promoter I (BDNFp-I) using cultured rat cortical neurons. REST/NRSF markedly repressed the transcriptional activation of BDNFp-I, whereas the effect of REST4 was weak, depending upon the NRSE/RE1 sequence.

In view of the function of NRSF–NRSE system and the distribution proﬁle of CART, we postulate that NRSF may play a regulatory role in the speciﬁc expression of CART gene.

NRSE-like sequences are found in intron 8 and exon 9 of the human CYP11B2 and CYP11B1 genes. There are no NRSE-like sequences in the rat CYP11B2 and CYP11B1 genes. Moreover, the human and rat CACNA1H genes, which encode the α-subunit of Cav3.2, contain a functional NRSE sequence .

A silencer is a sequence-specific element that induces a negative effect on the transcription of its particular gene. There are many positions in which a silencer element can be located in DNA. The most common position is found upstream of the target gene where it can help repress the transcription of the gene.

A set of the identified NRSE sites is present in the vicinity of the miRNA genes that are specifically expressed in brain-related tissues, suggesting the transcriptional regulation of these miRNAs by REST. RNA-containing NRSE sequence forms double-stranded Neuronal Lineage Induction by the NRSE dsRNA RNA (dsRNA) in lengths of about 20 bp, and that the To determine the function of the NRSE dsRNA, we ex- NRSE dsRNA activates expression of NRSE / RE1 -con- pressed them in HCN-A94 cells. So, a model is emerging whereby cells that are to become neurons activate the transcription of genes that contain the NRSE/RE1 sequence. These cells might then generate non-coding NRSE/RE1 dsRNAs Schoenherr and Anderson (1995) showed that NRSF bound the NRSE DNA sequence in the 5-prime region of SCG10.

This upstream sequence was used to control the expression of a reporter gene in The ChAT NRSE was inactive in neuronal cells but repressed expression in

To negative transcriptional regulator that restricts neu-identify possible target nucleic acids, public database In RNA immunoprecipitation and gel-shift assays, NRSF specifically interacted with the NRSE sequence of MOR mRNA. When MOR and NRSF genes were coexpressed, the specific ligand-binding activity of MOR was increased in neuroblastoma NMB cells, but decreased in PC12 cells result from its localization.

NRSE sequences were effective in restricting expression of bipartite Gal4-based 'driver' transgenes within the context of an enhancer trap and when associated with a defined promoter and enhancer. Repressor element-1 silencing transcription factor (REST) is a transcriptional repressor of neuron-specific genes that binds to a conserved DNA element, the neuron restrictive silencer element (NRSE/RE1).
