We found that the mouse Na v 1.8 gene contains two putative conserved NRSE sites, a forward-oriented sequence within the 5′-untranslated region (NRSE-1) and a reverse-oriented sequence within intron 10 (NRSE-2) (Fig. 1 B, C). To better restrict transgene expression to the nervous system in zebrafish larvae, we have used DNA sequences derived from the neuron-restrictive silencing element (NRSE). We find that one such sequence, REx2, when used in conjunction with several basal promoters, robustly suppresses transgene expression in non-neuronal tissues. The sequence analysis of HCN4 gene revealed the presence of a conserved NRSE motif, which is known to bind the transcriptional factor neuron-restrictive silencing factor (NRSF). A promoter analysis of HCN4 with rat cardiac myocytes identified the region inducing a basal transcriptional activity. The RE1 consensus sequence used in this study is degenerate, allowing a total of 4,096 permutations.

For optimal silencing of L1 gene expression by the NRSE-binding factor RE-1–silencing transcription factor (REST)/NRSF, both the NRSE and sequences in the first intron were required. To better restrict transgene expression to the nervous system in zebrafish larvae, we have used DNA sequences derived from the neuron-restrictive silencing element (NRSE). We find that one such sequence, REx2, when used in conjunction with several basal promoters, robustly suppresses transgene expression in non-neuronal tissues. 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). Interestingly, increased REST activity is found in several neurological diseases like Huntington's disease and cerebral ischemia. The NRSF/REST sequence-tag distribution centers directly over the only canonical NRSE motif in a 4-kb region, which is located in the open reading frame of the NEUROD1 gene.

2). Additionofonemorecopyofthe 2000-09-01 In the NIH3T3 cell line, the RE-1/NRSE sequence leads to repression of reporter-gene activity, whereas introduction of exogenous REST4 leads to de-repression. These data indicate that REST4 does not act as a transcriptional repressor.

2000-07-14 · The ∼21 base pair RE-1/NRSE sequence has been found in a number of neuron specific genes including the type II sodium channel , the SCG10 gene , synapsin I , NMDA receptor , and the cholinergic gene locus to name but a few.

REST/NRSF markedly repressed the transcriptional activation of BDNFp-I, whereas the effect of REST4 was weak, depending upon the NRSE/RE1 sequence. NRSE sequence in the HCN1 gene and the structure of the NRSF gene are conserved in humans, mice, and rats [8], as shown in Figure 1. FIGURE 1: HCN1 Gene Contains a Conserved NRSE HCN1 Gene Contains a Conserved NRSE (McClelland, et al., 2008) Aside from the NRSE consensus sequence (the series of nucleotides most frequently found at NRSE 3700J *** Recommended to Fulfill Tier I Jr. Comp NRSE 3700J*** Recommended to Fulfill Tier I Jr. Comp NRSE 4741**** 2nd School Nurse Course - must be taken in sequence *NRSE 4600, Nursing Excellence – contact your advisor via email to request permission to be added to the course at least 5 weeks prior to start date. In addition to the influence on the ANP gene, the NRSE sequence regulates other cardiac embryonic genes, such as brain natriuretic peptide 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. The silencer activity of this region is mediated solely by a repressor element 1 or neuron-restrictive silencer element (RE1/NRSE).

Both CRH and the urocortins interact A, the NRSE sequence of the mouse MOR is very similar to a consensus NRSE, and it is highly conserved among at least three species, mouse, rat, and human. The NRSE is located from –12 to +9 on the MOR promoter and contains a translation start site (ATG). In addition to the influence on the ANP gene, the NRSE sequence regulates other cardiac embryonic genes, such as brain natriuretic peptide BNP, skeletal α-actin, and Na, K – ATPase α3 subunit.

Interestingly, increased REST activity is found in several neurological diseases like Huntington's disease and cerebral ischemia. The NRSF/REST sequence-tag distribution centers directly over the only canonical NRSE motif in a 4-kb region, which is located in the open reading frame of the NEUROD1 gene. This site was called a ChIPSeq peak by the locator algorithm [open source available at ( 14 )]. The consensus sequence of the Xenopus NRSE varies slightly from that of human.

sensus sequence of the known neuronal-restrictive silencing element (NRSE). We report here that this KCC2 element binds to nuclear proteins and inhibits the transcription of a reporter gene in C17 nonneuronal cells. METHODS Genomic library A Lamda FIXII mouse genomic library (Stratagene, La Jolla, CA) The identification of a common cis -acting silencer element, a neuron-restrictive silencer element (NRSE), in multiple neuron-specific genes, together with the finding that zinc finger transcription factor REST/NRSF/XBR could confer NRSE-mediated silencing in non-neuronal cells, suggested that REST/NRSF/XBR is a master negative regulator of neurogenesis. NRSE sequence in the HCN1 gene and the structure of the NRSF gene are conserved in humans, mice, and rats [8], as shown in Figure 1.

canonical RE1/NRSE sites, which have a variable linker between the two half-site RE1s/NRSEs,7 while a third type features half-site RE1/NRSE with only one-half of the canonical RE1/NRSE.7 Of note, variations of the RE1/NRSE sequence are associated with modulation of REST/NRSF affinity to the respective DNA site, allowing some RE1/NRSE sites

In this study, we identiﬁed a conserved NRSE sequence in silencing element (RE-1/NRSE) sequence. Recently, a family of CRH-related peptides, termed the urocortins, has been identiﬁed.

Twenty-two more genes, 17 of which are expressed mainly in neurons, were found to contain NRSE-like sequences. Mar 24, 1997 NRSE is a regulatory sequence that is present in several neuronal genes (8) and that was, up to now, thought to silence neuronal gene The human AVP NRSE-like motif. a, the human AVP promoter is shown in the center, aligned to the NRSE consensus sequence (12) above, and a motif from the sequence.

This factor is not expressed in insulin-secreting and neuron-like cells. NRSE is a regulator y sequence that is present in several neuronal genes (8) and that was, up to now, thought to silence neuronal gene transcription in nonneuronal cells (6, 7, 9 –14). Discovering the molecular mechanisms that regulate neuron-specific gene expression remains a central challenge for CNS research.
