Poly C Binding Protein 2 dependent nuclear retention of the utrophin-A mRNA in C2C12 cells.

Upregulation of utrophin, the autosomal homologue of dystrophin, can compensate dystrophin deficiency in Duchenne Muscular Dystrophy (DMD) although the therapeutic success is yet to be achieved. The present study has identified Poly (C) binding protein 2 (PCBP2) as a post-transcriptional suppresser for the expression of utrophin-A, the muscle-specific utrophin isoform. This study confirms nuclear retention of utrophin-A mRNA in C2C12 cells, which is mediated by PCBP2.

Repression-free utrophin-A 5'UTR variants.

Mutation in the dystrophin gene results Duchenne Muscular Dystrophy (DMD), an X-linked fatal neuromuscular disorder. Dystrophin deficiency can be compensated by upregulation of utrophin, an autosomal homologue of dystrophin. But the expression of utrophin in adults is restricted to myotendinous and neuromuscular junctions.

Genomic and Proteomic Characterizations of , a Novel Lytic Phage Infecting Multidrug-Resistant spp. and C.

Shigellosis is a public health threat in developed as well as developing countries like "India." While antibiotic therapy is the mainstay of treatment for shigellosis, current emergence of multidrug-resistant strains of spp. has posed the problem more challenging.

Cis-Acting Sequence Elements and Upstream Open Reading Frame in Mouse Utrophin-A 5'-UTR Repress Cap-Dependent Translation.

Utrophin, the autosomal homologue of dystrophin can functionally compensate for dystrophin deficiency. Utrophin upregulation could therefore be a therapeutic strategy in Duchenne Muscular Dystrophy (DMD) that arises from mutation in dystrophin gene. In contrast to its transcriptional regulation, mechanisms operating at post-transcriptional level of utrophin expression have not been well documented.

A monophasic solution for isolation of RNA devoid of polymerase chain reaction-detectable genomic DNA contamination.

Commercially available reagents and published protocols are widely used for RNA isolation. However, genomic DNA contamination in isolated RNA is a potential problem. Here we describe a simple, inexpensive method for eliminating genomic DNA contamination beyond the level of PCR-based detection through reduction of the guanidine thiocyanate concentration (1.

Translational regulation of utrophin by miRNAs.

Background: Utrophin is the autosomal homolog of dystrophin, the product of the Duchenne Muscular Dystrophy (DMD) locus. Its regulation is of therapeutic interest as its overexpression can compensate for dystrophin's absence in animal models of DMD. The tissue distribution and transcriptional regulation of utrophin have been characterized extensively, and more recently translational control mechanisms that may underlie its complex expression patterns have begun to be identified.

Differential expression of utrophin-A and -B promoters in the central nervous system (CNS) of normal and dystrophic mdx mice.

Utrophin (Utrn) is the autosomal homolog of dystrophin, the Duchene Muscular Dystrophy (DMD) locus product and of therapeutic interest, as its overexpression can compensate dystrophin's absence. Utrn is transcribed by Utrn-A and -B promoters with mRNAs differing at their 5' ends. However, previous central nervous system (CNS) studies used C-terminal antibodies recognizing both isoforms.

Heregulin-induced epigenetic regulation of the utrophin-A promoter.

Utrophin is the autosomal homolog of dystrophin, the product of the Duchenne's muscular dystrophy (DMD) locus. Utrophin is of therapeutic interest since its over-expression can compensate dystrophin's absence. Utrophin is enriched at neuromuscular junctions due to heregulin-mediated utrophin-A promoter activation.

Ets-2 repressor factor silences extrasynaptic utrophin by N-box mediated repression in skeletal muscle.

Utrophin is the autosomal homologue of dystrophin, the protein product of the Duchenne's muscular dystrophy (DMD) locus. Utrophin expression is temporally and spatially regulated being developmentally down-regulated perinatally and enriched at neuromuscular junctions (NMJs) in adult muscle. Synaptic localization of utrophin occurs in part by heregulin-mediated extracellular signal-regulated kinase (ERK)-phosphorylation, leading to binding of GABPalpha/beta to the N-box/EBS and activation of the major utrophin promoter-A expressed in myofibers.

An engineered EBV vector expressing human factor VIII and von Willebrand factor in cultured B-cells.

Background: Hemophilia A is a congenital disorder caused by a deficiency of the blood-clotting factor VIII (FVIII) and is an attractive candidate for gene therapy. Most of the studies have only explored the potential of hepatocytes and muscle cells as the targets for gene transfer. Attempts to transfer the genes into hematopoietic cells have so far been mostly unsuccessful due to inefficiency of most viral vectors to transduce these cells and the supposed inability of the cells to express FVIII.
