  • The binding specificity of this antibody for human and mouse beta dystroglycan (beta-DG) was confirmed using ELISA. (absoluteantibody.com)
  • This antibody can also be used for the identification human beta-DG, mouse beta-DG and recombinant beta dystroglycan in a western blot. (absoluteantibody.com)
  • This antibody was also used for the immunofluorescent staining of unfixed human and mouse muscle tissues. (absoluteantibody.com)
  • An in vitro 3'UTR luciferase reporter assay further confirms that miR-146a inhibits dystrophin translation, while mutating the miR-146a binding site attenuates inhibition. (gene-tools.com)
  • A combination treatment of Simvastatin (Simva) and Temozolomide (TMZ) inhibits autophagy flux and induces unfolded protein response (UPR) in GBM cells (U251, U87). (mdpi.com)
  • Here we show that changes in the composition of the extracellular matrix during this week can affect cardiomyocyte growth and differentiation in mice. (nature.com)
  • CRISPR/Cas9 is a gene-editing technology which involves two essential components: a guide RNA to match a desired target gene, and Cas9 (CRISPR-associated protein 9)-an endonuclease which causes a double-stranded DNA break, allowing modifications to the genome (see figure 1 ). (bmj.com)
  • Cas9, one of the associated proteins, is an endonuclease that cuts both strands of DNA. (bmj.com)
  • Scientists at the Center for Genome Engineering, within the Institute for Basic Science (IBS) have used a variation of the popular gene editing technique CRISPR-Cas9 to produce mice with a single nucleotide difference. (medicilon.com)
  • In the current study, the investigators used a variation of the Cas9 protein (nickase Cas9, or nCas9) fused with an enzyme called cytidine deaminase, which can substitute one nucleotide into another-generating single-nucleotide substitutions without DNA deletions. (medicilon.com)
  • Their findings are published in Nature Biotechnology in an article entitled "Highly Efficient RNA-Guided Base Editing in Mouse Embryos. (medicilon.com)
  • We showed here for the first time that programmable deaminases efficiently induced base substitutions in animal embryos, producing mutant mice with disease phenotypes," remarked senior study investigator Jin-Soo Kim, Ph.D., director of the Center for Genome Engineering at IBS. (medicilon.com)
  • Excitingly, 146aX TAs showed increased dystrophin protein versus mdx52 as measured by capillary Western immunoassay and dystrophin-positive fiber quantification. (gene-tools.com)
  • We previously described microRNAs that are upregulated in DMD and BMD muscle biopsies, bind to the dystrophin 3'UTR and inhibit dystrophin protein production. (gene-tools.com)
