Methods in Molecular Biology: DM Methodology

Publication of Methodology Useful for Research in DM

Methods in Molecular Biology is a long-running series disseminating research protocols and methodologies. A strength is the ability to precisely reproduce methodologies based upon step-by-step protocols.

In the latest release of Methods in Molecular Biology, six protocols from the myotonic dystrophy field are included. These include:

  • FISH techniques to detect expanded CUG repeat RNA or DMPK transcripts in DM1 plus a combined FISH/immunofluorescence protocol to visualize the colocalization of expanded repeat RNA and MBNL1 (Klein et al., 2020);
  • Methodology for in vitro synthesis and structure analysis of expanded CUG repeat RNA (van Cruchten and Wansink, 2020);
  • Technology for a tractable cell culture system to study instability of expanded CUG repeats; (Kononenko et al., 2020);
  • Use of FLP recombinase to construct HeLa clonal cell lines containing CNG repeats of various lengths at a single ectopic recombination acceptor site (Gadgil et al., 2020);
  • Design of PCR-based assays, using the model system Saccharomyces cerevisiae, to determine the behavior of expanded CTG tracts in stable and DM1 threshold ranges (Williams et al., 2020); and
  • Protocols for expanded repeat-primed PCR and restriction enzyme-digested PCR to detect/identify interrupted expanded repeat alleles in DM1 (Tomé and Gourdon, 2020).

MDF is including this item in the Research News to highlight the availability of these now-published research protocols.
