RACE - Rapid Amplification of cDNA Ends

7.4K
Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific...

Conservative Site-specific Recombination and Phase Variation

6.9K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

Area of Science:

  • Molecular Biology
  • Gene Regulation
  • Oligonucleotide Therapeutics

Background:

  • RNA hacking (RNAh) is a gene regulation technology using Staple oligomers to form RNA G-quadruplex structures.
  • Current RNAh methods are limited to approximately 65% of human mRNAs due to sequence constraints.

Purpose of the Study:

  • To develop an improved RNAh system targeting a broader range of mRNAs.
  • To overcome sequence limitations in existing RNAh technology.

Main Methods:

  • Introduction of G-tract sequences into Staple oligomers to create Gs-Staple oligomers.
  • Testing Gs-Staple oligomer efficacy in suppressing target protein translation in mammalian cells and in vivo.
  • Modulating gene suppression by adjusting linker length between G-tracts.

Main Results:

  • Gs-Staple oligomers successfully expanded the range of targetable mRNAs.
  • Effective suppression of target protein translation was observed in cellular and in vivo models.
  • Precise modulation of gene suppression was achieved by altering linker lengths.

Conclusions:

  • Gs-Staple oligomers significantly enhance the versatility of RNAh technology.
  • This expanded RNAh framework holds potential for research and clinical applications as a nucleic acid-based tool.
