Summary
Oligonucleotide-mediated gene editing in mammalian cells is a real phenomenon, not an artefact. Rigorous experiments confirm its validity, paving the way for practical applications in genetic technology.
Area of Science:
- Molecular Biology
- Genetics
- Biotechnology
Background:
- Targeted genomic editing using synthetic oligonucleotides has been reported but faced skepticism due to reproducibility issues and potential experimental artifacts.
- Discrepancies in findings and low reproducibility have led to disputes regarding the validity of oligonucleotide-mediated gene editing.
- There is a need for stringent experimental validation to confirm the authenticity of this gene editing technique.
Purpose of the Study:
- To unequivocally authenticate oligonucleotide-mediated gene editing in mammalian cells.
- To design experiments that rigorously exclude potential artefactual results and ensure data integrity.
- To establish a reliable foundation for the future development of oligonucleotide-mediated gene editing technologies.
Main Methods:
- Utilized cells expressing mutated enhanced green fluorescence protein (EGFP) to enable protein-level measurement of gene editing.
- Employed Southern blotting to analyze corrected clones, ensuring accurate assessment of genetic modifications.
- Implemented stringent experimental controls to eliminate spontaneous reversion, contamination, false-positives, and overestimation of editing events.
Main Results:
- Provided definitive evidence confirming that oligonucleotide-mediated gene editing is a genuine biological phenomenon.
- Successfully excluded all potential sources of experimental artefacts, including spontaneous reversion and contamination.
- Demonstrated the reliability and reproducibility of gene editing mediated by synthetic oligonucleotides under rigorous conditions.
Conclusions:
- Oligonucleotide-mediated gene editing is a validated and authentic phenomenon in mammalian cells.
- The study provides a critical starting point for advancing this technology towards practical applications.
- Future research can now focus on optimizing and implementing oligonucleotide-mediated gene editing for therapeutic and research purposes.

02:23RNA Editing
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...
02:31Homologous Recombination
The basic reaction of homologous recombination (HR) involves two chromatids that contain DNA sequences sharing a significant stretch of identity. One of these sequences uses a strand from another as a template to synthesize DNA in an enzyme-catalyzed reaction. The final product is a novel amalgamation of the two substrates. To ensure an accurate recombination of sequences, HR is restricted to the S and G2 phases of the cell cycle. At these stages, the DNA has been replicated already and the...

The CRISPR-Cas system serves as a bacterial defense mechanism against invading genetic elements such as viruses and plasmids, forming the foundation for its adaptation as a powerful genome-editing tool. Originally discovered in prokaryotes, this system has been repurposed to revolutionize genetic engineering across a wide range of organisms, including plants, animals, and humans. The core component, Cas9, is an endonuclease derived from Streptococcus pyogenes, capable of introducing...
