Summary
Small DNA fragments enable precise genomic editing through small-fragment homologous replacement (SFHR). This gene editing technique shows promise for treating inherited diseases like cystic fibrosis and beta-thalassemia.
Area of Science:
- Molecular Biology
- Genetics
- Gene Editing
Background:
- Small DNA fragments can modify endogenous genomic DNA in human and mouse cells.
- The mechanisms underlying small-fragment homologous replacement (SFHR) require further characterization.
Purpose of the Study:
- To investigate the mechanisms of small-fragment homologous replacement (SFHR) for genomic editing.
- To assess the potential of SFHR as a therapeutic strategy for monogenic inherited diseases.
Main Methods:
- Employing genotypic and phenotypic analyses to evaluate SFHR.
- Utilizing SFHR to target disease-causing genetic loci.
Main Results:
- SFHR demonstrated specific modification of disease-associated genetic loci.
- Successful modification was observed for loci linked to cystic fibrosis, beta-thalassemia, and Duchenne muscular dystrophy.
Conclusions:
- SFHR is a viable strategy for sequence-specific genomic modification.
- SFHR holds significant therapeutic potential for treating monogenic inherited diseases.

Conservative Site-specific Recombination and Phase Variation
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.

DNA Isolation
DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...
Sanger Sequencing
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...
Next-generation Sequencing
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.

Restriction Enzymes
Restriction enzymes are bacterial enzymes used to cut DNA in a sequence-specific manner. To cleave DNA, they bind to specific palindromic sequences called restriction sites. Such palindromic DNA sequences or inverted repeats are commonly found in regions of functional significance, such as the origin of replication, gene operator sites, and regions containing transcription termination signals.

Maxam-Gilbert Sequencing
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.
