Summary
Small molecules offer precise control over CRISPR-Cas gene editing systems, enhancing safety and efficiency for in vivo somatic cell therapies by minimizing off-target effects and adverse events.
Area of Science:
- Biotechnology
- Genetics
- Molecular Biology
Background:
- CRISPR-Cas systems enable programmable gene editing but can cause genotoxicity and adverse events due to off-target cleavage.
- Translational challenges for in vivo somatic cell editing include viral vector limitations and host immune responses.
Purpose of the Study:
- To review strategies for controlling CRISPR-Cas systems in vivo.
- To focus on small molecules as regulatory switches for Cas genome editors.
Main Methods:
- Review of current strategies for conditional control of Cas systems.
- Focus on small molecule-based regulatory mechanisms.
Main Results:
- Small molecules, light, magnetism, and temperature are used to control Cas system activity.
- Small molecules can be incorporated as regulatory switches.
Conclusions:
- Small molecule regulation of CRISPR-Cas editors holds significant potential for improving in vivo somatic cell genome editing.
- This approach can increase editing efficiency while reducing adverse effects.

Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

CRISPR/Cas9 Genome Editing
760
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...

Conservative Site-specific Recombination and Phase Variation
6.3K
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.

CRISPR and crRNAs

Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.

Homologous Recombination
57.3K
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...
