Summary
CRISPR gene editing causes DNA damage, activating the tumor suppressor p53. A CRISPR-p53 interactome of cancer genes may offer cells a selective advantage, necessitating monitoring and potential p53 inhibition in clinical gene therapy.
Area of Science:
- Biotechnology
- Genetics
- Cancer Research
Background:
- CRISPR/Cas9 gene editing holds promise for correcting disease-causing mutations.
- CRISPR/Cas9 induces DNA damage, activating the tumor suppressor p53 and its associated DNA damage response.
- The implications of this p53-centered response in the context of gene therapy are not fully understood.
Purpose of the Study:
- To discuss the implications of CRISPR/Cas9-induced DNA damage and the p53 response in gene therapy.
- To identify a CRISPR-p53 interactome comprising cancer-related genes.
- To propose strategies for monitoring and mitigating potential risks associated with CRISPR/Cas9 use in clinics.
Main Methods:
- Literature review and analysis of CRISPR/Cas9 mechanisms.
- Bioinformatic identification of a CRISPR-p53 interactome.
- Conceptualization of clinical monitoring and therapeutic intervention strategies.
Main Results:
- CRISPR/Cas9-induced DNA damage activates a p53-dependent response.
- A specific CRISPR-p53 interactome was identified, containing cancer-related genes.
- Mutations in these interactome genes can confer a selective advantage to cells post-CRISPR/Cas9 exposure.
Conclusions:
- The CRISPR-p53 interactome represents a potential risk in clinical gene therapy settings.
- Monitoring genes within this interactome is recommended for patients undergoing CRISPR/Cas9 treatment.
- Transient inhibition of p53 may reduce the enrichment of cells with advantageous mutations.

CRISPR/Cas9 Genome Editing
455
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...

CRISPR
53.1K
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 and crRNAs
17.5K
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.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

Homologous Recombination
53.3K
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...

Interactions Between Signaling Pathways
6.6K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
