Leveraging DNA repair mechanisms in genetically engineered biocontrol

Area of Science:

• Genetics and Molecular Biology
• Biotechnology
• Bioengineering

Background:

• Gene drives are advanced genetic biocontrol strategies with potential for rapid, precise population modification.
• Endogenous DNA repair pathways significantly influence gene drive efficacy, either promoting or hindering success.
• Existing research primarily examines Homologous Recombination (HDR) and Non-Homologous End Joining (NHEJ) pathways.

Purpose of the Study:

• To review and highlight available tools and computational packages for analyzing gene editing events.
• To address the need for improved methods in predicting, detecting, and analyzing gene editing outcomes across diverse DNA repair pathways.
• To facilitate the design of more effective gene drives by considering a broader range of DNA repair mechanisms.

Main Methods:

• Literature review of scientific publications and bioinformatics tools.
• Exploration of computational packages and analytical methods for assessing gene editing events.
• Categorization of tools based on the DNA repair pathways they analyze (e.g., HDR, NHEJ, MMEJ, SSA).

Main Results:

• Identification of current limitations in analyzing gene editing events across all relevant DNA repair pathways.
• Overview of existing tools and methodologies applicable to gene drive research.
• Emphasis on the need for expanded analytical capabilities to include pathways like Microhomology-Mediated End Joining (MMEJ) and Single-Strand Annealing (SSA).

Conclusions:

• Developing and utilizing diverse analytical tools is essential for optimizing gene drive technology.
• A comprehensive understanding of DNA repair pathways, including MMEJ and SSA, is critical for advancing genetic biocontrol.
• Further development of predictive and analytical methods will enhance the precision and success of future gene drive applications.
