Base editing: a brief review and a practical example.

Area of Science:

• Molecular Biology
• Genetics
• Biotechnology

Background:

• Genome editing technologies have advanced rapidly, offering precise gene modification capabilities.
• Base editing, a subset of genome editing, allows for specific nucleotide changes without double-strand breaks.

Purpose of the Study:

• To review the development of adenine and cytosine base-editing technologies.
• To discuss the diverse applications of base editing in both in vitro and in vivo systems.
• To practically demonstrate base editing for correcting a disease-causing mutation in human cells.

Main Methods:

• Review of existing literature on adenine and cytosine base editors.
• Description of various base editing strategies and their mechanisms.
• Experimental demonstration using cytosine and adenine base editors in human cell lines.

Main Results:

• Adenine and cytosine base editors enable targeted single-nucleotide conversions in the genome.
• Base editing has shown broad applicability in research and potential therapeutic applications.
• Successful introduction and correction of a hereditary tyrosinemia type 1 mutation using base editors in human cells.

Conclusions:

• Base editing represents a significant advancement in precise genome engineering.
• These technologies offer promising avenues for understanding and treating genetic disorders.
• The practical demonstration highlights the potential of base editing for therapeutic gene correction.
