RNA delivery in Saccharomyces cerevisiae using electroporation

Area of Science:

• Molecular Biology
• Yeast Genetics
• Biotechnology

Background:

• Investigating gene function in yeast often requires methods to introduce specific RNA molecules.
• Existing methods may be time-consuming or limited in the types of RNA that can be delivered.
• Understanding cytoplasmic regulatory mechanisms requires direct delivery of RNA.

Purpose of the Study:

• To establish an efficient and rapid method for introducing in vitro synthesized RNA into yeast.
• To enable studies on cytoplasmic gene regulation using externally supplied RNA.
• To facilitate the introduction of modified or non-native RNA molecules into yeast.

Main Methods:

• Development of a streamlined protocol for yeast spheroplast preparation and electroporation.
• Optimization of electroporation parameters for efficient RNA delivery.
• Assessment of reporter gene expression (GUS and luciferase) following RNA introduction.

Main Results:

• Electroporation allows RNA delivery into yeast spheroplasts within a single day.
• Introduced mRNA bypasses nuclear regulation, suitable for cytoplasmic studies.
• The method successfully delivered poly(A)- mRNAs and base-modified RNAs.
• Escherichia coli GUS and firefly luciferase genes serve as effective reporter genes.

Conclusions:

• Electroporation provides an efficient delivery method for synthetic RNA in yeast.
• This technique is valuable for studying cytoplasmic regulation and non-native RNAs.
• The developed method offers a rapid, single-day workflow for RNA expression analysis in yeast.
