Background:

• MicroRNAs (miRNAs) are crucial regulatory molecules and a major focus in biological research.
• Detecting miRNA gene expression is challenging due to their small size, unlike longer RNAs like mRNA.
• Existing miRNA detection methods have limitations, necessitating the development of improved techniques.

Purpose of the Study:

• To introduce a novel and robust system for detecting miRNA gene expression.
• To provide a method with single-nucleotide resolution for precise miRNA detection.
• To develop a versatile system capable of distinguishing miRNA from its precursor.

Main Methods:

• The study presents a new system designed for miRNA expression detection.
• The system offers potential for single-molecule and multiplex detection capabilities.
• The method can be adapted to various formats, including polymerase chain reaction (PCR), blotting, or macroarray.

Main Results:

• The developed system can accurately distinguish between mature miRNA and its precursor molecules.
• The method achieves single-nucleotide resolution, enabling precise identification of miRNA sequences.
• The system demonstrates potential for detecting single miRNA molecules and analyzing multiple miRNAs simultaneously.

Conclusions:

• A new, personalized system for miRNA gene expression detection has been successfully developed.
• This system offers enhanced precision and flexibility compared to existing methods.
• The tool provides a convenient and powerful means for researchers studying miRNA expression.
