Summary
This study introduces a novel Bis-enzyme cascade Platform (BPTC) for sensitive and specific microRNA (miRNA) detection. The BPTC combines T7 RNA polymerase and CRISPR-Cas12a for enhanced miRNA biomarker discovery.
Area of Science:
- Biochemistry
- Molecular Biology
- Biotechnology
Background:
- MicroRNAs (miRNAs) are crucial in disease pathology and serve as diagnostic and prognostic biomarkers.
- Current miRNA detection methods require improvement in sensitivity and specificity.
Purpose of the Study:
- To develop a novel, highly sensitive, and specific biosensor for microRNA (miRNA) detection.
- To establish an all-in-one detection strategy for miRNA analysis using a bis-enzyme cascade system.
Main Methods:
- A Bis-enzyme cascade Platform (BPTC) was designed, integrating T7 RNA polymerase, phi29 amplification, and CRISPR-Cas12a.
- The platform utilizes target miRNA to initiate RNA-to-DNA conversion, amplification, and subsequent CRISPR-Cas12a activation for signal generation.
Main Results:
- The BPTC biosensor demonstrated high sensitivity and excellent specificity in miRNA detection.
- The system successfully combined enzymatic amplification with CRISPR-Cas12a trans-cleavage for signal amplification.
Conclusions:
- The proposed BPTC offers a novel and efficient strategy for miRNA detection.
- This approach may inspire new designs for CRISPR-Cas-based miRNA biosensing platforms.

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...

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...

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...
