Principles and Experimental Workflow: How acRIP-seq & ac4C-seq Work
Understanding the technology behind ac4C analysis is key to choosing the right method for your research. Below, we outline the core principles and workflows for both acRIP-seq and ac4C-seq, offering insight into how each technique operates.
acRIP-seq
Principle:
acRIP-seq utilizes an antibody-based approach to identify and profile RNA fragments that are modified by ac4C across the transcriptome. By enriching for these modified regions, acRIP-seq enables the discovery of new ac4C targets in mRNA, lncRNA, and other RNA species.
Workflow:
- RNA Extraction and Fragmentation: The process begins with RNA extraction followed by fragmentation to ~100nt pieces.
- Antibody Enrichment: The fragmented RNA is incubated with a specific antibody that binds to ac4C-modified RNA. This step selectively enriches ac4C-modified regions.
- Library Construction: The enriched RNA fragments are reverse-transcribed into complementary DNA (cDNA) and prepared into sequencing libraries.
- Sequencing: The cDNA libraries are then sequenced using high-throughput sequencing technologies to generate detailed read data.
- Data Analysis: The sequencing data is analyzed to identify ac4C peaks, which are mapped to genomic features (e.g., CDS, UTRs) for further functional annotation. Differential analysis is performed to compare ac4C levels between experimental conditions.
ac4C-seq
Principle:
ac4C-seq is based on a chemical reduction method that induces a C→T mutation at ac4C modification sites in RNA. This allows for highly accurate, single-base resolution mapping of ac4C sites.
Workflow:
- RNA Preparation: RNA is first extracted and chemically reduced to convert ac4C to N4-ethyl-3,4,5,6-tetrahydropyrimidine.
- Reverse Transcription: During reverse transcription, the reduced RNA induces a C→T mutation at the site of ac4C modification.
- Library Construction: The cDNA is then prepared into sequencing libraries.
- Sequencing: These libraries are sequenced using high-throughput sequencing methods, enabling precise detection of ac4C sites at the nucleotide level.
- Data Analysis: The resulting data is analyzed to map mutation frequencies and validate ac4C sites with minimal false positives, providing a robust method for ac4C quantification and validation.
