探索病毒感染时的^m6A和^m5C表继转录组:HIV示例

Executive Industry Relevance

Epitranscriptomic profiling of m⁶A and m⁵C RNA modifications enables biopharma teams to interrogate host-pathogen interactions at a regulatory layer beyond conventional transcriptomics. This workflow provides a quantitative atlas of differentially methylated transcripts in response to viral infection, supporting mechanistic de-risking and target validation in antiviral discovery. Integrating these insights can inform portfolio decisions and accelerate identification of novel host or viral factors modulating infection.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables systematic interrogation of RNA modification-driven regulatory mechanisms during viral infection.
• Supports functional target validation by mapping methylation changes to specific transcripts.
• Facilitates mechanistic de-risking by distinguishing direct epitranscriptomic effects from expression-level changes.
• Provides a resource for prioritizing candidate host or viral factors for further study.

Screening & Assay Development

• Delivers validated workflows for simultaneous detection of m⁶A and m⁵C marks in infected and control samples.
• Enables reproducible, quantitative measurement of methylation status at single-nucleotide resolution.
• Prepares high-quality RNA libraries suitable for high-throughput sequencing and downstream screening.
• Supports assay standardization for comparative studies across perturbations or compound treatments.

Translational & Preclinical Research

• Aligns epitranscriptomic changes with disease-relevant viral infection models.
• Enables continuity from discovery to preclinical validation by linking methylation signatures to functional outcomes.
• Supports identification of translational biomarkers reflecting host response to infection.
• Provides mechanistic context for risk-adjusted advancement of antiviral candidates.
