ABSP

ABSP analyzes region-specific CpG methylation from bisulfite sequencing PCR (.ab1) data to compute methylation percentages for epigenetic studies.


Key Features:

  • R-based implementation: Implemented in R for computational analysis of bisulfite sequencing PCR data.
  • Supported BSP methodologies: Supports both direct-BSP and cloning-BSP approaches for region-specific bisulfite sequencing.
  • Raw trace file processing: Processes raw sequencing trace files (.ab1) derived from bisulfite-treated DNA.
  • Methylation quantification: Computes CpG methylation percentages and distinguishes methylated from unmethylated cytosines.
  • Quality control integration: Integrates quality control checks to ensure reliability and accuracy of methylation percentage calculations.
  • Automated workflow: Automates analysis steps including data input, quality control, analysis, and visualization.
  • Publication-ready outputs: Generates publication-quality graphics and comprehensive reports.

Scientific Applications:

  • Epigenetic research: Enables precise quantification of CpG methylation to study epigenetic gene regulation across contexts such as embryonic development, cancer, and neurodegenerative disorders.
  • Cancer studies: Facilitates identification of aberrant methylation patterns that may serve as biomarkers or therapeutic targets in oncology research.
  • Neurodegenerative disorders: Supports investigation of epigenetic changes associated with neurodegenerative disease mechanisms.

Methodology:

Processes raw .ab1 sequencing trace files to compute CpG methylation percentages from bisulfite-treated DNA, employs robust algorithms to distinguish methylated and unmethylated cytosines, and executes an automated workflow comprising data input, quality control checks, analysis, visualization, and report generation.
