This study introduces GPU-BSM, a novel tool for analyzing DNA methylation. GPU-BSM efficiently maps bisulfite-treated sequencing reads, accelerating the detection of epigenetic modifications.

Area of Science:

  • Epigenetics
  • Genomics
  • Bioinformatics

Background:

  • Cytosine DNA methylation is a critical epigenetic mark influencing biological processes.
  • Bisulfite sequencing is the gold standard for studying DNA methylation, converting unmethylated cytosines to uracils.
  • Mapping bisulfite-treated reads to a reference genome is computationally intensive due to data alterations and increased search space.

Purpose of the Study:

  • To address the computational challenges in mapping bisulfite-treated sequencing reads.
  • To develop a high-performance tool for analyzing DNA methylation levels.
  • To accelerate the detection of epigenetic modifications using Graphics Processing Units (GPUs).

Main Methods:

  • Development of GPU-BSM, a tool leveraging Graphics Processing Units (GPUs) for accelerated read mapping.
