DNA methylation profiles (RRBS) of the muscle of pigs distinct in metabolic types and genetic background
DNA methylation is an epigenetic mechanism that plays roles in gene regulation and expression. This study aims to profile DNA methylation at genome-wide scale and single base resolution using reduced representation bisulfite sequencing (RRBS) of the muscle of pigs differing in muscle metabolism and genetic background. Pietrain homozygous- positive (PiPP) and negative (PiNN) for the ryanodine receptor mutation and malignant hyperthermia-susceptible (MHS), Duroc and F2 crossbred Duroc-Pietrain homozygous-negative (DuPi) pigs were investigated to identify differentially methylated CpG sites/ regions and to integrate the results with gene expression data.
