The mu-1 opioid receptor gene (OPRM1) is known to play an important role in opioid-pain pathways. Since deoxyribonucleic acid (DNA) methylation is a potent repressor of gene expression, DNA methylation was evaluated at the OPRM1 promoter, as a predictor of preoperative, acute, and chronic postsurgical pain (CPSP) %K OPRM1 %K epigenetics %K pain %K chronic postsurgical pain %K DNA methylation %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5432115/
