DNA Methylation
DNA methylation research studies chemical modifications of DNA that influence gene regulation, chromatin state, cellular identity, biological aging, disease mechanisms, and epigenomic biomarkers.
Research Overview
DNA methylation is one of the best-studied epigenomic mechanisms. By adding methyl groups to DNA, especially at CpG sites, cells can regulate gene activity, maintain cellular identity, control developmental programs, and respond to disease-associated regulatory disruption.
At PanorOmics, DNA methylation is presented as a core epigenomics research area: a bridge between genome regulation, gene expression, aging biology, cancer epigenomics, biomarker discovery, and precision medicine.
Core Research Areas
CpG Methylation Mapping
Studying DNA methylation patterns at CpG sites to understand gene regulation, promoter activity, chromatin state, and cellular identity.
Gene Regulation and Silencing
Analyzing how DNA methylation influences transcriptional repression, gene activity, imprinting, and regulatory control.
Developmental and Cell-State Methylation
Investigating methylation changes during development, differentiation, aging, disease progression, and cellular reprogramming.
Clinical Methylation Biomarkers
Using DNA methylation signatures to support disease classification, prognosis, early detection, aging research, and precision medicine studies.
DNA Methylation Technologies
