Outline of Final Research Achievements |
Circulating Cell-free DNA (cfDNA) is known to be increased in multiple cancers reflecting necrosis and apoptosis of tumor tissue and is target for various genetic analysis. The global hypomethylation is thought to correlate with genomic instability and tumor progression. In this study, we quantified the global methylation status of cfDNA in plasma extracted from colorectal cancer (CRC) patients, and investigated its clinical usefulness as a biomarker.LINE-1 hypomethylation index (LHI) in plasma may have a potential to serve as a biomarker enabling us to detect CRC patient at early stage.
