Abstract excerpt
Silencing of the MLH1 gene by promoter hypermethylation is the mechanism underlying the microsatellite instability (MSI) phenotype in endometrial cancers. However, the profile of CpG methylation in a wide range of MLH1 promoters in endometrial cancers and in the normal endometrium is largely unknown. The present study investigates the region 700 bp upstream of MLH1 covering 48 CpG sites using bisulfite...
