Outline of Final Research Achievements

Global DNA hypomethylation is associated with increased chromosomal instability and plays an important role in tumorigenesis. The methylation status of the long interspersed nuclear element-1 (LINE-1) element is a useful surrogate marker for global DNA methylation. Using resected tumor tissues and the corresponding normal colorectal cancer, bisulfite pyrosequencing analysis was performed to quantify the LINE-1 methylation levels. p53 mutations in exons two to ten were detected by polymerase chain reaction direct sequencing. Chromosomal instability was assessed by single nucleotide polymorphism array comparative genomic hybridization analysis. The LINE-1 methylation level of colorectal cancer was lower than matched normal mucosa. The LINE-1 methylation levels in colorectal cancer had a significant inverse association with the methylation in the MLH1.
