Correlations between vimentin methylation and relative expression levels in GC cell lines and tissues. Reverse transcription-quantitative polymerase chain reaction was used to analyze relative vimentin messenger RNA expression levels. A negative correlation was identified between vimentin DNA methylation and expression levels in (A) diffuse-type and (B) intestinal-type GC cell lines. (C and D) Comparable correlations were observed in diffuse- and intestinal-type of GC tissue. GC, gastric cancer.
