Abstract
Background
Methylation changes within tumor suppressor (TS) genes or polycomb group target (PcG) genes alter cell fates. Chromatin associated with PcG targets is bivalent in stem cells, while TS genes are not normally bivalent. PcG target methylation changes have been identified in tumor stem cells, and abnormal methylation is found in TS genes in cancers. If the epigenetic states of genes influence DNA methylation, then methylation of PcG targets and TS genes may evolve differently during cancer development. More importantly, methylation changes may be part of a sequence in tumorigenesis.
Methods
Chromatin and methylation states of 4 PcG targets and 2 TS genes were determined in colon cancer cells. The methylation states were also detected in 100 pairs of colon cancer samples. Principle component analysis (PCA) was used to reveal whether TS methylation or PcG methylation was the main methylation change associated with colon cancers.
Results
Chromatin and methylation states differ in colon cancer cell lines. The methylation states within PcG targets clustered independently from the methylation states in TS genes, a finding we previously reported in liver cancers. PCA in colon cancers revealed the strongest association with methylation changes in 2 TS genes, HIC1 and RassF1A. Loss of HIC1 methylation correlated with decreased tumor migration.
Conclusions
PcG and TS methylation states cluster independently from each other. The deduced principle component correlated better with TS methylation than PcG methylation in colon cancer. Abnormal methylation changes may represent a sequential biomarker profile to identify developing colon cancer.
