The authors looked at gene expression in a panel of 50 ERBB2 (Her2) positive breast tumors and found that this pattern held up: DNA hypomethylation is associated with decreased gene expression in breast cancer.
Veland N, Hardikar S, Zhong Y, Gayatri S, Dan J, Strahl BD, Rothbart SB, Bedford MT, Chen T. (2017) The Arginine Methyltransferase PRMT6 Regulates DNA Methylation and Contributes to Global DNA Hypomethylation in Cancer.
Global DNA hypomethylation coupled to repressive chromatin domain formation and gene silencing in breast cancer Genome Research, 22 (2), 246 - 258 DOI: 10.1101 / gr.125872.111
In regions of DNA hypomethylation, H3K27me3 and H3K9me3 form repressive chromatin domains.
Such epigenetic mechanisms have already been exploited for diagnosis and treatment; for example, DNA hypomethylation therapy with 5 - azacytidine is approved for MDS and is in clinical trials for some other cancers.
Not exact matches
Recent genome - wide assays for DNA methylation have reported that global hypomethylation is a hallmark of breast and colon cancers.
Finally, we show that hypomethylation is associated with reduced levels of the de novo DNA methyltransferases Dnmt3a and Dnmt3b and that ectopic expression of these factors restores global methylation levels.
However, he did not mention that we also know that hypomethylation in DNA synthesis, which can occur with inadequate folate intake, can also cause DNA synthesis errors and chromosome breakage, which can initiate cancer formation.
