nc886 has also been suggested to be a tumor suppressor, mainly inferred by its expression pattern as well as its genomic location at human chromosome 5q31, a locus for a tumor suppressor gene(s). (oncotarget.com)
H. pylori infection associated DNA methylation is correlated with CIMP, specific molecular and clinicopathological features in GC, supporting its utility as promising biomarker in this tumor type. (hokudai.ac.jp)

It is widely accepted that cytosine methylation is a crucial regulatory mechanism in both normal and pathological processes. (biomedcentral.com)
We propose that modulation of DNA methylation in response to environmental cues early in life serves as a mechanism of life-long genome adaptation. (biomedcentral.com)
