Sentence examples for changes in methylation over time from inspiring English sources
Changes in methylation over time occurred in 15 gene regions.
However, the most significant differences were observed when changes in methylation over time from birth to age 4.5 years were compared between children that developed asthma and those that did not (own unpublished data).
In addition, the discovery of circulating tumor DNA could provide an opportunity to monitor changes in methylation over time, enabling an unprecedented glimpse into the methylation changes associated with anti-estrogen resistance.
In support of this playing at least a partial role in the observed change in methylation over time, we found a slightly higher correlation between the methylation profile of purified primary cytotrophoblasts with first trimester placental tissue (R2 = 0.96) than with third trimester tissue (R2 = 0.88; see Additional file 8).
Yet little is known about intra-individual changes in DNA methylation over time in relationship to environmental exposures.
Monitoring changes in CDKN2B methylation over time would also prove useful in assessing residual disease.
The observation of dynamic changes in DNA methylation over time highlights the importance of longitudinal research designs for epigenetic research.
Apart from the 'clock-specific' age signatures, without this information it is impossible to attribute changes in DNA methylation over time to intrinsic age-specific effects.
A longitudinal examination of DNA methylation across genes previously associated with ADHD suggests that methylation differences in those genes are already apparent in early childhood even among identical twins, and that individual changes in methylation are not stable over time [ 40].
Although the full biological significance of dynamic changes in tissue-specific DNA methylation over time has yet to be elucidated, the patterns and magnitude of differences indicate many of the changes seen here are programmed rather than stochastic changes.
Because DNA methylation has been associated with age-related diseases, the study of intra-individual changes in gene-specific DNA methylation over time is of utmost importance.
