DNA Methylation in Cancer and Aging

Cancer Research, 2016
Abstract DNA methylation is known to be abnormal in all forms of cancer, but it is not really understood how this occurs and what is its role in tumorigenesis. In this review, we take a wide view of this problem by analyzing the strategies involved in setting up normal DNA methylation patterns and understanding how this stable epigenetic

DNA methylation in cancer and ageing

Mechanisms of Ageing and Development, 2002
Epigenetic gene silencing through DNA methylation is now clearly thought to be one of the important steps in the mechanism underlying tumourigenesis. The methylation of several genes increases with age in normal tissues such as the colon. Methylation related to cancer and ageing may lead to new biomarkers and therapeutic concepts for cancer.

Impact of aging on DNA methylation

Ageing Research Reviews, 2003
The biochemistry of aging is complex, with biologically significant changes occurring in proteins, lipids and nucleic acids. One of these changes is in the methylation of DNA. DNA methylation is a mechanism modifying gene expression. The methylation of sequences in or near regulatory elements can suppress gene expression through effects on DNA binding ...

DNA Methylation in Aging and Cancer

Journal of Gerontology, 1989
DNA methylation processes appear to be disturbed in senescing mice and also in some tumor cells. Although it is possible that age-related demethylation of DNA could predispose cells to carcinogenic transformation, present evidence does not favor this hypothesis.

DNA methylation, ageing and ribosomal genes activity

Biogerontology, 2000
DNA methylation is an epigenetic mechanism controlling of gene expression. We studied the effect of a demethylation agent 5-azacytidine, on ribosomal gene activity observed by Nucleolus Staining Giemsa in the chromosomes of eight Alzheimer's disease patients, eight elderly healthy individuals and eight young healthy controls.

DNA methylation in cognition comes of age

Nature Neuroscience, 2012
A study reveals that aged mice have decreased hippocampal expression of the DNA methyltransferase Dnmt3a2; re-expression in aged mice reverses memory deficits, and knockdown in young mice impairs memory formation.

Age-related DNA methylation changes for forensic age-prediction

International Journal of Legal Medicine, 2014
There is no available method of age-prediction for biological samples. The accumulating evidences indicate that DNA methylation patterns change with age. Aging resembles a developmentally regulated process that is tightly controlled by specific epigenetic modifications and age-associated methylation changes exist in human genome.

Defective DNA Methylation/Demethylation Processes Define Aging-Dependent Methylation Patterns

2018
The process of aging culminates in a multitude of chronological irreversible changes at the cellular and molecular levels that push the organism toward a progressive loss of physiological integrity and increased susceptibility to disease. Mounting evidence indicates that aging trajectories can be closely tracked down by changes in the DNA methylation ...
