Effect of metformin on the epigenetic age of peripheral blood in patients with diabetes mellitus

Frontiers in Genetics, 2022
Background: Metformin has been proven to have an antiaging effect. However, studies on how metformin affects global epigenetic regulation and its effect on the epigenetic clock in diabetes mellitus (DM) patients are limited.

An evolutionary epigenetic clock in plants

Science, 2023
Molecular clocks are the basis for dating the divergence between lineages over macroevolutionary timescales (~10 5 to 10 8 years). However, classical DNA-based clocks tick too slowly to inform us about the recent past.

Circadian clock: linking epigenetics to aging [PDF]

Current Opinion in Genetics & Development, 2014
Circadian rhythms are generated by an intrinsic cellular mechanism that controls a large array of physiological and metabolic processes. There is erosion in the robustness of circadian rhythms during aging, and disruption of the clock by genetic ablation of specific genes is associated with aging-related features.

Centenarian clocks: epigenetic clocks for validating claims of exceptional longevity

GeroScience, 2023
Abstract Claims surrounding exceptional longevity are sometimes disputed or dismissed for lack of credible evidence. Here, we present three DNA methylation-based age estimators (epigenetic clocks) for verifying age claims of centenarians. The three centenarian clocks were developed based on n = 7039 blood and saliva samples from individuals older than ...

Epigenetic clock and methylation studies in elephants. [PDF]

Aging Cell, 2021
ABSTRACTAge-associated DNA-methylation profiles have been used successfully to develop highly accurate biomarkers of age (“epigenetic clocks”) in humans, mice, dogs, and other species. Here we present epigenetic clocks for African and Asian elephants.

Longitudinal Study of DNA Methylation and Epigenetic Clocks Prior to and Following Test-Confirmed COVID-19 and mRNA Vaccination

Frontiers in Genetics, 2022
The host epigenetic landscape rapidly changes during SARS-CoV-2 infection, and evidence suggest that severe COVID-19 is associated with durable scars to the epigenome.

Screening for genes that accelerate the epigenetic aging clock in humans reveals a role for the H3K36 methyltransferase NSD1

Genome Biology, 2019
Background Epigenetic clocks are mathematical models that predict the biological age of an individual using DNA methylation data and have emerged in the last few years as the most accurate biomarkers of the aging process.

A Novel Loop: Mutual Regulation Between Epigenetic Modification and the Circadian Clock

Frontiers in Plant Science, 2019
In response to periodic environmental fluctuations generated by the rotation of the earth, nearly all organisms have evolved an intrinsic timekeeper, the circadian clock, which can maintain approximate 24-h rhythmic oscillations in biological processes ...

Roles of physical exercise in neurodegeneration: reversal of epigenetic clock

Translational Neurodegeneration, 2021
The epigenetic clock is defined by the DNA methylation (DNAm) level and has been extensively applied to distinguish biological age from chronological age.

Estimating Polar Bear (Ursus maritimus) Age Based on an Epigenetic DNA Methylation Clock

Ecology and Evolution
Knowledge of animal age is essential to wildlife managers for obtaining meaningful and accurate insights into demographic parameters. A common approach to aging wildlife, including bears (Ursus spp.), has been extracting a tooth during physical capture ...
