Review links epigenetic drift and cell stress to senescence in aging
A review discusses how epigenetic changes and cell stress may lead to senescence, a process linked to aging and age-related diseases.

What the research shows
The review examines how epigenetic drift, meaning changes in how genes are switched on or off without altering the DNA itself, and cell stress may lead to cellular senescence. According to its authors' description, this process may drive aging and disease. As a review, it gathers and analyzes research already published on the topic rather than presenting a new experiment.
Cellular senescence is a state in which cells stop dividing but remain active and can release substances that affect nearby tissues. It is considered a possible contributor to aging and to age-related diseases, so reviews of its causes help organize knowledge in the field. Still, a review summarizes evidence and does not prove cause and effect in people; the details depend on the studies it includes.
What it means
The review suggests that epigenetic changes and cell stress are part of the chain that leads to senescence, a possible factor in aging. It is not yet clear which mechanisms matter most or how these findings translate to human health.
