Loose Chromatin, Senescent Inflammation, and Cancer
August 28, 2025
In Aging Cell, researchers have reported that chromatin demethylation allows SASP compounds to be more easily expressed. Chromatin and gene expression The authors of this study begin by discussing two concepts that appear only loosely related: senescence and gene expression. Both of these concepts are very
