Using archetype modeling and Gene Ontology analysis on data from aging &lt;i>Caenorhabditis elegans&lt;/i> worms, we find that the upregulated genes code for sensory proteins upstream of stress responses and downregulated genes are growth- and metabolism-related. We propose a simple mechanistic model for how such global coordination of multi-protein expression levels may be achieved by the binding of a single ligand that concentrates with age. A key implication is that a cell's own responses are part of its aging process, so unlike for wear-and-tear processes, intervention might be able to modulate these effects.</pubmed_abstract><journal>bioRxiv : the preprint server for biology</journal><pagination>2023.11.21.568122</pagination><full_dataset_link>https://www.ebi.ac.uk/biostudies/studies/S-EPMC10690170</full_dataset_link><repository>biostudies-literature</repository><pubmed_title>Transcriptional drift in aging cells: A global de-controller.</pubmed_title><pmcid>PMC10690170</pmcid><funding_grant_id>R35 GM122561</funding_grant_id><pubmed_authors>Matsuzaki T</pubmed_authors><pubmed_authors>de Graff A</pubmed_authors><pubmed_authors>Dill KA</pubmed_authors><pubmed_authors>Balazsi G</pubmed_authors><pubmed_authors>Weistuch C</pubmed_authors></additional><is_claimable>false</is_claimable><name>Transcriptional drift in aging cells: A global de-controller.</name><description>As cells age, they undergo a remarkable global change: In &lt;i>transcriptional drift&lt;/i>, hundreds of genes become overexpressed while hundreds of others become underexpressed.
