Abstract

Cellular senescence, an irreversible cell cycle arrest induced by a diversity of stimuli, has been considered as an innate tumor suppressing mechanism with implications and applications in cancer therapy. Using a targeted proteomics approach, we show that fibroblasts induced into senescence by expression of oncogenic R as exhibit a decrease of global acetylation on all core histones, consistent with formation of senescence‐associated heterochromatic foci. We also detected clear increases in repressive markers (e.g. >50% elevation of H 3 K 27me2/3) along with decreases in histone marks associated with increased transcriptional expression/elongation (e.g. H 3 K 36me2/3). Despite the increases in repressive marks of chromatin, 179 loci (of 2206 total) were found to be upregulated by global quantitative proteomics. The changes in the cytosolic proteome indicated an upregulation of mitochondrial proteins and downregulation of proteins involved in glycolysis. These alterations in primary metabolism are opposite to the well‐known W arburg effect observed in cancer cells. This study significantly improves our understanding of stress‐induced senescence and provides a potential application for triggering it in antiproliferative strategies that target the primary metabolism in cancer cells.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
