SIRT2 mediates integrated stress response by deacetylating and stabilizing 4E-BP1 to suppress translation.
Article in EMBO reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The ability to adapt to nutrient stress, such as amino acid limitation, is crucial for cell survival. The mTORC1 complex and integrated stress response (ISR) are two mechanisms that sense the availability of amino acids and regulate protein synthesis. Here, we reveal a new SIRT2-mediated pathway, downstream of the ISR, that is activated under amino acids limitation to suppress global translation. Under amino acid deprivation, SIRT2 protein level is upregulated translationally by its upstream open reading frame (uORF). SIRT2 in turn suppresses translation, which helps cells to survive amino acid limitation. We identify eukaryotic translation initiation factor 4E (eIF4E) binding protein 1 (4E-BP1), which binds to eIF4E and inhibits translation, as a substrate of SIRT2. SIRT2 deacetylates 4E-BP1 at lysine 69 and stabilizes 4E-BP1 by protecting it from proteasomal degradation, leading to suppression of global translation. Our study uncovers a role for SIRT2 in regulating translation and identifies a new regulatory mechanism of 4E-BP1 in cells.
