SINE compounds activate exportin 1 degradation through an allosteric mechanism.
Article in Nature chemical biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Overexpression of exportin 1 (XPO1/CRM1) in cancer cells mislocalizes numerous cancer-related nuclear export cargoes. Covalent selective inhibitors of nuclear export (SINEs), including the cancer drug selinexor, restore proper nuclear localization by blocking XPO1-cargo interaction. These inhibitors also induce XPO1 degradation through the Cullin-RING E3 ligase (CRL) substrate receptor ASB8. Here we present cryo-electron microscopy structures revealing ASB8 binding to a cryptic XPO1 site that is exposed upon SINE conjugation. Unlike typical molecular glue degraders that directly bridge CRLs and substrates, SINEs bind XPO1 independently of ASB8, triggering an allosteric mechanism that enables high-affinity ASB8 recruitment, leading to XPO1 ubiquitination and degradation. ASB8-mediated degradation is also triggered by the endogenous itaconate derivative 4-octyl itaconate, suggesting that synthetic XPO1 inhibitors exploit a native cellular mechanism. This allosteric XPO1 degradation mechanism expands known modes of targeted protein degradation beyond molecular glue degraders and proteolysis-targeting chimeras of CRL4.
