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 zonula occludens (ZO)-2 protein links tight junctional transmembrane proteins to the actin cytoskeleton and associates with splicing and transcription factors in the nucleus. Multiple posttranslational modifications control the intracellular distribution of ZO-2. Here, we report that ZO-2 is a target of the SUMOylation machinery and provide evidence on how this modification may affect its cellular distribution and function. We show that ZO-2 associates with the E2 SUMO-conjugating enzyme Ubc9 and with SUMO-deconjugating proteases SENP1 and SENP3. In line with this, modification of ZO-2 by endogenous SUMO1 was detectable. Ubc9 fusion-directed SUMOylation confirmed SUMOylation of ZO-2 and was inhibited in the presence of SENP1 but not by an enzymatic-dead SENP1 protein. Moreover, lysine 730 in human ZO-2 was identified as a potential modification site. Mutation of this site to arginine resulted in prolonged nuclear localization of ZO-2 in nuclear recruitment assays. In contrast, a construct mimicking constitutive SUMOylation of ZO-2 (SUMO1ΔGG-ZO-2) was preferentially localized in the cytoplasm. Based on previous findings the differential localization of these ZO-2 constructs may affect glycogen-synthase-kinase-3β (GSK3β) activity and β-catenin/TCF-4-mediated transcription. In this context we observed that ZO-2 directly binds to GSK3β and SUMO1ΔGG-ZO-2 modulates its kinase activity. Moreover, we show that ZO-2 forms a complex with β-catenin. Wild-type ZO-2 and ZO-2-K730R inhibited transcriptional activity in reporter gene assays, whereas the cytosolic SUMO1ΔGG-ZO-2 did not. From these data we conclude that SUMOylation affects the intracellular localization of ZO-2 and its regulatory role on GSK3β and β-catenin signaling activity.
