Cell-Based Assays for Smoothened Ubiquitination and Sumoylation.
Article in Methods in molecular biology (Clifton, N.J.), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 Hedgehog (Hh) family of secreted proteins governs embryonic development and adult tissue homeostasis by regulating the abundance, localization, and activity of the GPCR family protein Smoothened (Smo). Smo trafficking and subcellular accumulation are controlled by multiple posttranslational modifications (PTMs) including phosphorylation, ubiquitination, and sumoylation, which appears to be conserved from Drosophila to mammals. Smo ubiquitination is dynamically regulated by E3 ubiquitin ligases and deubiquitinases (dubs) and is opposed by Hh signaling. By contrast, Smo sumoylation is stimulated by Hh, which counteracts Smo ubiquitination by recruiting the dub USP8. We describe cell-base assays for Smo ubiquitination and its regulation by Hh and the E3 ligases in Drosophila. We also describe assays for Smo sumoylation in both Drosophila and mammalian cultured cells.
