Cell-Permeable Stimuli-Responsive Ubiquitin Probe for Time-Resolved Monitoring of Substrate Ubiquitination in Live Cells.
Article in JACS Au, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Dynamic monitoring of intracellular ubiquitin (Ub) conjugates is instrumental to understanding the Ub regulatory machinery. Although many biochemical approaches have been developed to characterize protein ubiquitination, chemical tools capable of temporal resolution probing of ubiquitination events remain to be developed. Here, we report the development of the first cell-permeable and stimuli-responsive Ub probe and its application for the temporal resolution profiling of ubiquitinated substrates in live cells. The probe carrying the photolabile group N-(2-nitrobenzyl)-Gly (Nbg) on the amide bond between Ub Gly75 and Gly76 is readily prepared through chemical synthesis and can be delivered to live cells by conjugation via a disulfide bond with the cyclic cell-penetrating peptide cR10D (i.e., 4-((4-(dimethylamino)phenyl)-azo)-benzoic acid-modified cyclic deca-arginine). Both in vitro and in vivo experiments showed that Ub-modifying enzymes (E1, E2s, and E3s) could not install the Ub probe onto substrate proteins prior to removal of the nitrobenzyl group, which was easily accomplished via photoirradiation. The utility and practicality of this probe were exemplified by the time-resolved biochemical and proteomic investigation of ubiquitination events in live cells during a H
