Development of β-Hairpin Peptides for the Measurement of SCF-Family E3 Ligase Activity in Vitro via Ornithine Ubiquitination.

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
Regulation of the ubiquitin-proteasome system (UPS) to treat select types of cancer has become a popular area of drug discovery research. The FDA approval of proteasome inhibitors Bortezomib and Carfilzomib in the treatment of multiple myeloma has led to an increased need for chemical reporters capable of detecting and quantifying protein ubiquitination and the activity of members of the UPS including E3 ubiquitin ligases and the proteasome in the tumor cells of the patients. One limitation of peptide-based reporters is their rapid degradation in the cellular environment by cytosolic peptidases. Conversely, β-hairpin "protectides" exhibit a pronounced secondary structure that significantly increases their lifetime under cellular conditions. The goal of this work was to develop a family of novel, ornithine-rich protectides that could act as primary degrons serving as substrates for in vitro ubiquitination. The fluorescent peptide-based reporters were demonstrated to be highly resistant to degradation in multiple myeloma cell lysates. The most stable β-hairpin primary degron, containing a single ornithine residue at the N-terminus, OWRWR [Ac-OWVRVpGO(FAM)WIRQ-NH
