Targeted Subcellular Protein Delivery Using Cleavable Cyclic Cell-Penetrating Peptide-Conjugates.
Article in Methods in molecular biology (Clifton, N.J.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Proteins conjugated to cyclic cell-penetrating peptides (cCPPs) haAbstractve been shown to be effectively taken up by living cells. Conjugation of proteins to cCPPs in a cleavable manner leads to localization in the cytosol and immediate bioavailability of the protein after uptake. Here we describe how mCherry, a fluorescent protein, can be targeted to a membrane-bound compartment, the nucleus, and a subcellular structure like the actin cytoskeleton after cCPP-mediated uptake into living cells. Targeting peptides are genetically fused to the mCherry protein sequence and the protein is conjugated to the cCPP via a cleavable disulfide bond. Localization of mCherry in the nucleus or the actin skeleton respectively can be observed by live cell confocal fluorescence microscopy.
