Transtactin: a universal transmembrane delivery system for Strep-tag II-fused cargos.
Article in Journal of cellular and molecular medicine, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The delivery of molecules into cells poses a critical problem that has to be solved for the development of diagnostic tools and therapeutic agents acting on intracellular targets. Cargos which by themselves cannot penetrate cellular membranes due to their biophysical properties can achieve cell membrane permeability by fusion to protein transduction domains (PTDs). Here, we engineered a universal delivery system based on PTD-fused Strep-Tactin, which we named Transtactin. Biochemical characterization of Transtactin variants bearing different PTDs indicated high thermal stabilities and robust secondary structures. Internalization studies demonstrated that Transtactins facilitated simple and safe transport of Strep-tag II-linked small molecules, peptides and multicomponent complexes, or biotinylated proteins into cultured human cells. Transtactin-introduced cargos were functionally active, as shown for horseradish peroxidase serving as a model protein. Our results demonstrate that Transtactin provides a universal and efficient delivery system for Strep-tag II-fused cargos.
