1 · What the graph read from it

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.

2 · The registry

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 introduction of new features or functions that are not present in an original protein is a significant challenge in protein engineering. For example, modifications to vesicular stomatitis virus glycoprotein (VSV-G), which is commonly used to pseudotype retroviral and lentiviral vectors for gene delivery, have been hindered by a lack of structural knowledge of the protein. We have developed a transposon-based approach that randomly incorporates designed polypeptides throughout a protein to generate saturated insertion libraries and a subsequent high-throughput selection process in mammalian cells that enables the identification of optimal insertion sites for a novel designed functionality. This method was applied to VSV-G in order to construct a comprehensive library of mutants whose combined members have a His6 tag inserted at likely every site in the original protein sequence. Selecting the library via iterative retroviral infections of mammalian cells led to the identification of several VSV-G-His6 variants that were able to package high-titer viral vectors and could be purified by Ni-nitrilotriacetic acid affinity chromatography. Column purification of vectors reduced protein and DNA impurities more than 5,000-fold and 14,000-fold, respectively, from the viral supernatant. This substantially improved purity elicited a weaker immune response in the brain, without altering the infectivity or tropism from wild-type VSV-G-pseudotyped vectors. This work applies a powerful new tool for protein engineering to construct novel viral envelope variants that can greatly improve the safety and use of retroviral and lentiviral vectors for clinical gene therapy. Furthermore, this approach of library generation and selection can readily be extended to other challenges in protein engineering.
