The MuLV 4070A G541R Env mutation decreases the stability and alters the conformation of the TM ectodomain.

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
Virus-cell and cell-cell fusion events are affected by various properties of the fusogenic Env protein on the cell surface. The G541R mutation within the TM ectodomain of murine leukemia virus (MuLV) 4070A arose by positive selection in viral passage and results in a reduction of cell-cell fusion events while maintaining viral titer. Size exclusion chromatography shows that the multimerization properties are similar among expressed wild-type and mutant ectodomain peptides. Circular dichroism measurements reveal decreased thermal stability of the G541R mutant as compared to wild type. The G541R mutant also renders the peptide more susceptible to Lys-C protease cleavage. The 42-114 monoclonal antibody does not bind to the G541R mutant peptides, suggesting a structural difference from wild type. These altered physical properties result in productive viral infection of G541R bearing virus with decreased syncytia.
