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

New plasmids containing the TATA-Binding Protein (TBP), TBP Promoter Binding Factor (TPBF) or Glyceraldehyde Phosphate Dehydrogenase (GAPDH) gene promoters from Acanthamoeba castellanii are described. The promoters for Acanthamoeba TPBF and GAPDH genes were used to drive constitutive expression of enhanced green fluorescent protein (EGFP) in stably transfected Acanthamoeba. Based initially on fluorescence microscopy and SDS-PAGE analysis of EGFP, both promoters produce robust expression of EGFP, with the highest level obtained from the GAPDH gene promoter in cells grown in low concentrations of neomycin G418. Purification of EGFP from lysates of 22-ml cultures by conventional chromatography yielded approximately 1.1mg of EGFP, a value that extrapolates to 50mg per liter of cell culture. The results suggest that Acanthamoeba is a useful cost-effective system for the production of recombinant proteins.
