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 sequence of the Neocallimastix frontalis enolase gene promoter was determined up to 1800 nucleotides 5' to the major transcriptional start point. The base composition of the enolase upstream sequence revealed a very A + T-rich profile (13.5% G + C) leading to many putative hairpin structures. The functional organization of the N. frontalis enolase promoter was investigated by heterologous transient-expression assays. DNA fragments obtained by the sequential removal of sequences upstream of the translation start codon were fused to the Escherichia coli lacZ gene and the resulting plasmids were used to transform the ascomycetes Aspergillus nidulans and Penicillium roqueforti and the oomycete Saprolegnia monoica. Transient expression of the lacZ reporter gene was observed in regenerating proteoplasts of S. monoica when using the 0.3 kb or 1 kb upstream of the enolase coding region. In contrast no beta-galactosidase activity was detected in ascomycete protoplasts. DNA hybridization analysis revealed the integration of vector DNA in the genomic DNA of S. monoica and the presence of free copies of the transformation plasmid which could be rescued in E. coli. Our results indicate that the transcriptional machinery of the anaerobic chytrid N. frontalis may differ significantly from that of ascomycetes but that enough conservation exists within the lower fungi to allow a transient-driven expression of a reporter gene in an oomycete fungus.
