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

A gene encoding phosphoglycerate kinase (PGK) was isolated from the genomic library of C. maltosa to construct an expression vector for this yeast. The PGK gene had an open reading frame of 1,251 base pairs encoding approximately 47-kDa polypeptide of 417 amino-acid residues. Expression of this gene assayed by Northern-blot analysis was significantly induced in cells grown on glucose but not in cells grown on n-tetradecane, n-tetradecanol, or oleic acid. By using the promoter region of this gene, an expression vector (termed pMEA1) for C. maltosa was constructed and expression of an endogenous gene (P450alk1 encoding one of cytochrome P450s for n-alkane hydroxylation in C. maltosa) and a heterologous gene (LAC4 encoding Kluyveromyces lactis beta-galactosidase) was tested. Expression of P450alk1 gene was confirmed at both mRNA and protein levels. LAC4 gene expression was confirmed by determining beta-galactosidase activity. The activity in cells grown on various carbon sources correlated very well with the expression levels of PGK mRNA in these cells.
