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 overexpression of a regulatory gene of the TetR family (SCO3201) originating either from Streptomyces lividans or from Streptomyces coelicolor was shown to strongly repress antibiotic production (calcium-dependent antibiotic [CDA], undecylprodigiosin [RED], and actinorhodin [ACT]) of S. coelicolor and of the ppk mutant strain of S. lividans. Curiously, the overexpression of this gene also had a strong inhibitory effect on the sporulation process of S. coelicolor but not on that of S. lividans. SCO3201 was shown to negatively regulate its own transcription, and its DNA binding motif was found to overlap its -35 promoter sequence. The interruption of this gene in S. lividans or S. coelicolor did not lead to any obvious phenotypes, indicating that when overexpressed SCO3201 likely controls the expression of target genes of other TetR regulators involved in the regulation of the metabolic and morphological differentiation process in S. coelicolor. The direct and functional interaction of SCO3201 with the promoter region of scbA, a gene under the positive control of the TetR-like regulator, ScbR, was indeed demonstrated by in vitro as well as in vivo approaches.
