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

Streptomyces genus produces a large number of antibiotics, which are always synthesized by specific biosynthetic gene clusters (BGCs). To resist autotoxicity, transporters encoded by genes located within BGC occasionally pump antibiotic along with transporter encoded by gene located outside BGC. Daunorubicin is an anthracycline antibiotic biosynthesized by Streptomyces species, playing a crucial role in the treatment of leukaemia. In existing studies, only one two-component ATP-binding cassette (ABC) transporter, encoded by drrA1-drrB1 (abbreviated as drrAB1) and located within the daunorubicin BGC, has been proven to extrude daunorubicin. In this work, two other two-component ABC transporters, encoded by drrAB2 and drrAB3 and located outside the cluster, were found to play the complementary role in daunorubicin efflux in S. coeruleorubidus. Disruption of three drrABs resulted in a 94% decrease in daunorubicin production. Furthermore, drrAB2 is regulated by the TetR family regulator DrrR1, responding to the intracellular accumulation of daunorubicin and suggesting its role in stress response and self-resistance. Although the homologues of DrrAB1 are only found in three anthracycline BGCs, the homologues of DrrAB2 and DrrAB3 are spread in many Streptomyces strains which do not contain any known anthracycline BGC. This indicates that DrrAB2 and DrrAB3 may recognize and extrude a broader range of substrates besides daunorubicin, thus playing a more extensive role in cellular detoxification.
