[Influence of Berberine on Cisplatin Antineoplastic Effect in A549 Cells].

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.
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
BACKGROUND AND
objectiveCisplatin is a standard first-line chemotherapeutic agents for treating advanced non-small cell lung cancer. Unfortunately, the clinical application cisplatin is restricted because it induces serious adverse reaction. The aim of this study is to investigate the influence and probable mechanism of berberine on cisplatin antineoplastic effect on lung cancer A549 cells.
methodsThe total Cx43 protein amount, localization of Cx43 on cell membrane, and gap junction function were observed after the A549 cells were treated with berberine. The influence of berberine on the antitumor action of cisplatin was detected by standard colony-forming assay. Protein kinase C (PKC) protein, which regulates the gap junction, was subsequently determined.
resultsBerberine did not affect cell survival at concentrations of 0 μM to 10 μM in the A549 cells. The gap junction function between the cells was enhanced through increased Cx43 protein expression and localization of Cx43 on the membrane after berberine treatment. The intercellular dye coupling through gap junction increased when the cells exposed to 0.1 μM, 1 μM, 10 μM berberine [33.3% (P=0.002,3), 67.0% (P<0.001), 160.0% (P<0.001)] compared withcontrols. This effect was associated with the PKC activity. The cisplatin-induced inhibition of colony growth was enhanced when berberine was combined with cisplatin.
conclusionsBerberine can obviously increase the antitumor effect of cisplatin by enhancing the function of the gap junction possibly in A549 cells. .
