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

Multidrug resistant (MDR) cancer cells overexpressing P-glycoprotein (P-gp) display variations in invasive and metastatic behavior. We aimed to clarify the mechanism(s) underlying this observation and transfected vectors carrying CD147, a glycoprotein enriched on the surface of tumor cells that stimulates the production of matrix metalloproteinases (MMPs), and specific shCD147 into MCF7 and MCF7/Adr cells, respectively. Using quantitative real-time polymerase chain reaction and Western blot, we found that overexpression of CD147 in MCF7 cells up-regulated MDR1, MMP2, and MMP9 on both transcription and expression levels, which promoted tumor cells metastasis and conferred them multidrug resistance to P-gp substrate drugs, as determined by in vitro invasion assay and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. On the other hand, silencing of CD147 in MCF7/Adr cells led to the opposite effect. Moreover, Erk1/2 in CD147-overexpressing clones were observed to be highly activate and after treatment with U0126, an Erk1/2-specific inhibitor, the expression of MDR1, MMP2 and MMP9 were decreased significantly. Thus, CD147 may assume a dual role, since it had intrinsic stimulative effects on tumor invasion in vitro as well as increasing resistance to P-gp substrate drugs.
