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

Matrix metalloproteinases (MMP-2 and -9) play an important role in the tumor metastasis through cleavage of proinflammatory cytokines. Violacein a small molecule produced by Chromobacterium violaceum and has been implicated with anti-cancer effects. In this study we investigated the molecular basis of violacein mediated downregulation of CXCL12/CXCR4, chemokine-receptor ligand interaction. Zymography analysis demonstrated that violacein significantly inhibited the cytokine (TNFα and TGFβ) mediated MMP-2 activation in MCF-7 breast cancer cell line. MMP-2 plays a critical role in the secretion of inflammatory chemokine, CXCL12, involved in cell migration and cancer metastasis. ELISA analysis demonstrated that violacein inhibited the secretion of CXCL12 from the activated MCF-7 cells. Further, we show that MMP-2/-9 act synergistically at two distinct steps towards the membrane expression of the tumor metastasis chemokine receptor, CXCR4. Violacein efficiently downregulated the CXCR4 membrane expression through MMP-9 inhibition. Taken together, these studies demonstrate a unique anti-tumor mechanism of action of violacein through reduction of CXCL12/CXCR4 interaction. These studies could offer a novel venue for violacein in cancer therapy.
