Matrix metalloproteinase-1 contribution to sarcoma cell invasion.
Article in Journal of cellular and molecular medicine, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Matrix metalloproteinase-1 (MMP-1) activity has been linked to numerous disease processes from arthritis to ulcer. Its proteolytic activity has been implicated inconsistently in different steps of tumourigenesis and metastasis. The discrepancies may be attributable to our limited understanding of MMP-1 production, cellular trafficking, secretion and local activation. Specifically, regulation of MMP-1 directional delivery versus its general extracellular matrix secretion is largely unknown. Inhibition of prenylation by farnesyl transferase inhibitor (FTI-276) decreased extracellular MMP-1 and subsequently reduced invasiveness by 30%. Parallel, stable cell line RNAi knockdown of MMP-1 confirmed its role in cellular invasiveness. The prenylation agonist farnesyl pyrophosphate (FPP) partially normalized FTI-276 inhibited extracellular MMP-1 levels and invasion capacity while transiently delayed its cellular podia distribution. MMP-1 directional delivery to these structures were confirmed by combination of a MMP-1-specific fluorogenic substrate, a MMP1-Ds-Red fusion protein construct expression and DQ-collagen degradation, which demonstrated coupling of directional delivery and activation. MetaMorph analysis of cellular lamellipodia structures indicated that FTI-276 inhibited formation and delivery to these structures. Farnesyl pyrophosphate partially restored lamellipodia area but not MMP-1 delivery under the time frame investigated. These results indicate that MMP-1 directional delivery to podia structures is involved in the invasive activity of sarcoma cells, and this process is prenylation sensitive.
