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

Cancer cell invasion is one of the crucial events in local spreading, growth and metastasis of tumors. The present study investigates the mechanism underlying the anti-invasive action of the chemotherapeutic cisplatin. In human cervical carcinoma cells (HeLa), cisplatin caused a time- and concentration-dependent suppression of cell invasion through Matrigel. Inhibition of invasion was accompanied by upregulation of tissue inhibitor of matrix metalloproteinases-1 (TIMP-1), whereas levels of matrix metalloproteinase-2 (MMP-2), MMP-9 and TIMP-2 remained unchanged. Cisplatin's effects on TIMP-1 expression and invasion were associated with phosphorylations of p38 and p42/44 mitogen-activated protein kinases and were abrogated by specific inhibitors of both pathways. The impact of TIMP-1 in the anti-invasive action of cisplatin was proven by transfecting cells with small interfering RNA targeting TIMP-1, which completely reversed suppression of invasion by cisplatin. A functional relevance of TIMP-1 upregulation was substantiated by findings showing a concentration-dependent inhibition of Matrigel invasion by recombinant TIMP-1. The essential role of TIMP-1 in the anti-invasive action of cisplatin was confirmed using another human cervical carcinoma cell line (C33A) and human lung carcinoma cells (A549). Altogether, our data demonstrate a hitherto unknown mechanism by which cisplatin exerts its antimetastatic properties on highly invasive cancer cells.
