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

purposeCytochrome P450 (CYP) ω-hydroxylase, mainly consisting of CYP4A and CYP4F, converts arachidonic acid to 20-hydroxyeicosatetraenoic acid (20-HETE) that induces angiogenic responses in vivo and in vitro. The present study examined the role of CYP ω-hydroxylase in angiogenesis and metastasis of human non-small cell lung cancer (NSCLC).

methodsThe effect of WIT003, a stable 20-HETE analog, on invasion was evaluated using a modified Boyden chamber in three NSCLC cell lines. A549 cells were transfected with CYP4A11 expression vector or exposed to CYP ω-hydroxylase inhibitor (HET0016) or 20-HETE antagonist (WIT002), and then ω-hydroxylation activity toward arachidonic acid and the levels of matrix metalloproteinases (MMPs) and VEGF were detected. The in vivo effects of CYP ω-hydroxylase were tested in established tumor xenografts and an experimental metastasis model in athymic mice.

resultsAddition of WIT003 or overexpression of CYP4A11 with an associated increase in 20-HETE production significantly induced invasion and expression of VEGF and MMP-9. Treatment of A549 cells with HET0016 or WIT002 inhibited invasion with reduction in VEGF and MMP-9. The PI3 K or ERK inhibitors also attenuated expression of VEGF and MMP-9. Compared with control, CYP4A11 transfection significantly increased tumor weight, microvessel density (MVD), and lung metastasis by 2.5-fold, 2-fold, and 3-fold, respectively. In contrast, WIT002 or HET0016 decreased tumor volume, MVD, and spontaneous pulmonary metastasis occurrences.

conclusionCYP ω-hydroxylase promotes tumor angiogenesis and metastasis by upregulation of VEGF and MMP-9 via PI3 K and ERK1/2 signaling in human NSCLC cells.
