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

Neoangiogenesis is crucial for tumor growth and metastasis and is regulated by various angiogenic factors including vascular endothelial growth factor (VEGF). However, little is known whether highly metastatic cells express higher level of VEGF in response to various stimuli, thereby increasing neoangiogenesis compared to low-metastatic cells. Here we report that hypoxia markedly induced the expression of VEGF mRNA in the cell lines with high-metastatic potential (A11 and D6 cells) compared to the cell lines with low-metastatic potential (P29 and P34 cells) established from Lewis lung carcinoma. A11 cells exhibited higher VEGF gene-promoter activity, produced a larger amount of VEGF and showed higher activity to induce neoangiogenesis than P29 cells. Although the degradation rate of VEGF mRNA under hypoxic conditions was similar in both cell lines, hypoxia-inducible factor-1alpha (HIF-1alpha) mRNA, but not HIF-1beta mRNA, was found to be constitutively upregulated in A11 cells compared to P29 cells. Accordingly, the level of HIF-1alpha protein in response to hypoxia was higher in A11 cells than in P29 cells. Upregulation of HIF-1alpha mRNA was also observed in D6 cells but not in P34 cells. Thus, the high-metastatic cells produced a larger amount of VEGF under hypoxic conditions through constitutive HIF-1alpha mRNA upregulation compared to the low-metastatic cells, thereby leading to extensive neoangiogenesis.
