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

purposeGastric cancer (GC) is one of the most fatal digestive tumors worldwide. Abnormal activation or accumulation of the nuclear factor-erythroid 2-related factor 2/heme oxygenase 1 (Nrf2/HO-1) axis is a malignant event in numerous solid tumors. However, its involvement in angiogenesis of GC remains unknown. This study investigated the role of the Nrf2/HO-1 axis in angiogenesis of GC.

methodsThe expression of Nrf2, HO-1, and vascular endothelial growth factor (VEGF) in BGC-823 cells under hypoxia was analyzed using immunocytochemistry, immunofluorescence, Western blotting, and quantitative polymerase chain reaction. The effects of brusatol (Nrf2 inhibitor) and tert-butylhydroquinone (Nrf2 inducer) on these factors and angiogenesis were examined using immunofluorescence, Western blotting, quantitative polymerase chain reaction, and tube formation assay. Moreover, immunohistochemistry and Western blotting were used to determine these factors and microvessel density in tumor and normal tissues of tumor-bearing and tumor-free mice, respectively. Immunohistochemistry and Western blotting were employed to examine these factors and microvessel density in human paracancerous tissues, well-differentiated GC, and poorly differentiated GC. The correlations between Nrf2, HO-1, and VEGF gene expression in 375 patients with GC from The Cancer Genome Atlas cohort were analyzed.

resultsThe expression of Nrf2, HO-1, and VEGF was increased in hypoxic BGC-823 cells (

conclusionThe Nrf2/HO-1 axis may regulate the angiogenesis of GC via targeting VEGF. These findings provide a promising biomarker and potential treatment target for GC.
