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

Gastric cancer represents a malignant type of cancer worldwide. Tanshinone IIA (Tan IIA), a pharmacologically active component isolated from the rhizome of the Chinese herb Salvia miltiorrhiza Bunge (Danshen), has been reported to possess an anti-cancer effect in gastric cancer. However, its mechanisms are still not fully understood. In the present study, we found that Tan IIA induced ferroptosis in BGC-823 and NCI-H87 gastric cancer cells. Tan IIA increased lipid peroxidation and up-regulated Ptgs2 and Chac1 expression, two markers of ferroptosis. Ferrostatin-1 (Fer-1), an inhibitor of lipid peroxidation, inhibited Tan IIA caused-lipid peroxidation and Ptgs2 and Chac1 expression. In addition, Tan IIA also up-regulated p53 expression and down-regulated xCT expression. Tan IIA caused decreased intracellular glutathione (GSH) level and cysteine level and increased intracellular reactive oxygen species (ROS) level. p53 knockdown attenuated Tan IIA-induced lipid peroxidation and ferroptosis. Tan IIA also induced lipid peroxidation and ferroptosis in BGC-823 xenograft model, and the anti-cancer effect of Tan IIA was attenuated by Fer-1 in vivo. Therefore, Tan IIA could suppress the proliferation of gastric cancer via inducing p53 upregulation-mediated ferroptosis. Our study have identified a novel mechanism of Tan IIA against gastric cancer, and might provide a critical insight into the application of Tan IIA in gastric cancer intervention.
