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

Although preclinical work with rapalogs suggests potential in the treatment of gastric cancer, they have been less successful clinically. In this study, we report the impact of the investigational drug PP242, a potent and selective small-molecule active-site TORC1/2 kinase inhibitor, on tumor growth and metastasis. The antiproliferative effect of PP242 was assessed using the Cell Counting Kit-8 assay. The migration and invasion potential were analyzed using wound-healing and transwell assays, respectively. The Matrigel capillary tube formation assay was performed to mimic in-vivo angiogenesis. Immunoblotting and immunofluorescence were used to observe protein levels and distribution of actin fibers. Finally, p-mammalian target of rapamycin (mTOR) expression was detected on gastric cancer tissues using immunohistochemistry. First, PP242 potently inhibited cell proliferation in gastric cancer cell lines and in human endothelial cells in vitro at the IC50 ranged from 50 to 500 nmol/l. Then, an inhibitory effect of PP242 on metastasis was observed in gastric cancer cell AGS, along with the cytoskeletal rearrangements and suppression of the phosphorylation of PI3K downstream factors including AKT, mTOR, and P70S6K. Furthermore, PP242 was found to decrease the tube formation and migration of human umbilical vein endothelial cells. Using immunohistochemistry, we found that p-mTOR staining was observed in 41.8% (82/196) of gastric cancer tissues and correlated with depth of mural invasion, lymph node metastasis, tumor node metastasis stage, and vascular invasion. These results show that PP242 suppresses cell proliferation and angiogenesis of gastric cancer through inhibition of the PI3K/AKT/mTOR pathway, which might be an effective novel therapeutic candidate against gastric cancer in the future.
