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

backgroundCasticin is one of the main active components obtained from Fructus Viticis and has been reported to exert anti-carcinogenic activity on a variety of cancer cells but the precise mechanism underlying this activity remains unclear. MATERIALS AND

methodsApoptotic activities of casticin (1.0 µmol/l) and TRAIL (25, 50 ng/ml) alone or in combination in the gastric cancer cell lines BGC-823, SGC-7901 and MGC-803 were detected by the use of a cell apoptosis ELISA detection kit, flow cytometry (FCM) with propidium iodide (PI) staining and activities of caspase-3, -8 and -9 by ELISA and cleavage of polyADP-ribose polymerase (PARP) protein using western blot analysis. Death receptors (DR) expression levels were evaluated using FCM analysis and western blotting. 2', 7'-dichlorofluorescein diacetate (DCFH-DA) was used as a probe to measure the increase in reactive oxygen species (ROS) levels in cells. Multiple interventions, such as siRNA transfection and pharmacological inhibitors were used to explore the mechanisms of these actions.

resultsSubtoxic concentrations of casticin significantly potentiated TRAIL-induced cytotoxicity and apoptosis in BGC-823, SGC-7901 and MGC-803 cells. Casticin dramatically upregulated DR5 receptor expression but had no effects on DR4 or decoy receptors. Deletion of DR5 by siRNA significantly reduced the apoptosis induced by the co-application of TRAIL and casticin. Gene silencing of the CCAAT/enhancer binding protein homologous protein (CHOP) and pretreatment with salubrinal, an endoplasmic reticulum (ER) stress inhibitor, attenuated casticin-induced DR5 receptor expression, and apoptosis and ROS production. Casticin downregulated the expression levels of the cell survival proteins cFLIP, Bcl-2, XIAP, and survivin. In addition, casticin also induced the expressions of DR5 protein in other gastric cancer cells (SGC-7901 and MGC-803). CONCLUSION/SIGNIFICANCE: Casticin enhances TRAIL-induced apoptosis through the downregulation of cell survival proteins and the upregulation of DR5 receptors through actions on the ROS-ER stress-CHOP pathway.
