Longistyline C acts antidepressant in vivo and neuroprotection in vitro against glutamate-induced cytotoxicity by regulating NMDAR/NR2B-ERK pathway in PC12 cells.
Article in PloS one, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers.
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.
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
Depressive disorder is a common psychiatric disease which ranks among the leading cause of disability worldwide. The antidepressants presently used had low cure rate and caused a variety of side-effects. The screening of antidepressant drugs is usually used classic behavioural tests and neuroprotective strategy. Longistyline C, a natural stilbene isolated from the leaves of Cajanuscajan (L.) Millsp, was firstly investigated the antidepressant effect using animal behavioural tests, and studied the neuroprotection and its possible signaling pathways on glutamate-induced injury in PC12 cells. The results of animal test demonstrated that longistyline C had the antidepressant activity, which the effect is similar to the positive control. In current study, we investigated the effect of longistyline C on glutamate-induced injury in PC12 cells and explored its possible signaling pathways. The results demonstrated that pretreatment with longistyline C at the concentrations of 2-8 μmol/L for 24 h had a significant reduction of the cytotoxicity induced by glutamate (15 mmol/L) in PC12 cells using MTT, lactate dehydrogenase (LDH) release assay and Annexin V-PI double staining. Subsequently, we found that pretreatment with longistyline C (8 μmol/L) could drastically down-regulate the over-expression of NMDAR/NR2B and Ca2+/calmodulin-dependent protein kinase II (CaMKII), up-regulate the expressions of p-ERK and p-CREB and alleviate ER stress. In conclusison, longistyline C is most possibly through regulating NMDAR/NR2B-ERK1/2 related pathway and restoring endoplasmic reticulum function to exert neuroprotective effect against glutamate-induced injury in PC12 cells.
