NCAM140 and pCREB Expression after Tianeptine Treatment of SH-SY5Y Cells.
Article in Psychiatry investigation, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveAntidepressants Modulate Neuronal Plasticity. Tianeptine, An Atypical Antidepressant, Might Be Involved In The Restoration Of Neuronal Plasticity; It Primarily Enhances The Synaptic Reuptake Of Serotonin. Ncam140 Is Involved In Neuronal Development Processes, Synaptogenesis And Synaptic Plasticity. We Investigated The Effect Of Tianeptine On The Expression Of Ncam140 And Its Downstream Signaling Molecule In The Human Neuroblastoma Cell Line Sh-sy5y.
methodsNCAM protein expression was measured in human neuroblastoma SH-SY5Y cells that were cultivated in serum-free media and treated with 0, 10, or 20 µM tianeptine for 6, 24, or 72 hours. NCAM140 expression in the tianeptine treatment group was confirmed by Western blot, and quantified through measurement of band intensity by absorbance. CREB and pCREB expression was identified after treatment with 20 µM tianeptine for 6, 24, and 72 hours by Western blot.
resultsCompared to cells treated for 6 hours, cells treated with 0 or 10 µM tianeptine for 72 hours showed a significant increase in NCAM140 expression and cells treated with 20 µM tianeptine showed a significant increase after 24 and 72 hours. The pCREB level in cells treated with 20 µM tianeptine increased in time-dependent manner.
conclusionOur findings indicated that the tianeptine antidepressant effect may occur by induction of NCAM140 expression and CREB phosphorylation.
