Senegenin Inhibits Hypoxia/Reoxygenation-Induced Neuronal Apoptosis by Upregulating RhoGDIα.
Article in Molecular neurobiology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
Neuronal apoptosis is an important event in hypoxia/reoxygenation (H/R)-induced neuronal injury. Senegenin (Sen), the predominant and most active component in Radix Polygalae root extracts, displays anti-apoptotic and anti-oxidative properties. Sen protects against H/R-induced neuronal apoptosis of highly differentiated PC12 cells and primary cortical neurons. Sen has also been investigated as a source of potential therapeutic targets. In this study, a proteomic approach was used to identify Sen-regulated proteins in PC12 cells. We found that Sen protected against H/R-induced neuronal apoptosis by upregulating RhoGDIα protein expression. The regulatory functions of RhoGDIα were investigated by knocking down RhoGDIα expression in PC12 cells using small interfering RNA (siRNA), followed by quantification of apoptosis and then altering the expression levels of apoptosis-related proteins. Our data show that after silencing RhoGDIα, the neuroprotective effects of Sen on H/R-induced PC12 cell apoptosis were absent. Furthermore, RhoGDIα silencing alleviated the Sen-mediated inhibition of the JNK pathway. Therefore, these findings indicated that Sen attenuates H/R-induced neuronal apoptosis by upregulating RhoGDIα expression and inhibiting the JNK pathway. In addition to the mechanism underlying neuroprotective effects of Sen, RhoGDIα was identified as a putative target of Sen based on a primary rat cortical neuron model of H/R-induced injury.
