Protodioscin protects PC12 cells against oxygen and glucose deprivation-induced injury through miR-124/AKT/Nrf2 pathway.

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
The purpose of the current study was to demonstrate the neuroprotective effect of protodioscin (Prot) in an in vitro model of ischemia/reperfusion (I/R) and investigate the underlying molecular mechanism. After PC12 cells were exposed to oxygen and glucose deprivation (OGD) reperfusion, PI staining by flow cytometry was used to quantify the rate of apoptosis. The levels of hypoxia-inducible factor 1-alpha (HIF-1α), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and malondialdehyde (MDA) were determined using commercially available kits. Intracellular reactive oxygen species (ROS) level was detected using the 20,70-dichlorodihy-drofluorescein diacetate (DCFH-DA) fluorescence assay. The expression levels of heat-shock proteins (HSP), PI3K, AKT, Nrf2, and miR-124 were tested by western blot or quantitative PCR. Prot significantly attenuated oxygen-glucose deprivation/reperfusion (OGD/R)-induced apoptotic death. Prot also reduced the oxidative stress as revealed by increasing the activities of SOD and GSH-Px, decreasing the levels of ROS and MDA. Moreover, mechanism investigations suggested that Prot prevented the decrease of HSP70, HSP32 (hemeoxygenase-1, HO-1), and PI3K protein expression, phosphorylation of AKT, and the accumulation of nuclear Nrf2. The level of miR-124 was decreased in PC12 cells, which was also effectively reversed by Prot treatment. Prot protected PC12 cells against OGD/R-induced injury through inhibiting oxidative stress and apoptosis, which could be associated with increasing HSP proteins expression via activating PI3K/AKT/Nrf2 pathway and miR-124 modulation.
