Propofol protects PC12 cells from cobalt chloride-induced injury by mediating miR-134.
Article in Histology and histopathology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivePropofol (PRO) was reported to exert a neuroprotective effect by decreasing microRNA-134 (miR-134), a brain-specific miRNA, thus, the role of PRO against cobalt chloride (CoCl₂)-induced injury in rat pheochromocytoma cells (PC12) via mediating miR-134 was explored.
methodsCoCl₂-induced PC12 cells treated with PRO were transfected with or without miR-134 negative control (NC)/ inhibitor/mimic, and the following detections were then performed using cell counting kit-8 (CCK-8), Annexin V-fluorescein isothiocyanate/propidium iodide (Annexin V-FITC/PI) and Hoechst 33258 staining. Autophagy was observed by transmission electron microscope (TEM). Mitochondrial membrane potential (MMP) was detected by Rhodamine-123 (Rh123) staining, and reactive oxygen species (ROS) by dichloro-dihydro-fluorescein diacetate (DCFH-DA) staining. Protein and gene expressions were measured by Western blotting and quantitative reverse transcriptase polymerase chain reaction (qRT-PCR), respectively.
resultsPRO reversed the CoCl₂-induced decrease in the PC12 cell viability and increased miR-134 in a dose-dependent manner. CoCl₂ increased LC3II/I ratio and Beclin-1 expression, but decreased p62 expression, which was abolished by PRO. In addition, an increased cell apoptosis rates triggered by CoCl₂ were reduced by PRO with the down-regulations of Bax and Caspase-3 and the up-regulation of Bcl-2. Furthermore, PRO decreased methylenedioxyamphetamine (MDA), nitric oxide (NO) and ROS in CoCl₂-induced PC12 cells accompanying the increase in glutathione peroxidase (GSH-Px) and MMP. The effects of PRO on autophagy, apoptosis and oxidative stress in CoCl₂-induced PC12 cell were reversed by miR-134 mimic.
conclusionPRO may mitigate CoCl₂-induced autophagy in PC12 cells with decreased apoptosis and improved oxidative stress via mediating miR-134.
