1 · What the graph read from it

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.

2 · The registry

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

Although many advances have been made in the pathogenesis of epilepsy recently, the pathological mechanisms of epilepsy are still largely unknown. Exploring the pathological mechanisms and developing novel therapeutic strategies for epilepsy are urgently needed. A SD rat model of epilepsy was established with lithium chloride-pilocarpine. Astrocytes were isolated, cultured from 8 to 12 week rats and identified by flow cytometry and immunofluorescence. Immunohistochemical staining was used for MEF2C and NF-κB in paraffin-embedded sections. RT-qPCR and western blot were used to analyze gene expression. ELISA was used to analyze the concentration of IL-6, TNF-α and Cox-2. Cells were transfected with pcDNA-MEFC2, sh-MEFC2, pcDNA-UCA1, sh-UCA1, miR-203 mimic or miR-203 inhibitor. Cell viability was assessed by MTT assay. Dual luciferase assay was used to determine the direct interaction of lncRNA UCA1/miR-203 and miR-203/MEF2C. MEF2C was down-regulated and inhibited NF-κB expression and the secretion of IL-6 and TNF-α in epilepsy. LncRNA UCA1 was also down-regulated in epilepsy. LncRNA UCA1 over-expression increased the expression of MEF2C and its knock-down decreased MEF2C expression. Luciferase activity showed lncRNA UCA1 directly targeted miR-203 and miR-203 directly targeted MEF2C. MiR-203 suppressed the expression of MEF2C, and promoted NF-κB, phosphorylated IκB/IKK and inflammatory effectors, which was reversed by MEF2C knock-down. Moreover, lncRNA UCA1 could increase the expression of MEF2C to inhibit NF-κB, phosphorylated IκB/IKK and inflammatory effectors, which was also reversed by miR-203 mimic transfection. LncRNA UCA1 inhibited the inflammation via regulating miR-203 mediated regulation of MEF2C/NF-κB signaling in epilepsy. Our investigation elucidated novel pathological mechanisms and provided potential therapeutic targets for epilepsy.
