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

The objective of this research was to investigate the role of lncRNA MALAT1 and HSP90 in the regulation of neuronal necroptosis in mice with cerebral ischemia-reperfusion (CIR). We used male C57BL/6J mice to establish a middle cerebral artery occlusion (MCAO) model and conducted in vitro experiments using the HT-22 mouse hippocampal neuron cell line. The cellular localization of NeuN and MLKL, as well as the expression levels of neuronal necroptosis factors, MALAT1, and HSP90 were analyzed. Cell viability and necroptosis were assessed, and we also investigated the relationship between MALAT1 and HSP90. The results showed that MALAT1 expression increased after MCAO and oxygen-glucose deprivation/re-oxygenation (OGD/R) treatment in both cerebral tissues and cells compared with the control group. The levels of neuronal necroptosis factors and the co-localization of NeuN and MLKL were also increased in MCAO mice compared with the Sham group. MALAT1 was found to interact with HSP90, and inhibition of HSP90 expression led to decreased phosphorylation levels of neuronal necroptosis factors. Inhibition of MALAT1 expression resulted in decreased co-localization levels of NeuN and MLKL, decreased phosphorylation levels of neuronal necroptosis factors, and reduced necroptosis rate in cerebral tissues. Furthermore, inhibiting MALAT1 expression also led to a shorter half-life of HSP90, increased ubiquitination level, and decreased phosphorylation levels of neuronal necroptosis factors in cells. In conclusion, this study demonstrated that lncRNA MALAT1 promotes neuronal necroptosis in CIR mice by stabilizing HSP90.
