Evaluation of the protective potential of brain microvascular endothelial cell autophagy on blood-brain barrier integrity during experimental cerebral ischemia-reperfusion injury.

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
Brain microvascular endothelial cell (BMVEC) injury induced by ischemia-reperfusion (I/R) is the initial phase of blood-brain barrier (BBB) disruption, which results in a poor prognosis for ischemic stroke patients. Autophagy occurs in ischemic brain and has been shown to exhibit protective effects on endothelial cell against stress. However, the potential effects of BMVEC autophagy on BBB permeability during I/R and the mechanisms underlying these effects have yet to be elucidated. In the current study, we answered these questions by using chemical modulators of autophagy, including rapamycin and lithium carbonate acting, respectively, as mammalian target of rapamycin (mTOR)-dependent and mTOR-independent autophagy inducers and 3-methyladenine (3-MA) as an autophagy inhibitor. To mimic I/R injury, BMVECs were exposed to oxygen-glucose deprivation/reoxygenation (OGD/R), and a rat transient middle cerebral artery occlusion/reperfusion (MCAO/R) model was performed. All the drugs were given at 0.5 h before OGD/R or MCAO/R. First, enhancement of autophagy by rapamycin and lithium carbonate attenuated, whereas suppression of autophagy by 3-MA intensified BMVEC apoptosis and the high level of ROS induced by OGD/R. In addition, rapamycin and lithium carbonate pretreatments significantly reversed the decreased level of tight junction protein zonula occludens-1 (ZO-1) induced by OGD/R and promoted the distribution of ZO-1 on cell membranes. Finally, pretreatments with rapamycin and lithium carbonate reduced evans blue extravasation and brain water content in the ischemic hemisphere of the rat. In contrast, 3-MA pretreatment exerted opposite effects both in vitro and in vivo. These results may indicate a beneficial effect of BMVEC autophagy on BBB integrity during I/R injury.
