CDDO-Me Attenuates Vasogenic Edema and Astroglial Death by Regulating NF-κB p65 Phosphorylations and Nrf2 Expression Following Status Epilepticus.
Article in International journal of molecular sciences, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
2-Cyano-3,12-dioxo-oleana-1,9(11)-dien-28-oic acid methyl ester (CDDO-Me) is a triterpenoid analogue of oleanolic acid that has anti-inflammatory, antioxidant, and neuroprotective activities. In the present study, we evaluate the effects of CDDO-Me on serum extravasation and astroglial death in the rat piriform cortex (PC) induced by status epilepticus (a prolonged seizure activity, SE) in order to propose an underlying pharmacological mechanism of CDDO-Me and its availability for treatment of vasogenic edema. CDDO-Me effectively mitigated serum extravasation and a massive astroglial loss in the PC following SE. CDDO-Me abrogated tumor necrosis factor-α (TNF-α) synthesis in activated microglia by inhibiting nuclear factor-κB (NF-κB) p65 serine 276 phosphorylation. CDDO-Me also abolished NF-κB threonine 435 phosphorylation in endothelial cells and TNF-α-mediated-phosphatidylinositol-3-kinase (PI3K)/AKT/endothelial nitric oxide synthase (eNOS) signaling cascades, which trigger vasogenic edema following SE. Furthermore, CDDO-Me increased astroglial viability via the up-regulation of nuclear factor-erythroid 2-related factor 2 (Nrf2) expression. Therefore, our findings suggest that CDDO-Me may ameliorate SE-induced vasogenic edema formation by regulating NF-κB p65 phosphorylations in microglia as well as endothelial cells and enhancing Nrf2 expression in astrocytes, respectively.
