Proteomic analysis of primary cultured rat cortical neurons in chemical ischemia.
Article in Neurochemical research, 2013. 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
To elucidate the molecular events involved in early ischemic neuronal death, we performed two-dimensional proteome profiling of primary cultures of rat cortical neurons following chemical ischemia induced by the administration of sodium azide under glucose-free conditions. Using a lactic dehydrogenase assay and Western blot analysis of dephosporylation of the voltage-gated potassium channel Kv2.1, we determined duration of chemical ischemia of 2 h to be the relevant time-point for early ischemic neuronal death. Sixty-one proteins were differentially expressed, and 26 different proteins were identified by MALDI-TOF with Mascot database searching. The proteome data indicated that chemical ischemia altered the expression of 20 proteins that are involved in stress response/chaperone, brain development, cytoskeletal/structural proteins, metabolic enzymes, and calcium ion homeostasis. Western blotting and immunocytochemical studies of the 6-most functionally significant proteins showed that, in the ischemia-treated group, the expression of glucose-related protein 78, heat shock protein 90 alpha, and α-enolase was significantly increased, while the expression of inositol triphosphate receptor 1 and ATP synthase beta subunit was decreased. In addition, the expression of dihydropyrimidinase-like 3 showed a truncated pattern in the ischemia group. The changes in the expression of these proteins might be significant indicators of early ischemic neuronal death.
