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

Sub-lethal activation of cell death processes initiate pro-survival signaling cascades. As intracellular Zn(2+) liberation mediates neuronal death pathways, we tested whether a sub-lethal increase in free Zn(2+) could also trigger neuroprotection. Neuronal free Zn(2+) transiently increased following preconditioning, and was both necessary and sufficient for conferring excitotoxic tolerance. Lethal exposure to NMDA led to a delayed increase in Zn(2+) that contributed significantly to excitotoxicity in non-preconditioned neurons, but not in tolerant neurons, unless preconditioning-induced free Zn(2+) was chelated. Thus, preconditioning may trigger the expression of Zn(2+)-regulating processes, which, in turn, prevent subsequent Zn(2+)-mediated toxicity. Indeed, preconditioning increased Zn(2+)-regulated gene expression in neurons. Examination of the molecular signaling mechanism leading to this early Zn(2+) signal revealed a critical role for protein kinase C (PKC) activity, suggesting that PKC may act directly on the intracellular source of Zn(2+). We identified a conserved PKC phosphorylation site at serine-32 (S32) of metallothionein (MT) that was important in modulating Zn(2+)-regulated gene expression and conferring excitotoxic tolerance. Importantly, we observed increased PKC-induced serine phosphorylation in immunopurified MT1, but not in mutant MT1(S32A). These results indicate that neuronal Zn(2+) serves as an important, highly regulated signaling component responsible for the initiation of a neuroprotective pathway.
