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

backgroundTaurine is a free amino acid present in high concentrations in a variety of organs of mammalians. As an antioxidant, taurine has been found to protect cells against oxidative stress, but the underlying mechanism is still unclear.

methodsIn this report, we present evidence to support the conclusion that taurine exerts a protective function against endoplasmic reticulum (ER) stress induced by H2O2 in PC 12 cells. Oxidative stress was introduced by exposure of PC 12 cells to 250 uM H2O2 for 4 hours.

resultsIt was found that the cell viability of PC 12 cells decreased with an increase of H2O2 concentration ranging from approximately 76% cell viability at 100 uM H2O2 down to 18% at 500 uM H2O2. At 250 uM H2O2, cell viability was restored to 80% by taurine at 25 mM. Furthermore, H2O2 treatment also caused a marked reduction in the expression of Bcl-2 while no significant change of Bax was observed. Treatment with taurine restored the reduced expression of Bcl-2 close to the control level without any obvious effect on Bax. Furthermore, taurine was also found to suppress up-regulation of GRP78, GADD153/CHOP and Bim induced by H2O2, suggesting that taurine may also exert a protective function against oxidative stress by reducing the ER stress.

conclusionIn summary, taurine was shown to protect PC12 cells against oxidative stress induced by H2O2. ER stress was induced by oxidative stress and can be suppressed by taurine.
