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

introductionMethamphetamine (METH) is a psychostimulant drug with complicated neurotoxicity, and abuse of METH is very common. Studies have shown that METH exposure causes alpha-synuclein (α-syn) accumulation. However, the mechanism of α-syn accumulation has not been determined.

methodsIn this study, we established cell and animal models of METH intoxication to evaluate how METH affects α-syn expression. In addition, to explore METH-induced neurotoxicity, we measured the level of Parkin and the phosphorylation levels of α-syn, Polo-like kinase 2 (PLK2), the proteasome activity marker CD3δ, and the apoptosis-related proteins Caspase-3 and PARP. Parkin is a key enzyme in the ubiquitin-proteasome system. In addition, the effect of Parkin on METH-induced neurotoxicity was investigated by overexpressing it in vitro and in vivo.

resultsMETH exposure increased polyubiquitin and α-syn expression, as did MG132. Furthermore, the level of Parkin and the interaction between Parkin and α-syn decreased after METH exposure. Importantly, the increases in α-syn expression and neurotoxicity were relieved by Parkin overexpression.

conclusionsBy establishing stable cell lines and animal models that overexpress Parkin, we confirmed Parkin as an important factor in METH-induced α-syn degradation dysfunction in vitro and in vivo. Parkin may be a promising target for the treatment of METH-induced neurotoxicity.
