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

Oxidative stress mediates the pathogenesis of neurodegenerative disorders. Gartanin, a natural xanthone of mangosteen, possesses multipharmacological activities. Herein, the neuroprotection capacity of gartanin against glutamate-induced damage in HT22 cells and its possible mechanism(s) were investigated for the first time. Glutamate resulted in cell death in a dose-dependent manner and supplementation of 1-10 µM gartanin prevented the detrimental effects of glutamate on cell survival. Additional investigations on the underlying mechanisms suggested that gartanin could effectively reduce glutamate-induced intracellular ROS generation and mitochondrial depolarization. We further found that gartanin induced HO-1 expression independent of nuclear factor erythroid-derived 2-like 2 (Nrf2). Subsequent studies revealed that the inhibitory effects of gartanin on glutamate-induced apoptosis were partially blocked by small interfering RNA-mediated knockdown of HO-1. Finally, the protein expression of phosphorylation of AMP-activated protein kinase (AMPK) and its downstream signal molecules, Sirtuin activator (SIRT1) and peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α), increased after gartanin treatment. Taken together, these findings suggest gartanin is a potential neuroprotective agent against glutamate-induced oxidative injury partially through increasing Nrf-2-independed HO-1 and AMPK/SIRT1/PGC-1α signaling pathways.
