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

Apurinic/apyrimidinic endonuclease 1/redox factor-1 (APE1) protects cells from oxidative stress via the base excision repair pathway and as a redox transcriptional coactivator. It is required for tumor progression/metastasis, and its up-regulation is associated with cancer resistance. Loss of APE1 expression causes cell growth arrest, mitochondrial impairment, apoptosis, and alterations of the intracellular redox state and cytoskeletal structure. A detailed knowledge of the molecular mechanisms regulating its different activities is required to understand the APE1 function associated with cancer development and for targeting this protein in cancer therapy. To dissect these activities, we performed reconstitution experiments by using wild-type and various APE1 mutants. Our results suggest that the redox function is responsible for cell proliferation through the involvement of Cys-65 in mediating APE1 localization within mitochondria. C65S behaves as a loss-of-function mutation by affecting the in vivo folding of the protein and by causing a reduced accumulation in the intermembrane space of mitochondria, where the import protein Mia40 specifically interacts with APE1. Treatment of cells with (E)-3-(2-[5,6-dimethoxy-3-methyl-1,4-benzoquinonyl])-2-nonyl propenoic acid, a specific inhibitor of APE1 redox function through increased Cys-65 oxidation, confirm that Cys-65 controls APE1 subcellular trafficking and provides the basis for a new role for this residue.
