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

Methylglyoxal (MGO) and glyoxal (GO) are reactive carbonyl species (RCS) generated as side products in glycolysis and carbohydrate, protein, and fat catabolism, which are enriched in most cancer cells. MGO/GO-induced nonenzymatic glycation on histones plays pathophysiologically important roles in regulating the three-dimensional architecture of cellular chromatin and cancer development. In our previous studies, we have uncovered that enzymes DJ-1 and PAD4 exhibit "glyoxalase" and "deglycase" activities to antagonize the MGO/GO-modifications of histones. We also found that the general inhibition of histone deacetylases using suberoylanilide hydroxamic acid (SAHA) antagonized histone MGO-glycation due to the direct competition of reactive sites (i.e., lysine residues). Here, we report that a histone deacetylase, sirtuin 2 (SIRT2), functions as a "semi-deglycase" that removes lactic and glycolic acids from ε-
