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

Sequential metabolic enzymes have long been hypothesized to form multienzyme metabolic complexes to regulate metabolic flux in cells. Although in vitro biochemistry has not been fruitful to support the hypothesis, advanced biophysical technologies have successfully resurrected the hypothesis with compelling experimental evidence. As biochemistry has always evolved along with technological advancement over the century (e.g., recombinant protein expression, site-directed mutagenesis, advanced spectroscopy and structural biology techniques, etc.), there has been growing interest in advanced imaging-based biophysical methods to explore enzymes inside living cells. In this work, we describe how we visualize two phase-separated biomolecular condensates of multienzyme metabolic complexes that are associated with de novo purine biosynthesis and glucose metabolism in living human cells and how imaging-based data are quantitatively analyzed to advance our knowledge of enzymes and their assemblies in living cells. Therefore, we envision that the framework we describe here would be the starting point to investigate other metabolic enzymes and their assemblies in various cell types with an unprecedented potential to comprehend enzymes and their network in native habitats.
