Glycine: The missing link between carbohydrate and xenobiotic metabolism in the maturing human hepatocyte.
Article in iScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Modulation of cellular metabolism is crucial in pluripotent stem cell (PSC) development and differentiation. Glycine was shown to promote liver cell maturation, boosting Cytochrome P450 (CYP) isoform 3A4 activity, a key enzyme in phase I metabolism. This study examines the remodeling of central and xenobiotic metabolism during the glycine-supplemented differentiation of induced PSCs (iPSCs) into hepatocyte-like cells (HLCs) and HepG2 into a metabolically active form (mHepG2). In these cell systems, glycine promoted oxidative metabolism and mitochondrial function, collagen, glycogen, bile acid anabolism, one-carbon metabolism, and heme biosynthesis, typical of a hepatocyte phenotype. While the metabolic effects of glycine were divergent in mHepG2 and HLCs, in both cases, heme synthesis was boosted by glycine incorporation, a vital feature in supporting xenobiotic metabolism through the heme-containing enzymes CYPs. From this study, a link between glycine supplementation, carbohydrate metabolism, and enhancement of the xenobiotic machinery is established through metabolic plasticity in the maturing hepatocyte.
