Correlating metabolites, lipids, and N-glycans in murine kidney microstructures via integrative mass spectrometry imaging.
Article in Nature communications, 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
Understanding how metabolites, lipids and glycans interact within tissues at the same cellular layer is key to uncovering their roles in health and disease. Herein, we present an integrative multi-omic mass spectrometry imaging (MSI) approach correlating metabolites, lipids and N-glycans, including their linkage-specific sialic acid information, in a single renal tissue section. Our protocol enables the sequential detection of hundreds of metabolites and lipids species alongside diverse glycosylation traits in small cell clusters across the kidney. Importantly, our pixel-to-pixel co-registration and clustering correlates glycans (recorded in positive mode MS), metabolites, and lipids (both in negative mode MS) across kidney microstructures. This analysis reveals strong association between taurine, TCA metabolites, sulfatides, and polyunsaturated phospholipids, and specific sialic acid linkages on N-glycans in the thick ascending limb and collecting ducts. The robust strategy maximizes molecular insights from scarcely available samples and offers a powerful tool for exploring tissue complexity in both normal and disease states.
