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

Protein O-GlcNAcylation is a dynamic post-translational modification with emerging roles in cardiac pathophysiology. The availability of different pan-specific antibodies to assess global O-GlcNAc levels, and variability in western blot results has hindered cross-study reproducibility and interpretation. In this study, we applied optimized immunoblotting protocols using both CTD110.6 and RL2 O-GlcNAc antibodies, alongside subcellular fractionation, to investigate temporal and sex-specific changes in cardiac O-GlcNAcylation during pressure overload hypertrophy (POH) from transverse aortic constriction (TAC) during early (1-week POH, 1wTAC) and chronic (6-weeks POH, 6wTAC) POH in mice. Global O-GlcNAc levels were elevated in early POH and returned to baseline in chronic POH, consistent across both antibodies and sexes. Subcellular fractionation revealed persistent O-GlcNAc elevations in cytoplasmic and membrane fractions in chronic POH for both sexes, which were not detected in unfractionated samples. Female mice exhibited significantly higher O-GlcNAc levels than males during POH, particularly at early POH, highlighting sex-specific regulation. OGT and OGA protein levels also varied by compartment and sex, suggesting differential enzymatic control. In conclusion, our findings underscore the importance of methodological rigor in O-GlcNAc detection and demonstrate that fractionation enhances sensitivity to subtle changes in cardiac O-GlcNAcylation. Our principal new findings are protein O-GlcNAcylation dysregulation continues from early POH (1wTAC) into chronic POH (6wTAC groups) along with showing differences in O-GlcNAc levels between males and females during POH. These results provide new insights into the temporal and sex-dependent dynamics of O-GlcNAc signaling in POH and support its potential as a therapeutic target in cardiovascular disease.
