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

O-Linked N-acetylglucosamine (O-GlcNAc) is a nucleocytoplasmic post-translational modification that is tightly regulated by O-GlcNAc transferase (OGT) and O-GlcNAcase (OGA). Dysregulation of O-GlcNAc in human disease has motivated efforts to therapeutically modulate O-GlcNAc. Drug repurposing efforts can accelerate these campaigns and unveil how clinically relevant compounds and pathways intersect with O-GlcNAc. Here we report the results of three parallel drug repurposing screens against the O-GlcNAc cycling enzymes in cells and in vitro that reveal kinase inhibitors GSK690693 and Y-33075 act as splicing modulators that disrupt O-GlcNAc homeostasis and simultaneously downregulate OGT and OGA. These effects are independent of their respective annotated targets, AKT and ROCK, and are distinct from OGT and OGA inhibitors and similar kinase inhibitors. Evaluation of a panel of splicing modulators revealed three additional potent compounds (OTS964, indisulam, GNF2133) that similarly downregulate OGT and OGA with distinct splicing profiles. These findings reveal previously unobserved splicing modulator chemotypes and approaches to disrupt O-GlcNAc homeostasis.
