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

RNA helicase DHX9 is a multi-functional protein governing transcriptional modulation, RNA processing, R-loop balance, and genome stability. SUMOylation is a post-translational modification that adds a critical regulatory layer to protein function by diversifying subcellular localization, stability, enzymatic activity, and protein-protein interactions. This protocol describes a basic but detailed approach for the analysis of DHX9 SUMOylation. We demonstrate that accurate site identification, specifically at Lysine 120 (K120), is the prerequisite for defining the molecular mechanism of this modification. Identifying the K120 acceptor site enables the generation of specific mutants to dissect how DHX9 SUMOylation orchestrates the protein interactions necessary to preserve genomic integrity. Furthermore, this protocol provides a versatile framework for characterizing the SUMOylation of other RNA helicases involved in RNA regulation.
