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

Alcohol-associated liver disease (ALD) remains a major public health challenge with limited treatment options. NF-κB-driven inflammation in Kupffer cells (KCs) plays a central role in ALD, but the upstream regulators remain poorly understood. Here, we identify the tyrosine kinase SRC as a key mediator of ALD. Chronic ethanol exposure activates SRC in KCs, which directly phosphorylates ubiquitin-conjugating enzyme 9 (UBC9), the only E2 SUMO enzyme, at tyrosine-68 (Y68). This modification enhances NF-κB signaling and increases proinflammatory cytokines (TNF-α, IL-6, and IL-1β). These cytokines then promote hepatic lipogenesis through SREBP1c- and CEBPβ-dependent induction of FASN and ACC. Inhibition of UBC9 phosphorylation by gene editing or SRC inhibitor reduces NF-κB-dependent inflammation and lessens ethanol-induced liver injury in mouse models. These findings uncover a previously unrecognized SRC-UBC9-NF-κB axis that drives inflammation in ALD and highlight it as a potential therapeutic target in liver disease.
