GCN5 drives MASLD progression through LXRα/SREBP1c signaling pathway-mediated de novo lipogenesis.

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
Metabolic dysfunction-associated steatotic liver disease (MASLD) is a global health concern that affects nearly one-quarter of the world's population. General control non-repressed protein 5 (GCN5), a histone acetyltransferase (HAT), has been implicated in the progression of several diseases, but its role in MASLD remains unclear. Here, we provide the experimental evidence that progressive human and male murine MASLD is driven by GCN5, but not by p300/CREB binding protein associated factor (PCAF) activation. Hepatocyte-specific GCN5 overexpression accelerates MASLD progression, whereas its ablation alleviates disease severity. Moreover, pharmacological inhibition of GCN5 with CPTH2 protects against MASLD. Metabolomics and RNA-seq analyses demonstrate that GCN5 promotes de novo lipogenesis (DNL) by upregulating SREBP1c-mediated transcription of lipogenic genes. Mechanistically, GCN5 acetylates histone H3 at the SREBP1c promoter, enhancing transcription through its intrinsic acetyltransferase activity. Our findings further identify GCN5 as a key regulator of LXRα-induced SREBP1c expression, suggesting that targeting GCN5 may selectively inhibit SREBP1c-driven DNL without impairing LXRα-mediated reverse cholesterol transport (RCT). Notably, combined treatment with the Liver X Receptor (LXR) agonist T0901317 and CPTH2 synergistically reduced lipid accumulation in vitro and in vivo, highlighting a promising therapeutic strategy for MASLD.
