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

backgroundHepatocellular carcinoma (HCC) is a lethal malignancy characterized by profound metabolic reprogramming, notably aberrant lipid metabolism. Current therapeutic strategies offer limited efficacy, highlighting the critical need to identify its metabolic vulnerabilities. This study aims to investigate the role of the HKDC1-ASS1-ACSBG2 axis in lipid metabolic reprogramming and therapeutic resistance in HCC.

methodsUsing clinical HCC specimens and cell lines, we systematically evaluated the functions and mechanisms of HKDC1, ASS1, and ACSBG2 in lipogenesis, cell proliferation, and drug response via RNA sequencing, co-immunoprecipitation, immunofluorescence, ubiquitination assays, dual-luciferase reporter assays, cellular functional experiments, and nude mouse xenograft models.

resultsHKDC1 was highly expressed in HCC and correlated with poor patient prognosis. Mechanistically, HKDC1 interacts with ASS1 (310–412 aa) via its HKLS1 domain, inhibiting ubiquitin-mediated degradation and stabilizing ASS1. This enhances the production of glutamine-derived acetyl-CoA. The accumulated acetyl-CoA transcriptionally activates ACSBG2 by inducing histone H3 acetylation, thereby driving lipid biosynthesis and HCC cell proliferation. This axis operates distinctly from the FASN-dependent pathway and promotes lenvatinib resistance both in vitro and in vivo.

conclusionOur study unveils a novel metabolic regulatory axis, HKDC1-ASS1-ACSBG2, that promotes lipogenesis and tumor progression in HCC by integrating multiple metabolic pathways, and confers lenvatinib resistance. Targeting this axis may present a novel therapeutic strategy to overcome treatment resistance in this recalcitrant malignancy.
