Abstract

The progression of chronic liver disease to hepatocellular carcinoma is caused by the acquisition of somatic mutations that affect 20-30 cancer genes 1-8. Burdens of somatic mutations are higher and clonal expansions larger in chronic liver disease 9-13 than in normal liver 13-16, which enables positive selection to shape the genomic landscape 9-13. Here we analysed somatic mutations from 1,590 genomes across 34 liver samples, including healthy controls, alcohol-related liver disease and non-alcoholic fatty liver disease. Seven of the 29 patients with liver disease had mutations in FOXO1, the major transcription factor in insulin signalling. These mutations affected a single hotspot within the gene, impairing the insulin-mediated nuclear export of FOXO1. Notably, six of the seven patients with FOXO1 S22W hotspot mutations showed convergent evolution, with variants acquired independently by up to nine distinct hepatocyte clones per patient. CIDEB, which regulates lipid droplet metabolism in hepatocytes 17-19, and GPAM, which produces storage triacylglycerol from free fatty acids 20,21, also had a significant excess of mutations. We again observed frequent convergent evolution: up to fourteen independent clones per patient with CIDEB mutations and up to seven clones per patient with GPAM mutations. Mutations in metabolism genes were distributed across multiple anatomical segments of the liver, increased clone size and were seen in both alcohol-related liver disease and non-alcoholic fatty liver disease, but rarely in hepatocellular carcinoma. Master regulators of metabolic pathways are a frequent target of convergent somatic mutation in alcohol-related and non-alcoholic fatty liver disease.

  • In NASH livers, convergent mutations were identified in genes central to insulin signaling and lipogenesis.

    “In NASH livers, Ng et. al. identified convergent mutations in genes central to insulin signaling and lipogenesis6.”

    From Positive selection of somatically mutated clones identifies adaptive pathways in metabolic liver disease (2023) · cites this paper as [6]

    The indexed Abstract reports independently arising mutations in FOXO1, a gene involved in insulin signalling, and GPAM, which produces storage triacylglycerol. It describes samples from patients with non-alcoholic fatty liver disease, but does not establish that these findings were specifically in NASH livers; the NASH qualifier is unsupported.

  • TP53 and CTNNB1 mutations do not drive extensive clonal expansion events before tumor initiation.

    “The HCC driver genes TP53 (tumor protein p53) and CTNNB1 (catenin beta 1) are not the most frequently observed mutant genes in the cirrhotic liver (7–9), suggesting that these mutations do not drive extensive clonal expansion events before tumor initiation.”

    From The origin of hepatocellular carcinoma depends on metabolic zonation (2026) · cites this paper as [9]

    No passage from our copy addresses whether TP53 or CTNNB1 mutations drive extensive clonal expansion before tumor initiation. Searches for both genes and for clonal expansion in cirrhotic liver returned no relevant passage, so the claim cannot be assessed from the available evidence. (LLM, conf=0.70)

    Experimental — accuracy not yet measured
  • After decades of injury, cirrhotic livers consist of millions of nodules, most of which harbor somatic mutations.

    “After decades of injury, cirrhotic livers consist of millions of nodules, most of which harbor somatic mutations (7–9).”

    From The origin of hepatocellular carcinoma depends on metabolic zonation (2026) · cites this paper as [9]

    No passage from our copy addresses whether cirrhotic livers contain millions of nodules or whether most nodules harbor somatic mutations. Searches for nodules, millions, cirrhosis, and somatic mutations found no relevant passage. (LLM, conf=0.72)

    No passage from our copy addresses whether TP53 and CTNNB1 are among the most frequently mutated genes in cirrhotic liver. Searches for both gene names and for mutations in cirrhosis returned only bibliographic material, with no findings or page-level evidence to assess the claim. (LLM, conf=0.70)

  • The inefficient CreER recombination faithfully modeled the somatic mosaicism seen in human livers before cancer development.

    “While this showed that CreER was not 100% efficient, it also faithfully modeled the somatic mosaicism seen in human livers before cancer development (7–9, 33).”

    From The origin of hepatocellular carcinoma depends on metabolic zonation (2026) · cites this paper as [9]

    The supplied passage contains only the paper’s title and author information (no section or page). Searches for somatic mosaicism, CreER recombination, and hepatocyte clones found no eligible passage in our copy establishing that inefficient CreER recombination faithfully models mosaicism in human livers before cancer development.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
