Abstract

Adult hepatocyte identity is constructed throughout embryonic development and fine-tuned after birth. A multinodular network of transcription factors, along with pre-mRNA splicing regulators, define the transcriptome, which encodes the proteins needed to perform the complex metabolic and secretory functions of the mature liver. Transient hepatocellular dedifferentiation can occur as part of the regenerative mechanisms triggered in response to acute liver injury. However, persistent downregulation of key identity genes is now accepted as a strong determinant of organ dysfunction in chronic liver disease, a major global health burden. Therefore, the identification of core transcription factors and splicing regulators that preserve hepatocellular phenotype, and a thorough understanding of how these networks become disrupted in diseased hepatocytes, is of high clinical relevance. In this context, we review the key players in liver differentiation and discuss in detail critical factors, such as HNF4α, whose impairment mediates the breakdown of liver function. Moreover, we present compelling experimental evidence demonstrating that restoration of core transcription factor expression in a chronically injured liver can reset hepatocellular identity, improve function and ameliorate structural abnormalities. The possibility of correcting the phenotype of severely damaged and malfunctional livers may reveal new therapeutic opportunities for individuals with cirrhosis and advanced liver disease.

  • Breakdown in liver functions in advanced stages of liver injuries and in cancer results from hepatocyte loss of identity stemming from compromised expression of the hepatic core transcriptional regulatory circuitry transcription factors.

    “breakdown in liver functions in advanced stages of liver injuries and in cancer results from hepatocyte loss of identity stemming from compromised expression of the hepatic CoRC TFs (Dubois et al, 2020a; Berasain et al, 2022).”

    The Key points and Conclusions link loss of liver function during chronic injury to impaired core liver transcription factors and loss of hepatocyte identity. The ‘Loss of hepatic function in liver disease’ section says persistent impairment creates conditions favourable to hepatocellular carcinoma, but does not establish that this mechanism causes liver-function breakdown in cancer itself. The indexed passages do not provide individual page numbers. (LLM, conf=0.84)

  • Hepatocyte partial loss of identity is a hallmark of diseased livers.

  • Loss of hepatocyte identity is a main feature of tumorigenesis and has broader pathophysiological relevance including loss of activity of severely injured livers.

    “Loss of hepatocyte identity is a main feature of tumorigenesis, but is now ascribed a broader pathophysiological relevance including loss of activity of severely injured livers (Berasain et al, 2022).”

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.
