Abstract

The cause of organ failure is enigmatic for many degenerative diseases, including end-stage liver disease. Here, using a CCl4-induced rat model of irreversible and fatal hepatic failure, which also exhibits terminal changes in the extracellular matrix, we demonstrated that chronic injury stably reprograms the critical balance of transcription factors and that diseased and dedifferentiated cells can be returned to normal function by re-expression of critical transcription factors, a process similar to the type of reprogramming that induces somatic cells to become pluripotent or to change their cell lineage. Forced re-expression of the transcription factor HNF4α induced expression of the other hepatocyte-expressed transcription factors; restored functionality in terminally diseased hepatocytes isolated from CCl4-treated rats; and rapidly reversed fatal liver failure in CCl4-treated animals by restoring diseased hepatocytes rather than replacing them with new hepatocytes or stem cells. Together, the results of our study indicate that disruption of the transcription factor network and cellular dedifferentiation likely mediate terminal liver failure and suggest reinstatement of this network has therapeutic potential for correcting organ failure without cell replacement.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • MPH dedifferentiation can only be partially inhibited by combined inhibition of multiple dedifferentiating signaling pathways or by forced expression of supra-physiologic amounts of HNF4A.

    “previous reports indicated that MPH dedifferentiation could only be partially inhibited when using combined inhibition of multiple dedifferentiating signaling pathways (Sun et al, 2019; Xiang et al, 2019) or through forced expression of supra‐physiologic amounts of the Hep‐ID TF HNF4A (Nishikawa et al, 2015; Tafaleng et al, 2021; Yang et al, 2021).”

    From An extended transcription factor regulatory network controls hepatocyte identity (2023) · cites this paper as Nishikawa et al, 2015

    For the HNF4A portion attributed to Nishikawa et al., the Results say forced HNF4α re-expression reversed hepatocyte dedifferentiation in vitro, and the Discussion says hepatocytes could be completely corrected. The Discussion also says forced re-expression generated only 0.01% of the endogenous HNF4α level, contrary to the claim that supra-physiologic amounts were required. (LLM, conf=0.92)

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.
