Abstract

Chronic liver inflammation is a crucial event in the development and growth of hepatocellular carcinoma (HCC). Compelling evidence has shown that interleukin-6 (IL-6)/gp130-dependent signaling has a fundamental role in liver carcinogenesis. Thus, in the present study we aimed to investigate the role of gp130 in hepatocytes for the initiation and progression of HCC. Hepatocyte-specific gp130 knockout mice (gp130 Δhepa) and control animals (gp130 f/f) were treated with diethylnitrosamine (DEN). The role of gp130 for acute injury (0–144 h post treatment), tumor initiation (24 weeks) and progression (40 weeks) was analyzed. After acute DEN-induced liver injury we observed a reduction in the inflammatory response in gp130 Δhepa animals as reflected by decreased levels of IL-6 and oncostatin M. The loss of gp130 slightly attenuated the initiation of HCC 24 weeks after DEN treatment. In contrast, 40 weeks after DEN treatment, male and female gp130 Δhepa mice showed smaller tumors and reduced tumor burden, indicating a role for hepatocyte-specific gp130 expression during HCC progression. Oxidative stress and DNA damage were substantially and similarly increased by DEN in both gp130 f/f and gp130 Δhepa animals. However, gp130 Δhepa livers revealed aberrant STAT5 activation and decreased levels of transforming growth factor-β (TGF β), pSMAD2/3 and SMAD2, whereas phosphorylation of STAT3 at Tyr705 and Ser727 was absent. Our results indicate that gp130 deletion in hepatocytes reduces progression, but not HCC initiation in the DEN model. Gp130 deletion resulted in STAT3 inhibition but increased STAT5 activation and diminished TGF-dependent signaling. Hence, blocking gp130 in hepatocytes might be an interesting therapeutic target to inhibit the growth of HCC.

  • IL-6 or gp130 knockout mice develop significantly fewer tumors in DEN-induced HCC model and have prolonged survival.

    “Indeed, IL-6 or gp130 knockout mice developed significantly less tumors in the diethylnitrosamine (DEN)-induced HCC model and prolonged survival [63, 64]”

    From The double-edged effects of IL-6 in liver regeneration, aging, inflammation, and diseases (2024) · cites this paper as [64]

    The Results section ('Ablation of gp130 in hepatocytes reduces HCC progression in male and female mice'; page unavailable) reports significantly fewer tumor nodules in male mice with hepatocyte-specific gp130 deletion 40 weeks after DEN treatment. The reduction in female mice was not statistically significant. The paper does not report prolonged survival, and its own experiment did not test IL-6 knockout mice. (LLM, conf=0.88)

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.
