Abstract

To clarify molecular mechanisms underlying liver carcinogenesis induced by aberrant activation of Wnt pathway, we isolated the target genes of beta-catenin from mice exhibiting constitutive activated beta-catenin in the liver. Adenovirus-mediated expression of oncogenic beta-catenin was used to isolate early targets of beta-catenin in the liver. Suppression subtractive hybridization was used to identify the leukocyte cell-derived chemotaxin 2 (LECT2) gene as a direct target of beta-catenin. Northern blot and immunohistochemical analyses demonstrated that LECT2 expression is specifically induced in different mouse models that express activated beta-catenin in the liver. LECT2 expression was not activated in livers in which hepatocyte proliferation was induced by a beta-catenin-independent signal. We characterized by mutagenesis the LEF/TCF site, which is crucial for LECT2 activation by beta-catenin. We further characterized the chemotactic property of LECT2 for human neutrophils. Finally, we have shown an up-regulation of LECT2 in human liver tumors that expressed aberrant activation of beta-catenin signaling; these tumors constituted a subset of hepatocellular carcinomas (HCC) and most of the hepatoblastomas that were studied. In conclusion, our results show that LECT2, which encodes a protein with chemotactic properties for human neutrophils, is a direct target gene of Wnt/beta-catenin signaling in the liver. Since HCC develops mainly in patients with chronic hepatitis or cirrhosis induced by viral or inflammatory factors, understanding the role of LECT2 in liver carcinogenesis is of interest and may lead to new therapeutic perspectives.

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.
