Abstract

Unlabelled In the adult liver, 1,4-bis[2-(3,5-dichloropyridyloxy)]benzene (TCPOBOP), an agonist of the constitutive androstane receptor (CAR, NR1I3), produces rapid hepatomegaly in the absence of injury. In this study, we identify c-Myc as a gene induced by CAR and demonstrate that TCPOBOP-induced proliferation of hepatocytes depends on c-Myc function. Moreover, the TCPOBOP-induced cell cycle program (Cdc2, cyclins, MCM proteins, Cdc20, and genes implicated in the spindle assembly checkpoint) is severely impaired in c-Myc mutant livers. Strikingly, many of these genes overlap with a program controlled by the forkhead transcription factor FoxM1, known to control progression through S-phase and mitosis. Indeed, FoxM1 is also induced by TCPOBOP. Moreover, we show that c-Myc binds to the FoxM1 promoter in a TCPOBOP-dependent manner, suggesting a CAR --> c-Myc --> FoxM1 pathway downstream of TCPOBOP. Conclusion Collectively, this study identifies c-Myc and FoxM1 mediated proliferative programs as key mediators of TCPOBOP-CAR induced direct liver hyperplasia.

  • CAR's pro-proliferative role in liver is mediated through induction of c-Myc, Foxm1, and cyclin D1, and modulation of β-catenin and YAP signaling pathways.

    “Prior studies have focused primarily on the pro-proliferative role of CAR in the liver, mediated through the induction of factors such as cellular-myelocytomatosis oncogene (c-Myc),15 forkhead box m1 (Foxm1),15 and cyclin D1 (Ccnd1),16 as well as modulation of β-catenin17,18 and Yes-associated protein19, 20, 21, 22 signaling pathways.”

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.
