abstract = "Recently, we reported that treatment with the mouse agonist of the constitutive androstane receptor (CAR), 1,4-bis benzene[2-(3,5-dichloropyridyloxy)] (TCPOBOP; a well-known hepatomitogen), reduced PTEN protein levels, leading to Akt activation. Hence, the present study was performed to demonstrate the role of CAR in PTEN regulation and liver growth. Liver hyperplasia caused by CAR activation was confirmed to be mediated by a decrease in PTEN protein level and the activation of the Akt signalling pathway in the liver of mice. Treatment with the CAR agonist decreased the PTEN levels and increased Foxm1 levels, which correlate with the elevated expression of the FoxM1 target gene, Nedd4-1, an E3 ligase involved in PTEN ubiquitination, and the promotion of degradation. The increase in Nedd4-1 levels was accompanied by an increase in CAR-mediated accumulation of Foxm1 on the Nedd4-1 gene promoter. Therefore, these results provide evidence that a notable function of CAR is its liver growth promotion effect, which is accompanied by FoxM1-Nedd4-mediated repression of PTEN and Akt pathway activation.",
