Abstract
- Abstract: The nuclear receptor constitutive active/androstane receptor CAR is a drug-sensing transcription factor. Upon activation by various drugs such as phenobarbital (PB), CAR translocates from the cytoplasm into the nucleus to regulate the genes that encode enzymes and proteins involved in hepatic metabolism. Here, we have shown the presence of CAR at the cell membrane of mouse livers, using Car +/+ and Car −/− mice. Levels of the cell membrane CAR increased after PB treatment. The CAR exists as a large approximately 160kDa complex. Thus, CAR undergoes PB-induced translocation to the cell membrane, indicating that CAR may exert a non-genomic action. [Copyright &y& Elsevier]
