The aryl hydrocarbon receptor (AHR) repressor (AHRR), an AHR-related basic helix-loop-helix/Per-AHR nuclear translocator-Sim protein, is regulated by an AHR-dependent mechanism and acts as a transcriptional repressor of AHR function.

We report here that, apart from induction of CYP1A1 and CYP1B1 expression and the corresponding enzymatic activity, both BaP and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) induced rat 3alpha-hydroxysteroid dehydrogenase (AKR1C9) expression and activity.

These improved procedures enhance long-term storage (2-12 months) and recovery of large quantities of healthy cells after cryopreservation, and maintain the differentiated functions of rat hepatocytes, compared to freshly isolated cells, as judged by viability (77-93%), adherence (77%) and metabolic functions of major cytochrome P450 isoforms CYP1A1/2, CYP2C6, CYP2D2, and CYP3A1/2.

This was achieved by comparing basal and inducible or metabolic activities of isoforms CYP1A1, CYP1A2, CYP2C6, CYP2D2, and CYP3A in rat hepatocytes that were cryopreserved with WPE, relative to fresh cells and those cryopreserved with DMSO.

Liver samples collected from all exposure groups were analyzed for gene (RARalpha, AhR2alpha, AhR2beta, CYP1A1, UGT1 and GSTpi) expression using real-time PCR and activity (7-ethoxyresorufin O-deethylase (EROD), UGT and GST) using biochemical methods with specific substrates.
