PMID- 16777070 OWN - NLM STAT- MEDLINE DCOM- 20060821 LR - 20141120 IS - 0006-291X (Print) IS - 0006-291X (Linking) VI - 346 IP - 3 DP - 2006 Aug 4 TI - Effects of prototypical drug-metabolizing enzyme inducers on mRNA expression of housekeeping genes in primary cultures of human and rat hepatocytes. PG - 1033-9 AB - Quantitative real-time RT-PCR was used to investigate the effects of prototypical drug-metabolizing enzyme inducers rifampicin (Rif), dexamethasone (Dex), and omeprazole (Ome) on mRNA expression levels of the housekeeping genes beta-actin (ACTB), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), beta-glucuronidase (GUSB), hypoxanthine phosphoribosyltransferase 1 (HPRT1), peptidylprolylisomerase A (PPIA), TATA box binding protein (TBP), and transferrin receptor (TFRC) in primary cultures of cryopreserved human and rat hepatocytes. The mRNA levels of ACTB, GAPDH, GUSB, PPIA, TBP, and TFRC relative to HPRT1 in human hepatocytes were constant at all concentrations of inducers. However, the mRNA level of GAPDH relative to HPRT1 in rat hepatocytes was markedly increased by Rif. The mRNA levels of GAPDH, GUSB, PPIA, TBP, and TFRC relative to HPRT1 in rat hepatocytes were significantly increased by Dex. ACTB and HPRT1 are suitable internal controls for evaluating mRNA expression levels in primary cultures of human and rat hepatocytes after Rif, Dex, or Ome exposure.
