Dexamethasone-induced transcripts of breast cancer resistance protein (Bcrp) and multidrug resistance associated protein 2 (Mrp2) in brain endothelial cells. RT-PCR shows that dexamethasone treatment (24 h) increased transcription of Bcrp and Mrp2 in primary rat brain endothelial cells in a concentration-dependent manner. Thirty cycles were used for gene amplification. Quantitative analysis by densitometry of three different experiments is also shown. **P < 0.01 vs. untreated cells.
