Experimental Conditions
For the analysis of CYP3A4 expression, ~500,000 DPX2 cells were seeded on a 12-well plate and cultured for 24 h. Cells were treated with herbal extracts or chemicals for another 24 h and then washed with PBS. Total RNA of the cells was extracted using TRIzolTM Reagent and 2 µg of them was used for reverse transcription. Quantitative RTPCR was performed using Power SYBR Green PCR Master Mix (Applied Biosystems by Thermo Fisher Scientific, Warrington, UK). mRNA levels of CYP3A4 were normalized to Gapdh.
