The pGL4.32 and pGL4.75 were extracted separately according to the instructions and the transfection solution was prepared according to the requirements at the time of use. Cells in good growth condition were seeded in 96-well plates at a density of 3 × 105 cells/mL. 0.1, 1, 10 μM polydatin and 10–2 μM Dexamethasone in TNF-α medium, and then the reporter gene activity was tested according to the procedure provided by the reagent company.
