MH7A cells were seeded in 6-well plates at 1 × 10
6 cells/well for 24 h. The cells were pretreated with
AG490/GEN (Sigma–Aldrich) at indicated concentrations for 2 h and then stimulated with
TNF-α (10 ng/mL; R&D Systems, Minneapolis, MN, USA) or
IL-6 (50 ng/mL; Sigma–Aldrich) for 24 h. According to the manufacturer's instructions, total RNA of the cells was extracted using the commercial total RNA miniprep kit (Corning, Inc., Axygen, NY, USA). Then, each RNA sample was reverse transcribed using a complementary DNA (cDNA) synthesis kit according to the manufacturer's protocol. qPCR analysis was performed using
SYBR Green PCR Premix Ex Taq II reagents (Takara Bio Inc., Kusatsu, Japan) on a
Light Cycler 480 II real-time system (Roche, Mannheim, Germany). Glyceraldehyde 3-phosphate dehydrogenase (GAPDH), a house-keeping gene, was used for normalising the result of qPCR.
