RNA was extracted using TRIzol reagent (Life Technologies), and reverse transcription was performed with 3 μg of total RNA using oligo(dT) and RevertAid Reverse Transcriptase (Thermo Scientific), according to the manufacturer’s instructions. Gene amplification was performed with SuperReal PreMix SYBR Green (TIANGEN) using an Applied Biosystems 7500 Fast Real-Time PCR System (Life Technologies), and the expression levels of all the genes were normalized to those of β-actin. Primers for each exon region of ZAP, NS1, and β-actin have been reported26 (link).
