Subsequent thermal cycling was performed at 55°C for 15 min for reverse transcription, followed by 95°C for 30 s and then 45 cycles of 95°C for 10 s, 60°C for 35 s. Fluorescence readout were taken after each cycle, and the threshold cycle (Ct) was calculated by the Bio-Red analysis system based on plotting against the log10 fluorescence intensity. The oligonucleotide primers and probes were synthesized by GENEWIZ (Suzhou, China), and corresponding sequences are shown in Table 1 . Table 1 . Sequences of primers and probes for RT-PCR.
