RT-qPCR was performed using a Bio-Rad CFX96 Real-Time system (C1000 Touch Thermal Cycle, Bio-Rad, Singapore).Reactions were performed in a 10 uL reaction mixture containing 5 uL PowerUp SYBR Green Master-Mix 2X (A25779, Applied Biosystems), 2 uL of 10 ng cDNA, 1 uL of each specific primer (10 uM), and 1 uL of molecular-grade water.The PCR conditions were as follows: 50?C for 2 min; 40 cycles of 95?C for 2 min, 95?C for 15 s, 57?C for 15 s, 72?C for 1 min; and an extra step of melting analysis for each sample at 65?C for 5 s and 95?C for 5 s.Gene amplification was performed in duplicates, and each PCR run was performed thrice.A negative control (ultrapure water) was used in each assay.
