Total RNA was isolated from cells or human tissues using
Trizol reagent (Invitrogen, Carlsbad, CA). The cDNA was generated from each 2 ug RNA sample using
All-in-One™ First-Strand cDNA Synthesis Kit (GeneCopoeia, Cat. No QP006). The temperature protocol for reverse transcription was: 28 ºC for 2 min, 42 ºC for 30 min, and 85 ºC for 5 min. cDNA was subjected to initial denaturation at 94˚C for 2 min, followed by 40 cycles at 95˚C for 15 s and 60–68 ºC for 30 s, after the end, it starts from 65˚C to 95 ºC, rising by 0.5 ºC per second, using the
BeyoFastTM SYBR Green qPCR Mix (Bio-Rad, Cat. No 1708882AP). The primers used in qRT-PCR are shown in Additional file
3: Table S2. The method was used for relative quantification and the quantifications were normalized by taking GAPDH as an internal reference. All experiments were repeated in three times.
