The TRIzol Reagent (Invitrogen) was used for extract total RNA from tissues and cells. RNA was reversely transcribed into cDNA using a miScript II RT kit (TaKaRa, Biotechnology Ltd., Dalian, China) and then the real-time qPCR was performed using a Premix Ex TaqTM II (TaKaRa) on an ABI PRISM 7500 real-time PCR System. Relative gene expression was determined by the 2-ΔΔCt method. The primers are listed in Table , in which U6 and GAPDH were set as the internal references for miRNA and mRNAs, respectively.
