Total RNA was isolated using TRIzolTM (Invitrogen), and cDNA was synthesized using 2 μg of total RNA with SuperScript® III First-Strand Synthesis System, according to the manufacturer’s protocol (Invitrogen). Real-time PCR was performed on LightCycler 480® (Roche), using SYBR Green I Master Mix. The primer set sequences are provided in Supplementary Table S1.
Total cell lysates were prepared, and western blot analyses were conducted as described previously [32 (link)]. Antibodies are listed in Supplementary Table S2. Signals were visualized with Western Lighting Plus-ECL Chemiluminescent Reagents (Perkin Elmer, Waltham, MA, USA), and the intensity of the resulting bands was quantified by ImageJ software (NIH, Bethesda, MD, USA).
