QPCR
cDNA was diluted 1:10 with RNase-free water. The TaqMan or SYBR Green detection system was used with commercially available probes (Supplementary Table 3 for TaqMan and Supplementary Table 4 for SYBR Green). QPCR analysis was conducted using a QuantStudio™ 6 real-time PCR system (Invitrogen). Results were analysed using QuantStudio™ software (Life Technologies, Version 1.1). Cycle threshold (Ct) values were normalised to the housekeeping gene Glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Relative gene expression was calculated using the comparative CT method .
