1 μg RNA was reverse transcribed using a primeScript RT and DNA Eraser (TaKaRa, DRR047A) Reagent Kits and stored at −80 °C. Real time PCR was run in triplicate with 50 ng cDNA using FastStart Universal SYBR Green Master (Roche, 04913914001) and ABI7900HT. Relative differences were determined using the ΔΔCt approach. ΔΔCt = (Ctinfection−Ct18S rRNA)−(Ctunfection−Ct18S rRNA). The fold enrichment value is 2−ΔΔCt.
