Total RNA was generated using
Trizol reagent (Life Technologies, Carlsbad, CA), followed by double DNase treatment and column purification using Qiagen
RNeasy Clean-up (Qiagen, Germantown, MD). The Invitrogen
Superscript III First-Strand Synthesis System (Invitrogen, Waltham, MA) was used for cDNA synthesis and
TaqMan 5700 Sequence Detection System (Applied Biosystems, Foster City, CA) was used for qRT-PCR. All PCR reactions were run in triplicate. The amplified transcripts were quantified using the comparative ΔCT method as described (Zhang et al., 2007 (
link)). cDNA and primers for MAPK11, 12, 13, and 14 and GAPDH (see
Supplementary Table S1) were added to
SYBR Green PCR Master Mix (SYBR Green I Dye, AmpliTaq DNA polymerase, deoxynucleotides with deoxyuridine triphosphate, and optimal buffer components: Applied Biosystems) and subjected to PCR amplification (1 cycle at 95°C for 3 minutes, 35 cycles at 95°C for 15 seconds and 55°C for 30 seconds, and 1 cycle at 50°C for 2 minutes).
