"The raw data (.pair file) was subjected to RMA (Robust Multi-Array Analysis; Irizarry et al. Biostatistics 4(2):249), quantile normalization (Bolstad et al. Bioinformatics 19(2):185), and background correction as implemented in the NimbleGen Deva software, version 1.2 (Roche NimbleGen, Inc.)."	"data_processing.1"
"Total RNA was extracted using the RNeasy Mini kit (Qiagen) and DNA was removed by on-column DNase digestion with the RNase-Free DNase set (Qiagen). RNA  concentration was measured by SpectorPhotometer(NonoDrop)."	"extract_protocol_ch1.1"
