Data extraction and raw data normalization were performed using the CodeLink Gene Expression Analysis v4.0 software. Normalization was performed by the global method. The threshold was calculated using the normalized signal intensity of the negative controls supplemented by 3 times the standard deviation. Spots with signal intensity below this threshold were referred to as ''absent''. Obtained datasets were deposited in GEO database in accord to MIAME guidelines (Accession number: GSE 32902: GSM813064, GSM813065, GSM813066 and GSM813067). Finally, data were converted to the excel format and data analysis was performed by using the Gene Spring v7.0 software from Agilent and pariwise comparisons were performed between infected and uninfected samples.
