Only transcripts that showed detectable expression in all three lines were considered. The number of transcripts with GO terms assigned for each test group is shown in parentheses following the group description. The reference group comprises the rest of the transcriptome. The p values for each GO term are: p < 0.0005 for single testing, FWER adjusted p < 0.1 and FDR < 0.1. See Materials and methods for details.
