Downregulated genes were mainly enriched in the gene sets Fischer, DREAM targets (4.8 × 10−146), Kinsey, targets of EWSR1-FLI1 fusion up (4.3 × 10−121) Dodd, nasopharyngeal carcinoma down (6.2 × 10−117), Pujana, BRCA1 pcc network (normal tissues) (8.1 × 10−114), Gobert, oligodendrocyte differentiation up, and hay bone marrow erythroblast (1.6 × 10−108). This evidence concerns the gene BRCA1 and nasopharyngeal carcinoma.
