Enrichment analysis shows that 143 YY highly expressed unigenes were enriched in 192 pathways, and most of the DEGs were assigned to pathways in cancer (16 DEGs, ko05200), PI3K-Akt signaling pathway (12 DEGs, ko04151), phagosome (12 DEGs, ko04145), neuroactive ligand-receptor interaction (11 DEGs, ko04080), cytokine-cytokine receptor interaction (10 DEGs, ko046760), tuberculosis (10 DEGs, ko05152) and focal adhesion (10 DEGs, ko4510). The gene discussed is PIK3CB; the disease is cancer.
