Among the 10 core KEGG pathways in our ceRNA network, nine have already been associated with schizophrenia: cell cycle (41), spinocerebellar ataxia (42), apoptosis (43), ErbB signaling (44), focal adhesion (45), endocytosis (46), adhesions junction (47), Wnt signaling (48), and MAPK signaling (49). The gene discussed is EGFR; the disease is schizophrenia.
