The results showed that compared with normal tissues, sixteen proteins (ANGPTL1, BCHE, BNC2, CHRNA3, CNN1, CPED1, CYP1B1, FHL1, MYL9, PDLIM3, PRG4, RNF150, SELP, SPARCL1, SYNC, VIP) were significantly overexpressed in tumour tissues (Fig. 6, p < 0.05). The gene discussed is BNC2; the disease is neoplasm.
