Further analysis using the TISIDB database to study the relationship between Annexin mRNA expression levels and the whole clinical stages of ovarian serous adenocarcinoma (Fig. 3) showed that the expression levels of ANXA1 (Fig. 3a, Spearman: ρ = 0.119, P = 0.0383), ANXA2 (Fig. 3b, Spearman: ρ = 0.139, P = 0.0157), ANXA4 (Fig. 3d, Spearman: ρ = 0.128, P = 0.0261), ANXA7 (Fig. 3g, Spearman: ρ = 0.153, P = 0.00758) and ANXA8 (Fig. 3h, Spearman: ρ = 0.15, P = 0.00927) increased significantly with advanced FIGO stages. Here, ANXA8 is linked to ovarian serous adenocarcinoma.
