Figure 1. RIOK3 protein is highly expressed in PDAC tissues and associated with poor prognosis. (A) ROC curve of RIOK3 mRNA for prediction PDAC in TCGA and GTEx datasets (AUC=0.954, 95%CI:0.921-0.969) (n=350, 171 Normal and 179 Tumor). (B) Representative IHC staining of RIOK3 and IHC analysis of RIOK3 expression in PDAC and paired adjacent normal tissue (n=46; p=0.004). Paired samples Wilcoxon test. (C) Representative IHC staining of RIOK3 and IHC Immunohistochemical analysis of RIOK3 expression in different stages of PDAC tissues (n=46; 15 Stage I, 21 Stage II, 3 Stage III, and 7 Stage IV; F = 17.331, P < 0.001). One-way ANOVA test. (D) Kaplan–Meier curves of DFS and OS analysis of RIOK3 expression in PDAC patients (n=46, 28 high-RIOK3 and 18 low-RIOK3). The star (*) symbol denotes the level of statistical significance: * p < 0.05, ** p < 0.01, *** p < 0.001, ns no significance.
