Figure 5. Validation of expression levels of individual core genes in normal pancreas and PAAD tissues from the GEPIA database (A–K) DKK1, S100A2, CDA, KRT6A, ITGA3, GPR87, IL20RB, ZBED2, PMEPA1, CST6 and MUC16 were significantly up-regulated in PAAD when compared to normal tissues (P < 0. 01). Red * indicates P < 0. 01.
