Figure 1. Identification of pseudogene AK4P1 as a potential regulator in PDAC. (A) The flow-process diagram for screening pseudogene AK4P1. (B) Expression of 19 potential DEPs in PDAC and normal pancreas tissues from TCGA and GTEx data. (C) Expression of 5 potential DEPs in PDAC and normal pancreas tissues. (D) Prognostic role (OS) of 5 potential DEPs in PDAC. (E) Prognostic role (DFS) of 5 potential DEPs in PDAC. (F) Expression of 5 potential DEPs among major stages in PDAC. Abbreviation: HR: hazard ratio; Three horizontal lines in the box plot represent minimum, median and maximum, respectively; *P < 0.05.
