Additionally, we performed a correlation analysis between these genes and BIRC2 expression in the PAAD-TCGA dataset using GEPIA2, which revealed a positive correlation between BIRC2 expression and NRAS, RBPJ, UBE2 N, ZWINT, and MDM2 (Supplementary Fig. 6 A). This evidence concerns the gene BIRC2 and pancreatic adenocarcinoma.
