Gene set enrichment analysis (GSEA) revealed that HALLMARK_G2M_CHECKPOINT, HALLMARK_MYC_TARGETS_V1, HALLMARK_E2F_TARGETS, and HALLMARK_E2F_TARGETS were differentially enriched in phenotypes with high LACTB expression, which may be important biological pathways in the pathogenesis of pancreatic cancer and warrant further study. Here, LACTB is linked to pancreatic neoplasm.
