Pathway annotation analysis of the “core tumor-specific” CUGs identified “cell cycle/division,” “glycolysis,” “p53,” and “progesterone-mediated oocyte maturation” (consisting of CCNB1, CDK1, HSP90AA1, MAD2L1, CCNB2, BUB1, CCNA2, CDK, and CDC25B genes) among pathways that are low in normal pancreas but elevated in PDAC (Figure 3D). The gene discussed is CCNB2; the disease is neoplasm.
