As depicted in Fig. 9d, Ingenuity Pathway Analysis showed key genes highly enriched in BC with CDKN2B-AS1, namely (1) RELA proto-oncogene, (2) prostaglandin-endoperoxide synthase 2 (PTGS2), (3) interleukin 6 (IL6), (4) vascular endothelial growth factor A (VEGFA), and (5) tumor necrosis factor-alpha (TNF). Here, PTGS2 is linked to breast cancer.
