In adenoma compared to normal top hub genes are APOE (7), NR3C1 (4), and NMU (4), in carcinoma compared to normal top hub genes are AGT (10), BCL2 (10), AURKA (9), MMP3 (6), CDC6 (6), TPX2 (6), PRKACB (6), UB2C (5), SULT1A1 (4), KLF4 (4), ECT2 (4), and MMP1 (4), and in carcinoma compared to adenoma top hub genes are COL3A1 (6), COL1A2 (6), SPARC (5), DCN (5), and SPP1 (4). Here, KLF4 is linked to carcinoma.
