Important drivers of p27-related cell cycle dysregulation that were upregulated in OCCC with concurrent endometriosis include SKP2 (S-phase kinase-associated protein 2, log2 fold-change = 1.3, P = 1.1e-2), CKS2 (CDC28 protein kinase regulatory subunit 2, log2 fold-change = 2.2, P = 6.6e-9), CCNA2 (Cyclin A2, log2 fold-change = 1.7, P = 2.9e-3), and CCNE1 (Cyclin E1, log2 fold-change = 5.2, P = 8.5e-10). The gene discussed is SKP2; the disease is endometriosis.
