In addition, 4 biomarkers (Cav-1, PDL+CD68-, LASS2, MCM7) were associated with OS [28, 50, 61, 112], 10 biomarkers (TXNIP, UbcH10, PCNA, CDK4, CDK6, pRB, p18, Cox-2, TIMP-2, and AKT2) with RFS [33, 56, 58, 64, 69, 99, 108], and 11 biomarkers (KPNA2, CRM1, EGFR ECD Ab, TGF-α, CD20+, AKAP12, RB1S780 phosphorylation, EZH2, PR+Bcl-2-, hENT1, and dCK) with PFS of meningioma patients [47, 49–51, 90, 91, 98, 110, 114]. The gene discussed is PCNA; the disease is meningioma.
