CBX3 and ovarian carcinoma: Increases in CBX1 (Figure 1A and 1B), CBX2 (Figure 1C and 1D) and CBX3 (Figure 1E and 1F) at the transcriptional level were all strongly related to short OS and PFS for ovarian cancer patients (OS: CBX1: HR = 1.38 (1.20 - 1.59), P = 0.0000; CBX2: HR = 1.35 (1.10 - 1.66), P = 0.0045; CBX3: HR = 1.25 (1.09 - 1.44), P = 0.0019; PFS: CBX1: HR = 1.31 (1.14 - 1.50), P = 0.00012; CBX2: HR = 1.44 (1.16 - 1.79), P = 0.0010; CBX3: HR= 1.19 (1.05 - 1.35), P = 0.0069).
