CDK1 and lymphoid neoplasm: As shown in Figure 3(e), CDK1 expression in HNSC (P=0.0210), MESO (P=0.0307), READ (P=9.94E − 05), SARC (P=0.0043), STAD (P=1.53E − 13), and UCEC (P=2.06E − 10) was positively correlated with MSI, while lymphoid neoplasm diffuse large B-cell lymphoma (DLBC, P=0.0330) showed a negative correlation between CDK1 expression and MSI.
