By analyzing the expression correlation between KIF15 and cell cycle-related genes in 528 glioblastoma patients, KIF15 expression was found to be highly positively correlated with CCNA2, CDC25A and CDK2, moderately positively correlated with ANAPC1, CCND1 and CDK4, and weakly positively correlated with P300, CDK6 and RB1 (Supplementary Fig. 2A,B). This evidence concerns the gene ANAPC1 and glioblastoma.
