FEN1 and neoplasm: We further analyzed the correlation between MND1 and cell cycle-related factors, and the results suggested that there was a significant relationship between MND1 and CDC25A, CDC25C, CDC45, CHAF1A, CDK1, FEN1, MCM2, MCM3, and CDT1, which further proved that MND1 is a crucial gene associated with tumor progression (Fig. 4C).
