In addition, Cell division cycle 20 (CDC20), Cyclin-dependent kinase 4 (CDK4), minichromosome maintenance 6 (MCM6), MAD2L1, minichromosome maintenance 2 (MCM2) and minichromosome maintenance 5 (MCM5) were leading genes that intersected in these four pathways, and their mRNA expression levels were positively correlated with LACTB in most normal and cancer tissues. Here, MCM6 is linked to cancer.
