In order to show the impact of CK1 isoforms on tumor progression we analyzed the survival of different cancer patients (17 types of cancer) depending on the gene expression levels of the three CK1 isoforms α, δ and ε using the PPISURV database [96], This database includes 45 expression studies with approximately 8000 patient survival data sets. This evidence concerns the gene CSNK1A1 and cancer.
