DKK4 and colorectal cancer: By doing so, we found a correlation between CCNP expression and the expression of GPC3 (False discovery rate, FDR = 0.00849), FRZB (FDR = 0.048), DKK4 (FDR = 0.0201) and CTHRC1 (FDR = 0.447), which are all related to cancer growth, stemness and invasiveness, in among others hepatocellular, ovarian and colorectal cancers [41–48].
