Cell cycle progression/proliferation (Cdk4, Clu, Id2, Mki67, Magoh, Myc, Pcna, Tcf3, Tp53), tumor cell mitosis (Mif, Plk1), DNA excision repair (Apex1, Ddb1, Hmgb1, Polb), DNA methylation (Dnmt3a, Dnmt3b), accumulation of colonocytes (Clu, Myc), tumorigenesis (Cd44, Cdk4, Ctnnb1, Esr1, Myc, Prkar1a, Tp53), Wnt-signaling pathway (Csnk1a1, Cskn1d, Cskn1e, Ctnnb1, Lef1, Myc, Nlk, Ppp2cb, Tcf3, Tcf4, Wif1). This evidence concerns the gene PCNA and neoplasm.
