The majority of the downregulated genes, including ANKRD12, ASPM, CDC25A, CDCA4, CENPE, CHEK1, DLGAP5, DPP4, DTL, EBP, E2F8, FBXO5, FOLH1, HIST1H4C, HSP90B1, ITGAV, KIF14, MAD2L1, METAP2, NRIP1, POLA1, PRIM2, SKP2, TOP2A, TOP2B, TPR, and UHRF1, are associated with cell cycle function and cancer development [26, 27]. This evidence concerns the gene PRIM2 and cancer.
