CDKN1A and cancer: These data support the notion that DNA damage destabilizes hnRNPA0 mRNA leading to downregulation of hnRNPA0 protein in wild‐type p53 cancer cells.[11] Moreover, in agreement with the reported roles of p53/p21 in the downregulation of hnRNPA0 after DNA damage in wild‐type p53 cancer cells,[11] knockdown of either p53 or p21 in HCT116 and RKO cells diminished the reductions in hnRNPA0 mRNA after oxaliplatin treatment or UV irradiation (Figure S5i,j, Supporting Information).
